Understanding the Basics

What is arrow spine?

Spine is a measure of an arrow's stiffness: how much the shaft bends under force. Manufacturers determine static spine by supporting an arrow at two points and hanging a standard weight at the center.

The amount the arrow deflects (bends) under that weight is measured in thousandths of an inch. For example, a carbon arrow labeled "500 spine" bends 0.500" under the test weight.

Key insight

A lower spine number means a stiffer arrow (less flex). So a 400 spine shaft is stiffer than a 600 spine shaft.

Wood arrows use a spine in pounds instead (e.g., "45-50# spine"). It comes from a different test, a 2 lb weight on a 26" span, and a higher number means a stiffer shaft, the opposite of carbon numbers.[1] It is not simply your bow weight: 3Rivers' chart puts a 45 lb recurve with a 28" arrow and 125 grain point at 40-45#.[2]

Static vs. dynamic spine

Static spine is the laboratory measurement on the arrow label, but dynamic spine is how the arrow actually behaves when shot from your bow.

On release, every arrow flexes and oscillates. This is called the archer's paradox. Dynamic spine depends on multiple factors:

Draw weight

Higher draw weight causes more arrow flex, requiring stiffer spine.

Arrow length

Longer arrows flex more than shorter ones of the same static spine.

Point weight

Heavier points make arrows act softer (more flex) on release.

Release style

Finger release causes more initial flex than a mechanical release aid.

Critical for Accuracy

Why spine matters

Using the correct spine is critical for safety and accuracy. If your arrows are too weak (under-spined) for your bow, they will flex excessively upon release.

For right-handed shooters

Shooting with fingers, an under-spined (weak) arrow tends to hit right of the mark and an over-spined (stiff) arrow left. In a bare-shaft test, unfletched arrows that land right of your fletched ones are too weak, and ones that land left are too stiff. Left-handed archers see the opposite.[3]

With a release aid the arrow bends mostly up and down instead, so release shooters may need the opposite adjustments.[3]

A properly spined arrow flexes just the right amount as it leaves the bow, then stabilizes into straight flight. Your groups get tighter and more consistent.

The archer's paradox

When you release a bowstring with your fingers, the arrow is pushed forward but the back of the arrow (at the nock) wants to go around your fingers. This creates a flexing motion that causes the arrow to bend around the bow's riser.

Example: a 30 lb bow

A 30 lb recurve needs a relatively flexible shaft: Easton's 2026 target chart gives 800-700 for a 28" carbon arrow, 720-625 at 29" and 675-600 at 30", all with a 100 grain point.[4] Other makers' charts give different answers. If you use an arrow that's far too stiff (say 400 spine rated for 60 lb bows), the 30 lb bow won't flex the arrow enough: the arrow will fly left and the bow will "fight" the arrow.

Start with the bow

Your bow's real draw weight

The label on your limbs, such as 30# @ 28", is the bow's marked weight: what it pulls when drawn to 28 in (71 cm). The 28 in is a convention. Recurves and longbows are all weighed and marked at that draw so they can be compared.[5]

Your arrows never feel the marked weight. They feel the weight at your full draw. Draw past 28 in and the bow pulls harder; stop short of it and the bow pulls less. That second number, your real draw weight, is the one every spine chart asks for.[2][6]

The AMO correction

The industry standard from AMO (the body now called the ATA) gives a simple correction for non-compound bows. Divide the marked weight by 20. Add that amount for every inch you draw past 28 in, and subtract it for every inch short.[5]

The formula

Weight at your draw = marked weight + (your draw length − 28) × (marked weight ÷ 20)

Example: a 30# @ 28" bow drawn to 26 in gives 30 + (26 − 28) × (30 ÷ 20) = 30 − 3 = 27 lb (12.2 kg).

The step is a fixed share of the bow's weight, one twentieth (5%) per inch, so heavier bows change faster.

Real draw weight at four draw lengths, by the AMO correction
Your draw length Bow marked 30# @ 28" (1.5 lb per inch) Bow marked 40# @ 28" (2 lb per inch)
26 in (66 cm) 27 lb (12.2 kg) 36 lb (16.3 kg)
27 in (68.6 cm) 28.5 lb (12.9 kg) 38 lb (17.2 kg)
29 in (73.7 cm) 31.5 lb (14.3 kg) 42 lb (19.1 kg)
30 in (76.2 cm) 33 lb (15.0 kg) 44 lb (20.0 kg)

Real limbs only roughly follow this rule, and a bow can be up to 2 lb (about 1 kg) off its marked weight and still meet the industry standard.[2] Treat any formula as a starting point, not a measurement.

More detail: other rules of thumb, and takedown limbs

Other estimates run from 1.5 to 3 lb per inch: 1.5 to 2 lb in World Archery's coaching manual,[7] a flat 2 lb at Bear Archery,[8] and roughly 2 to 3 lb on the 3Rivers charts.[2]

Takedown recurves add two more variables. On Hoyt's takedowns, a 23 in riser pulls about 2 lb more than the weight marked on the limbs.[9] One limb maker weighs its target limbs with the tiller bolts at their middle setting and its nature limbs at maximum, so turning the bolts moves you off the label.[10] Check how your limb maker rates them.

Why the charts want the real number

Spine chart rows are narrow: on Easton's target chart one row covers 40-43 lb and the next 44-47 lb,[4] so a few pounds of error can put you on the wrong row and the wrong arrows.

Weigh it if you can

A bow scale reads the pull at your own full draw, and a pro shop can weigh your bow for you.[6] Write the reading down next to your draw length: you'll need both every time you buy arrows or limbs.

Measuring your draw length

Draw length has a standard definition too. AMO defines it as the distance, at full draw, from the nocking point on the string to the pivot point of the grip, plus 1¾ in.[5]

For a first estimate, measure your wingspan from fingertip to fingertip and divide it by 2.5.[11][12] A 60 in (152 cm) wingspan gives a 24 in (61 cm) draw, and a 73 in (185 cm) wingspan gives 29.2 in (74 cm).[11][12]

Treat that as a starting point. Once you can shoot with steady form, measure your real draw.

More detail: where the 1¾ in comes from, and measuring at the clicker

The added 1¾ in keeps draw length in step with the marking standard. AMO's 28 in draw is 26¼ in (66.7 cm) from the string to the pivot point.[5]

World Archery uses the same definition and gives the extra as 45 mm.[7]

On an Olympic recurve, one limb maker's method is to mark the arrow at the pressure button as it comes through the clicker, measure from the mark to the nock, and add 1.75 in.[10]

Compounds work differently

The AMO correction is for "a conventional bow", which means a non-compound one.[5] On a compound, draw weight and draw length are settings on the bow, not results of how far you pull. Easton's compound charts ask for the bow's peak weight and its speed rating, not the lower weight you hold at full draw.[4]

More detail: how a compound's weight and draw length are set

On most compounds the limb bolts set the peak weight, usually anywhere down to about 10 lb below the maximum, and the cam or a module on it sets the draw length.[13][14]

The IBO defines a bow's shooting weight as its "maximum draw or thrust weight, as set up".[15]

Draw length matters even more on a compound, because you can't simply draw a little less, and some models allow only limited adjustment.[16]

Reference Charts

Spine selection tables

These starting points are for a recurve shot with fingers, a 29" arrow and a 100 grain point. They come from Easton's 2026 target chart and 3Rivers Archery's traditional charts.[2][4] Use your bow's actual draw weight at your draw length, not only the number on the limbs.[6]

For a heavier point, add 3 lb to your bow weight for every 25 grains over 100 before you read Easton's chart, and for wood/glass beginner limbs, subtract 5 lb.[4] The charts often disagree (here is why), so treat every number here as the starting point for a test shaft.

60 lb 400-340 400 2314, 2413, 2315 55-60#

A dash means the chart has no row for that weight. 3Rivers adds 5 lb for Fast Flight strings. With a 125 grain point, read its 125 grain column, which runs one 5 lb row stiffer: a 35 lb bow goes from 30-35# to 35-40#.[2]

Carbon, aluminum or wood

Carbon arrows

Popular Choice

Carbon arrows use the deflection number as the spine. They're very consistent and resilient: carbon shafts don't bend permanently.

  • Very durable and consistent
  • Can cut shorter to stiffen dynamic spine
  • Inspect and flex every arrow before each shot, not only after hard impacts, and discard any that crack[4][17]

Aluminum (aluminium) arrows

Target Favorite

Easton's XX75 series uses a four-digit code (e.g., 1916). First two digits = approximate outside diameter in 64ths of an inch, last two = wall thickness in thousandths of an inch.[18]

  • Very straight and uniform
  • Can bend but be straightened
  • Great consistency, lower cost

Wood arrows

Traditional

Wood spine is given in a poundage range (e.g., "40-45# spine"). Wood spine is quoted for a 28" arrow and changes by about 5# per inch: a shaft that spines 50# at 28" acts like 45# at 29" and 55# at 27". So for each inch over 28", go about 5# stiffer; for each inch under, about 5# weaker.[19]

  • Classic traditional aesthetic
  • Quiet off the bow
  • Can warp with humidity
Pro tip

When more than one size fits a recurve, pick the weaker one.[4] You can still fine-tune afterwards: a heavier point or a longer arrow makes the arrow act weaker, and a shorter arrow makes it act stiffer.

Spine charts

Why spine charts disagree

We gave one bow to six spine charts and calculators on the same day: a 30 lb (13.6 kg) recurve with wood/glass beginner limbs, a 28 in (71 cm) draw, a 29 in (74 cm) arrow and 100 gr (6.5 g) points, with a Dacron string where a tool asked. Three arrow makers' charts answered 500, 600 and 800-700.[20][21][22][23] A traditional shop's arrow builder said 800-900, an online calculator said 820, and a fourth maker's tool gave no number at all.[24][25][26]

None of these tools explains why its number differs from the others. The spread is not random, though: each chart was built for a particular kind of bow and arrow, and those assumptions decide the answer.

What each chart assumes

Easton target chart

Target recurve and compound
  • Recurve rows assume carbon competition limbs, a finger release and 100 gr glue-in points.[4]
  • Wood/glass beginner limbs: read the chart 5 lb lighter.[4]
  • Points: add 3 lb of bow weight per 25 gr (1.6 g) over 100 gr, and subtract 3 lb per 25 gr under.[4]
  • If the range covers several sizes, pick the weaker side.[4]
  • Compound rows assume peak weight, a release aid and a 301-320 fps speed rating.[4]

Easton hunting chart

Compound first
  • Built around compounds with a release aid, a 301-340 fps ATA rating and 100 gr screw-in points.[4]
  • Adds traditional recurve and longbow columns for finger shooters, read at actual bow weight at your draw.[4][6]
  • Arrow length runs to the end of the shaft, not including the point or insert.[4]
  • Compound with fingers: add 5 lb.[4] Brace height under 6.5 in (16.5 cm): add 5 lb.[6]

3Rivers charts

Traditional
  • Weight is actual peak bow weight at your draw length, with a finger release.[2]
  • One column per point weight: 100, 125, 150, 175 and 200 gr for carbon; 100, 125, 145, 160 and 190 gr for wood and aluminum. 3Rivers calls 125 gr the most common.[2]
  • The header reads "+5 for Fast Flight® bow strings". That implies the charts are set for Dacron, though 3Rivers does not say so outright.[2]
  • Separate columns for recurves and center-shot longbows, and for longbows and self bows. Carbon sizes refer to Easton spines.[2]

One bow, every chart

Here is the same bow read off every chart this guide's fit finder uses. We entered it as an Olympic-style takedown, shot with fingers, for target use.

One bow, six chart readings: 30# @ 28" takedown recurve, wood/glass limbs, 28 in draw, 29 in arrow, 100 gr point, fingers, Dacron string (computed by this guide's calculator from the published charts)
Chart Weight it reads Where it lands Answer
Easton target chart, carbon[4] 25 lb (30 lb minus 5 for wood/glass limbs) Row 21-26 lb, 29 in column 800-700
Easton hunting chart, traditional recurve column, carbon[4] 30 lb Row 29-32 lb, 29 in column 500-400
3Rivers carbon, recurve / center-shot[2] 30 lb Below the lightest row (the 100 gr column starts at 32-36 lb) Off the chart: no answer
Easton target chart, aluminum[4] 25 lb (30 lb minus 5 for wood/glass limbs) Row 21-26 lb, 29 in column 1816 or 1814
3Rivers aluminum, recurve / center-shot[2] 30 lb Below the lightest row (the 100 gr column starts at 31-35 lb) Off the chart: no answer
3Rivers wood, recurve / center-shot[2] 30 lb Below the lightest row (the 100 gr column starts at 31-35 lb) Off the chart: no answer

Easton's web selector gives the same 800-700 as its target chart.[23] Its hunting chart says 500-400 for the same bow: its traditional columns sit on a chart built for hunting arrows with screw-in points, and the 5 lb deduction for training limbs is printed only with the target chart.[4]

None of these answers is the right one. Each is a starting point, and only shooting the arrows settles it.

The real conflict: longbows

Most disagreements shrink once you match the chart to your bow. One does not. For longbows, Easton's current chart and 3Rivers move in opposite directions. Easton's current hunting chart gives a longbow the spine of a recurve about 20 lb heavier: a stiffer arrow.[4] The 3Rivers charts give longbows and self bows the arrow of a lighter recurve: a weaker one.[2]

Every other chart we checked either moves a longbow toward a weaker arrow or treats it like a recurve. Only Easton's current chart goes stiffer, and it prints no reason.[4]

More detail: the longbow evidence, chart by chart

Easton's current hunting chart offsets its longbow column from its recurve column. A 12-16 lb longbow sits on the same row as a 33-36 lb recurve, and the offset of about 20 lb runs all the way down the chart.[4]

The 3Rivers shift toward a lighter recurve is 5 lb on the wood and aluminum charts, where a 41-45 lb longbow reads like a 36-40 lb recurve at 100 gr, and about 18-21 lb on the carbon chart.[2] A center-shot longbow uses the recurve columns instead.[2] Most recurves are cut to center or past it, and most longbows slightly less than center,[1] so with 3Rivers the cut of your bow's shelf decides the column, not the name of the bow.

Easton's own earlier chart, still shown on its hunting shaft selector page, offsets the longbow column the other way: a 50-55 lb longbow sits on the row of a 32-36 lb recurve, so a longbow gets the arrow of a lighter recurve.[6]

Four archery retailers' charts agree, moving a longbow toward a weaker arrow by about 5 to 18 lb.[27][28][29][30]

Gold Tip uses one chart for recurves and longbows alike,[20] and Bear Archery's tuning guide matches wood spine to the bow's weight for a longbow too.[31]

So start from the weaker reading, and let your arrows have the final say:

  1. Start from the chart for your bow type. For a longbow not cut to center, that is 3Rivers' longbow / self bow column. For a center-shot longbow, use the recurve column.[2] Easton's current longbow column is the outlier: check any arrow it suggests against a test shaft first.[4]
  2. Buy two or three test shafts, or a test kit, before a dozen. Confirm the spine before you cut and fletch a full dozen.[24][32]
  3. Bare-shaft or paper tune. Shoot unfletched shafts beside fletched ones, or through paper, and let the arrow show you whether it is weak or stiff.[25] Start about 1 in (2.5 cm) long and cut ¼ in (6 mm) at a time while you bare-shaft tune.[20]

More detail: how spine is measured, and why wood and carbon numbers don't convert

Spine numbers come from two different tests. For carbon and aluminum, the shaft rests on supports 28 in (711 mm) apart and a 1.94 lb (880 g) weight hangs from the middle.[1] The spine number is the deflection in inches times 1000: a shaft that bends 0.500 in is a 500, and an Easton 1716 aluminum shaft bends 0.882 in.[33] A lower number means a stiffer shaft.

The AMO wood test uses supports 26 in (660 mm) apart and a 2 lb (907 g) weight.[1] Wood spine is quoted in pounds, such as 40-45#, and a higher number means a stiffer shaft, the opposite way to carbon numbers.[2]

Because the span and the weight both differ, the two scales convert only roughly. One spine calculator converts with a factor of 0.825,[1] and we found no arrow maker's table that converts wood pounds to carbon spine, so treat any conversion as approximate.

Safety First

Arrow length

Arrow length (measured from the bottom of the nock groove to the end of the shaft) should be a bit longer than your draw length so the arrow extends beyond the bow at full draw.

Measure at full draw

The safest way is to have someone mark an arrow at full draw. Easton marks target arrows about 1 inch in front of the most forward point where the arrow touches the rest.[3] Adding 1-2 inches to your draw length is a common starting estimate in community guides, not a maker's rule.[34]

Example lengths

  • 26" draw: ~28" arrows
  • 28" draw: ~29-30" arrows
  • 30" draw: ~31-32" arrows
Draw Length Measurement
Draw length Arrow length Arrow length: nock groove to end of shaft, point not included
Safety warning

An arrow that is too short for your draw can fall off the rest or be drawn inside the bow, which is dangerous. When in doubt, go slightly longer.

Advanced

Tuning with length

Arrow length affects dynamic spine: longer arrows flex more, shorter arrows flex less. Some experienced archers fine-tune by adjusting length.

Our recommendation: Buy arrows in the correct spine and length from the start. If you don't own a high-speed arrow saw, have a pro shop or your retailer cut your arrows. Cut carbon only with a high-speed cut-off saw, because other saws can damage the shaft.[4][35] Expect a small fee, about $1 per arrow at the shops we checked.[36][37]

Weight Matters

Point weight and total arrow weight

Point weight refers to the weight of the arrow's tip (measured in grains). Total arrow weight is everything combined: shaft, nock, fletching, insert, and point.

Archers often talk about grains per pound (GPP), the total arrow weight in grains divided by the bow's draw weight in pounds, as a guideline for arrow safety and performance.

Grains Per Pound (GPP) Scale
3 5 8 10 13 8 GPP
  • Under 5 GPP: too light. Below the IBO minimum[15] and bow makers' warranty minimums.[38][39]
  • 5 to 8 GPP: meets the 5 GPP minimum. Check your bow maker's minimum, which can be higher.
  • 8 GPP and up: also meets the stricter minimum at least one traditional bowyer sets for its warranty.[40]

The marker shows 8 GPP: a 240 grain arrow from a 30 lb bow.

5 GPP is the floor

The IBO rules set this floor,[15] and bow makers including Hoyt and Mathews write it into their warranties.[38][39] At least one traditional bowyer asks for 8.[40] Use whichever is higher, your bow maker's minimum or 5 GPP.

Above the floor

There is no single standard above the floor. One traditional bowyer recommends 9-11 GPP for its bows.[40] IBO's traditional class requires 10 grains per pound at 28" and no less than 450 grains, but that is a competition rule, not a safety limit.[41]

Hunting rules

Hunting rules set minimum bow weights, not GPP ranges;[42] see the hunting law examples. For hunting arrows, aim for 10-15% FOC.[43]

How point weight changes spine

Heavier points make an arrow act "softer" because more mass up front causes more flex on release. Easton's chart has a rule for it:

Rule of thumb

For every 25 grains of point weight over 100, add 3 lb to your bow weight before you read the chart; for every 25 grains under 100, subtract 3 lb.[4] That is less than one weight row on Easton's 2026 target chart, where rows are 4-6 lb wide.

Example: a 30 lb bow

For a 30 lb recurve, the IBO floor of 5 GPP is 150 grains.[15] If your bowyer asks for 8 GPP, it is 240 grains.[40] Use whichever is higher.

  • Work out your total: shaft length × the shaft's grains per inch, plus point, insert, nock and fletching.
  • Check it: divide by your actual draw weight and make sure you are at or above your floor.
Feathers vs Vanes

Fletching

Fletching (feathers or plastic vanes) makes the arrow spin and steadies it in flight.

Which to choose depends mostly on whether you shoot off the shelf or from a raised rest.

Fletching Comparison
Feathers Natural turkey feather Best for shelf shooters Vanes Plastic (TPU) Waterproof & durable

Off the shelf: feathers

An arrow shot off the shelf brushes the bow with its fletching, so traditional archers mostly shoot feathers.[44] Felt, leather and hair shelf rests are made for them.[45] Feathers are lighter and more flexible than vanes, and give more drag and spin.[44]

Sizes vary by maker and arrow diameter; check the maker's chart.

Raised rest: vanes work too

An elevated rest, such as a rest-and-plunger or a stick-on rest, gives the arrow more clearance, so vanes are an option.[44] Stick-on rests with an arm take either.[45] Vanes are the more durable of the two.[44]

Sizes vary by maker and arrow diameter; check the maker's vane chart.[46]

Three or four? Most arrows carry three feathers or vanes. Some archers use four to steady large broadheads, or so that each fletch can sit lower.[44]

Finding your arrows

Whether you choose feathers or vanes, bright colors on fletching and wraps make arrows easier to find[47], and lighted nocks let you follow an arrow in flight.[48]

High-vis colors that work

Fluorescent orange or green, bright red and pink stand out against leaves and brush.[47] White and bright yellow show up on most ground, while dark colors are easy to lose in foliage.[49]

Buying parts that work together

What fits what

A finished arrow is a shaft plus a few small parts: a nock at the back, a point at the front (sometimes held by an insert or outsert), and fletching. Every part has to fit the exact shaft you own, and the nock also has to fit your bowstring.

Start with the shaft's inside diameter. Press-fit nocks plug straight into it, and not all shafts have the same inside diameter, so know exactly which shaft you shoot before you buy nocks.[50]

Press-fit nock codes by shaft inside diameter[50]
Shaft inside diameter Nock codes that fit Size class
.166 in (4.2 mm) G, F Micro (4 mm class)
.204 in (5.2 mm) X, A Small (5 mm class)
.234 in (5.9 mm) H, H.E. Easton 6 mm (Sonic)
.244 in (6.2 mm) S (Super Nock) Standard (Easton 6.5 mm)
.246 in (6.2 mm) GT Standard (Gold Tip)

Buy the nock your shaft's maker sells for it: every arrow maker makes nocks to fit its own arrows.[50]

More detail: nock letters, and the .244 and .246 sizes

Easton uses the letters as size names too: S nocks for standard shafts, X for small shafts and N for micro shafts.[51]

The .244 and .246 sizes are only two thousandths of an inch apart, and at least one fit chart files .245 and .246 shafts under one standard size.[51]

Four ways a nock attaches

Press-fit nocks

They push into the shaft's inside diameter with no glue, and you can turn them to line up your fletching for clearance.[50] Buy them by inside diameter and shaft maker.

Pin nocks and pin bushings

A pin bushing goes in the shaft and the nock clips onto the pin. Any nock labelled "pin" fits any pin bushing, because pins are one standard size.[50] Pin nocks suit target and 3D, and standard nocks suit hunting. The bushing adds weight at the back, which can change dynamic spine.[51]

Uni-bushings

Some archers fit aluminum Uni-bushings to protect the shaft ends from other arrows. Then you need press-fit nocks made for the bushing, not for the shaft.[50]

Conventional (swage) nocks

These are for aluminum arrows with a cone-shaped back end, called the swage.[50] You press them on by hand, or lock them with a glue that is not a cyanoacrylate (superglue).

Points, inserts and outserts

Glue-in points go straight into the shaft and are common on thin target shafts. They are usually set with hot-melt glue rather than quick-set glue, so you can heat them and pull them out to make changes.[52] Some break off in sections so you can trim the weight, for example from 140 down to 90 grains (9.1 to 5.8 g).[52]

Screw-in points thread into an insert glued inside the shaft. The usual thread is 8-32, and 75-150 grains are the most popular weights.[52] Screw-in points suit recreational archers, bowhunters and some 3-D archers, because you can swap field points for broadheads of the same weight.[52]

Match the point to the outside diameter of your shaft or insert, so it flows smoothly into the shaft.[52]

Not every insert is 8-32: some thin shafts take their own thread and points.[53] Check the thread before you order points or broadheads.

Whatever holds the point adds weight at the front: a standard aluminum insert might weigh about 16 grains (1.0 g), while a brass insert can weigh 100 grains (6.5 g).[54]

Front weight changes the spine you need. On Easton's chart, for example, a 29-inch arrow from a 62 lb bow needs a 340 spine with a 100-grain broadhead, but a 300 spine if the point is 50 grains heavier.[54]

More detail: thin-shaft inserts, outserts and how charts count point weight

Easton's 4 mm Deep Six HIT insert (20 grains, 1.3 g) takes Deep Six points, and Easton's Deep Six field points fit Deep Six inserts only.[53]

Outserts and half-outs are another way to hold a point on very thin hunting shafts. Easton's 4 mm half-outs weigh 50 grains (aluminum 8-32), 55 grains (titanium, takes 8-32 thread 5/16 in field points) and 95 grains (steel).[53] Easton's HIT inserts are made for its own shafts: the 5 mm HIT weighs 16 grains, and a Match Grade HIT collar adds 13-21 grains.[53]

Gold Tip counts point, insert, collar and any added weight together as "point weight" when you use its chart.[20]

Wood shafts

Wood shafts come in a few standard diameters, and each diameter covers its own band of spines. Here is what one supplier lists for Port Orford cedar shafts.[55]

Port Orford cedar shafts: spine ranges sold in each diameter (one supplier's listing; others vary)
Shaft diameter Spine ranges sold
5/16 in (7.9 mm) 30-35, 35-40 and 40-45 lb
11/32 in (8.7 mm) 40-45 lb up to 65-70 lb, in 5 lb steps
23/64 in (9.1 mm) 50-55 lb up to 75-80 lb, in 5 lb steps

So once you know your spine, you also know roughly which diameter you are buying, and your nocks and points must match that diameter. These cedar shafts are factory spined to within 5 lb.[55]

Glue-on points need a 5-degree point taper cut on the shaft end. The 5-degree taper is an industry standard, so glue-on points fit any shaft cut with it.[56]

A taper tool cuts both nock and point tapers in each shaft diameter,[57] and traditional glue-on nocks are sized by shaft diameter too.[58]

Nock fit on the string

The nock has to fit your string as well as your shaft. When you nock the arrow, you want a small click: not too tight, not too loose.[51] A tap on the string should knock the arrow off.[59]

The arrow should easily hold its own weight hanging from the string, and nock tension matters most on bows of 30 lb (13.6 kg) and under.[3]

Many nocks come in a small and a large groove. Small-groove nocks are for skinnier strings, like those on low-poundage recurves; large-groove nocks are for compound bows and recurves with thicker strings.[50]

More detail: groove and throat, and Beiter nock sizes

Two parts of the nock matter. The groove is the tighter section that holds the string; the throat is the section that touches the string during the shot.[51]

Beiter numbers its sizes instead. The #1 is for thinner serving (generally 12 to 16 strands) and the #2 for larger serving (generally 14 to 18 strands), depending on material thickness.[51] Standard Beiter nocks are asymmetrical, for finger shooters; Beiter Hunter nocks are symmetrical, for compounds with a D-loop and release aid.[51]

Why fit matters

A bad nock fit can cause dry-fire situations, string torque, serving damage and lost arrows.[51]

Front of center (FOC)

FOC describes the percentage of the arrow's total weight that sits in its front half.[43] Your choice of point, insert, nock and fletching all move it.

More detail: the FOC formula, and a worked example
Easton's formula (AMO standard)

FOC % = 100 × (A − L/2) ÷ L

L is the correct arrow length: bottom of the nock groove to the end of the shaft. A is the distance from the bottom of the nock groove to the balance point of the finished arrow, with point (and insert), nock and fletching fitted.[3]

To find A, balance the finished arrow on a knife edge with the point you will shoot mounted.[60] For example, a 29-inch Easton Axis 5mm 340 with a 100-grain point comes to about 415 grains (26.9 g) and 12% FOC, inside Easton's range.[54]

Some people work out FOC with total arrow length instead of shaft length. The answer comes out different for the same arrow, so only compare FOC figures worked out the same way.[60]

Easton's recommended FOC ranges (AMO formula)[43]
Use FOC
Target, indoors 7-15%
Target, outdoors (0-90 m) 10-15%
Hunting 10-15%

On Easton shafts, the recommended point puts the FOC in range on its own.[43]

More is not always better: too much FOC lowers an arrow's dynamic spine, which can cause tuning problems, and over 20% it makes finger-release consistency much more critical.[43]

More detail: FOC bands from bowhunting research

Dr. Ed Ashby's bowhunting research sorts arrows into four bands (AMO formula): normal FOC is 12% and less, high FOC over 12% up through 18%, extreme FOC (EFOC) 19-30%, and ultra-EFOC above 30%. In his study, the first measurable tissue-penetration gains from FOC appeared at the EFOC level, 19%.[61] These are his study's definitions, not an industry standard.

The rule that saves the most money

Buy nocks, inserts and points made for your exact shaft model and size. Easton, for example, sells separate nock, insert and point families for each of its shaft diameters.[62]

When in doubt, give the shop the shaft's maker, model and spine, and let them pick the parts.

Different Goals, Different Setups

Target vs. hunting arrows

The best arrow for punching paper isn't always the best one for hunting or stump shooting.

Target shooting

Accuracy and consistency are king

Arrow weight

Lighter arrows for a flatter trajectory and faster flight, never below 5 GPP or your bow maker's minimum

Spine

Finely tuned, often slightly weaker for finger release

Fletching

Low-profile vanes sized for your arrow diameter (check the maker's vane chart)

Point weight

100 grains is the basis of Easton's charts;[4] screw-in points of 75-150 grains are the most popular[52]

30# target setup example

675-600 spine carbon (Easton's 2026 chart for 30 lb at 30" with a 100gr point),[4] 30" length, 100gr point, vanes on a raised rest. Total weight depends on the shaft; at 30 lb, stay at or above 150 grains (5 GPP), or your bow maker's minimum if that is higher.[15]

Hunting and stump shooting

Penetration, durability, and visibility

Arrow weight

Heavier arrows for penetration and quiet flight

Spine

Robust shafts that survive impacts

Fletching

Feathers or vanes; some archers use four fletches to stabilize large broadheads[44]

Point weight

A standard broadhead weighs 100 grains, with 125 and 150 common; heavier points need a stiffer shaft[54]

30# stump setup example

500 spine carbon (31" long), 125gr blunt/judo point, bright feathers. Easton's 2026 chart gives 575-500 for this setup once you add 3 lb for the 125gr point, and 3Rivers' traditional carbon chart gives 500.[2][4] A 320 grain arrow would be 10.7 GPP. Durable and easy to find.

Flu-flu arrows

Exaggerated fletching that slows the arrow down quickly. Great for aerial shots or preventing lost arrows.

Blunts and judos

Specialty points for stump shooting. Blunts won't bury deep; judo points have spring arms to grab grass and stay visible.

Finding a missed arrow

Use bright fletching, or reflective wraps that glow in a flashlight beam.[63] After a miss, leave your bow where you stood, walk past the target and look back toward the bow: the arrow should lie somewhere between you and the target.[64]

Bow fit

Know your bow

Arrows are only half of the fit. Before you buy them, make sure the bow itself suits you: its weight, its length, how its limbs attach, its string and its brace height.

Starting draw weight

Start lighter than you think. World Archery's coaching manual gives these maximum weights for novices:[7]

World Archery novice bow weights (maximum)
Archer Bow weight (max.)
Children 6 to 8Up to 10 lb (4.5 kg)
Children 8 to 12Up to 12 lb (5.4 kg)
Girls 12 to 1412-16 lb (5.4-7.3 kg)
Boys 12 to 1614-18 lb (6.4-8.2 kg)
Girls 15 to 1715-18 lb (6.8-8.2 kg)
Boys 15 to 1716-20 lb (7.3-9.1 kg)
Women16-20 lb (7.3-9.1 kg)
Men18-22 lb (8.2-10.0 kg)

Move up slowly. The same manual says never to raise a novice's bow weight by more than 2 lb (0.9 kg) at a time.[7]

A quick check: if you can't hold the string back for even a few seconds without shaking, the bow is too heavy,[65] and a bow heavier than you can handle risks injury.[66]

More detail: a strength test, and what elite archers pull

The same manual also gives a strength test. A novice should manage its 10-second draw-and-hold exercise 8 times without losing form, and once they can do it 10 to 12 times, 2 lb more is worth considering.[7]

For scale, the recurve men at the 2018 World Cup Final averaged around 48-50 lb (22-23 kg).[66] That is an elite figure, not a starting point.

Coming from a compound? A 70 lb compound with 75% let-off holds about 18 lb at full draw, while a 50 lb recurve holds the full 50 lb.[65] Don't pick a recurve weight from your compound's label.

Bow length and draw length

Bow length is measured tip to tip on the unstrung bow, with the tape following the limbs.[9] It has to suit your draw. If a short bow is chosen for a long draw, the limbs bend more than they were designed for and may even break.[7]

On a takedown recurve, bow length is riser plus limbs, and each step up in riser or limb size adds 2 in (5 cm).[9]

Which length do you need? World Archery's coaching manual gives a minimum bow length for each draw length, for novices on a recurve.[7] It also notes that 66 in and 68 in are the most common recurve lengths.[7]

World Archery: novice draw length and bow length (minimums)
Draw length Bow length
Up to 18 in (46 cm)48 in (122 cm)
18-20½ in (46-52 cm)52 in (132 cm) or longer

Uukha, an ILF limb maker, gives its own guide for its target recurves: 66 in for a draw of 27 in AMO or less, 68 in for 28 in, 70 in for 29-30 in, and 72 in for 31 in or more.[10] At a 29 in draw that is one size longer than World Archery's minimum. That is Uukha's preference, and the two don't clash, because World Archery's figures are minimums.

How the limbs attach

A takedown recurve comes apart at the riser, and the way its limbs attach decides what you can mix.

ILF

Mixes across brands

The International Limb Fitting is a uniform attachment that lets limbs from many makers fit risers from many makers.[67]

Hoyt Formula

Formula only

It looks like ILF but does not fit it: the distance between the limb end and the detent is longer on Formula limbs.[67] Hoyt sells its ILF-compatible risers and limbs under the Grand Prix name.[67]

Proprietary

One maker

Some takedowns use a fitting of their own. Only Galaxy Sage limbs work with Galaxy Sage risers, for example.[67] For these bows, follow the maker's compatibility list.[67]

Buying your first takedown? Spend more on the riser than on the limbs: most people soon go up in poundage and buy limbs again.[16] That makes a cross-brand fitting worth having.

Strings

String length follows bow length. If no string length is marked on the bow, use a string 3 in (7.6 cm) shorter than the bow: a 68 in bow takes a 65 in string.[5][9]

Low-stretch HMPE strings (Dyneema and Fast Flight) are not for every bow. If your bow was made before 1990, use only Dacron.[59] At least one bowyer warns that at draws of 29 in or more, a high-performance string can significantly increase the chance of limb-tip damage.[40] Whatever the age of your bow, check that its maker rates it for HMPE.

More detail: string length, stretch, twists and strand count

Go by that AMO length, not a tape measure. A 68 in AMO string actually measures 64 to 65¼ in (163-166 cm), depending on the bow and the string material.[59]

Twists fine-tune the fit: adding them raises the brace height, and removing them lowers it. Hoyt does not recommend fewer than 10 twists in a string.[9]

Dacron stretches more than modern materials. Untensioned, a Dacron string can measure up to 1 in shorter than under 100 lb (45.4 kg) of tension, while BCY DF97 or 8125 may vary by only ¼ in.[59]

Strand count by draw weight, recurve and longbow strings
Draw weight Dacron Dyneema / Fast Flight
10-30 lb (4.5-13.6 kg)10-12 strands12-14 strands
30-40 lb (13.6-18.1 kg)14 strands16 strands
Over 40 lb (18.1 kg)16 strands18-20 strands

A string change also changes your arrows: the 3Rivers charts count a Fast Flight string as 5 lb more bow.[2]

Brace height

Brace height, also called fistmele, is the perpendicular distance from the string to the pivot point of the grip.[9]

It matters in both directions. Too low, and the bow is unstable and the string will most likely strike your wrist; too high, and the power stroke gets shorter.[7]

Start from your bow maker's figure.[7] If your maker gives none, World Archery's generic chart is a fallback.

More detail: brace height by bow length
Brace height by bow length: World Archery's generic chart and Uukha's figures (both published in metric)
Bow length World Archery range World Archery typical Uukha (±10 mm)
64 in19.7-22.9 cm (7.8-9.0 in)21.5 cm (8.5 in)205 mm (8.1 in)
66 in20.3-23.5 cm (8.0-9.3 in)22 cm (8.7 in)211 mm (8.3 in)
68 in21-24.1 cm (8.3-9.5 in)22.5 cm (8.9 in)218 mm (8.6 in)
70 in21.6-24.8 cm (8.5-9.8 in)23 cm (9.1 in)225 mm (8.9 in)

To find the best height, shoot a few arrows at the suggested starting height, then unstring the bow, add 3-4 twists and shoot again, until the bow feels smoothest and quietest.[3]

Compounds are different again. Their brace height is set by the maker, and changing it changes the bow's draw weight and draw length.[3]

Crossbows

Crossbow bolts: buy what your maker specifies

A crossbow bolt is a short arrow, typically 16 to 22 in (40.6 to 55.9 cm) long.[68] It rests in a flight groove on the barrel, where the string pushes on its nock.[69] Manuals often call them arrows.

A crossbow's maker has already chosen the bolt for each model, and the manual lists its weight, diameter, length and nock style.[69][70]

Underweight bolts can cause a dry-fire effect and break the limbs.[69] The wrong nock can let the string shoot over or under the bolt.[69] Some makers also void or limit the warranty if you use other bolts or nocks.[71][72]

The fit finder does not size crossbow bolts

The crossbow's maker sets them. Use your owner's manual and the checklist below.

Five specs to look up in your manual

Length

Usually a minimum, often 20 in (50.8 cm), though some models need 22 in (55.9 cm) and some take 18 in (45.7 cm).[73][74] Match or slightly exceed the rail length: too short risks a dry-fire, and too long hurts stability.[68]

Minimum total weight

Count the finished bolt with its point fitted.[75] A bolt that's too light can't absorb the shot's energy, which creates a dry-fire condition that can damage the crossbow.[71]

Nock type

The nock has to suit the string and trigger. At least one maker's anti-dry-fire trigger works only with its own nock.[71]

Point weight

Check the point weight your bolts were designed around, often 100 grains (6.5 g).[69][72] Heavier broadheads may need shoot-testing,[76] and scope marks may shift with a different bolt or point.[74]

Shaft and vane orientation

Ravin allows only its own bolts.[71] On many crossbows, the odd-colored (cock) vane goes in the flight groove.[69][77] Check your manual for any vane clearance rule.[78]

Where a maker gives two figures, as Barnett's FAQ does, use the higher one.[70] Specs also change by year: TenPoint's Alpha-Nock warranty rule names its 2019 and newer crossbows.[69]

Other maker rules: TenPoint designed its bolts for ideal FOC (front of center) with a 100-grain point; 125- or 150-grain (8.1 or 9.7 g) broadheads may need shoot-testing.[76] Killer Instinct's Rush 400 scope marks assume a 400-grain (25.9 g) bolt.[74] Ravin's bolts have a glued rear metal insert, and shafts without one are more likely to fracture.[71] Mission wants the vanes to start at least 1.35 in (3.4 cm) from inside the nock.[78] Excalibur's bolts have no cock vane, because their flat insert can face any way, and its illuminated Diablo is 265 grains (17.2 g) bare, the standard one 250 (16.2 g).[75]

Nock types

Half-moon (moon)

A crescent-shaped nock that lines up with the string.[79] Put the odd-colored vane in the flight groove and check that the curve of the nock matches the curve of the string.[74]

Flat (flatback)

A flat base that is easy to align.[68] Some crossbows use a flat threaded insert instead of a nock,[75] and some makers forbid flat nocks.[69][71]

Maker-specific nocks

TenPoint's Alpha-Nock has a deep groove and large radius base that hold the string on narrow crossbows to prevent shoot-over or shoot-under misfires.[69] Ravin's Clip-on nock takes about 5 lb (2.3 kg) of force to engage, with an audible click, and its opening sits perpendicular to the white cock vane.[71]

Capture, omni and lighted nocks

Capture and omni nocks need specific crossbows,[68] and TenPoint bans capture and moon nocks on its own.[69] A lighted nock must be on your maker's approved list,[69] and it adds weight: about 15 grains on one maker's bolts.[75]

The wrong nock

The wrong nock type can cause poor accuracy, dry-firing or equipment damage.[68]

Safety rules

  • Never dry-fire. After one, have a dealer or the factory inspect the crossbow before you cock or shoot it again.[69] A dry-fire can also void the warranty.[78]
  • Never uncock by dry-firing. The crossbow needs the bolt's weight to absorb its energy, so shoot an old bolt into a safe target instead.[69][77]
  • Fingers below the rail. Keep your thumb and fingers below the flight deck and away from the cables.[69] Most injuries happen while target shooting with the crossbow on a rest.[75]
  • Seat the bolt fully. Slide it all the way back under the hold-down spring until it sits firmly against the string.[75]
  • Always fit a point. Never shoot a bolt without a field point or broadhead.[74][78]
  • Inspect every bolt before every shot. Feel along the shaft and nock, flex the bolt 0.5 to 1 in (1.3 to 2.5 cm) listening for cracks, and twist it: a shaft that twists easily is damaged.[74] A cracked carbon shaft can shatter and throw fragments, and a damaged nock can cause a dry-fire.[69][71]

Your crossbow bolt checklist

  1. Maker, model and year of your crossbow, and its owner's manual.
  2. Length: the manual's figure, and the length of the bolts that came with the crossbow.
  3. Minimum total weight, counted with the point fitted, and the bolt weight your scope is set up for.
  4. Nock type by name (for example Alpha-Nock HPX, Ravin Clip-on, half-moon or flat), including any lighted nock your maker approves.
  5. Point weight the bolts were designed around, plus any broadhead width your hunting rules set.
  6. Shaft: whether the warranty requires the maker's own bolts, and any vane orientation or fletching clearance rule.
  7. When unsure, reorder the bolt that came with your crossbow.[82]
Before you shoot, before you buy

Safety and a buying checklist

Most arrow safety comes down to one idea: the arrow has to be heavy enough, long enough and sound enough for the bow it leaves, whichever of the six bow types you shoot.

Minimum arrow weight

Arrows must weigh at least 5 grains per pound of the bow's maximum shooting weight, its peak weight as set up.[15] Below that, bow makers void the warranty or tell you not to shoot the arrow.[13][38][39] At least one traditional bowyer asks for 8.[40] Use whichever floor is higher. Point weight and total arrow weight works through an example.

Never dry-fire

Never draw and release your bow without an arrow on the string. It can damage the bow and hurt you or people nearby.[13][14] If it happens, don't shoot the bow again until a pro shop has inspected it.[8][38] Bow makers don't cover dry-fire damage under warranty.[14][83]

Check your nocks too. Throw away any nock with a crack or damage of any kind: a bad nock can cause a dry-fire.[51]

No wood arrows from a compound

Don't shoot wooden or fiberglass arrows from a compound bow: they "may cause serious injury".[83][84]

The wood spine charts we checked cover only recurves and longbows.[19]

Long enough for your draw

Never shoot an arrow that is too short for your draw.[85] Arrow length shows how to measure it.

Hunting law: examples, not advice

Copy this into your order: a shop can only fit what you tell it.

  1. Bow type: Olympic recurve, barebow, traditional recurve, longbow, horse bow or compound. For a longbow, say whether it is center-shot: the 3Rivers charts read center-shot longbows like recurves.[2]
  2. Draw weight, marked and actual: the number on the limbs and what the bow really pulls at your draw length. Non-compound bows are marked at a 28 in (71.1 cm) draw, and the 3Rivers charts count roughly 2-3 lb for every inch either side.[2][5]
  3. Draw length.
  4. Cut length, and how it was measured: Easton measures from the bottom of the nock groove to the end of the shaft, Gold Tip from the nock throat to the end of the insert.[18][20]
  5. Spine, as a range, and which chart it came from.
  6. Point weight, counting any insert, half-out or collar, and the point type: glue-in, 8-32 screw-in, or glue-on for a 5-degree taper.
  7. Shaft inside diameter and nock size: the shaft's maker and model, its inside diameter, the nock model (or pin nock and pin bushing), and the groove size that clicks onto your string.
  8. Fletching: feathers if you shoot off the shelf, vanes only with a raised rest; three or four fletches.[44]
  9. Total arrow weight, checked against your floor: 5 grains per pound or your bow maker's figure, whichever is higher.
  10. Buy a test kit or three shafts first. Charts disagree, and a few test shafts cost less than a second dozen.

Where to buy

Start with a local archery pro shop if you have one. Staff can weigh your bow, check your draw length, cut shafts and fit the parts, and some keep test shafts. In the US, the ATA's store locator finds archery shops by ZIP code. Elsewhere, a local archery club can point you to one.

Buying online? These independent archery specialists in the US sell shafts and arrow-building parts.
