How to Determine Arrow Length
How to Determine Arrow Length
A safe arrow length starts with draw length, then adds enough shaft for the bow, rest or shelf, point clearance, and the way you shoot. A common starting point is draw length plus about 1 to 2 inches.
Quick answer
Starting arrow length = draw length + 1 to 2 inches. That is only a starting estimate. Final arrow length depends on bow type, rest or shelf setup, broadheads or field points, clicker use, and tune. Do not cut arrows so short that the point can pull behind the rest or shelf at full draw.
- If you do not know your draw length, use the Draw Length Calculator first.
- Use the Arrow Length Calculator to add a safe allowance.
- Confirm the fit before you cut shafts.
Use the Arrow Length Calculator
The Arrow Length Calculator estimates arrow length from draw length plus a selected allowance. If you still need draw length, use the Draw Length Calculator first. Once you have a starting length, the Arrow Weight Calculator can help you compare finished arrow mass before you cut shafts.

What arrow length means
Arrow length is usually measured from the throat of the nock to the end of the shaft, not including the point. It is not the same thing as draw length. Cutting an arrow shorter changes stiffness, so spine behavior and tune can change too.
Arrow length is not draw length
Arrow length should leave safe clearance in front of the rest or shelf. Confirm fit before cutting shafts.
That is why a safe cut starts with measurement, then moves to fit, clearance, and tuning instead of treating draw length as the final shaft length.

Basic arrow length formula
Starting arrow length = draw length + 1 to 2 inches. A 1.5-inch allowance is a common middle ground when you want a safe starting point.
| Draw length | Conservative allowance | Starting arrow length |
|---|---|---|
| 26 in | +1.5 in | 27.5 in |
| 27 in | +1.5 in | 28.5 in |
| 28 in | +1.5 in | 29.5 in |
| 29 in | +1.5 in | 30.5 in |
| 30 in | +1.5 in | 31.5 in |
How to measure for arrow length
- Confirm draw length with a calculator or a bow-fit check.
- Draw safely with an uncut or clearly marked arrow if you need a live check.
- Mark the safe clearance in front of the rest or shelf at full draw.
- Add allowance for broadheads, tuning, or beginner safety margin.
- Confirm the measurement before you cut shafts.
If broadheads are part of the setup, leave enough clearance for the longer tip and final tune.
Recurve, compound, and traditional bow notes
- Recurve: many beginners leave arrows a little longer for safety and easier tuning.
- Compound: arrow rest position, broadhead clearance, and manufacturer setup matter.
- Traditional or longbow: shelf clearance and shooting style matter.
- Clicker users: usually need a more precise finished arrow length.
Common mistakes
- Using draw length as the final arrow length.
- Cutting all arrows before test fitting.
- Ignoring broadhead clearance.
- Copying another archer’s arrow length without checking the bow.
- Forgetting that shorter arrows can act stiffer.
Safety note
Arrows that are too short can be dangerous. Confirm fit before cutting, follow bow manufacturer guidance, and ask a qualified shop, coach, or experienced archer if you are unsure.
Frequently asked questions
Short answers for the most common arrow-length questions.
How much longer should arrows be than draw length?
A common starting point is 1 to 2 inches longer than draw length, then you confirm fit before cutting shafts.
Is arrow length the same as draw length?
No. Draw length is a bow fit measurement. Arrow length is the shaft length you choose to fit that draw length, the rest or shelf, and the tune.
Should beginners use longer arrows?
Usually yes. A slightly longer starting arrow gives beginners more margin for safety and test fitting before the final cut.
Does arrow length affect spine?
Yes. Shorter arrows act stiffer, so changing shaft length can change the spine behavior and the tune.
Can arrows be too long?
They can. Excess length can create fit problems, but too short is the bigger safety concern. Start longer, then trim carefully.
Should broadheads change arrow length?
They can. Broadheads often need extra attention to clearance, so confirm the full setup before you cut shafts.
Next steps
Use the Arrow Length Calculator, then confirm the number against the bow, the draw length guide, and the arrows hub before you cut shafts.
Check arrow spine next
After you settle on a safe arrow length, check the shaft maker’s spine chart before you buy or cut a big batch. The right length is only part of the setup.
