# Arrow Cut Length Calculator

> Calculate the right arrow cut length from draw length, rest position, and point type. Get a safe minimum length for broadheads and field points.

An arrow that is too short can pull a broadhead back onto the rest or your hand. An arrow that is too long adds weight and weakens dynamic spine. Find a safe, practical cut length for your bow before you cut a dozen shafts.

## 🎯 Arrow Cut Length Calculator

The draw length your bow is set to

Positive = in front of the pivot. Most rests: 0 to 1.5 in

Sets clearance in front of the rest

Optional, e.g. to weaken spine slightly

Recommended Cut Length

**How this is calculated:**

Nock throat to grip pivot = Draw length − 1.75 in

Cut length = (Draw length − 1.75) + Rest position + Clearance + Extra

Length is measured from the nock throat (where the string sits) to the end of the carbon, not including the point or insert lip.

## 📏 The Most Accurate Method: Measure at Full Draw

1. Take an uncut arrow or a long test shaft and mark it with a fine pen.
2. Have a helper watch while you come to full draw with the uncut arrow on the rest. Never dry-fire.
3. The helper marks the shaft where it crosses the front of the rest launcher.
4. Add your clearance: about 1/2 in for field points, 3/4 in for mechanicals, and at least 1 in for fixed blades.
5. Measure from the nock throat to the new mark. That is your cut length.

Use the calculator above to sanity-check the measurement. If the two disagree by more than half an inch, measure again.

## 📊 Typical Cut Lengths by Draw Length

Compound bows with the rest launcher about 3/4 in in front of the pivot.

| Draw Length | Field Points | Mechanical Heads | Fixed Blades |
| --- | --- | --- | --- |
| 26 in | 25.50 in | 25.75 in | 26.00 in |
| 27 in | 26.50 in | 26.75 in | 27.00 in |
| 28 in | 27.50 in | 27.75 in | 28.00 in |
| 29 in | 28.50 in | 28.75 in | 29.00 in |
| 30 in | 29.50 in | 29.75 in | 30.00 in |

### How length affects spine and FOC

Every extra inch of shaft makes an arrow act weaker in spine and moves the balance point back, lowering FOC. After choosing a length, confirm spine with the [arrow spine calculator](https://archeryprotools.com/calculators/arrow-spine-calculator) and balance with the [FOC calculator](https://archeryprotools.com/foc-calculator).

## ❓ Frequently Asked Questions

**How long should my arrows be for a 29-inch draw?**

With a typical compound rest, about 28.5 in for field points and around 29 in for fixed-blade broadheads, measured nock throat to end of carbon.

**Is it safe to shoot arrows shorter than my draw length?**

Only if the point stays clearly in front of the rest at full draw. A broadhead that comes back onto the rest can cut you or knock the arrow off the rest.

**Should arrow length match draw length exactly?**

Not necessarily. Draw length is measured to the grip pivot plus 1.75 in. Where your rest sits and the point you shoot both change the right length.

**Does cutting arrows shorter make them stiffer?**

Yes. A shorter shaft behaves stiffer in dynamic spine. Cutting about 1 in shorter acts roughly like going one spine group stiffer.
