How to Measure Recurve Bow Length

Quick answer: recurve bow length is usually listed as AMO bow length. It is measured along the unstrung bow’s curve from string groove to string groove, not straight tip to tip. Your draw length and use case affect which bow length feels right, so manufacturer sizing guidance matters.

A recurve bow measured along its length with a tape.
AMO length follows the string groove from tip to tip.

What recurve bow length means

AMO length is a standardized bow length reference. It helps match bow length with string length and archer fit. Beginners sometimes get confused because recurves are curved and do not measure cleanly in a straight line.

For a recurve, the printed size is the size you compare against when you are choosing a bow, not a straight ruler measurement across the limbs.

Recurve bow length follows the curve of the unstrung bow. A straight tip-to-tip measurement can give the wrong number.

How to measure recurve bow length

  1. Unstring the bow safely.
  2. Lay the bow on a clean surface.
  3. Use a flexible tape.
  4. Measure along the belly or curve from string groove to string groove.
  5. Compare the result with the manufacturer or AMO marking if present.

If you are not sure about the measurement, compare the result with the bow’s label or ask a shop to confirm it.

Recurve bow length vs string length

Recurve string length is usually shorter than AMO bow length. Do not assume a straight-line tip-to-tip measurement gives string size. If you want to check string length as well, the live string guide can help:

That guide is useful for string fit, but it is a different measurement from bow length.

Recurve bow length and draw length

Longer draw lengths often pair better with longer bows. A bow that is too short can feel cramped, stack more, and create a sharper string angle at full draw. If you are comparing fit, use the draw-length guide and calculator alongside bow length:

Common recurve bow lengths

Bow length General use
62–64 inches Shorter recurves, smaller archers, or some hunting-style setups
66 inches Common beginner and target range for many archers
68 inches Common target recurve size
70 inches Taller archers or longer draw lengths
72 inches Very long draw or specific target setups

These are general orientation points, not a universal rule.

Beginner sizing note

Beginners should avoid choosing a bow only by height. Draw length and intended use matter more than a simple height chart. A club or shop fitting can save a lot of guesswork, and youth archers often need different guidance from adult archers.

Mistakes to avoid

  • Measuring straight tip to tip
  • Confusing bow length with string length
  • Ignoring draw length
  • Copying another archer’s bow size
  • Buying too short for target shooting
  • Using an old string of unknown size

Frequently asked questions

How is recurve bow length measured?

Measure the unstrung bow along the curve from string groove to string groove.

Is recurve bow length measured tip to tip?

No. A straight tip-to-tip measurement can give the wrong answer.

What does AMO bow length mean?

AMO is a standardized bow length reference used so archers can compare bows and strings consistently.

What size recurve bow should a beginner use?

It depends on draw length and intended use. A shop or club fitting is the safest way to narrow it down.

Is bow length the same as string length?

No. String length is usually shorter than the bow’s AMO length.

Does draw length affect recurve bow size?

Yes. Longer draw lengths often work better with longer bows.

Should I unstring a recurve before measuring it?

Yes. Measure the bow unstrung so the curve is not distorted by tension.
