📏 Draw Length Calculator
Measure your wingspan fingertip to fingertip, and we'll calculate your draw length using the industry-standard wingspan ÷ 2.5 method.
How to use this calculator
- Stand against a wall and spread both arms straight out to form a T.
- Have someone measure fingertip to fingertip in inches.
- Enter the measurement — your draw length is wingspan divided by 2.5.
Frequently Asked Questions
How accurate is the wingspan method?
Within about half an inch for most people. A pro-shop measurement with a draw-check bow is the gold standard, but wingspan ÷ 2.5 is the accepted starting point used by nearly every bow manufacturer.
What happens if my draw length is set wrong?
Too long causes string slap, poor back tension and floating anchor points; too short cramps your form and costs speed. Either way accuracy suffers, so it is worth getting right before you buy.
Is draw length the same for compound and recurve?
The measurement method is the same, but compounds are set to a fixed draw length while recurve draw length varies slightly with your anchor and form.
