Estimate your ideal draw length based on your arm span. Essential for bow setup, consistent form, and choosing the right equipment size. A correct draw length is the foundation of a repeatable anchor point and long-term accuracy for both compound and recurve archers.
Measure your arm span (fingertip to fingertip) with your arms outstretched like a 'T', or your full wingspan, and enter that measurement in inches. Stand naturally against a wall and have someone read the distance between your middle fingertips — do not over-reach or hunch, since an exaggerated stance inflates the result.
This estimator uses the widely taught span-to-draw rule: draw length equals your measurement divided by 2.5. A 70-inch arm span therefore yields a 28-inch draw length. The tool also suggests a starting arrow length of draw length plus 1.75 inches, giving roughly 29.75 inches in that example, so you leave a safe margin past the rest at full draw.
A proper draw length is critical for consistent anchor points and back tension; even half an inch of error changes your anchor, peep alignment, and the bow's measured speed. Treat the estimate as a starting point and visit a professional pro shop to fine-tune the final setting on a draw board before you cut shafts.
Incorrect draw length leads to poor form, inconsistent anchor points, and shoulder strain. It also affects the bow's efficiency and the arrow's speed.
Generally, no, but the way they are measured differs slightly. Compound bows have a 'wall' (stop), while recurve draw length is determined by your anchor point.
Stand against a wall, stretch your arms out wide, and have someone measure from the tip of one middle finger to the other. Don't over-stretch or hunch your shoulders.
