Draw Length Formula:
From: | To: |
The Recurve Bow Size Calculator estimates the appropriate draw length for a recurve bow based on the archer's arm span. Proper draw length is essential for accurate shooting and preventing injury.
The calculator uses the standard formula:
Where:
Explanation: This formula provides a reliable estimate of draw length, which is crucial for selecting the correct bow size and ensuring proper shooting form.
Details: Correct draw length ensures optimal arrow speed, accuracy, and shooting comfort while preventing strain injuries and poor shooting technique.
Tips: Measure arm span accurately from fingertip to fingertip with arms fully extended parallel to the ground. Enter the measurement in inches for precise calculation.
Q1: Why is draw length important for recurve bows?
A: Proper draw length ensures consistent anchor points, optimal power transfer, and prevents over-drawing or under-drawing which can affect accuracy and cause injury.
Q2: What is a typical draw length range?
A: Most adult archers have draw lengths between 24-30 inches, but this can vary based on individual physique and arm span.
Q3: How do I measure arm span accurately?
A: Stand against a wall with arms fully extended sideways at shoulder height. Have someone measure from the tip of your middle finger on one hand to the other.
Q4: Can draw length change over time?
A: Draw length is generally stable for adults but may change slightly with improved form, flexibility, or physical changes.
Q5: Should I round my draw length measurement?
A: Most bows are available in half-inch increments, so rounding to the nearest half-inch is typically sufficient for practical purposes.
