Draw Length Formula:
| From: | To: |
Draw length is the distance from the nocking point on the string to the pivot point of the bow grip plus 1.75 inches. It's a crucial measurement in archery that affects accuracy, comfort, and shooting form.
The calculator uses the standard formula:
Where:
Explanation: This formula provides a reliable estimate of proper draw length based on an archer's wingspan measurement.
Details: Correct draw length is essential for proper shooting form, accuracy, and preventing injury. An improper draw length can lead to inconsistent shots, muscle strain, and decreased performance.
Tips: Measure your wingspan accurately by standing with arms outstretched and measuring from fingertip to fingertip. Enter the measurement in inches. The value must be greater than 0.
Q1: Why is wingspan divided by 2.5?
A: This ratio has been established through archery research as providing the most accurate correlation between wingspan and optimal draw length for most archers.
Q2: Is this calculation accurate for all archers?
A: While this formula works well for most people, individual variations in body proportions may require professional fitting for optimal results.
Q3: How should I measure my wingspan 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 tip of your middle finger on the other hand.
Q4: Can draw length change over time?
A: Yes, draw length can change with changes in flexibility, strength, or shooting form. It's good to re-evaluate periodically.
Q5: Should beginners use this calculation?
A: Yes, this provides a good starting point, but working with a qualified archery coach for final adjustment is recommended.
