Draw Length Calculator

Measuring your bow draw length?

Accurately adjusting a compound bows draw length is important for comfortable shooting and accuracy. Determining your draw length requires only a simple measurement and calculation.  The easiest way to do it is to extend both arms to your sides and measure the distance between the tips of your middle fingers. Once you have this measurement, called your wingspan, simply enter it into the Draw Length Calculator below to get your draw length.  Alternately, you can use the formula for calculating bow draw length which is your wingspan divided by 2.5. When you order a bow from Dewclaw Archery, we will adjust your draw length to your measurements so your bow fits you.
