Draw length is difficult to define. So many things are in play that it can vary greatly between 2 shooters with the same wing span. I go by arrow length. Nock an arrow, draw to your anchor point and have someone mark the arrow at the back of the handle at full draw. The length from the bottom of the nock to the point marked is your draw length...for that bow. Other styles of grips on different bows can cause that length to vary.
