Arrow Length - refers to the length of the arrow shaft. Arrow size - refers to the spine (stiffness) of the arrow. The shaft size is always referring to the diameter of the shaft, the wall thickness of the shaft and the distance that the arrow shaft will flex before it bends or breaks.
Draw Weight and Length. Back to Bow Tuning. Most bows draw weight is measured at 28 unless marked otherwise. The amount of force applied to your arrow that is going to make it bend is determined by the draw weight of the bow at your draw length. To measure your draw length, draw the bow and have someone mark the arrow on the back side (the side away from you) of the bow or clip a clothes pin on the shaft and slide it down the shaft till you reach full draw, then measure from the throat of the nock to that point.
