AMO Draw Length
The AMO draw length is what manufacturers use to rate their bows, and it is the draw length that is printed in the bow’s specs. The AMO length is calculated by taking the actual draw length and adding 1 3/4u2033.
Checking a Bow’s Draw Length
The draw length is determined by measuring from the nock point to the point directly above the deepest part of the grip, where the arrow crosses the riser, which can be easily found using a bow square or similar device.

How long should my arrows be for a 29 inch draw?
According to our experience, if you use a 29u2032u2032 draw with compound bows, the arrow length should be 27.5u2032u2032 (29u2032u2032 u2013 1.5u2032u2032). This allows the arrow to comfortably fit on the arrow rest, but make sure your riser measurement matches up before purchasing a large quantity of arrow.
