Tips to help measure your draw length
Quotes from Archers on the Archery Network
Draw length is measured from the string to the far side of the shelf,
which is 1 3/4 inches longer than so-called "true draw"
(which is measured to the throat of the grip).


Stand flat against a wall and have someone mark the tips of your middle fingers
outstretched (wing span) and then measure that distance between the marks
with a tape. Take that measurement and subtract 15 inches and then divide that
number by two. This gives you your correct AMO draw, give or take 1/4".
On the bow, AMO draw length is the distance from the deepest
part of the grip to the apex of the string, at full draw, plus 1 3/4".

You measure true AMO from the deepest part of the nock to the
center of the burger button hole plus 1 3/4 inches. That is the draw length
cam that you want to order. This will bring it about 1/8 inch in front of
the riser."

Like I said it's just a starting point. After you get the bow set to this draw length you can adjust from there, longer/shorter. Hope this helps. Be safe.
