Compound Bow Fitment Guide
Compound bows are designed to draw back a certain distance and then stop, which is controlled by the bow’s mechanical systems. The mechanical setting of the bow and the physical size of the shooter must match. Most modern compounds require less than 20 lb. of pressure to hold back at full draw.

How do you determine draw length for a compound bow?
To determine your draw length, stand with your back to a wall and stretch your arms out against the wall, measuring the distance between the tips of your middle fingers to the tips of your other middle fingers, or the length of both arms, hands, and chest.

Can you shorten a bows draw length?

What size arrow do I need 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.
How do you shorten the ATA on a compound bow?
If your ATA is longer than 1/8 of an inch, you must shorten it by adjusting the cable(s) and bow string. If the ATA is too short, untwist the cable(s) and bow string equally one twist at a time; if the ATA is too long, twist the cable(s) and bow string equally one twist at a time.
How do I know if my draw length is too long?
The draw length is probably too long if the bow arm drops or swings to the side. When this happens, the scapula has already pushed the bow arm out as far as it can extend before the arrow is released, leaving no room for the bow arm to go forward, so it drops or swings to the side.
Is 70 lb draw too much?
A bow with a peak weight of 70 pounds and an 80% let-off, for example, should have a holding weight of around 14 pounds.
