I am very new to bowhunting but wan tto give it a shot this fall....I just bought a used bow and I need to get the draw length the right length...hwo do I determine this??

Start with wingspan (or persons height in inches) and divide by 2.5. That'll get you close (unless you're a gorilla) and you can fine tune from there.

Go to an archery shop. They have a bow you can draw to measure your proper length.
