can anyone tell me how to measure my draw length?

It's not an perfect check but usually gets you pretty close.

Take a wingspan measurement. You will need help for this. Arms spread out like a T. Fingertip to Fingertip. Take that number and divide by 2.5

Like I said, it's not perfect and for some people, it doesn't work. However, it works for most.

Go to a pro shop, and they can help you. They can use an extra long arrow, let you draw to your anchor point, and then measure the arrow for you......that will give you your draw length.........
