Draw length and arrow length calculator.
From your arm span I work out the two numbers that actually matter: your estimated draw length and the right arrow length. I use the industry-standard method, the same starting point any coach uses before fine-tuning on the field. It is free, asks for no email, and gives you a reliable starting point in seconds. If you already know your draw length in inches, enter it and get the recommended arrow length right away.
Draw length and arrow length
Draw length and arrow length are calculated using the standard industry method: a reliable estimate to build from. Spine, on the other hand, is not something I will guess for you. It is selected from the manufacturer's chart, crossing your actual draw weight against your arrow length, and it is specific to each shaft model. I have linked the right source below.

What about spine?
Spine is not something you can really calculate on paper. You select it from the manufacturer's chart, crossing your actual draw weight against your arrow length, and the chart is specific to each shaft model. Then you fine-tune it with a bare shaft test. I would rather send you to the right source than give you a number that might be wrong.
