What is the formula for figuring out the draw length of a person by measuring their over all wing span

The 2 common formulas are

Wingspan divided by 2.5

Wingspan -15 devided by 2.

In my opinion these are only a guide and are not accurate for a lot of people, especially if one side of your body is longer than the other.

I agree. I have seen this work but I have seen it fell more often. Usually gets you in the ball park of figures however.

I've found a better gauge is to take a yard stick, place it between your collar bones in the pit of the neck so it extends straight out, extend your arms straight out (do not stretch) and see where your middle finger tips measure. IMO, much more accurate than the wingspan method.

which way do you see it "fail" most often? is the archer's optimum DL usually shorter or longer than the book's number?

Fist to the wall method will get you close, its not as fancy as some of the other ways,but will get you close. Let your pro shop fine tune it, if you dont have the gear to do it yourself.

what i do is hook on the inside of my thumb & draw the tape measure back to the corner of my mouth & it puts it exact
All the above mentioned methods will get you close... the issue isn't your draw length... it is what the bows draw length is. Does it run long?? Short?? Right on??
Depends on the bow you choose.

but don't you then need to add 1.75 inches to that figure the way the manufacturers do it? i think that is the added amount? you are measuring TRUE draw length with your method which i don't understand WHY they don't just keep things simple and use that to sell bows?
