I got one of those Easton draw length shafts and want to get an accurate measurement. Should I take my measurement at the very front of the bow or do you measure on the shelf above the deepest part of the grip? Thanks!

AMO is 261/4 in from deepest part of grip. Some do it from the back of the bow though.

The AMO method, and how 'you' should do it are probably opposite. AMO is for manufacturers to measure to create a consistent method for all companies. I don't manufacture bows so I do it like I always have...to the back of the bow. The bow has a back and belly. The back is away from you, the belly is facing you. Measure to the back of the bow at the sight window. That way you know you will have clearance for broadheads..depending on how much of a clearance you like.
You can fuss with the AMO thing, but it doesn't make practical sense for us folks out here in the woods.

What's the intended purpose? If you are just looking for arrow length, then measure to the back of the bow. If you are measuring your actual draw length, you measure how far you pull the string from the deepest part of the grip.

I guess the main thing is just what you really want to know?
Are you trying to figure out how long your arrows should be? Or are you more concerned with hitting a specific weight at your draw on a custom order bow? Personally, I don’t see that a few pounds either way really makes a difference unless it puts you just over a weight that you can handle really well...

If it is not an exceptionally wide bow like some of the target models or a very thin bow like natural longbows the dimensions come up very close. Like already said most use the back of the bow for convenience. >>>----> Ken

My arrows are measured and cut to be 3/4" of an inch longer at the front of the shelf. Broadhead clearance is important. No need for a special tool for this measurement. Just two people, one to draw the bow and the other with a pencil to mark the shaft. When helping some one I have them draw their bow and arrow back several times and mark the arrow.

I'm more interested in how the makers measure to calculate draw weight. From the back or the deepest part of the grip?
Unless you're using a riser-mounted clicker, an inch or so out from the back is no big deal. Or even more if you don't cut arrows at all (my 'philosophy' for carbons.)

"True Draw" was used at one time by some to measure draw length.You don,t hear that term much any more,It was used for compounds ,and over draws.

The most accurate is to have someone watch you shoot and estimate how much shaft is sticking out past the bow and then subtract that from the length of the shaft.
I frequently have people tell me their draw length measured while having someone mark the shaft only to find out that they are considerably shorter when actually shooting.
It's not un common for people to completely change the way they draw when they are getting measured.

What George and Big Jim said in combo. As for true draw its measured to the Berger button hole. Jennings used it on their compounds.

I'm asking because I want an accurate measurement for when I order a bow. I don't care about the length of the arrow because that can be played with. I want to know that if I order a bow at 28" am I actually drawing it to 28". I had assumed I was drawing very near 28", but after measuring to the deepest part of the grip in only getting 27". So I wanted to know what the standard to measure accurate draw length is?

You got several incomplete answers,including mine above. We did not understand exactly what you wanted. Maybe I can clear it up. The AMO draw length is 26 1/4" to the deepest part of the grip-- Plus 1 3/4 = 28" The standard. As I stated earlier 1 3/4 past the deepest point of the grip is usually very close to the back of the bow. If it is not an exceptionally wide or skinny bow it will very nearly be the same. Soooo to make it simple most call it 28" at the back of the bow. (the most forward face) Even most bowyers use the back of the bow @ 28" to simplify things. If you want the exact draw weight, at the exact dimension, talk to the bowyer. This small discrepancy in measuring is why so many think their bow is mis- marked a couple of pounds of draw weight. Hope that does it for you. >>>>-----> Ken

Ken, thank you! That is exactly the answer I was looking for. Maybe I wasn't clear with my original post. I knew there had to be some kind of standard...and I'm sure it's hard to get exact because of different bow designs, but that will get me very close. Thanks to everyone else that helped out too!

I would call the mfg. of the bow I want to order and discuss it with him and how he wants you to measure it. Then you are both on the same page. The old saying of K.I.S.S. usually works for most things.

If you're ordering from a custom bowyer, the simple answer is tell him how far you draw to clear your broadhead. You can use AMO standard measurment, but that doesn't tell you what you draw to the end of the shelf. We tend to confuse people with forumla that won't help you in a brick fight. Logic, which isn't used much anymore, would tell you your draw length is how far you draw an arrow safely. With a broadhead arrow especially, that will be to the back of the sight window. Common sense, eh?
The AMO (voluntary) standard is for those who make bows to sell to the public (manufacturers)..AMO means Archery Manufacturers Organization. What you should do is draw a bow and see what 'your' draw is to clear the back of the bow, then base your draw on that.

Now George, I answered his question.8^) The "formula" is not all that complicated. How long should your arrows be? Aprox. 1" past the back of the bow at full draw. You can vary that a little as needed to improve arrow flight. I do prefer all my arrows be the same length though. The formula is only need for checking exact AMO bow weight if you feel you need to know. I would if having a custom bow made. Have a good one. >>>----> Ken
