The 1.75” gives AMO draw length.
True draw length is the deepest part of the grip to the string (nocking point).
I just use a tape measure once I’m at absolute full draw and measure from the post touching the grip to my string.

 

the 1.75 is correct and might be a holdover from when people measured draw length by drawing the bow by hand and marking an arrow at the front of the riser, back when people shot recurves off the shelf so you were forced to cut your arrow at the riser or further forward

 

You can always just put the tape on front edge of riser shelf and measure to the string curve on the d loop. That way you don’t have to measure from hand groove and add the 1.75.

 

That would work if your riser was 1 3/4" thick, which none of them are today. AMO draw length is an archaic dimension and in my opinion the bow manufacturers should change the standard to true draw length, it would be much easier for most new archers to understand and measure. Even most bow shops do not measure draw length correctly, which results in confusion and a lot of people shooting incorrect draw length on their bows. Just my .02.

 

From the deepest throat of the grip to the knocking point on the string is NOT exactly correct. It has to be on the same plane as the arrow. So you would transfer the throat of the grip up to the berger hole and then measure in a straight line to the knocking point and add 1.75". Measuring from the throat of the grip to the knocking point you are actually measuring at an angle, and will give you a slightly longer measurement and incorrect measurement.

Basically, measure your brace height (throat of the grip in a straight line to your string / not knocking point). Transfer that brace height from your knocking point towards the berger hole on the riser in a straight line and reference that mark. Measure your knocking point on the string to that reference mark and add 1.75". That is AMO draw.

 

This is correct. That is why I took an old arrow and placed the tape measure @ 1.75" @ the bottom of nock (where it rests on string). Then I made marks on the arrow shaft for the desired measurements. Then using the technique mentioned above you can find the true draw length.

 

I measure mine from the front on the riser to the nock point. Not sure if that's the correct way but it measures exactly what the draw is suppose to be.

I haven't seen it in print of late, it's standard way to define draw length in the industry

 

What does "AMO" stand for? Thanks Mr. Ken

Average jack archery has a good video about this.

 

Good info here. Thanks everyone

 

So, u THINK you are a 30-inch draw.
K.
So, hook the tape measure on the pipe for your draw board,
and pull the tape out to where the nock groove touches the bowstring.

IF the tape measure reads 28.25-inches,
then, your 30-inch draw length module is delivering 30 inches of "draw length".

Now, if your tape measure says, from the pipe on the draw board
to the spot where the nock groove touches the bowstring,
if your tape measure says you have a 28.75 inch reading...
then,
you have 30.5-inches of draw.

BUT, I have the 30-inch draw module installed.
Yuppers, and the manufacturer LIED to you, and is delivering 1/2-inch TOO LONG on the draw length.

Whaddya mean too LONG?

28.75-inches from the tape measure reading taken from the draw board.
ADD 1.75-inches.
28.75 + 1.75 = 30.5-inches of draw length, from that "30-inch" module.

BUT, i was "MEASURED" at 30-inches of draw.
K.

Then, go swap out the "30-inch" module and go get a "29.5-inch" module
to get a real world 30-inch draw.

 

Good graphic. Thanks!

 

HOOK ruler...metal yardstick and I bolted a piece of wood so the edge of the wood lands at the 1-3/4 inch mark.
Hook the ruler on the pipe for the draw board,
and now you can take a DIRECT reading for draw length. No math required.

 

I also have the ez green press and draw board attachment. The post that fits in the grip when you're using the drawboard is 1.25" in diameter so I add that to the 1.75" rule and get 3" total.
I then use a yardstick and measure from the back of the post to the string and add 3" to whatever that measurement is. Hope this helps...

 

I made a tape where the 1.75" is already added. So I just measure and it shows me the correct measurement right away

 

Unless you shortened the tape 1.75 inches and added that ring you are going to be reading short. Throat of the grip sits on that black bar. So that measurement from throat of grip to nock will be measurement plus 1.75. For example: a 28 inch draw length will measure 26 1/4 from where you hooked that ring on the draw board then add the 1.75 to that which gives you 28. Unless I am just confused by your pic.

 

Take a full length shaft & mark it in inches from about 22" to the end & that is the fastest & easiest way to measure draw.

 

 

I just crank the bow back on the draw board; hook my tape measure on the draw board post; and measure to the apex of the string. The measurement can be to the pivot point of the grip OR to a vertical tangent.
