OK you experts, help a noob understand some bow basics. Let's say I have a bow with a BH of 7.5" and a DL of 30" and it fits perfectly. If the BH was an inch shorter - would I need a DL an inch longer?

Brace height to draw length
if you shortened the brace height to 6.5" and kept everything else the same, you would need an additional inch of DL on the cams to keep it at the 30" that you apparently require.
basically the powerstroke of the cams would need to be increased by 1". a 30" DL is a 30" DL no matter the bow since draw length is brace height + Powerstroke + 1.75 for AMO specifications.
hope this helps,

Thank you sir, I know some questions seem silly to seasoned bow folks but it's a lot to learn when you're new to the sport...
no , it reasons that those shooting longer draws benefit from longer brace heights , as do the rest of us
Brace height has nothing to do with your draw length!
If you properly measure your draw length with bow "X" it will be the same or real close to the same on bow "Y". A slight difference may show up if the bows have different grip angles or axle to axle lengths that causes you to use a slightly different form. Different bows could cause some archers to favor a draw length difference between bows maybe as much as .25".
A "newbie" may over time develop a better shooting form for him that would benefit from a little longer or shorter draw length than that with which he started.

very simply, no!
brace height doesn't have anything to do with your draw length.
your draw length is determened by the draw modules on the specific bow your shooting set by the manufacturer.
now if your talking about messing around with string and cable lengths yourself, that's a whole different ballgame.

OK, now I'm seriously confused.
If a bow has a 6" brace height, the string at rest is 6" from the grip. If I pull this string back 30" - I'm now 36" from the grip. If the brace height is 7" and I pull the string back 30" - I'm now 37" from the grip. Seems like physics tells me it makes a difference. I know the physical draw length is controlled by the appropriate cams & modules, what I'm talking about is the distance from the grip to the drawing hand (and anchor point).
Probably should have titled this thread "brace height to anchor point"...

Nope!
You are making it complicated. "Brace height to anchor point" is the power stroke NOT the draw length. Where the string is at when you start pulling it backwards has no bearing on when you stop pulling the string back. Grip to anchor is the draw length.
Face a wall like you are about to draw a bow. Place your bow hand against the wall. Take your release hand and "anchor" like you would after drawing a bow. For demo purposes ONLY, your draw length is the distance from the wall to your anchor point. Now take your release hand and reach forward like you were grabbing the string and draw to anchor. How far forward you reached has NO impact on the distance from the wall (bow grip) to your anchor.
If you have a 30" draw and shoot a bow with a 7" brace your draw length creates a 23" power stroke. A 30" draw shooting a 6" brace bow has a 24" power stroke.
holy crap...drawing 36" could you imagine the speed on that bow? hmm a destroyer at 80lbs and 36" draw...youd have to be like 7'5" to use it but goodness....speaking of which, if an athlete who is 7' or bigger what would they shoot...31" wouldnt be enough for them...do bow manufactures have special order or custom bows to fit someone with a 32 plus inch draw?
