It's really more to do with the length, and profile of the bow in question.
Normally, the longer the bow, the higher the brace height will need to be, but then the profile of the overall bow comes into play, and will also have an impact on where the best brace height will fall.
Speaking of recurves primarily - A deflex style bow will generally have a sweet spot brace height higher than the sweet spot brace height of a more straight handle, or reflex handle.
The thing about that is - even though the brace heights will differ on different handle profiles, on the same length bows you will find the measurements from the fades of the limbs to the string to be close to the same.
An example of that would be:
I have two 64" bows.
One with about a 2" reflex riser, the other with about a 2" deflex riser.
The reflex riser bow shoots best with a 7-1/2" brace height.
The deflex riser bow shoots best with a 8-3/4" brace height, yet when I measure from the fades of the limbs to the string on either bow the measurement is almost exactly the same, which means even though the brace heights are different, the limbs on both bows are preloading best at about the same spots.
Hope that made some sense.
