With my dd I could always tell we needed to up a size in disposables when the back didn't come up far enough to keep everything in (ie she would have explosions/leaking out of the top of the back). Also you want the rise in front to be right around the belly button for same reason - too low and you may get leaks.
I'm going to assume the same concept applies to adjusting the rise in a cloth diaper as going up a size in disposables....
