I think it's interesting that nobody bothered to ask what type of jumping you do. Many don't realize that there are many "subgenres" of jumping (fox hunting, hunt seat, equitation, show jumping, cross country, even steeplechasing!) If you ride hunters or equitation, the stirrup length is pretty universal if you want to be in the ribbons. Recognize that in h/j/equ there's not a lot of variety to what is acceptable.
However, if you go into the jumping fields that are not judged by presentation, but by performance (show jumpers/eventers/fox hunters/chasers), you will probably notice that their stirrup lengths definitely DO vary. For example, fox hunters tend to have a longer stirrup because it's more comfortable to ride in through varying terrains over long periods of time... while SOME eventers prefer the same longer length for the same reasons, other eventers prefer an incredibly (almost ridiculous!) short stirrup because it helps us get our a$$es off the horse's back, should they take an awkward distance and catch us off guard.
All in all, I guess I'm just trying to say it depends on the type of jumping you do, and in some cases it depends on your own abilities & level of balance.
