For me specific I'm 5'6" with a 30"inseam on my pants. I've stood over a 17" bike and there is just a bit of clearance between the tub and my boys. When I road my friends bike I didn't notice being cramped at all, but then I was just so thrilled to be riding that I may not have noticed. I know you can't fit me over the net, I was just looking for some insight as to if one measerment was more important then the other.
