Also, standover height is not a science. It's kind of a preference. As said before, you need to be comfortable ON the bike, not OVER the bike. I'm sized for a 58cm frame, however, I typically ride a 55 or 56cm frame because I prefer a smaller bike. It's more comfortable for me. Standover is a little low, most likely, but when I'm ON the bike, I'm comfy and that's all that matters to me.
