Your ideal frame is 54-56cm. If you have a long torso, go for the 56cm (same if you want a more "relaxed" bike). the 54cm would be a little more sporty.

To me, seat height is more important than standover height (as long as I don't hit anything standing!). Your seat height should be.

Your inseam is 61.5cm. So your seat height should be (61.5 - 10.5) 51cm (from center of the crank to the top of the saddle.) That with a 56cm top tube should get you pretty close to a decent fit.

The top tube is a pretty important measurement. you should be able to take your hands off of the dropouts and not fall into the handlebars. You should be able to squat on your two feet with your arms in front of you in the same position as you would be on the bike - without falling over.
