What size am I?

[Ana]

I'm 5'3" and my top tube is 510mm. I was measured by my LBS and they said I had a "long torso for my height" (i.e. I have very short legs...)

My stem is also shorter than usual (70mm). So I could probably have fit the next size smaller and had a longer stem. Keep in mind that most people can ride 2 sizes, depending on their preference.

If you are proportioned like most women (shorter torso, longer legs), then I would say you are looking for a top tube about the same length as mine Remember, you can always get a little longer stem if the bike feels good (maybe a 90mm?)

Also, the best way to know if the bike fits you is to ride it

Hope this helps!
