Internet bike fit: I am 5'8" and my top tube is 52.5cm. But that's only half the picture due to seat and headtube angles which obviously vary wildly across frame geometry. But still - it shows that height is only one metric. I have a short torso.
This is where your LBS is your friend - if anyone even has any bikes that is.
Her last bike had a 53cm ETT, 375mm reach, 536mm stack, with a 70mm stem. Comfortable on it but I think in an ideal world would have had one size smaller.
