It depends entirely on the bike, I think. Of my two, one is listed as an 18" frame (45cm), and it feels a bit tall when I am standing over it. One says it's 22.5" (57), and it actually feels a little short. However both bikes look "right", in that I don't dwarf either one.
TLDR, it's going to be all about feel and standover height.
