Everything else depends on manufacturer, you need to know what the geometry is on the bike you are looking at. If you are unfamiliar with stack and reach, you want something that has a virtual top tube (effective top tube) measurement (TT) 52cm-54cm range. You will need to fine tune your reach with a stem of appropriate length.

Thanks! I will aim for a 53cm frame.
I briefly read up on stack and reach and it seems tough to measure. Do people use two measuring tapes at once?
I just measured my old mountain bike's TT using this image guide and it's 54cm. I find I get a little back discomfort after an hour of riding on it so maybe I'll aim for a TT of 52cm-53cm on a road bike. Thank you!
