Start with measuring your inseam. Height alone can be very misleading. In my youth I was 5'10 1/2". I am now a tad under 5'9" in the morning. Then and now the perfect size for me is 54-55. Why? Because then and now my inseam is 32.5". Oh, and be careful with the manufacturer's sizing. My CAAD 12 is labeled a 52 but measuring it with a virtual TT it is actually a 54-55. That's due to the sloping TTs that predominate.
