Overall height has little to do with sizing a bicycle. The critical measurement is inseam and then reach. IOW the proportion of your legs to your torso. E.G., I'm 6'0" and have short legs, but a very long torso. I can ride either a large or a medium frame. The large makes me feel like I'm straddling the top tube, and the reach is good. The medium feels good leg wise, but I feel more scrunched. Personally, I'm comfortable with the scrunched feeling (due to my BMX background), so I generally ride a Medium.
