I don't think that the average height of men nowhere is so tall.
But it is true that in terms of dating heights of 6ft to 6.2ft are the most favoured.
But I still believe that if you are above average, even a little, then height is never a problem even if 6.1 ft is considered better than 5.11 for instance.
From the threshold of 5.11 and above the other characteristics (face, built etc) play the most significant role rather than 1-2 inches more.
But beyond this threshold, most of the times the extra height is more important than a better face or some muscles more.
In a few words, nobody should care if there are much 6.1-.6.3 guys out there. If you are above 5.11 then other characteristics are much more important than some extra height.
