Any actor who earns the monniker "McDreamy" is clearly appealing to a wide swath of the population. But is his height a factor? Possibly. Patrick Dempsey (Derek Shepherd) from Grey's Anatomy is five-foot-ten-inches, which is a reasonably tall though not ginormous height. Still, what does it matter? The guy is not only amazingly attractive, he is a hero who saves people from the wreckage of cars!
