I believe Bel Ami fluffs up the height on their models. I think most all of them are probably in the 5'5" range with the tallest being 5'9" or 5"10" at the most. Todd Rosset is one of the most beautiful, but if you watch him in reference to things in the room about him, I'm led to believe he is only about 5'4". I thought the Slovakian boys were the most beautiful in the world till they started using Hungarian models who are, if anything, more beautiful!
Serbs are the best EVER. D: But yea, it seems that either all of these boys are ridiculously endowed in the area or just really short.
According to the Bel Ami website Todd Rosset is 5'7 which I guess some people would consider short. But it seems like a lot porn stars are about that height.
Trevor Yates, the big dick guy, is probably the tallest, around 193cm. I think in feet, this translates in 6'3''.
