He looks more than an inch taller than Zachary Levi, who's listed at 6'3.5", here. So, either Zach is shorter or Ryan is taller. Chuck has some tall cast members.

Oh, I've met him several times. He is one tall dude! Very nice and a very good looking guy. I would definitely go with 6'4" or there abouts.
