haha I think is cute too...
Well, IMDb says that he's 5' 9ΒΌ" (1.76 m), which I think is not THAT short... But he actually IS shorter than David and Matthew. They are 6' 1" (1.85 m)
and 6' (1.83 m), respectively.
All according to IMDb, of course
And all I could remember was Joey asking Chandler to crouch (idk if it's the correct word) a little, so Joey could look taller hahahaha xD
