Charles Shaughnessy is listed here at 182cm (his own claim) - No way Michael McKean is 180cm:

Granted Shaughnessy is closer to the camera, but the difference between Shaughnessy and McKean is more than 2cm. McKean is 5'10" MAX.

No way he was ever 5'11". In the Star Trek: Voyager episode he appeared in, he was shorter than 5'10" Garrett Wang. Although Wang had a footwear advantage (he was wearing boots opposite McKean's flat ballet slippers). Also, Kate Mulgrew (5'5" and wearing 2.5" heels) was around 2 inches shorter than him. I'd say McKean is 5'9.5" or 5'9".

I just saw Michael at a theater party for his new show in LA. He actually stood directly in front of me in the elevator on the way out. I could see the bald spot on his head. He is near 5-10 now.
