Height of big show

6'11.5"

Big Show is currently billed 7' by WWE, formerly 7'2" up until around 2006, and 7'4" in WCW as the Giant. A bill of 7'2" would be typical based on actual height difference, and 7'4" is a more typical stretch when billing someone in his extremely tall height range, and 7' even is very strange since he is unquestionably taller than that in his boots.

IMDB website shows him at 7 foot tall (see related link below).
