There is no way a proof that he stands only 6'5". He even didn't claim that mark with his own words and just because it was said in one of the King of Queens Show, it doesn't mean anything. That guy had inches on Lou Ferrigno who stood 6'5" in his prime and who lost at least an inch during his upcoming age. Nowadays Lou Ferrigno looks close to 6'4" or 6'3.5" and in one of the episodes, Williams had almost three inches on Ferrigno. So 6'6" minimum could be possible for Williams although he sometimes has a 6'7" appearance but 6'5" for this guy is definitely underestimated. I totally disagree that several actors on this site have false height informations.

strong 6'6'' in my eyes and extremly big build.
Rob, don't you think 6'6'' is more possible for him?
