We know, we know. The proliferation of photographs of erstwhile couple Katie Holmes and Tom Cruise has left us all with the same burning question: Just how much taller is Holmes than Cruise? Why does she always appear to be towering over him? And why the heck does he like his women so tall?
While we can't answer the latter, we can say that Cruise stands at a below-national-average height at 5 feet 7 inches, and his ex-wife at 5 feet 9 inches.
Hollywood's elite come in all sorts of sizes. "The Social Network" star Armie Hammer swoops at 6 feet 4 inches, Howard Stern's big stage presence can be explained by his massive 6-foot-5-inch build and, at his prime, Hulk Hogan outflexed Michael Jordan by an inch at 6 feet 7 inches. Jane Lynch meets eye to eye with Jon Hamm, both at 6 feet. On the shorter end of the spectrum, Seth Green stands at a petite 5 feet 4 inches, Lady Gaga's talon nails and staggering Alexander McQueen heels add drama to her petite 5-foot-1-inch frame, while Snooki from "Jersey Shore" is one of the shortest celebrities around. The self-described meatball is only 4 feet 9 inches.
