In Hollywood, size seems to matter. At least, in terms of how tall a celebrity (especially male celebs) is. From action film sets to pairing leading ladies up with taller dudes, there's this sense that men need to be six-foot-two in Hollywood to get by.

Though some guys fit the bill, not all do, and Kevin Hart is one of them.

He's earned a reputation for being hilarious and talented, but his height is one of those things that Kevin can't joke away, no matter how much he tries.

So how tall is Kevin Hart, and is he taller than another much-talked-about sub-six-foot celebrity, Tom Cruise?

How Tall Is Kevin Hart?

Who really knows how tall Kevin Hart is? He probably does, but he's apparently not very open about sharing. While he can't help but look somewhat slight next to his relatively Amazonian wife (no really, she's not that tall, it's definitely relative), Kevin can fudge the numbers a little.

For example, some sources suggest that Kevin Hart is only about five foot two. Kevin would likely balk at that, however, because some say that he once claimed to be 5'4.5". In fact, he's made jokes about growing to "a full 5 foot five.' It seems clear that Kevin is sticking by his 5'4.5" claim.

But what's the more realistic figure?

Sources often speculate Kevin is somewhere between five feet two inches and five feet four inches tall (no mention of that missing half inch). But Kevin himself appeared to confirm his actual height -- with a lie detector test!

Kevin Hart Admitted To His (True?) Height

In a funny yet somewhat uncomfortable interview with Vanity Fair, which then wound up on YouTube, Kevin Hart literally took a lie detector test and was asked about his height.

When the interviewer asked him to confirm that he's 5'2", Kevin burst out with "Absolutely not." But at that very moment, the polygraph started ticking.

As Hart counted down from five foot four to five foot two, he seemed to become more resigned to spilling the truth.

But was the interview (and the polygraph test) authentic, or was it all just a big joke? Looking at Hart's history of joking about his height on Twitter, it's tough to say. He's completely fine with making jokes about himself, although he does say he won't change his body to appease society.

How Tall Is Tom Cruise?

Like any celebrity, there are some details about Tom Cruise's personal life that he prefers to keep under wraps. So instead of jumping on Oprah's couch and declaring how tall he is, he's always kind of kept quiet about his height.

Still, fans can see that he's not quite as tall as his ex Katie, who clocks in at five foot nine.

It seems pretty clear that the widely reported figure of 5'7" is at least close to Tom Cruise's actual height. Apart from meeting him in person with a tape measure (or check his shoes for lifts), fans can't do any more than take that number at face value.

Could Kevin Hart Be Taller Than Tom Cruise?

Fans have long suspected that Tom Cruise lies about his height. But although he may not brag about how tall he is (or isn't), it doesn't seem likely that he's lied about how tall he is all these years.

After all, many films he's been in sort of camouflage his height; Hollywood tricks can do wonders for any person's physique!

Plus, insiders have already confirmed that Tom Cruise and Sylvester Stallone are of equal height. So if Tom (and Sylvester) are five foot seven, that means they're both taller than Kevin -- by up to five full inches.

Who Is Kevin Hart Taller Than?

Since Kevin Hart is one of the shorter celebrities in Hollywood, he probably wants to know, like everyone else, who he might be taller than. When it comes to male celebrities, Kevin doesn't have much of an edge on anyone since his height is far below average (in the US, the average male is 5'9").

If there's any way Kevin wasn't lying about being 5'4.5", he's still shorter than celebrities like Bruno Mars, Daniel Radcliffe, and Lil Wayne. Despite the irony of being shorter than a guy literally named Lil, Kevin still maintains good humor about his appearance.

And he can boast that he's taller than at least one male celeb: Rob Schneider, who is reported to be 5 feet 3 inches tall. Then again, if Kevin's lie detector gag was true, then he's only taller than one well-known celeb of a smaller stature: Danny DeVito, who's 4'10".
