If you’ve ever watched School of Rock or seen Jack Black high-kicking his way across a red carpet, you’ve probably noticed he isn’t exactly a tower of a human being. He’s got this compact, high-energy presence that fills up a room. But when you get down to the actual tape measure, the numbers usually surprise people. Hollywood is a place built on smoke, mirrors, and strategically placed wooden boxes (the industry literally calls them "apple boxes"), so figuring out a celebrity's true height can feel like a detective job.
How tall is Jack Black?

The short answer—literally—is that Jack Black stands at 5 feet 6 inches (168 cm).
Now, in a world of Liam Hemsworths and Jason Momoas, that might seem small. But honestly, height in Hollywood is a weirdly fluid concept. Most actors add an inch or two to their resumes. It's just part of the game. Yet, with Jack Black, that 5'6" figure is widely accepted as his "real-world" height. He doesn't seem interested in the vanity of pretending he's 5'10".
The "Little Teapot" Energy
Jack Black has actually joked about his own stature before. He once compared himself to a little teapot—short and stout. It’s part of his brand. His physicality is a huge part of why he’s so funny. Think about the scene in Nacho Libre where he’s wearing those tight blue and red wrestling tights. If he were a 6'2" muscular dude, that character wouldn't be half as lovable or hilarious. His height makes him the quintessential underdog.
When he stands next to someone like Kevin Hart, who is roughly 5'2" or 5'3" (depending on who you ask), Jack looks relatively tall. But put him next to Dwayne "The Rock" Johnson on the Jumanji press tour, and he looks like a different species. The Rock is about 6'5", which creates a massive nearly-one-foot gap. That height difference was actually used for comedic effect throughout those movies.
Is He Shorter Than 5'6"?
There is always a corner of the internet, specifically places like CelebHeights, where fans obsess over every pixel of a photo to "prove" an actor is shorter than they claim. Some fans argue Jack Black is closer to 5'5". They point to photos of him next to 5'7" actors where he looks significantly shorter.
But we have to remember shoes. Jack loves a chunky sneaker or a boot with a decent sole. If he’s standing at 5'6" in flat feet, he’s probably clearing 5'7" or 5'8" in his everyday footwear.
Also, posture is everything. Jack spends half his time hunched over a guitar or doing a comedic crouch. He isn't exactly known for standing at military attention. When he does stand up straight, that 5'6" mark is pretty much the consensus.
Why Height Doesn't Matter for the Jablinski Star
Honestly, being shorter has probably helped his career more than it’s hurt it.
The "everyman" look is what made him a star. You can relate to Jack Black. You feel like you could grab a beer with him. If he looked like a supermodel, he wouldn't have been able to pull off the role of Dewey Finn in School of Rock. That role required a guy who felt slightly out of place in a prestigious prep school—someone who felt like a chaotic force of nature packed into a small, loud frame.
He’s even talked about the struggle of not looking like a typical leading man. In a few interviews, he’s mentioned that if you don’t look like Brad Pitt, you just have to try harder. You have to be funnier, louder, and more talented to get the same attention. He clearly took that advice to heart.
Comparing Jack to Other "Short" Kings
Jack is in some pretty legendary company when it comes to his height.
- Al Pacino: Often cited as 5'6" or 5'7".
- Elijah Wood: Stands at roughly 5'6".
- Daniel Radcliffe: Is actually shorter than Jack, coming in at about 5'5".
- Tom Cruise: The most famous "short" actor, usually pegged at 5'7".
When you look at that list, you realize that height has almost zero correlation with star power. Jack Black has more charisma in one eyebrow than most 6-foot actors have in their entire bodies.
The Physicality of His Performances
What’s truly impressive is how he uses his body. Despite being 5'6" and having a "stout" build, the guy is incredibly athletic. Have you seen him do the "Cock Pushup" (at least the legendary version from Tenacious D lore)? Or his high kicks?
He’s surprisingly limpy and agile. This is a man who did many of his own stunts in School of Rock, including the stage dive at the end. That requires a lot of core strength and a lack of fear. He doesn't move like a "short guy." He moves like a rock star who just happens to be a bit closer to the ground.
Putting the Rumors to Rest
So, let’s settle it. If you saw Jack Black at a grocery store, he’d probably be about eye-level with the average person. He isn't tiny, but he’s definitely not towering.
He’s officially 5'6", and that seems to be the honest truth. No lifts, no weird camera tricks, just the man as he is.
If you're curious about how he stacks up against his co-stars in his most recent projects, keep an eye on his red carpet photos with the cast of the upcoming Minecraft movie. He'll likely be the one doing a jump-kick or a power pose, proving that being "vertically challenged" hasn't stopped him from becoming a giant in the industry.

To get a better sense of how height is managed on film sets, you can look into "forced perspective"—the technique Peter Jackson used in King Kong and Lord of the Rings to make actors appear much smaller or larger than they actually are. Jack Black has seen it all firsthand.
