Hollywood is a hall of mirrors. You think you know how tall someone is because you’ve seen them on a 60-inch OLED screen, but then you see them at a grocery store in Los Feliz and realize they're actually tiny. Or a giant. When people ask how tall is Kat, they usually aren't talking about one person.
"Kat" is one of those ubiquitous celebrity nicknames that applies to everyone from tattoo moguls to vampire-hunting witches. Finding the real numbers is surprisingly hard because agencies love to add an inch for "presence," and fans love to argue about it on Reddit. Honestly, if you’ve ever fallen down a CelebHeights rabbit hole, you know the stakes are weirdly high.
Why Kat Dennings Looks Taller Than She Is
If you’re wondering about the 2 Broke Girls star, you’ve likely seen her tower over people in heels. But Kat Dennings stands at about 5 feet 4.5 inches (164 cm).
She’s got that classic "screen presence" where her personality and style make her seem like she’s pushing 5'8". On the set of 2 Broke Girls, she was often paired with Beth Behrs, who is 5'5". Because they were so close in height, the show didn't have to do much "box work" (standing on apple boxes) to make them level.
The Mystery of Barbie Ferreira’s Height in Euphoria
This is where the internet gets messy. In the show Euphoria, there’s a specific flashback scene where the narrator, Rue, mentions that Kat Hernandez (played by Barbie Ferreira) was 5'2" and weighed 127 pounds in the fifth grade.

Fans lost their minds.
Why? Because Barbie Ferreira is actually quite tall. Most modeling agencies and official bios list her at 5 feet 8 inches (173 cm). Some fans on TikTok have dissected frames of her standing next to Hunter Schafer (who is 5'10") and Sydney Sweeney (who is 5'3") to prove she’s at least 5'8".
The 5'2" mention was a script detail meant to show she was a "bigger" kid for her age, but it ended up confusing everyone who knows Barbie is a literal runway-certified model.
Kat Graham: The Petite Powerhouse
Then we have Kat Graham. If you spent a decade watching The Vampire Diaries, you probably noticed Bonnie Bennett was usually the shortest person in a scene with Elena and Caroline.

Kat Graham is 5 feet 2 inches (158 cm).
She is a tiny human. But she’s a dancer. Dancers have this way of extending their limbs that makes them look much longer on camera. When she’s on a red carpet in six-inch stilettos, she hits 5'8", which is why her height is so frequently debated in fan forums.
The Tallest Kat: Kat Von D
If you’re looking for the Kat who actually takes up the most vertical space, it’s Katherine von Drachenberg, better known as Kat Von D.
The tattoo artist and former makeup mogul is a legitimate 5 feet 9 inches (175 cm).

When you see her in her signature platform boots, she’s easily 6'1" or 6'2". She’s one of the few famous "Kats" who doesn't need to lie on her resume to hit that "statuesque" requirement.
Quick Height Breakdown (The Real Numbers)
- Kat Von D: 5'9"
- Barbie Ferreira: 5'8"
- Kat Dennings: 5'4.5"
- Kat Graham: 5'2"
- Kate Moss (The OG Kat): 5'7"
Does It Actually Matter?
Kinda. In Hollywood, height affects casting more than we think. Short actresses like Kat Graham often get paired with shorter male leads or spend their entire careers standing on wooden crates so they can fit in the same frame as a 6-foot co-star.
On the flip side, tall women like Kat Von D or Barbie Ferreira often lean into their height as part of their "boss" or "alt" aesthetic. It’s all about the silhouette.
How to Spot "Height Inflation"
Whenever you’re looking up how tall is Kat (or any celeb), keep these three tricks in mind:
- Check the shoes. If they are wearing chunky sneakers or platforms, subtract 2-3 inches immediately.
- Compare them to hosts. Look for clips of them on late-night talk shows. Most hosts have "verified" heights. If Kat stands next to a 6'0" host and her eyes are at his shoulder, she's definitely in the 5'2" to 5'4" range.
- The "Group Photo" Logic. Find a photo of the whole cast standing on a flat surface. This is usually the only time you see their true relative height without camera tricks.
Next time you're arguing with your friends about whether a certain Kat is "tiny" or "huge," remember that the camera adds ten pounds but usually subtracts—or adds—three inches of height depending on the lens.
To get the most accurate read, look for candid paparazzi shots where the celebrity is wearing flat flip-flops or slippers. That is the only place the "industry standard" 2-inch lie finally falls apart. Use sites like CelebHeights.com for community-vetted data, as they often account for "morning height" vs "evening height" shrinkage.
