It’s the question that seems to haunt every Reddit thread and Instagram comment section whenever a new episode of Jersey Shore: Family Vacation drops. You see him standing next to Pauly D, looking relatively lean, and then you see him next to Snooki, looking like a giant. It creates this weird optical illusion. So, how tall is Vinny Jersey Shore actually?
The short answer? He’s not as tall as his "Keto Guido" confidence might make you think.
Vinny Guadagnino stands at 5 feet 7 inches tall (1.70 meters).
Now, if you’ve spent any time on celebrity gossip sites, you’ve probably seen some outlets claim he’s 5'9" or even 5'10". Honestly, that’s just classic Hollywood rounding. In the world of reality TV, everyone gets a two-inch "lift" in their bio. But fans who have met him in the wild—at his Chippendales residency or just wandering around Staten Island—consistently report that 5'7" is the real-deal number.

Why the Confusion About Vinny's Height?
TV is a lying medium. It’s all about angles and who you’re standing next to. On Jersey Shore, Vinny is part of a cast that is, quite frankly, vertically challenged.
When you spend a decade standing next to Nicole "Snooki" Polizzi, who is barely 4'8", anyone is going to look like a starting forward for the Knicks. Even Deena Cortese is only about 4'11". Because the women on the show are so petite, Vinny looks "normal" or even tall by comparison.
Then you have Ronnie Ortiz-Magro. Ron is roughly 5'6", and because he’s built like a literal brick house, his height is often the butt of the joke. Vinny, being much leaner, gives off a more elongated silhouette. It's basically a trick of the light and some clever wardrobe choices.
The "Keto Guido" Transformation and Proportions
Height is one thing, but Vinny’s frame has changed a lot since 2009. Back in the Seaside Heights days, he was just a skinny kid from Staten Island. Fast forward to 2026, and he’s the self-proclaimed "Keto Guido."
He dropped about 50 pounds by cutting out the pasta (sorry, Ma!) and focusing on high-fat, low-carb living. When you’re 5'7", every five pounds shows. By leaning out and getting shredded for his Las Vegas residency, Vinny actually looks taller than he did in the early 2000s. It’s all about the proportions.

- Height: 5'7" (170 cm)
- Weight: Usually fluctuates around 160-165 lbs

How He Measures Up to the Other Boys
Let’s look at the "MVP" crew. Mike "The Situation" Sorrentino usually claims to be 5'11", but most people who've run into him at a gym in Jersey say he's closer to 5'9". Pauly D is also in that 5'9" to 5'10" range, especially with the hair stiffened into a structural masterpiece.
So, Vinny is definitely the "little brother" of the main trio.
Does it matter? Probably not to him. He’s managed to parlay a reality gig into a career as a Vegas headliner and a best-selling author. He’s proof that you don't need to be 6'2" to have a massive presence on screen. Plus, his jumping rope skills—which he posts about constantly—are easier to pull off when you aren't lugging around a giant frame.
What Fans Say After Meeting Him
Reddit is usually the place where the truth comes out. One fan noted on a thread that they saw Vinny at an appearance and were "shocked" at how small he was in person. Another mentioned that "he’s definitely 5'7" because I’m 5'6" and we were eye-to-eye when he had sneakers on."
It's a common theme with reality stars. We see them as these larger-than-life characters, but in person, they’re just... regular-sized humans.

The Takeaway for Fans
If you're wondering how tall is Vinny Jersey Shore because you're trying to win a bet or just curious about the physics of the Shore House, stick with 5'7". He’s a relatable height for a guy who has made a career out of being the "normal" one (mostly) in a house full of chaos.
Next time you watch Family Vacation, look at his feet. If he’s wearing those chunky designer sneakers, he might be cheating the system by an inch. But even without the help, he’s doing just fine.
