When you see Simone Biles fly through the air, gravity looks like a suggestion she’s politely declining. It’s wild. She hits heights off the vault that make you hold your breath, and then she sticks the landing like her feet are magnetized to the mat. But then she stands next to an interviewer or a teammate, and you realize just how small she actually is.
So, how tall is Simone Biles exactly?

She stands at 4 feet 8 inches. That’s about 142 centimeters for those of you on the metric system.
Honestly, it’s a bit of a shocker when you see the numbers on paper. In a world of elite athletes who often look like literal giants, Simone is a pocket-sized powerhouse. But here’s the thing: being 4'8" isn't just a fun fact about her. It’s actually a massive part of why she’s the G.O.A.T. (Greatest of All Time).
Why 4'8" is the Secret Weapon for the G.O.A.T.
Most people look at her height and think she’s "disadvantaged." They couldn't be more wrong. In gymnastics, being short is basically a cheat code for physics.
Physics doesn't care about your feelings; it cares about center of gravity. Because Simone is 4'8", her center of gravity is incredibly low. This gives her a level of balance on the four-inch-wide beam that taller athletes struggle to maintain. When she wobbles, she’s closer to her base, making it way easier to snap back into place.
Then there’s the "moment of inertia" stuff.
Basically, the smaller you are, the faster you can spin. Think of a figure skater pulling their arms in to spin faster. Simone’s entire body is essentially "pulled in." She can complete those triple-twisting double tucks (the Biles II) because her short stature allows her to rotate at speeds that would literally make a taller person black out from the G-force.
- Faster Rotations: Her compact frame allows for more flips in less air time.
- Strength-to-Weight Ratio: She doesn't have to move a lot of mass, but she has the muscle of someone twice her size.
- Landing Precision: Less height means less distance for her center of gravity to shift during a landing.
The Viral Height Differences: Shaq, Jonathan, and the Rest
You’ve probably seen the photos. There’s that legendary one with Shaquille O'Neal where she looks like a literal doll standing next to him. Shaq is 7'1". That’s a 2-foot, 5-inch difference.
But it’s not just retired NBA stars. Her husband, NFL safety Jonathan Owens, is about 5'11". While that’s not "tall" by NFL standards, standing next to Simone makes him look like a skyscraper. They have a 15-inch height difference. You’ll often see him kneeling down in photos just to get on her level, which is honestly pretty adorable.
It’s kind of funny because, in the gymnastics world, she’s not that much of an outlier. The average height for a female Olympic gymnast is usually around 5'1". So, Simone is still about 5 inches shorter than the average gymnast.
Comparisons that put 4'8" into perspective:
- Average American Woman: 5'4" (Simone is 8 inches shorter)
- Sunisa Lee: 5'0"
- Jordan Chiles: 5'5" (Jordan looks like a giant next to Simone!)
- Rebeca Andrade: 5'1"
Did Gymnastics Stunt Her Growth?
This is the question everyone asks. "Did she stay small because she started training so young?"
It’s a chicken-and-egg situation. While intense training and caloric deficits can delay puberty in some gymnasts, the consensus among sports scientists is that the sport doesn't "make" you short. Instead, short people are naturally "selected" for the sport because they're the ones who succeed.
If you’re 5'10", you’re probably going to find basketball or volleyball way more rewarding than trying to chuck a layout full on a floor exercise. Simone was likely always going to be petite; her biology just happened to be the perfect match for the most demanding sport on earth.
She's been 4'8" since she was about 13 years old. She once joked in an interview with TODAY that she’s "stuck" at this height, but she’s learned to love it. She used to get teased for being "swole" or having big muscles, but now those muscles are the reason she has more World Championship medals (30!) than any other gymnast in history.

The Reality of Life at 4'8"
It’s not all gold medals and viral photos. Being 4'8" in a world built for 5'6" people has its quirks.
Imagine trying to reach the top shelf at a grocery store. Or driving a car where the pedals feel miles away. Simone has mentioned before that she has to have her cars adjusted so she can actually drive safely.
But on the floor, that height is her kingdom. When she hits the "Biles" on vault—a Yurchenko half-on with a front double full off—she is generating enough power to launch herself nearly twice her own height into the air.
Beyond the Numbers: Her Legacy in 2026
As of 2026, Simone’s height is just a footnote to her staggering stats. We’re talking about 11 Olympic medals (7 of them gold). We’re talking about a woman who changed the conversation around mental health in sports after the "twisties" in Tokyo.
Her height is a physical fact, but her "stature" in the world is massive. She’s proved that you don't need to be big to be powerful.
If you're looking to apply some of the "Biles logic" to your own life or training, remember that your physical build isn't a limitation—it's a set of parameters. Simone didn't try to be a 5'10" gymnast. She leaned into the physics of being 4'8" and became the best to ever do it.

- Identify your mechanical advantages: If you're shorter, focus on agility and rotation-heavy sports or positions. If you're taller, leverage your reach and "lines."
- Focus on strength-to-weight ratio: Simone's power comes from her ability to move her specific mass with explosive force. High-intensity plyometrics are key here.
- Stop fighting your biology: Use Simone’s mindset of being "stuck" at a certain height as a lesson in radical self-acceptance. Optimize the body you have instead of wishing for the one you don't.
She might be 4 feet 8 inches, but when she steps onto the mat, she's the biggest person in the room.
To see the physics of her height in action, you can look up slow-motion replays of the "Biles II" on floor. Pay close attention to her rotation speed compared to taller gymnasts; you'll see exactly how those 56 inches work in her favor to create world-record-breaking momentum.
