Ever stood next to someone and realized they are way taller than they look on TV? That is basically the universal reaction people have when they see the Princess of Wales in person. We see her in photos every day, usually surrounded by security or standing next to Prince William, who is a literal giant at 6 feet 3 inches. Because he’s so tall, it’s easy to assume she’s "average."
She isn’t.
Honestly, Kate Middleton height and weight have been the subject of more Google searches than almost any other royal metric, and most of the numbers you see floating around are just flat-out wrong. People love to speculate. They see a slim woman in a tailored coat and assume she's petite.
She's actually statuesque.
The Reality of Kate Middleton Height and Weight
Let's talk numbers. The Princess of Wales stands at 5 feet 9 inches (about 175 cm). To put that into perspective, the average woman in the UK is around 5 feet 3 inches. She’s significantly taller than the average person you’d meet at the grocery store.
When she puts on her favorite four-inch Gianvito Rossi heels, she’s pushing 6 feet 1.
That is why she never looks "swallowed" by those long, heavy ceremonial robes or the dramatic floor-length gowns she wears to state dinners. She has the frame to carry them. If you compare her to other famous women, she’s the same height as Cameron Diaz and Julia Roberts. She’s even an inch taller than Meghan Markle, who stands at 5 feet 6 inches.
Weight is a trickier subject because, well, the Palace doesn't exactly release "weigh-in" stats like a boxing match. It would be weird if they did.
Most reputable sources and fashion insiders estimate her weight stays consistently around 120 to 125 pounds (roughly 54-57 kg). For someone who is 5'9", that is a very lean BMI. However, anyone who has followed her journey since the St. Andrews days knows she has always had an athletic, "sporty" build rather than a naturally fragile one.
Why the Numbers Change (And Why They Don't)
It is no secret that the Princess has been through a massive health battle recently. After her cancer diagnosis in early 2024 and her subsequent recovery throughout 2025, her appearance has naturally been scrutinized.
You've probably noticed she looks a bit different in recent photos from early 2026.
Illness changes a body. Chemotherapy is brutal. During her treatment, royal observers noted she appeared thinner, which is completely expected. But as of January 2026, she’s marked one year in remission. She’s been focusing on "slow and steady" recovery, which includes getting back to the activities she actually enjoys.
She isn't just "skinny." She’s fit.
The "Secret" to the Princess's Physique
If you’re looking for a magic pill, you won’t find it here. Kate is famously competitive when it comes to sports.
She doesn't just go to the gym; she lives an incredibly active lifestyle that most people would find exhausting.
- The Planking Obsession: Insiders have leaked for years that her favorite move is the plank. She reportedly does three versions: the basic plank, the side plank, and the "prone sky dive." She holds them for 45 seconds or more, ten times over.
- The "Solo" Gym Habit: Unlike many celebrities, she doesn't always use a personal trainer. She likes to sweat solo at the gym in Kensington Palace or run the grounds at Anmer Hall.
- Cardio with the Kids: She once told a fan that she stays thin by "running after the children." It sounds like a cliché, but with three high-energy kids and a massive Norfolk estate to run around on, it's a lot of incidental cardio.
- Cold Water Swimming: She’s admitted to being a bit of a "crazy" cold-water swimmer. The colder the water, the better. That kind of metabolic shock burns calories like nothing else.
What She Actually Eats (It's Not Just Salads)
There was a rumor for a long time that she lived on an 800-calorie diet of gazpacho and smoothies.

That’s basically impossible for someone with her schedule.
She is a fan of the Dukan Diet, particularly when she was getting back into shape after her pregnancies. It’s a high-protein, low-carb approach. But she’s also a "foodie" in a very British way. She cooks for her family. She’s talked about making spicy curries—even though William apparently can’t handle the heat—and she’s been spotted buying traditional sweets for the kids.
The real "secret" is her focus on raw foods and antioxidants. Think ceviche, goji berries, and kale smoothies. It sounds trendy, but for her, it’s about energy. You can't stand in heels for six hours shaking hands if you haven't eaten.
The Impact of 2024-2025 on Her Body Image
Coming into 2026, the conversation around Kate Middleton height and weight has shifted from vanity to vitality.
When she announced her remission, she spoke about "a new normal."
She’s being more selective about her engagements. She isn't "running on empty" anymore. This shift is visible. There's a certain "steeliness," as some royal experts call it, in her posture now. She isn't trying to fit a specific fashion mold as much as she is trying to be healthy for her three children.
It's a lesson in perspective. Even with the best chefs and the best gyms in the world, health is fragile.
Actionable Takeaways from the Princess’s Routine
If you’re looking to emulate her approach to wellness, don't focus on the "54 kg" number. Focus on the habits.
First, prioritize strength over skinniness. The reason she looks "toned" rather than just "thin" is the resistance training and those grueling planks. Second, embrace the outdoors. She is a huge proponent of "forest bathing" and the healing power of nature.
Finally, find a "competitive" hobby. Whether it's tennis, rowing, or just jumping on the trampoline with your kids, movement shouldn't feel like a chore.
The Princess of Wales uses her height to command a room, but she uses her fitness to keep up with the demands of a future Queen. As she moves further into 2026, her focus has moved toward "the healing power of creativity" and spending time in nature—a far more sustainable way to stay healthy than any fad diet.

Focus on building a body that allows you to do the things you love, rather than a body that just fits a certain dress size.
Next Steps for Your Wellness Journey:
- Start small with core stability: Incorporate a 30-minute "plank circuit" twice a week to build that functional "royal" posture.
- Audit your "incidental" movement: Look for ways to add activity to your day that doesn't feel like a workout—take the stairs or walk during your lunch break.
- Prioritize protein: Follow her lead by ensuring your meals are anchored by lean proteins to maintain muscle mass and energy levels throughout the day.
