Grace Kelly didn't just walk into a room; she sort of glided. People often talk about her "icy blonde" look or that legendary 1956 wedding to Prince Rainier III, but the conversation almost always circles back to her physical presence. You’ve probably seen the photos. She looked statuesque. Imposing, even. Yet, when you look at the actual data from the MGM costume department and her modeling days, the reality of Grace Kelly height weight is a bit different than the "larger than life" myth.
She was human. She had specific habits. Honestly, she even had a "snack strategy" to keep from getting "hangry" on the set of Rear Window.
The Real Numbers: Grace Kelly Height Weight and Those Famous Measurements
So, how tall was she? Most official studio records from the 1950s pin Grace Kelly's height at 5 feet 7 inches (roughly 170 cm). In an era where the average American woman was barely 5'3", she was legitimately tall. This gave her that "clothes hanger" frame that designers like Edith Head absolutely loved.
When it comes to her weight, the number most frequently cited from her 1950s modeling zed card and studio bios is 118 pounds (about 53.5 kg).
Now, let’s be real for a second.

Studio "stats" back then were often massaged for publicity. However, Grace’s measurements—34-24-35—were verified by the meticulous fittings required for her high-fashion wardrobe. She had a classic "pear" or "slight hourglass" shape that was athletic. This wasn't an accident. Her father, John B. Kelly Sr., was a triple Olympic gold medalist in rowing. The woman had "athlete genes."
Why the camera lied (in a good way)
If you watch To Catch a Thief, she looks like a giant next to some of her co-stars. This was Hitchcock's doing. He used specific camera angles to emphasize her neck and shoulders.
- Height: 5'7" (170 cm)
- Weight: ~118 lbs (53 kg)
- Dress Size: Roughly a vintage 10/12 (which is more like a modern 2 or 4)
- Shoe Size: 6B
The "Elevenses" Habit: How She Maintained Her Figure
Grace Kelly famously hated "crash dieting." She once said that a quick diet would just make her "nervous and bad-tempered." I think we can all relate to that. Instead of starving herself, she followed a remarkably modern approach to eating that focused on whole foods long before it was trendy.
She was a big believer in "Elevenses."
Basically, she’d eat oatmeal for breakfast to stay full, but by 11:00 AM, the mid-morning slump would hit. Instead of reaching for a sugary pastry, she kept a stash of carrot sticks, celery, and dried apricots on set. It was a tactical move. It kept her blood sugar stable so she didn't lose her cool during long lighting setups.
What was actually on her plate?
She mostly avoided sugar and white flour. Under the influence of nutritionist Gayelord Hauser (who was the "guru" to the stars back then), she leaned heavily into:
- Whole grains: Brown rice and whole-meal bread were staples.
- Hydration: She drank tons of water, skimmed milk, and green tea with a little honey.
- The Burger Exception: Despite her "royal" image, Grace loved a good hamburger. She didn't eat meat often, but when she did, she didn't mess around with salads.
She stayed away from alcohol for long stretches, especially when she was doing one of her "three-month detoxes" which mostly involved raw vegetable salads and plenty of fruit like apples and oranges.
The Mystery of the Wedding Dress Measurements
The most famous "Grace Kelly height weight" check happened in 1956. The wedding gown—gifted by MGM and designed by Helen Rose—is a masterpiece of engineering. It used 125-year-old Brussels lace and over 400 total yards of fabric.
But here is the kicker: the bodice was so tight it had to be literally sewn onto her.
Historians at the Philadelphia Museum of Art, where the dress now lives, note that her waist was incredibly tiny during the final fittings. Stress? Maybe. But her 5'7" frame supported the "bell-shaped" skirt perfectly. If she had been any shorter, the 90 yards of tulle in the veil and the heavy silk faille skirt would have completely swallowed her.
Moving Like a Princess: Her Secret Exercise
Grace didn't "hit the gym" in the way we think of it today. No Peloton. No HIIT.
She practiced yoga.
In the 1950s, yoga was seen as quite "bohemian" and unusual for a mainstream Hollywood star. But Grace credited it for her posture. That's why she always looked three inches taller than she actually was. She also walked everywhere. When she moved to Monaco, the hilly terrain of the principality became her natural treadmill.
What You Can Learn From Grace's Routine
Looking back at Grace Kelly height weight data isn't just about celebrity worship. There’s actually some pretty solid "old school" wisdom there that still works.
- Don't skip the "slow" carbs: Her obsession with oatmeal and whole grains is why she had the energy for 14-hour film shoots.
- Posture is a force multiplier: If you want to look taller or "fitter," work on your core. Grace's "dancerly" movement came from yoga and a sport-focused childhood.
- Precision Tailoring: Much of what we perceive as "perfection" was actually just perfectly fitted clothing. She never wore anything "off the rack" that didn't fit her 5'7" frame to the millimeter.
If you’re trying to emulate her "Graceful" aging or her classic silhouette, start with the basics. Ditch the refined sugar, find a "snack strategy" that prevents the 4:00 PM hanger, and maybe try a yoga class. You don't need to be 118 pounds to carry yourself like royalty. It’s more about how you occupy the space you have.
