You’ve probably seen the photos. Prince Charles—now King Charles III—standing next to the late Princess Diana, looking like he has a good five or six inches on her. It’s one of those things you just accept as fact because, well, your eyes aren't lying to you, right?
Actually, they kinda are.
When it comes to the question of how tall is prince charles, the answer isn't just a number on a measuring tape; it’s a weirdly fascinating case study in royal PR and 1980s gender roles. If you go by the official record, King Charles stands at 5 feet 10 inches (that’s about 178 cm).
But here’s the kicker: Princess Diana was also exactly 5 feet 10 inches.

The Mystery of the Shifting Stature
For years, the Palace went to some pretty intense lengths to make sure the public didn't see a couple of equal height. In their official engagement photos, Charles often stood on a step or a box. Sometimes Diana would be positioned a step below him or leaning forward in a way that shaved off a few inches of her stature.
It sounds almost silly now, doesn’t it?
Back then, the "ideal" image of a royal couple required the man to look physically dominant. To be the "protector." Even on postage stamps, Charles was depicted as significantly taller than Diana. It created this collective Mandela Effect where everyone just knew he was a tall guy.
The truth is, 5'10" is pretty much the definition of average for a British man. He’s not short, but he’s certainly not the "towering" figure the old portraits suggested.
How He Measures Up to the Rest of the "Firm"
If you look at the current Royal Family lineup, Charles is actually on the shorter end of the spectrum for the men.
- Prince William: He’s the real giant of the family, coming in at a massive 6 feet 3 inches. Honestly, he’s going to be one of the tallest monarchs in British history when he eventually takes the throne.
- Prince Harry: Not far behind his brother at 6 feet 1 inch.
- Prince Philip: Charles’s father was a solid 6 feet tall in his prime.
- Queen Camilla: She stands at 5 feet 8 inches, which is why she and Charles look "right" together in photos without any trickery—he has a natural two-inch lead.
It’s interesting to see how the height genes shifted. Both William and Harry clearly took after the Spencer side of the family or perhaps some of Prince Philip’s Mountbatten height. Charles, meanwhile, stayed closer to the stature of his mother. Queen Elizabeth II was about 5'3" (though she reportedly lost an inch or two as she got older), so Charles was always quite a bit taller than her.
Why the Height Obsession Still Matters
You might be wondering why we even care about how many centimeters a 70-something-year-old monarch measures.
Basically, it’s about the "Alpha Effect."
Sociologists have pointed out that we subconsciously associate height with leadership and authority. When Charles was the Prince of Wales, there was a lot of pressure for him to embody a specific type of masculine power. Today, things are different. We see William and Kate standing side-by-side without any obvious attempts to hide her height—and she’s 5'9", nearly as tall as her father-in-law.
Even in the world of TV, this has caused a stir. If you watched The Crown, you might have noticed Elizabeth Debicki (who played Diana) absolutely towering over Dominic West (Charles). Debicki is 6'3", which is way taller than the real Diana, while West is 6 feet flat. It flipped the real-life dynamic on its head.
Royal Heights: A Quick Reference
To keep it simple, here is how the measurements stack up for the core family members:
King Charles III: 5ft 10in (178 cm)
Princess Diana: 5ft 10in (178 cm)
Prince William: 6ft 3in (191 cm)
Prince Harry: 6ft 1in (185 cm)
Queen Camilla: 5ft 8in (173 cm)
Kate Middleton: 5ft 9in (175 cm)
What to Watch For Next Time
Next time you're scrolling through old archives or watching a documentary, look at the shoes. Diana was famously requested to wear "flats" or very low kitten heels when appearing with Charles to avoid looking taller than him.

Contrast that with today.
Camilla wears whatever she likes, and the height difference is just... there. It’s a small detail, but it tells you a lot about how much the Monarchy has—or hasn't—changed its approach to image over the decades.
If you want to get a real sense of his scale, look for candid "unposed" photos from the 90s. When they are walking on level ground at a polo match or leaving a plane, that’s where the 5'10" reality finally matches the 5'10" myth.
Actionable Insight: If you're ever comparing heights for a project or just a trivia night, always check if the subjects are standing on the same plane. Royal photography, especially from the 20th century, is rarely as straightforward as it looks. Focus on "candid" shots for the most accurate visual data.
