Meghan Markle is more beautiful than Kate Middleton, according to a scientific study of Britain’s A-list princesses.

A mathematical method once used by ancient Greeks reveals the 36-year old American has a face even more perfect than Kate’s, and any other British royal of her generation.

Prince Harry’s fiance was found to be 87.4 per cent accurate to the Golden Ratio of Beauty Phi.

Her eyes, eyebrows, nose, lips, chin, jaw and facial shape were measured and came closest to the Greeks’ idea of physical “perfection.”

The Duchess of Cambridge, also 36, was beaten into second place with a rating of 86.8 per cent whilst Zara Phillips, 36, was third with 81.6 per cent. Princess Beatrice, 29, was fourth with 80.7 per cent, and bride-to-be Princess Eugenie, 27, came in fifth with 79.3 per cent.

All the princesses were tested with facial mapping techniques by Harley Street surgeon Dr Julian De Silva who uses the technology in his work.

Dr De Silva, who runs the Centre For Advanced Facial Cosmetic & Plastic Surgery in London, said: “Meghan and Kate both really stood out and got significantly higher marks than the three other princesses.

“Meghan has beautiful facial symmetry and gets closer than any other princess to having what the Greeks considered the perfect face.

“Meghan has an almost perfectly shaped nose with a 98.5 per cent score, her eye position is exactly right and her gorgeous V-shaped chin is far more classically beautiful than Kate’s.

“Kate gets a very high rating, too, and stands out for having a perfect gap between her nose and lips and very strong eye spacing.

“The other three princesses all received high scores but were a little further away from Golden Ratio perfection than Meghan and Kate.

“These brand new computer mapping techniques allow us to solve some of the mysteries of what it is that makes someone physically beautiful, and the technology is useful when planning patients’ surgery.

“The Phi ratio of 1.618 has long been thought to hold the secret of beauty, and now with the computer mapping we can calculate exactly how it applies to all the royal princesses.”

Meghan’s 87.4 per cent score was a few points behind the most beautiful female celebrity – that is Johnny Depp’s former wife Amber Heard who was found to be 91.85 per cent accurate to the Greek Golden Ratio of Beauty.

Meghan was also beaten by the hottest male celebrity who was George Clooney with his rating of 91.86 per cent.

The Golden Ratio was a mathematical equation devised by the Greeks in an attempt to measure beauty.

Another doctor used the golden ratio to reveal who is most beautiful of Prince Harry’s ex girlfriends.
