Princess Diana has been crowned the most attractive female royal of all time, according to science.
Research into what constitutes the ‘perfect face’ has found Princess Diana came closest to scoring 100% based on the Golden Ratio of Beauty Phi, which measures physical perfection.
Prince Harry and Prince William’s mother, who tragically died in a car crash in Paris in 1997 aged 36, was found to be 89% accurate to the Golden Ratio of Beauty Phi – used by the ancient Greeks to gauge attractiveness.
The list was compiled using the latest computerised mapping techniques by facial cosmetic surgeon Dr Julian De Silva, who runs Centre For Advanced Facial Cosmetic and Plastic Surgery and utilises the technology in his work.
The computerised facial mapping techniques measured the royals’ eyes, eyebrows, nose, lips, chin, jaw and facial shape to see who came closest to the Greeks’ idea of physical perfection.
Queen Rania of Jordan, 49, the most beautiful living royal, was runner-up to Diana with a rating of 88.9%.
In third place was former Hollywood star Grace Kelly, who became Princess of Monaco by marrying Prince Rainier, with a score of 88.8%.
She also sadly died in a car crash aged 52 in 1982.
Meghan Markle, the Duchess of Sussex, 38, came in fourth with a score of 87.4%, narrowly pipping sister-in-law the Duchess of Cambridge, 38, who was fifth with 86.8%.
Commenting on the findings Dr De Silva said: “Diana, Meghan and Kate are all very beautiful women.
“But when measured against the Greeks’ Golden Ratio of physical perfection, Princess Diana comes out on top.
“She was several points ahead of Meghan and Kate and just pipped the stunningly attractive Queen Rania to the title of most beautiful royal of all time.
“Diana scored highly for her face shape, the width of her nose, her brow area and her eyebrows. Her lowest scores were for her chin and lips.
“Meghan had the highest mark amongst the new generation of royals. She has beautiful facial symmetry, an almost perfectly shaped nose and a gorgeous V-shaped chin.
“Kate has the perfect gap between her nose and lips and has very strong eye spacing. But she was marked down for having a weaker chin and jawline than the other royal princesses.”
Princess Diana’s score of 89% was a few points behind the most beautiful woman in the world – the supermodel Bella Hadid, 23, who was found to be 94.35% accurate to the Golden Ratio.
The highest rated male star is new Batman star Robert Pattison, 33, with a score of 92.15%.
The Golden Ratio was a mathematical equation devised by the Greeks in an attempt to measure beauty.
The ratio was used by Leonardo Da Vince for the perfect human body in his famous work, the Vitruvian Man.
The closer the ratios of a face or body are to the number 1.618, the more beautiful they become.
Here’s the list of most attractive female royals in full:-
1 Princess Diana – 89.05%
“Princess Diana was a very narrow winner – there was less than 1% between her score and those of Queen Rania of Jordan in second and Princess Grace who was a very close third,” Dr De Silva explains.
“Diana scored highly for her face shape, the width of her nose, her brow area, her forehead and her eyebrows, which all got the top scores.
“Her lowest scores were for her chin and lips. Her lips are a little thin and ill-defined and her chin is less classical than some of the other women.”
2 Queen Rania of Jordan – 88.9%
“Queen Rania is the most beautiful living royal and a stunningly attractive woman,” Dr Julian De Silva says.
“She had the highest marks of all for her classically shaped chin and also scored highly for her lips.”
Dr De Silva adds that Queen Rania was marked down for her nose width and her brow area.
3 Grace Kelly, Princess of Monaco 88.8%
Dr Julian De Silva said: “Princess Grace has a timeless beauty and had the highest scores for her eye spacing and her eye position is almost perfect with a score of 99.8%. Her stunning lips also scored the highest.
“She lost marks for her chin which is a little indistinct,” he adds.
4 Duchess of Sussex – 87.4%
According to Dr De Silva Meghan Markle 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% score, her eye position is exactly right and she has a gorgeous V-shaped or heart-shaped chin which is the shape women most covet,” he adds.
5 Duchess of Cambridge – 86.8%
While the Duchess of Cambridge stands out for having a perfect gap between her nose and lips and very strong eye spacing, Dr De Silva says she was marked down for having a weaker chin and jawline than Diana.
“Nevertheless, she is a striking woman and her scores mark her out as one of the most beautiful women in the world,” he adds.
