The future heir to the throne could also take the crown of tallest royal, as new photos showed Prince George, 12, standing shoulder to shoulder with his mother, the Princess of Wales. 

The oldest child of Prince William and Catherine is ‘growing up so fast,’ royal fans said after official pictures from George’s recent visit to RAF Coningsby were shared online. 

One X user shared a side-by-side comparison of William, then 15, standing next to his late mother, Princess Diana, and George at 12 with Catherine during the pair’s poignant trip to the RAF base. 

William’s height at the time was 179cm or nearly 5’9″, whereas George – who turns 13 next month – is already 175cm or around 5’8″. 

At 6’3, the future King is the tallest member of the British Royal Family, but ‘it looks like William’s reign won’t last much longer,’ the X user commented on Prince George’s growth spurt. 

When William’s young cousin, the Earl of Wessex, joined the Royal Family for Peter Phillips and Harriet Sperling’s wedding in the Cotswolds last month, fans were quick to point out that 18-year-old James towered over his father, Prince Edward. 

The King’s younger brother is believed to be around 6′, meaning his 18-year-old son might be between 6’1″ and 6’2″. 

In fact, he is likely to be around the same height as Prince Harry, who falls an inch below William.

Prince William 

Prince William currently holds the distinction of being the tallest royal, towering over his relatives at 6’3″. 

He stood high from a young age and was over six feet when he was just 16 years old.

Royal author Tina Brown wrote in Palace Papers: ‘By the age of 16, William possessed the Spencerian height – 6ft 1″ – which made him princely even in sneakers.’

Mike Tindall  

As a talented sportsman and former England rugby player, it may be no surprise to learn that Mike Tindall is tall.

He stands at 6ft 2″, according to TNT Sports, making him one of the tallest royals, just short of William.

Mike’s build saw him through a 17-year-long rugby career – during which he helped England win the World Cup in 2003.

He married Zara Tindall, the late Queen Elizabeth’s granddaughter, in 2011 and they have three children together.

James, Earl of Wessex 

The Earl of Wessex, who turned 18 last December, appeared ‘confident’ as he attended Peter Phillips’s ‘intimate’ wedding to NHS nurse Harriet Sperling in the Cotswolds earlier this month. 

Royal fans also couldn’t help notice how James seemed to be taller than Prince Edward, who is believed to be six feet tall. 

Footage filmed outside All Saints Church in Kemble, Gloucestershire, showed the pair chatting animatedly before joining the Duchess of Edinburgh. 

Reacting to the clip, fans remarked he looked so ‘grown up’ and that he ‘towers’ over his mother Sophie, 61, who is believed to be around 5’5″.

Prince Harry 

Stood at 6ft 2″, Harry doesn’t quite make it as the tallest royal and is just shorter than his older brother.

However, he is taller than his father and his wife, Meghan Markle, who is one of the smaller royals at 5ft 6″.

Harry’s height is a few inches taller than the average man in the UK – around 5’10”.

Arthur Chatto 

Princess Margaret’s grandson, Arthur Chatto, is another tall royal and appears to be around 6ft 1″.

When stood next to Peter Phillips, who is reportedly six foot, Arthur seems to be slightly taller.

At 25 years old, he makes his living as a member of the Royal Marines and was the first royal to join the regiment. 

His mother, Lady Sarah Chatto, is Margaret’s daughter and the late Queen Elizabeth’s niece.

Prince Edward 

Prince Edward overtakes the King, too, and stands at 6ft, taking after his late father, Prince Philip.

He is the tallest member of his immediate family, towering over his wife Sophie, the Duchess of Edinburgh.

Peter Phillips

Princess Anne’s son, Peter Phillips, is another tall member of the Royal Family and stands at 6ft.

He is slightly shorter than his cousins, William and Harry, but still stands taller than the average man in the UK.

Sam Chatto 

Princess Margaret’s grandson, Sam Chatto, appears to be around 5ft 11″ in height when compared to his brother Arthur and Peter Phillips, but it is not officially known.

Though taller than his mother, Lady Sarah Chatto, the qualified yoga instructor and pottery maker, seems to stand slightly shorter than his girlfriend, Eleanor Ekserdjian. 

The pair both studied at the University of Edinburgh and have a strong passion for art.
