How old is Prince William and what did he look like when he was young?

PRINCE William has spent his entire life in the spotlight as a leading member of the Royal Family.

But how old is the first-born child of Prince Charles and Princess Diana?

How old is Prince William?

Prince William, the Duke of Cambridge, was born on June 21, 1982, at St Mary's Hospital in London.

This makes the prince, who is second in line to the British throne, 39 years old.

When he was a teenager, Wills started studying at St Andrews University in Scotland, before joining the RAF and training as a helicopter pilot.

He then went on to work as a search and rescue pilot from 2009 to 2013, when his service with the Armed Forces came to an end.

The Prince is a regal 1.91m tall – that's just under 6ft 3inches.

While his younger brother Harry is just a touch shorter at 1.86m – 6ft 1inch.

Prince William's wife Kate Middleton measures up at 1.75m – 5ft 7inches.

As a toddler, Prince William had blonde hair which became darker as he got older.

During his teenage years and in his early 20s, the prince had thick hair brushed forward.

It was as a teen at the University of St Andrews in Scotland William met Kate in 2001, but the pair didn’t start dating until two years later.

Before university, he was educated at the Jane Mynors' nursery school, followed by Wetherby School – both in London.

Wills then attended Ludgrove School in Wokingham.

For secondary school, William took an entrance exam and was admitted to Eton.

There he studied Geography, Biology and History of Art at A-Level.

Much like Madonna – Prince William and his brother Harry don't tend to use their last name.

They don't technically need one given that the title Prince makes them instantly recognisable.

If they were to use a surname it would be Mountbatten-Windsor.

This mix of what was Prince Philip's last name, Mountbatten, blended with the Queen's, Windsor.

However, their children use Cambridge in school, and the family are often known by this.
