How old is Prince William?
Prince William, Duke of Cambridge, was born on June 21, 1982, at St Mary’s Hospital in London.
This makes the prince, second in line to the British throne, 35 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.

What’s Prince William’s surname?
Much like Madonna – Prince William and his brother Harry don’t tend to use a 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 is Prince Philip’s last name, Mountbatten, blended with the Queen’s, Windsor.
How tall is Prince William?
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.
