THEY say that stature has nothing to do with height.
But for some of the world’s most famous and successful men, you might be surprised at how short they really are.
And even for some guys who you already knew were short, the true extent of their petite frames might be even more unexpected.
From action hero movie stars to chart-topping musicians, some leading lights are well below the average bloke’s height.
In both the UK and the US, that number is 5ft 9ins (175.3cm).
Two A-listers that clock in under that average – Tom Cruise and Justin Bieber – are even said to be planning a boxing match at the minute, so I suppose we’ll soon find out who’s the bigger man.
Here’s a rundown of famous men whose real heights might surprise you.
