Packing for a holiday can sometimes be a real chore. Especially if you, like the most of us, leave it until 3 hours before the flight is due to take off.

We asked a skilled mathematician, Mark Labbett, known as the ‘Chaser’ from the ITV’s game show ‘The Chase’, to put together a packing formula to help you whizz through the crowds at the airport, without getting caught exceeding the baggage allowance.

Just follow our ingenious packing formula which calculates exactly how much your luggage will weigh and you’ll never have to frantically stuff your socks in your pockets at the check-in desk again.
