Standard sizes
Modern manufacturing conventions have resulted in a limited number of standard sizes of commercial bedding for mattresses and box springs. They vary by country of origin.

The sizes in the UK and Ireland, other than the Double, vary compared to the U.S. sizes, being generally smaller. The U.S. Queen corresponds to UK King and King to Super King. The European or continental basic sizes are similar to the UK but have a set length of 2 metres. The denominations Queen, King and Super King are not used in continental Europe, and Double refers to 140 cm or any higher width. Instead of these US/UK denominations, the bed width is given in centimetres.
These dimensions are for the mattress—the actual bed frame will be a little bigger in order to fully encompass and support the mattress. The thickness of the mattress may vary considerably.
