What size is a UK single bed?

A UK single bed measures 3ft (90cm) wide by 6ft 3in (190cm) long. The mattress is the same size. It is the standard size for one sleeper from about age 4 upwards, and the most-stocked mattress size at every major UK retailer.

When do kids move from a toddler bed to a single?

Most UK families make the move between 4 and 6 years old. The triggers are usually outgrown length (toddler beds are 140cm long, singles are 190cm) or the child climbing in and out competently. Some families skip the toddler step entirely and go from cot to single around age 3.

Can two children share a single bed?

For one or two nights, children up to about age 7 share a single for a sleepover without much trouble. As a regular sleeping setup it is too narrow: 90cm divided is 45cm per child, less than a standard cot mattress per child.
