Bed size

Single size bed

Bed size refers to the dimensions of a mattress and the names by which standard sizes are called. Beds themselves vary widely in size according to the size of the frame and degree of ornamentation but are sold according to the size of mattress they take. The dimensions and names vary considerably around the world, with most countries having their own standards and terminology.

Modern sizes in metric system countries are 200 centimetres (79 in) long. The traditional "double" size standard among English speaking countries, based on Imperial units, is 4'6" by 6'3" (54 by 75 inches (137 by 191 cm)), but the sizes for other bed types tend to vary.

Standard North American sizes

A pillowtop queen-size mattress.

Modern manufacturing conventions have resulted in a limited number of standard sizes of commercial bedding for mattresses and box springs. Imported beds vary by country of origin as per the table above.

These dimensions are for the mattress—the actual bed frame will be a little larger in order to fully encompass and support the mattress. The thickness of the mattress may vary considerably.^{[citation needed]}

Standard North American sizes

The standard bed sizes are:

Twin

39 in × 75 in (99 cm × 191 cm)

Full or double

54 in × 75 in (137 cm × 191 cm)

Queen

60 in × 80 in (152 cm × 203 cm)

King

76 in × 80 in (193 cm × 203 cm)

A king-sized bed may have a king-sized box spring (foundation), or, more commonly, two smaller box-springs (each somewhat larger than that of a twin bed) under a king-sized mattress.

Some older beds are only 190 cm (75 in) long, while antique beds often are even shorter as, on average, people are taller now than they used to be.^{[citation needed]}
