Standard bed sizes are based on mattress dimensions, which vary from country to country. Bed sizes may also vary depending on the design and ornamentation of the bed frame. Dimensions and terminology differ worldwide, as most countries maintain their own standards. In addition, two mattresses with the same nominal size may have slightly different dimensions due to manufacturing tolerances, padding, and support type. Mattress and bedding sizes may not always correspond.
Nomenclature
Naming standards on different bed sizes and their corresponding actual measurements can vary across national standards. Examples of such nomenclature are names like "Single", "Full" or "Double", "Queen" or "King" size. Sometimes the naming standards are further divided by adding adjectives such as "Narrow", "Long", "Extra Long", "Wide", "Extra Wide", and so on, which also can vary across national standards.
For example, a King size bed may measure (in width by length):
- 152 by 198 cm (60 by 78 in) in the UK.[1]
- 165 by 203 cm (65 by 80 in) in New Zealand.[2]
- 180 by 190 cm (71 by 75 in) in Portugal, but is also available in 195 and 200 cm (77 and 79 in) lengths.[3]
- 180 by 200 cm (71 by 79 in) in Indonesia.[4]
- 183 by 191 cm (72 by 75 in) in Singapore[5] and Malaysia.[6]
- 183 by 203 cm (72 by 80 in) in Australia.[7]
- 183 by 216 cm (72 by 85 in) in India.[8]
- 193 by 202 cm (76 by 80 in) in the US.[9]
Because of the growth of international trade and the above potential cause of confusion, bed sizes are becoming more standardized. In most countries, using the International System of Units, bed dimensions most often appear in centimeters, and often only by width and length.[10] In the United States, Canada and other regions influenced by the former British Empire, dimensions are often in inches.[11]
Africa
South Africa
In South Africa, bed sizes have standard lengths of either 188 or 200 cm (74 or 79 in),[12] with the latter being called "XL" variants. XL mattresses have the same widths as their non-XL counterparts.[13] The 200 cm (79 in) XL length is recommended for persons over 183 cm (6 ft) tall.[14]
- Single: 92 cm (36 in) wide
- Three-quarter: 107 cm (42 in) wide
- Double: 137 cm (54 in) wide
- Queen: 152 cm (60 in) wide
- King: 183 cm (72 in) wide. Equal to the width of two single mattresses.
- Super king: 200 cm (79 in) wide. Available in XL length only.
Europe
Europe may traditionally have had more variations in national bed size standards than any other part of the world,[15] but in the recent years a few sizes have become more common than others. Bed sizes are defined in centimeters in all European countries, although supplementary Imperial equivalents are sometimes shown in the United Kingdom.
Today, the most common widths sold by pan European retailers are:
- 90, 100 and 120 cm (35, 39 and 47 in) for single beds.[16]
- 160, 180 and 200 cm (63, 71 and 79 in) for double beds.
Other sizes are also available in some European countries (e.g., 80 or 140 cm (31 or 55 in)), but the widths listed above are the most common when looking at the European market as a whole, while 135 cm (53 in) and 150 cm (59 in) (nominal) are more typical in the UK and Ireland.
Today, the 200 cm (79 in) length is the most common bed length sold by pan-European retailers. Lengths of 210 or 220 cm (83 or 87 in) are often also available by special order. The longer beds are intended for taller people,[17] and as a rule of thumb 210-centimeter beds may be recommended for people 190 cm (75 in) or taller, while 220 cm (87 in) beds are recommended for people over 200 cm (79 in) tall.[18]
France
In France, single size beds are usually:
- 90 by 190 cm (35 by 75 in)
- or 90 by 200 cm (35 by 79 in).
The most common sizes for double beds are:
- Valet size 140 by 190 cm (55 by 75 in)
- Queen size 160 by 200 cm (63 by 79 in)
- King size 180 by 200 cm (71 by 79 in)
Italy
In Italy, beds are classified by name and use the term piazza as in "place". Standard sizes are:[19]
- una piazza (literally "one place") or singolo ("single"): 80 by 190 cm (31 by 75 in) and 90 by 190 cm (35 by 75 in)
- una piazza e mezza (literally "1 1⁄2 places") or Letto da prete (literally "priest's bed"): 120 by 190 cm (47 by 75 in)
- piazza e mezza francese (literally "French 1 1⁄2 places"): 140 by 190 cm (55 by 75 in)
- due piazze (double, literally "two places") or letto matrimoniale (literally "matrimonial bed"): 160 by 190 cm (63 by 75 in) and 180 by 190 cm (71 by 75 in)
Northern Europe

UK and Ireland
In the United Kingdom and Ireland, beds are measured according to the size of mattress they hold,[22] not the dimensions of the bed frame itself; bed frame sizes are not standardized and may differ between manufacturers.[1][23] Listed below are the typical bed sizes from the National Bed Federation, which is the trade association for the majority of British and Irish bed manufacturers and their suppliers.[24] Most NBF manufacturers use designs dimensioned in feet and inches with the metric indicators not being exact equivalents.[25] There can legally be a tolerance of up to ±2 cm (0.8 in) between the quoted measurements and the size of the mattress itself.[26]
| Size | Dimensions | ||
|---|---|---|---|
| Feet and inches[23][1] | Centimeters | Inches | |
| Small single | 2ft 6in x 6ft 3in | 30 by 75 in | 76 by 191 cm |
| Single | 3ft 0in x 6ft 3in | 36 by 75 in | 91 by 191 cm |
| Small double* | 4ft 0in x 6ft 3in | 48 by 75 in | 122 by 191 cm |
| Double | 4ft 6in x 6ft 3in | 54 by 75 in | 137 by 191 cm |
| King | 5ft 0in x 6ft 6in | 60 by 78 in | 152 by 198 cm |
| Super King | 6ft 0in x 6ft 6in | 72 by 78 in | 183 by 198 cm |
*Also known as a "three-quarter" or "four-foot" bed.[27]
Some UK retailers may have a "queen" size which refers to one of the above standard sizes, but there is inconsistency around which size specifically, with both the small double and super king being prevalent.
As well as customary UK sizes, some common European sizes can be found in the UK from imports and IKEA.[23][28] The typical length of an IKEA and other European mattresses is 200 cm (79 in), whereas UK lengths vary depending on the width of the mattress, being usually either 191 or 198 cm (75 or 78 in).[29] In 2015, IKEA started offering beds and mattresses in customary UK sizes alongside their standard European sizes.[30]
Adjustable beds or electric adjustable bed sizes differ from the standard bed size. The length of these beds differs from a standard size because the beds need to bend. So they are 200 centimetres (79 in) in length rather than 191 centimetres (75 in). King size and super king size are normally two 75 centimetres (30 in) or two 90 centimetres (35 in) adjacent beds.[31][better source needed]
Turkey
In Turkey, single size beds are usually 90 by 190 cm (35 by 75 in); long single size 90 by 200 cm (35 by 79 in); large single size 100 by 200 cm (39 by 79 in).
There is also an intermediate size used for one and a half people[clarification needed] in Turkey: 120 by 200 cm (47 by 79 in).
The most common sizes for double beds are: small double size 140 by 190 cm (55 by 75 in); young size 140 by 200 cm (55 by 79 in); double size 150 by 200 cm (59 by 79 in); double size 160 by 200 cm (63 by 79 in); double large size 180 by 200 cm (71 by 79 in); double XL size 200 by 200 cm (79 by 79 in).

North America
The sizes of mattresses use non-numeric labels such as "king" or "full", but are defined in inches. Historically, most beds were "twins" or "doubles", but in the mid-1940s, larger mattresses were introduced by manufacturers. These were later standardized as "queen" and "king", and first made a significant impact on the market in the 1950s and 1960s.[38] Standard mattress depth ranges from the "standard" size of 9 in (23 cm) to "high contour" of up to 13 in (33 cm). Below are the standard ISPA widths and heights in the United States and Canada.[39][40]
While the dimensions are specified to the half-inch below, the actual dimensions used by manufacturers or various websites may be half an inch larger or smaller.[39]
| Size | Dimensions | |
|---|---|---|
| Inches | Centimeters | |
| Twin or Single | 38.5 by 74.5 in | 98 by 189 cm |
| Twin XL | 38.5 by 79.5 in | 98 by 202 cm |
| Full or Double | 53.5 by 74.5 in | 136 by 189 cm |
| Queen | 60 by 79.5 in | 152 by 202 cm |
| King | 76 by 79.5 in | 193 by 202 cm |
| California King | 72 by 83.5 in | 183 by 212 cm |
While many furniture websites claim that David Bergeson invented the California King bed size in Concord, California, to accommodate his long legs and short arms in 1982, the International Sleep Products Association has proven that it was developed in the 1920s for Hollywood celebrities, thus predating the standard king bed size.[41][42]

Bedding in the United States must state the type of bed it is intended for, in addition to the dimensions in both inches and centimeters.[47]
In addition to the horizontal dimensions of beds, another aspect of bed size is the vertical height of the bed. This is particularly relevant for bunk beds, loft beds, Murphy beds, and canopy beds, which require more vertical space than other beds.
For both bunk beds and loft beds, it is generally recommended that there be at least 40 inches (1 meter) of vertical space between the top of the mattress and the ceiling. This allows the average-sized adult to sit up comfortably in bed.[48]
For vertical Murphy beds that fold up against the wall, the ceiling height must accommodate the full length of the Murphy bed's wall frame.
For canopy beds, there needs to be suitable clearance between the top of the canopy point and the ceiling.
