Bed size

Single size bed

Standard bed sizes are based on standard mattress sizes, which vary from country to country. Bed sizes also vary according to the size and degree of ornamentation of the bed frame. Dimensions and names vary considerably around the world, with most countries having their own standards and terminology. In addition, two mattresses with the same nominal size may still have slightly different dimensions, due to manufacturing tolerances, amount of padding, and support type.

Table of common sizes[edit]

Modern manufacturing conventions have produced many standard mattress and box spring sizes. Beds vary by country of origin as per the table below. These dimensions are for the mattress – actual bed frames are a little larger to accommodate the mattress. Mattress thickness varies considerably.

Cot sizes are not standardized and vary from 25 inches upwards. The cot size used to denote a double was 26 inches by 75 inches. A double is standardized at 54 inches.

Europe[edit]

UK and Ireland[edit]

Most modern beds/mattresses sold in the UK and Ireland are constructed using metric dimensions.

UK standard bed sizes are:

Standard single
90 cm × 190 cm (35 in × 75 in)
Small-single
75 cm × 190 cm (30 in × 75 in)
Common size for hospitality (zip & link) twin beds as beds can be combined to make a superking bed.[citation needed]
European single
75 cm × 190 cm (30 in × 75 in)
Small-double (Three Quarter)
120 cm × 190 cm (47 in × 75 in)
Standard Double
135 cm × 190 cm (53 in × 75 in)
King
150 cm × 200 cm (59 in × 79 in)
Extra-king
180 cm × 190 cm (71 in × 75 in)
Hospitality size formed by zip & linking two standard single beds together.[citation needed]
Superking/Queen
180 cm × 200 cm (71 in × 79 in)
Also known as "European King".
Eastern King
200 cm × 200 cm (79 in × 79 in)[citation needed]
Emperor
215 cm × 215 cm (85 in × 85 in)[citation needed]
Caesar
245 cm × 220 cm (96 in × 87 in)[citation needed]

It is worth noting that "bed size" in the UK generally refers to mattress size. This is because mattresses have a standard size grading, whereas bed frames do not. While many companies in the UK do offer bespoke bed making services, most mass-produced bed linens, bed frames and mattresses fit only the standard bed sizes above. A common mistake is to use a mattress size as the required space for the full dimensions of the bed and mattress.

France[edit]

Single size beds are usually 90 cm wide by 190 cm long.

Most common sizes for double beds are:
140 cm wide by 190 cm long

180 cm wide by 200 cm long (less common, but increasing popularity).

Due to the popularity of imported beds (especially from Ikea), the 200 cm length is becoming more common.[citation needed]
