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

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.

Europe

UK and Ireland

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

Size Dimensions Notes
Small-single 75 cm × 190 cm (30 in × 75 in) Common UK size for hospitality (zip & link) twin beds as beds can be combined to make a king bed.
European single 75 cm × 190 cm (30 in × 75 in)
Standard single 90 cm × 190 cm (35 in × 75 in) Ireland standard hospitality sized single, two mattresses can be zip linked to make a Super king bed.
Small-double (Three Quarter)/Queen 120 cm × 190 cm (47 in × 75 in)
Standard Double 135 cm × 190 cm (53 in × 75 in)
King 152 cm × 198 cm (60 in × 78 in)
Extra-king 180 cm × 190 cm (71 in × 75 in) Hospitality size formed by zip & linking two standard single beds together.
Superking 180 cm × 200 cm (71 in × 79 in) Also known as "European King".
Eastern King 200 cm × 210 cm (79 in × 83 in)
Emperor 215 cm × 215 cm (85 in × 85 in)
Caesar 245 cm × 220 cm (96 in × 87 in)

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. It should be noted that a Queen size mattress in the UK is often misunderstood to be one of the larger sizes as is the case in many other parts of the world. However, at 120cm in width, it is smaller than a UK double. Another common mistake is to use a mattress size as the required space for the full dimensions of the bed and mattress.
