Bed size

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.

Standard sizes

The standard bed sizes are:

Twin

39 in × 75 in (99 cm × 191 cm)A "single" may be the same size, or a few inches narrower.

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 two smaller box-springs (each the size of a Twin XL bed) under a king-sized mattress.

In addition to the sizes described above, other sizes have found some acceptance in North America, including:

Twin XL

39 in × 80 in (99 cm × 203 cm)

UK and Ireland

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

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

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.
