Bed size - wikipedia 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. In almost all territories, standard beds are rectangular but other shapes, notably circular, may be obtained by special order.

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 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. At 120cm in width, however, 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.
