Single Bed Size


A single bed, as the name suggests, is a size that is ideal for one person. This is often the bed placed in children’s rooms, spare bedrooms and also school dormitories.

This is because its dimensions are a perfect fit for a standard room of average size. Single bed size is approximately 39 inches by 75 inches in US standard mattress sizes.

However, this is not only standard single bed that is available in the market today. There are several other single bed types that are being sold in other parts of the world and the sizes may have a slight difference when measured against the US standard single or twin bed size.

In the US, there are two other twin or single bed sizes, offering either a wider or longer bed; or both. 

The size that comes after the standard single is the extra long single and this measures 39 inches by 80 inches, giving you a bed that is 5 inches longer than the regular single. This size is actually one that is more commonly found in school dormitories.

The three quarter bed is actually a single type as well and this one is wider than a regular single. This measures about 48 inches in width by 75inches in length. Finally, there is the super single, and this is approximately 48 inches in width by 84 inches in length.
