Standard bed sizes are based on mattress dimensions, which vary from country to country. Bed sizes may also vary depending on the design and ornamentation of the bed frame. Dimensions and terminology differ worldwide, as most countries maintain their own standards. In addition, two mattresses with the same nominal size may have slightly different dimensions due to manufacturing tolerances, padding, and support type. Mattress and bedding sizes may not always correspond.
Nomenclature Naming standards on different bed sizes and their corresponding actual measurements can vary across national standards. Examples of such nomenclature are names like "Single", "Full" or "Double", "Queen" or "King" size. Sometimes the naming standards are further divided by adding adjectives such as "Narrow", "Long", "Extra Long", "Wide", "Extra Wide", and so on, which also can vary across national standards.
