Bed size
dimensions of a mattress and the names by which standard sizes are called
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.
For example, a King size bed may measure (in width by length):
152 cm × 198 cm (60 in × 78 in) in the UK.
165 cm × 203 cm (65 in × 80 in) in New Zealand.
180 cm × 190 cm (71 in × 75 in) in Portugal, but is also available in 195 and 200 cm (77 and 79 in) lengths.

Why this record matters
“Bed size” is worth following because a concise public description often conceals a longer documentary argument. Here, size, dimensions and mattress provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q4878967. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
