A queen size bed mattress measures 80 inches long; the total length of a queen size bed varies based on the dimensions of the frame, headboard and footboard. The mattress is 5 inches longer than full or twin size bed mattresses, which both measure 75 inches long.
Introduced in 1958, the queen size bed is a popular choice for couples. The bed, measuring 60 inches wide, provides 5 inches of additional length and 6 inches additional width over a traditional full size bed. Queen size bed mattresses are available in various heights. A simple foam mattress is about 4 inches high, while a luxury pillowtop innerspring mattress is available in thicknesses exceeding 19 inches.
