Full Bed vs. Queen Bed. A full-size bed is sometimes called a âdouble bedâ or simply a âfull bedâ; it is bigger than the twin bed (a.k.a. single bed) and smaller than a queen-size bed. A full size bed is 54 inches wide and 75 inches long while queen size beds are 60 inches in width and 80 inches in length. 1 Dimensions.
Full bed size, also known as a âdouble/standardâ, was commonly used for two adults 30 - 40 years ago when the homes and bedrooms were built much smaller. Now it is usually purchased for single person use and sometimes smaller guest rooms. It is a tight fit for two adults and the same length as a twin. Two adults sleeping on a full size is equivalent to each person sleeping on a crib mattress (27 inches of sleep space). Most people with a sleeping partner opt for the queen size.
