Twin Mattress. A twin mattress is the smallest possible mattress size, other than a crib-sized mattress. Twin mattress dimensions are approximately 38 inches wide by 75 inches long. Both twin and full sizes are approximately 75 inches long, which may be too short for some adults, especially men.
Twin Bed. Twin beds are 39 inches wide and 75 inches long, so a standard twin headboard is 42 inches wide. The twin extended headboard size is also 42 inches because the difference between the two beds is in the length. A twin extended bed is 80 inches long. The full-size bed, also known as the double bed, is 59 inches wide, not quite double that of a twin bed. The length is 75 inches.
