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.
A Twin by Any Other Name. A standard twin mattress is 39 inches wide and 75 inches long. Daybed, bunk bed or trundle bed mattresses in most cases are standard twin bed sizes. Some trundle bed frames come in full size as well; the mattress may be full or twin. If unsure, measure the mattress or frame. A twin or trundle mattress is not the same as a twin XL mattress, which is five inches longer and won't fit on a standard trundle or twin frame.
