what size bed is two twins

When two twin beds are put together, they will be the width of a king bed (76 inches), but slightly shorter in length. Two twin XL beds, which are 38 inches wide by 80 inches long, will make a king bed. However, two standard twin beds, which are 38 inches wide by 75 inches long, will not make a king bed as they will be shorter in length by about five inches.
