Bunk Bed Dimensions. The specific dimensions of bunk beds directly affect the safety of bunk bed users and also influence the selection of suitable mattresses. Traditional bunk bed dimensions include twin-over-twin, twin-over-full, and full-over-full sizes.
A full-size bed is sometimes called a “double bed” or simply a “full bed”; 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.
Standard king size beds, a.k.a., Eastern king beds, and queen size beds differ in width but not in length. A king size bed offers ample room for stretching out, while a queen size bed is better for smaller bedrooms. The upfront and long-term costs of owning a king size bed will be higher than those of a queen size bed.
A Queen size mattress in the UK is often misunderstood to be one of the larger sizes as is the case in many other parts of the world. At 120cm in width, however, it is smaller than a UK double. Another common mistake is to use a mattress size as the required space for the full dimensions of the bed and mattress.
Toddler Beds. Toddler beds hold mattresses that are the same size as crib mattresses, give or take about one-half an inch. They usually measure 27 inches wide by 52 inches long. The small size makes it easy to place waterproof pads or sheets on top of them, which will come in handy if your toddler is working on potty training.
The twin’s slightly longer cousin, the twin XL mattress is the most popular size for college dorm rooms. It’s five inches longer than a twin, making it 39 inches wide and 80 inches long. In addition to students, a twin XL mattress is a good solution for taller teenagers and individual adults with limited space.
