What Sizes Do Mattresses Come In?

Available Mattress Sizes

To ensure years of restful sleep, individuals should select the mattress size best suited to their needs. The twin, also known as the single, is perfect for one child or adult sleeper and measures 39 inches wide by 75 inches long. For taller teens or adults, twin XL beds are best, as they are the same width but offer five additional inches of length. Two twin XL mattresses equal a king-size and is a popular way for a couple to enjoy two different mattress feels while sleeping in the same bed. This is known as a split king. Full, or double, mattresses comfortably accommodate one adult and measure 54 inches wide by 75 inches long. This size is popular with kids and teens and sometimes elderly individuals. One of the most popular mattress sizes sold, queen beds are ideal for partner sleep and measure 60 inches wide by 80 inches long. King beds are the same length as queens, though slightly wider at 76 inches. Lastly, shoppers looking for extra length can opt for the California king, which measures 72 inches wide by 84 inches long.
