XL Loft Bunk Beds

Twin and Full Basic Bed Sizes

Usually, bed sizes are defined by the width of the bed, effectively showing you how much “elbow room” you have sleeping in each of these sizes.

A standard Twin Size bed is 42.5 inches wide, 80 inches long and is most often used to sleep 1 person. This is a popular size for children under 10 years old. Most kids beds sold in the U.S. today are twin sized.

Having established basic bed dimensions, let’s get into the specifics of XL bed sizes. In North America, “XL”  means Extra Large or Extra Long, where the beds are 4 inches longer than traditional beds. So, if you compare a twin bed to a twin XL bed, the only difference is – you guessed it – 4 inches more in length!
