Twin vs. Full Bed: What's the Difference?

Ever heard the term Twin bed, and you are wondering what it is? Twin beds are called so because they are small beds that are often sold in pairs. Also called single beds, Twin beds are about the smallest beds that are available (only bigger than a crib-size bed) in the market. Due to its size, a pair of Twin beds can be conveniently placed in a room, allowing two people to stay in the room without sharing a bed.

It comes in two forms, the normal Twin bed, and the XL Twin bed. The normal Twin bed measures 39 X 75 inches, while the XL Twin bed is 5 inches longer and measures 39 X 80 inches. Single beds, due to their narrow nature, can fit easily into tiny rooms. This makes them ideal for children’s rooms, bunks, and guest rooms that serve multiple purposes.

How Much Space Do They Need?

However, the economic prosperity that accompanied the period after World War 2 led to increasing weights of Americans, which eventually gave King and Queen bed sizes more popularity above Full bed size, but Full bed sizes are still quite relevant today.

Just like the Twin bed size, Full bed size also comes in the normal variant and the extra-large variant, its extra-large variant is 5 inches longer with a dimension of 53 by 80 inches.
