Twin vs. Twin XL Beds: Learn the Key Differences

A twin bed, also known as a single bed, is a narrow bed that can sleep one person. These single sleepers are the most compatible choice for bunk beds and daybeds. While a full- or queen-size bed is a better fit for larger rooms (like master bedrooms), twin beds are a more common choice for children’s rooms, college dorm rooms, and home guest rooms because of their size. There are two types of twin beds: a standard twin and a twin XL.

• A standard twin bed measures 38-inches wide and 75-inches long, a little less than half the size of a king-size mattress (76 inches x 80 inches).
• Twin XL mattresses have five extra inches of length, measuring 38-inches wide and 80-inches long, making them a better choice for taller individuals than the standard twin bed. (This extra-length means that a twin XL mattress cannot fit a standard twin bed frame.)

While a standard twin-size bed and a twin XL share the same 38-inch width, there are a few differences between the two mattress types, such as:

• Length: The mattress dimensions of a standard size twin bed is 38 inches by 75 inches, whereas the twin XL is 38 by 80 inches—the same length as a queen or king-size bed. Pushing two twin XL mattresses together can create a standard king bed.
• Usage: A standard twin bed is a common choice for children’s bedrooms, where a twin XL is a popular choice for dorms or guest rooms because it has more legroom.
• Price: Twin XL beds are usually more expensive than a standard twin, which can influence which kind of mattress you buy.

Whether you purchase a twin or twin XL bed will largely depend on a few factors, such as:

• The room size: If you need a mattress for a guest room, dorm room, or small studio apartment, measure the amount of available living space to determine which will make a better fit. If you have extra space to spare, a twin XL-size mattress may be a better choice because it can accommodate taller sleepers.
• The size of the sleeper: Smaller children may fit comfortably on a standard twin, but taller adolescents, teenagers, or college students may require a longer mattress, making the twin XL a more appropriate choice.
• Your budget: A twin XL can be more expensive than a regular twin, which can affect which mattress you buy. If you just need a small, inexpensive sleeper without the extra length, a twin-size mattress may be the best mattress for affordability. However, if you have the room and the budget, an extra-long twin is a more worthy investment.
