The Difference Between a Twin and a Twin XL
At 38 inches wide, the twin size mattress is the coziest mattress on the market. Although it is possible to share a twin size bed with someone, the twin mattress size is meant for individual sleeping. It may surprise you to learn that there are actually two twin mattress size variants: the twin size mattress and the twin xl mattress. The primary difference between the two mattress sizes is their length. At 80 inches long, a twin xl mattress is 5 inches longer than the twin mattress size. It may not sound like a big difference, but it is significant enough that the two size variants have different practical uses. Below, we discuss the history of the twin size mattress and today’s practical uses for both variants.

Today, it is practically unheard of for happily married partners to sleep in separate twin size beds. Most of us see sleeping in separate beds as a sign of trouble in a relationship. Believe it or not, separate beds and twin size mattresses were actually sought after by most couples in the late 1800s and early 1900s. At the time, twin size mattresses were one of the most popular mattress sizes. Two twin size beds were initially desired in the late 1800s for health reasons, with partners trying to avoid breathing each other’s germs. In the early 1900s, separate beds indicated forward thinking for partners who wanted to balance their partnership with autonomy. By the 1920s, having separate twin beds was considered a “desirable, modern and fashionable choice”. In fact, the revolt of partners against twin size beds did not take place until the 1950s and 1960s. A negative association between couples and twin beds still persists, which means the twin mattress size is most commonly used for children or single adults.
Twin Size Mattress
The regular twin size mattress is 38 inches wide and 75 inches long, making it 5 inches shorter than the twin XL mattress size. Due to its cozy size, the twin mattress is perfect for young kids and often fits easily in a child’s bedroom. The twin mattress is also great for a guest room or for small bedrooms – just enough sleeping space without taking up too much room. If you need a twin size mattress for your children’s bedrooms, a guest room, or a smaller room in your home, check out our mattress selection at BedInABox.com.

The twin XL mattress size is 38 inches wide and 80 inches long, 5 inches longer than the regular twin mattress size. The twin XL is perfect for taller sleepers who need a high-quality mattress in a small space. It is also the most commonly used mattress in university dorms for college students.
The twin XL mattress has an additional, and helpful, function. When you combine two of them, they form a split king mattress. Remember, a king mattress size is 76 inches wide and 80 inches long. That makes the twin XL mattress size perfect to use as a split king mattress on an adjustable bed frame. When you use two twin XL mattresses versus a single king size mattress on a king size adjustable base, then each sleep partner can have his or her own adjustable settings while technically sleeping in the same bed.
At BedInABox®, we also offers five different mattresses that are all available in the twin XL mattress size. We offer a mattress design suitable for everyone, as well as bed frames and adjustable bases perfectly suited for your twin xl mattress.
