Standard Mattress Dimensions

What is a Twin Mattress?

A twin mattress, also referred to as a single mattress, accommodates one adult or child sleeper. A twin model is 39 inches by 75 inches and typically works best in a smaller bedroom, on a daybed or with a bunk bed set. While it's possible to have two sleepers on a twin size mattress, it might be too snug.

Benefits of a Twin Size Mattress

  • A twin size mattress fits in small bedrooms where space might be limited.
  • It provides plenty of room for a child to lie comfortably in bed.
  • This model works great as a bed in your guest room to accommodate one sleeper.

What is a Twin XL Mattress?

A twin extra-long (XL) mattress provides ideal comfort for tall children and adults as well as growing teenagers. A twin XL model measures at 39 inches by 80 inches, which is about 5 inches longer than a standard twin mattress. This size bed is perfect for one tall sleeper, and having two of them in a larger guest room is always a safe option. Two twin XL mattresses can be used for single sleepers or accommodating couples by pushing together both beds to make a king size bed.

Benefits of a Twin XL Mattress

  • This option fits in a smaller bedroom, especially in a college dorm room.
  • A twin size XL mattress makes a great fit in a guest room for either for single sleepers, and two models can support a couple when pushed together.

What is a Full Mattress?

A full mattress, also known as a standard mattress, is 54 inches by 75 inches and can accommodate two sleepers if necessary. While this option was originally manufactured for two people, it has become a more spacious option for a single sleeper and is a perfect option for an older child or teenager. A full size bed is typically 15 inches wider than a twin bed, offering more room for a single sleeper to move around. This type of mattress is a safe choice for a guest room because it can accommodate two people or act as a larger sleeping space for one person.

Benefits of a Full Mattress

  • A full size mattress is used as a step-up option for older children or teenagers.
  • This model acts as a good compromise between a twin and larger mattress, such as a queen or king size option.
  • The sleeping surface gives a single sleeper more space to spread out comfortably.

A queen size mattress is the popular mattress size because it's a perfect compromise if you're looking to save bedroom space while maintaining a large sleeping surface.

Benefits of a Queen Mattress

  • A queen mattress fits better in a small master bedroom or medium-sized guest room than a king size option.
  • This model gives plenty of room for single sleeper or two sleepers to spread out.
