Full Answer

A twin-size mattress, which measures 39 inches wide by 75 inches long, is a common size for use in children’s rooms as well as on trundle beds and daybeds, says Sleepy’s. It offers just enough space for a single person to sleep comfortably.

The twin extra-long, which measures 39 inches wide by 80 inches long, is good for tight spaces and taller sleepers, according to the Better Sleep Council. It is often used in college dorm rooms.

Measuring 54 inches wide by 80 inches long, a full-size mattress is the same length as a twin and 5 inches shorter than a queen. It is a good size for a guest room or child transitioning from a twin bed, suggests Sleepy’s.

A queen is the most popular mattress size in America as of 2015, says Sleepy’s. Measuring 60 inches wide by 80 inches long, a queen is 6 inches wider and 5 inches longer than a full. It is recommended for guests rooms and smaller master bedrooms and provides both sleepers with approximately 30 inches of personal sleeping space.

A king mattress measures 76 inches wide by 80 inches long. The king size is becoming more popular, per the Sleepy’s website. Sixteen inches wider than a queen, it is one of the most comfortable options for two sleepers, providing each person with the same width as a twin mattress.
