What Are the Sizes of a Twin and Queen Mattress?

Twin Uses

• According to the Better Sleep Council, twins' small size makes them appropriate for use by children and as a daybed, trundle bed and a hideaway.

Twin Pros

• A twin is easier to store and less expensive relative to larger mattresses such as the queen.

Twin Cons

• Because they are too small for regular use by an adult, twins are only appropriate for children and the exceptionally small.

Queens Uses

• According to the Better Sleep Council, queen-size mattresses are appropriate for use in guest rooms and smaller master bedrooms. They are comfortable for couples who enjoy sleeping close to each other and by single sleepers who sprawl out.

Queen Pros

• Both wider and longer than the twin, the queen is a far better fit for two normal-sized adults. According to Sleepy's, bedding is also easy to find.

Queen Cons

• Although the queen is 21 inches wider than the twin, if it is used by two adults, each adult has 9 inches less width than if they were to sleep by themselves in separate twins.
