Choosing a new mattress depends on a number of factors — among them, the height of the sleeper, the number of sleepers for any given bed, and the size of the room. You may also need to consider preferences for sleeping positions and the level of sprawling that takes place. But perhaps most compellingly, because we spend a large portion of our lives (about one-third, actually) sleeping on a mattress, choosing the right mattress for you is vitally important. A carefully selected mattress can make the difference between waking up refreshed and rejuvenated or waking up to aching joints.
To get you started, our experts created a guide to help determine the best mattress size for every person in your household.
As the smallest standard size for mattresses, the twin is a great bed for a single sleeper. It should be no surprise that children’s rooms often feature a twin bed.
✓ Dimensions for a Twin Mattress: 39” (W) x 75” (L)
Providing five (5) extra inches of length, twin XL beds are best for use in rooms with a single sleeper per bed. Better suited for taller individuals, the most common use of the twin XL bed is in college dorms and apartments.

Full or Standard
This size falls in between a queen and a twin size. A full bed is great for individual sleepers who prefer a roomier bed. It can also accommodate two sleepers, but they will experience a tighter fit in a full bed versus with a queen mattress.

Like a twin mattress, a full-sized mattress can be purchased as extra-long to provide more room at the foot of the bed. The full XL size is a great option for a taller sleeper who wants a bed that is not as wide as a queen-sized mattress, which can either be a preference or a necessity if your room’s square footage is limited.

Despite it often being confused for a full-sized mattress, a queen mattress is slightly larger — more specifically, it is about six (6) inches wider and five (5) inches longer. The queen-sized mattress is a more comfortable fit for two sleepers compared to the full-sized mattress. Queen mattresses are also a great standard model for any guest room or for individual sleepers who crave a spacious bed. A great go-to size, the queen size option provides ample sleeping space without taking up as much square footage as a king-sized bed.
✓ Dimensions for a Queen Mattress: 60” (W) x 80” (L)
The king-sized bed is often thought of as the largest standard-sized mattress. There are actually several options for larger beds, but the king-sized mattress is the most common. A king-sized bed is great for couples, especially if they require extra room when sleeping. It is also great for double sleepers with kids that occasionally co-sleep, as it provides ample room with a 76-inch width.
✓ Dimensions for a King Mattress: 76” (W) x 80” (L)
Despite common misconceptions, a California king bed actually has a width that is four (4) inches leaner than a regular king-sized bed. That said, a California king mattress is longer, coming in at around 84 inches.
