How can you determine the right mattress size for your needs?

Selecting the appropriate mattress size can be challenging due to the multitude of options available. Determining the right size involves considering various factors such as sleeping arrangements with a partner, children or pets, personal height, and the dimensions of your bedroom. Prior to making a purchase, it's beneficial to measure your bedroom dimensions and conduct research to feel confident in your decision. Let's explore the common mattress sizes and key considerations to assist you in finding the ideal fit for your needs.

California King Mattress Size

Dimensions

Approximately 72” X 84”

Summary

California king-size mattresses take approximately four inches of width from a conventional king-size bed and add it to their overall length. If your feet have always hung off the edge of a mattress, a Cal king bed will provide you with the length you need while still having more width than a queen-size bed.

Best for

Taller sleepers, especially those over six feet, who need a longer mattress to sleep comfortably. With slightly narrower dimensions, a Cal king mattress size is best for certain rooms where a wider king-size mattress may not fit.

King Mattress Size

Dimensions

Approximately 76” X 80”

Summary

Offering a luxurious amount of space, king mattress sizes give couples the equivalent of a twin XL mattress size to themselves. King-size beds sit atop two twin box springs pushed together to make maneuvering an entire king bed into a room much easier. King-size mattresses are wider but shorter than California king-size mattresses.

Best for

Couples or single sleepers who don’t want to compromise on sleeping area, especially if they share bed with large pets or young children and find a queen-size mattress lacking in space. Most master bedrooms can accommodate a king-size bed.

Queen Mattress Size

Dimensions

Approximately 60" X 80"

Summary

Queen bed size dimensions are the most popular because they are perhaps the most versatile bed size. Queen mattresses give sleepers enough space to sleep comfortably while still fitting in smaller bedrooms.

Best for

Adult couples or single sleepers who are looking for a mattress size they won't outgrow but that is not as tall or wide as a king bed.

Shop Queen

Full Mattress Size

Dimensions

Approximately 54" X 75"

Summary

Full-size mattresses provide a good compromise between twin and queen-size mattresses. A full bed size offers a good amount of space for single sleepers and is a good bed size option for a guest bedroom.

Best for

Teens who have outgrown their childhood beds and individuals who have smaller apartments looking for an economical price and size.

Twin XL Mattress Size

Dimensions

Approximately 39" X 80"

Summary

As the standard bed size for college dorm rooms, a twin XL mattress gives students room to stretch out but doesn't offer any more width than a conventional twin-size mattress. Although this mattress is easy to move around, adults prefer a larger bed size once circumstances allow.

Best for

Taller kids and students living in college dorms.

Twin Mattress Size

Dimensions

39" X 75"

Summary

Twin mattresses, also known as single mattresses, are slim in size, which makes them easy to fit side by side in shared kids bedrooms or stacked as bunk beds. Twin beds are the size most kids sleep on through childhood and are easy to move around.

Best for

Solo sleepers from toddlers and teens to adults who are shorter than six feet.
