Queen Size Mattress Dimensions: How Big Is a Queen Size Bed?

A queen size mattress is 60 inches wide by 80 inches long, or 5 feet by roughly 6.66 feet. It’s a versatile mattress, able to comfortably fit two people or provide a person with plenty of space to move around. That’s why a queen bed is the most popular mattress size.

A queen is 6 inches wider and 5 inches longer than a full mattress, but 16 inches narrower than a king mattress. If two people share a queen mattress, they each have about 30 inches of width to themselves—that’s 8 inches less than a twin XL mattress, but still enough space for most couples.

Are you considering a queen size mattress? You should check if your bedroom is at least 10 feet by 10 feet. A bed placed against the wall would leave you roughly 2.5 feet on each side and about 3.34 feet in front of the mattress. That’s plenty of room for bedroom furniture and walking space.

Other Queen Sizes

The standard queen size isn’t your only choice when it comes to a queen mattress. Alternative sizes are harder to find and may require a special order from a custom mattress maker, but they do exist and offer extra space.

The California queen is 4 inches longer than a normal queen, much like how a California king bed is 4 inches longer than a normal king. A California queen mattress can give a tall person much-needed legroom and prevent their feet from dangling over the edge.

 

An Olympic queen, which is occasionally referred to as an expanded queen, is 6 inches wider than a regular queen bed. It offers more sleeping space without requiring the floor space that a king mattress would.

 

A split queen mattress is the same size as a standard queen, but divided into halves. A split queen mattress lets each partner choose their preferred firmness for a good night’s rest. Many couples find it better than compromising on a mattress that suits neither of them.

More Mattress Sizes

When it comes to mattress sizes and dimensions, a queen mattress isn’t the right choice for everyone. You might be a single sleeper who needs a bed size that fits into a smaller room, or you might need a larger mattress to share with your partner. We will give a brief overview of your other options so that you can be confident you’re choosing the mattress that’s right for you.

Twin

Size: 38 inches by 75 inches

A twin size mattress is the smallest size that most sleepers would consider—a crib mattress is technically the smallest standard size. It’s a popular choice for a child’s bedroom, whether it’s a single or a bunk bed for two to share. Twin beds are also used in small guest rooms and studio apartments.

Twin XL

Size: 38 inches by 80 inches

A twin XL size mattress has 5 inches of extra length than a standard twin mattress. If you want a mattress that can accommodate a child’s teenage growth spurt, a twin XL mattress is a smart choice. It’s also the bed size most college dorms have, although a few do contain full size mattresses instead.

Full

Size: 54 inches by 75 inches

A full size mattress, sometimes called a double bed, offers 16 inches of extra width than a twin mattress. It’s an excellent choice for people who like to sprawl or tend to toss and turn while they sleep.

Some couples do try to share a full size bed, but we suggest a queen size if you and your partner are looking for a mattress. Sleeping on half of a full mattress is like sleeping on a crib mattress, with about 27 inches of width.

If you’re a taller sleeper, you might want to consider a full XL mattress. It offers 5 more inches of length than a standard full bed. However, it’s not a common size and may require you to hunt online to find one.

King

Size: 76 inches by 80 inches

Also known as an eastern king, a king size mattress is the largest standard size mattress. It’s best suited for master bedrooms that are at least 12 feet by 12 feet.

Couples who feel that a queen size mattress is too small might want to consider a king size bed. If you’re interested in comparing the differences between the two, check out our king vs. queen mattresses article.

California King

Size: 72 inches by 84 inches

A California king size mattress, sometimes called a Western king, is 4 inches longer and 4 inches narrower than a standard king bed. People taller than 6 feet might want to try a California king mattress if a regular king mattress feels cramped.

A California king bed usually costs about as much as a standard king mattress. However, bedding accessories such as bed frames, box springs,

Taking Care of Your Queen Size Mattress

Once you’ve chosen your perfect queen mattress, make sure you take the time to care for it. Just a little bit of time spent caring for your bed can extend its lifespan.

You should try to wash your sheets weekly to prevent dust mites and debris from settling into your mattress. If you use a comforter encased in a cover, you should clean the cover weekly while limiting your comforter to a wash once or twice a year.

We strongly recommend a cover for queen size comforters, as most comforters are too big to fit in the average home’s washer and require professional cleaning. It’s easier and less expensive to bring it in every six months than once a week.

To further keep your mattress clean, give it a quick vacuum in between sheet changes to suck up any dirt or allergens that your body might otherwise grind into your bed.

Your mattress should be rotated every three to six months. With a queen size mattress, you might need an extra set of hands to help you lift and turn the bed.

You’ll want to wash your pillows at least every three to six months—pillows can collect all sorts of stuff such as sweat, hair, and dead skin. Just double-check that your queen size pillow is machine washable since some types can be damaged by agitators, such as solid memory foam pillows.
