Mattress Size

You have plenty of size options when purchasing a mattress. How are they different? Read this comparison guide to find the best size for you.

There isn't a one-size-fits-all approach when choosing the right mattress. Here are some questions to consider:

  • Do you sleep alone or with a partner?
  • Are you average height or taller?
  • How much space do you have in your bedroom?

Once you know these answers, picking the right size mattress gets a lot easier. Read on to learn about each size.

Twin Mattress

  • Measurements:
    38 inches wide by 75 inches long

  • Best for:
    Single sleepers and children

Twin mattresses, also called "single beds," are the skinniest option, which makes them great for small or oddly-shaped bedrooms. They are the perfect size for most children and work great as bunk beds, too.

Plus, you can place two together to accommodate more than one sleeper. Two twins are the same width as a king mattress, but five inches shorter.

Twin XL

  • Measurements:
    38 inches wide by 80 inches long

  • Best for:
    Tall single sleepers

If you need a few more inches in length, the Twin XL mattress offers the same length as a king size bed. But it's the same width as a regular twin so fitting more than one person isn't advised.

Is There a Mattress Smaller Than a Twin?
There are two mattresses smaller than a twin—the crib and toddler mattresses. Both measure 27" wide by 52" long. Both tend to be firmer than twin mattresses.

Full Mattress

  • Measurements:
    54 inches wide by 75 inches long

  • Best for:
    Single sleepers

A full mattress, or "double," provides more width—but the same length as a twin bed. They aren't ideal for more than one sleeper since each person would only get as much personal space as a crib mattress allows.

Full mattresses are good for the average-sized teen or young adult. They are relatively inexpensive, which makes them a good transition mattress.

Full mattresses are easy to move and are still narrow enough to fit in most bedrooms.

Queen Mattress

  • Measurements:
    60 inches wide by 80 inches long

  • Best for:
    Tall single sleepers and couples

A queen mattress gives sleepers five inches more in length than a twin or full mattress. They're wider, too, which is why couples often opt for a queen.

In fact, a queen size mattress is the most popular—and most cost-effective—option. That's why you'll see them advertised more than any other size.

King Mattress

  • Measurements:
    76 inches wide by 80 inches long

  • Best for:
    Single sleepers requiring more space, couples, or people co-sleeping with children or pets

People who want more width opt for the king mattress. How much wider is it? The same as pushing two twin beds together.

Due to their dimensions, king mattresses are harder to move around. Make sure you have at least 24 inches of walking space on each side of the bed if you choose this size.

California King

  • Measurements:
    72 inches wide by 84 inches long

  • Best for:
    Sleepers taller than six feet and couples

The California king is a twist on the traditional king mattress. You lose some width in favor of extra length. This size accommodates taller sleepers whose feet would hang off the edge of a standard queen or king mattress.

It's also a good option for couples since you get more overall space than a full or queen mattress.

What to Know Before Buying a Bed

What is the biggest mattress?
"Biggest" depends on how you measure it. The California king offers the most length. But a king mattress is the widest.

How do you measure a mattress?
You'll need to measure the height, length, and width. This allows you to choose the mattress that fits best in your room.

Do I need a specific sheet size?
Your sheets play an important role in your overall comfort. Sheets that are too big can become tangled while you sleep. Sheets that are too small can come off the mattress, leaving you sleeping on an uncovered mattress.

Pay close attention to the depth of the sheets you buy as well. Some mattress, including many pillow-and euro-tops, are too tall for standard sheets.

What is the best size mattress for couples?
The right mattress size for a couple depends on your personal space preferences. Queen mattresses offer a good amount of space for those on a tighter budget. If you have the extra money, a king offers even more room. Just be sure it can fit in your bedroom.

Bottom Line

Choosing the right-sized mattress comes down to personal preference. Ideally, you should try out the mattresses in the store or buy one online that has a generous trial period. This gives you time to test a mattress' size, durability, and comfort before making a final decision.
