Mattress Sizes: The Ultimate Guide to Find The Best One For You - CNET

When you shopping for a mattress, there are many things to consider, including the firmness, material and the feel. Mattress size is another important factor many people forget about, but it's actually one of the most important ones. It's more than just the dimensions of the mattress, size helps determine how much you will spend on your mattress. 

You have your pick between a range of mattress sizes, from a single-person twin-sized bed (for when your kid is too big for a crib) to an extra-wide California king fit (for couples who like to sprawl). The mattress size you choose will depend on your height, weight and preferences. In this mattress sizing guide, we explore the dimensions of each bed size, from the most common to custom-made options. 

A twin size is best for children, or single sleepers who want to maximize the space in their room. Because they take up very little space, they can fit in room sizes as small as 7 by 9 feet. Twin-size mattresses are popular for kids because it's the least expensive size you can buy, and the bed won't take up as much space in their bedroom, leaving them room to play.

Twin XL is a long twin mattress and is best for taller children, young adults in college, or single-sleeping adults who need the extra leg-room. An 8- by 10-foot room is the smallest you should go to fit a twin XL mattress comfortably. It's also common for brands to have two twin XL mattresses as a split king. Keep in mind that it's harder to find bedding to fit a twin XL mattress because the size is most commonly used in college dorms. That means you can usually find plenty of twin XL bedding during back to school season. Outside of that, you might be limited in what you can buy.

Because full size mattresses are bigger than a twin, but cheaper than a queen, they're popular for young adults, or couples who don't mind cuddling to maximize the space in their bedroom. The recommended room size for a full size mattress is at least 10 by 10 feet.

A good compromise between a full and a queen size is a full XL. It offers the same width as a full mattress but is just as long as a queen. Single-sleeping adults who need the extra leg and or pet space typically would be well-off on a full XL bed. Keep in mind, though, it will be a little harder to find bedding for a full XL mattress than a full or queen. 

Queen size mattresses are best for single sleepers who enjoy their space. They're also good for couples, just as long as nobody is over 6 foot, 5 inches. It's currently the most popular mattress size in North America. The recommended room size for a queen size mattress is at least 10 by 11 feet.

A common choice for couples with kids or single-sleepers who like extra space to spread out, the recommended room size for a king bed is at least 12 by 12 feet. A larger size bed comes at a higher cost, both for the mattress and the bedding, so keep that in mind if you are on a budget.

A California king is longer than a standard king, but not quite as wide. It's best for tall single-sleepers or couples who have pets who sleep on the bottom of your mattress. 

Maybe the mattress sizes listed above don't suit what you're looking for. Instead, you want something that fits between that one random nook in your bedroom, or an extra-oversized mattress so your big family can join together for movie nights. Whatever the case may be, Healthline has a great list of the best custom mattress brands you can order from. 

Selecting the right mattress size is essential for a good night's rest. Keep these things in mind when shopping for a new mattress.

While two people can fit in a full size bed, you'll be more comfortable sharing a queen or king.

It depends on the space you have in your bedroom, and how much space you or your significant other require. For maximum space in your bedroom, a queen is perfectly suitable. Maybe even a full if you're down to cuddle. For large master bedrooms, king or California king beds would be ideal. 

As of right now, the most popular mattress size is a queen which measures 60 by 80 inches. It offers ample space for single sleepers and couples, and is more affordable than a king. 

A California king mattress measures 72 by 84 inches, making it 4 inches narrower and 4 inches longer than a king.
