Posted on 11.27.23

When browsing through the inventory at a mattress store, shoppers should try out a variety of sizes to make sure they're making the best possible decision. The size of your mattress can impact the quality of sleep you get and your sleeping pattern. Here's a guide on the seven different bed sizes and the most appropriate body types they accommodate best!

Additionally, make sure to explore our Mattress Buying Guide and Mattress Type Guide to learn more about the different types of mattresses and what you should consider when buying one.

TWIN & TWIN XL

What Size Is a Twin Mattress?

Twin-size mattresses are 75 inches long and 38 inches wide, while twin XL mattresses are 80 inches long and 38 inches wide. Twin-sized mattresses are best for kids and most teenagers. They are perfectly sized to accommodate a single sleeper.

If you have a particularly tall child or are looking to accommodate an adult guest, consider getting an XL (extra long) twin mattress. Twin XL mattresses are often the same ones you'll find in dorm rooms on college campuses. Make sure you buy extra long sheet sets so they properly fit your XL mattress.

Benefits of Twin Mattresses

Twin beds are great for your children or single guests in a guest room. They are big enough to sleep comfortably and to allow extra space in the room, allowing you to fit more furniture in the room such as a desk or recliner.

FULL & DOUBLE

What Size Is a Full Mattress?

A full-sized mattress is 75 inches long and 54 inches wide. A full-size bed and a double-size bed are the same size. A full-size mattress or double mattress is in between a twin and a queen size. These mattresses are great for someone that isn't ready for a larger bed such as a queen, king, or California king bed.

The Benefits of a Full-Size Bed

A full or double bed will often help restless sleepers feel more comfortable. This style also comes in an extra long for taller men and women. Most adults feel more comfortable sleeping in a double bed rather than a twin even if they are sleeping alone. It also provides extra space if you have pets that like to snuggle throughout the night.

While these beds can comfortably accommodate a couple, a larger size bed may be preferable for couples who like their space. If you like to get up close and personal with your partner this is the perfect size for you. Just not ideal if you have pets or children that want to join you and your partner.

A full-size bed would also be a good choice when you're furnishing a guest room. It could easily accommodate someone by themselves or couples without compromising much space.

QUEEN

What Size Is a Queen Mattress?

A queen-size mattress is 80 inches long and 60 inches wide.

The most popular mattress size for couples is a queen-sized mattress. It is large enough to comfortably accommodate two people. This style does not come in an extra-long size. If you like to have a good amount of space while sleeping this is the mattress for you. This mattress size is great for smaller master bedrooms.

The Benefits of a Queen Size Bed

If you like to have plenty of space for yourself or even as a couple this is a great choice. It can even allow some extra space for pets and children. Make sure to consider a queen bed if you would like to have more space to sleep with your family and your bedroom space allows for it.

KING & CALIFORNIA KING

How Big Is a King-Size Mattress?

A king-size mattress is 80 inches long and 76 inches wide, while a California king-size mattress is 83.5 inches long and 72 inches wide.

A king-size mattress is a very large mattress that can more than accommodate two people. It is equivalent to two twin-size mattresses. This is the size bed you want to fill up your large master bedroom!

California king mattresses are the extra-long version of a king-sized mattress, but they are not as wide. It is still a very large bed that can more than accommodate two people.

There are also custom king-size beds on the market that are even larger, but they come with extreme price tags.

Before you consider purchasing a king-size mattress, you must make sure that you have enough space in your bedroom to properly fit this mattress size. Because these mattresses are so large, they can easily compromise your bedroom space if you do not have enough room.

The Benefits of a King-Size Bed

Just like queen mattresses, their spacious dimensions provide you with plenty of space to stretch out while minimizing any sleep disruption from partner movement. The extra width and length of king-size beds accommodate any sleeping position, allowing you and your partner to enjoy your ideal sleeping posture. The best part? You can also easily have children and pets in bed with you and still have plenty of space. These are the true XL beds on the market!

Additionally, you can find split king mattresses and split California king mattresses. These mattresses are like a dream come true for couples who have very different sleeping styles. A split model offers two mattresses in one, so each partner gets their own “zone” that meets their sleeping needs. For example, if you are a side sleeper who prefers a soft mattress and your partner is a stomach sleeper and prefers a firmer mattress, then a split model is an excellent option. Finally, these mattresses often come with adjustable bases, so each one can elevate your mattress for improved posture.

What Mattress Size Do I Need?

Customers often ask about the best mattress size, but the answer depends on what they need. If you're not sure which size is right, think about who will be using it. Is it just you, or will others share the bed? It's important to choose a mattress with enough space for comfortable sleep. Kids usually do well with a twin mattress, while adults might prefer a full-size one. Although a full mattress can accommodate a couple, most couples prefer the extra room of a queen mattress, which is the most popular choice. If you're tall or have a big family sharing the bed, a king-size mattress could be a better option.

While it can be “nice” to have extra space on your bed, we encourage everyone to carefully consider their room size when picking a mattress to make sure it fits their space nicely.
