Choosing the correct size mattress is important for creating a comfortable sleep environment. 

Twin, full, and queen size mattresses all have their place in the homes of consumers. Which mattress size you choose depends on your body size, room size, personal space preferences, and whether you’ll be co-sleeping with anyone. 

Twin mattresses are the narrowest of this group of mattress sizes. Stepping up to a full size mattress adds 12 inches of width to your bed while keeping the height the same. Going with a queen mattress expands both the length and width of your sleeping space. 

In this article, we’ll break down the different mattress sizes and assist you in picking the right size for your needs. We are going to discuss other mattress sizes, as well as the different types of mattresses available. To conclude, we’ll answer some of your mattress-related questions.

What is a Twin Mattress?

A twin size mattress is ideal for single sleepers, children, and teenagers. This mattress is long enough that most single average size sleepers won’t feel cramped or need extra legroom. The dimensions of a twin size mattress are 38 inches by 75 inches. 

According to the “2-foot rule,” you should have at least 2 feet of open space around your bed. This allows for better mobility and lowers the risk of falling in the middle of the night. Therefore, a twin mattress should be in a room measuring at least 7 feet by 10 feet. 

Pros

There are many reasons why a twin size mattress is a great choice. The first is its versatility to accommodate a wide age range of sleepers. You can buy a twin size bed for your child and won’t have to worry about them outgrowing it for several years.

The compact design of a twin bed is another big selling point. If you live in a studio apartment or have a smaller bedroom, this bed will be a perfect fit. Twin mattresses are also lightweight and easy to move when rearranging. Twin beds cost between $100 and $1800 on average. They are the cheapest of the three mattress sizes being discussed in this article.. 

Cons

There aren’t a whole lot of downsides to investing in a twin size mattress. The only issue some sleepers have is a twin isn’t wide or long enough to accommodate their frames. Furthermore, a twin will only be able to hold one person versus the two people full and queen size beds can fit. 

What is a Full Mattress?

Full mattresses are the best choice for shoppers whose needs cannot quite be met by a twin size mattress. This much wider mattress offers more room for you to comfortably change sleep positions throughout the night. Full size mattress dimensions are 54 inches by 75 inches. 

Per the 2-foot rule, you need to place your full size mattress in a room measuring at least 9 feet 6 inches by 10 feet 6 inches. This ensures you have plenty of walking space and room for other furniture. 

Pros

A full mattress is a good choice for sleepers who prefer a more spacious sleep environment. With this size bed, you’ll have room for one adult plus one child. Full size beds can easily accommodate several small children.

Cons

Full beds do cost quite a bit more than twin beds. When shopping for this size mattress, you can expect to spend $250 to $2500 on average. One drawback of full mattresses is they don’t have enough room to comfortably sleep two adults. While this is true for most couples, if both are smaller framed and lightweight, they may have enough room for both to sleep in a full bed. 

Queen Mattress

Couples or those who plan to co-sleep with more than one of their children should go with a queen mattress. The extra length and width this bed offers ensures you’re able to get a restful night’s sleep without disturbing your sleep mates. 

The dimensions of a queen mattress are 60 inches by 80 inches. Due to their larger size, queen beds need to be in rooms at least 10 feet by 10 feet. 

Pros

Many opt for a queen bed because it offers ample room for co-sleeping and to accommodate larger frames. Single sleepers enjoy the extra room a queen bed offers, with plenty of room to stretch out while resting or watching TV. 

Cons

There are few drawbacks to be aware of when buying a queen mattress. The first is that these beds are much heavier than the other two smaller mattresses mentioned. This may require you to have assistance when installing, moving, or disposing of your mattress. A bed this size also comes with a higher price range of $600 to $3000. 

Additional Mattress Sizes

For those whose sleep and space needs aren’t met by the aforementioned mattress sizes, there are plenty of other sizes out there. Here are three other common sizes to look into when shopping for a new mattress. 

Twin XL

The twin XL mattress is a fantastic solution for sleepers who need a little extra leg room but don’t want to jump up to a full size mattress. A twin XL bed measures 38 inches by 80 inches. Place this mattress in a room that measures at least 9 feet 6 inches by 10 feet 6 inches. 

King

Tall or larger framed couples usually find king beds provide them with just the right amount of space. King beds are also suitable for a master bedroom, guest room, or those who plan to co-sleep with several of their small children. 

King mattress dimensions are 76 inches by 80 inches. It is best to place your king-size bed in a room at least 12 feet by 12 feet. 

California King

The California king size mattress is for sleepers who want both extra space and length. While Cal kings are narrower than a standard king, the California king offers 4 extra inches of legroom to accommodate taller sleepers. 

California king beds measure 72 inches by 84 inches in size. These mattress dimensions require a room that measures at least 12 feet by 12 feet. 

Which is the Best Mattress Type?

Once you decide on a mattress size, you’ll need to pick a mattress type. The type of mattress you choose impacts your support and comfort levels. Here are four of the most popular types of mattresses. 

Innerspring

Innerspring mattresses are a staple in many households. They have a history of providing sleepers with bouncy support via coils and springs. When you choose this mattress type, you won’t have to worry about battling nighttime sweats.

Some sleepers report not getting enough support from an innerspring mattress. This can lead to sore joints and muscles. Another downfall of this older mattress type is that it has issues with sagging. You may also have issues with squeaking or creaking when rolling over in bed. 

Hybrid

The hybrid mattress is an all-around fantastic choice for sleepers who are stuck between choosing a latex and a memory foam mattress. A hybrid bed provides you with ample bounce, tension release, and plenty of support. 

Hybrid mattresses are more expensive and heavier. This can lead to issues when installing and disposing of your mattress. 

Latex

The responsive design of a latex mattress prevents sagging and makes it easier for those with mobility issues to get out of bed. The bouncy design of a latex bed is appealing to those who want lifted support from their bed. 

The natural manufacturing processing of latex mattresses makes them slightly more expensive than a typical mattress. However, this natural process means that your bed is better for the environment and allergy-friendly. 

Memory Foam

Memory foam mattresses are known for their body contouring and hug-like support. Those with joint or muscle aches can find soothing relief from this type of mattress. The motion isolation of a memory foam bed enables you to alternate sleep positions without waking your partner. 

Those who are prone to overheating or night sweats should invest in a memory foam mattress with cooling gel. This better regulates your temperature all night long for a more comfortable night’s sleep. Like latex mattresses, memory foam beds are more expensive than innerspring beds.. 

Mattress Shopping Factors

There are several different factors you’ll need to consider when shopping for a mattress. The size of your bedroom is chief among these factors. You should not try to squeeze a mattress plus bed frame and foundation into a room that is too small. This leads to mobility issues and gives your room a closed-off feeling. 

The number of sleepers is relevant too. Are you going to share your bed with a partner or your small children? Keep in mind the sizes of all people who are going to be regularly sleeping in the bed. 

Consider any health conditions and sleep disorders as well. These factors play a huge role in the type of sleep environment you need to sleep soundly and pain-free throughout the night. Finally, consider your budget. How much are you willing to spend and how flexible can you afford to be?

FAQs

What size bed should I get for my height?

Choosing a bed size right for your height is crucial for ensuring you have enough legroom to sleep comfortably and avoid feeling cramped. Sleepers of average height can get by with a Twin or Twin XL size mattress. 

Taller and larger sleepers need to opt for a full or queen mattress. These longer and wider mattress sizes are better for the long limbs of these individuals. Be sure to keep the height of your partner in mind when choosing a mattress size. 

Are full and double beds the same?

Full and double beds are the same size. A full or double bed measures 54 inches by 75 inches. A mattress of this size can easily sleep one adult and one child. Full mattresses are the perfect option for those who are stuck between choosing a twin and queen size bed. You’ll need to put this bed in a room that measures at least 9 feet 6 inches by 10 feet 6 inches. 

Is there a mattress smaller than a twin?

If you’re shopping for a mattress that is smaller than a twin, you’ll want to go with a small single. This mattress is great for small kids and toddlers. Small single beds measure 30 inches by 75 inches. In contrast, a twin mattress measures 38 inches by 75 inches. 

Do two twins equal a queen?

Two twin mattresses do not equal a queen size mattress. The twin mattresses are too wide and too short to fairly compare them in size to a queen bed. Consequently, you won’t be able to use queen size bedding if you choose to put two twin mattresses together. However, you can put two twin XL mattresses together to equal the size of one king bed. 

Can you use full sheets on a twin bed?

When possible, your sheet size should correspond with your mattress size. This ensures your bedding accessories fit properly and avoids slipping or bunching. In a pinch, you could use full sheets on a twin mattress. You may need to use sheet fasteners or straps to keep the sheets snug. 

Conclusion

Twin, full, and queen mattresses can all provide you with a restful night of sleep. Which size mattress you decide to buy depends on your room size, body type, and the number of sleepers who use your bed at once. The type of mattress you buy is important as well. For this buying decision, you’ll want to factor in body type, sleep position, and support needs.
