Do You Know Mattress Sizes?

Intro

Does mattress size matter? They most certainly do! Before buying a new mattress, be sure to know the dimensions of your room first. You don't want to get a Queen sized bed then realize last minute it doesn't fit. Also, having a sleep partner will determine what size you need, too. You might need the extra room, but your partner might want something else. Your height is another factor to consider. If you get the wrong mattress length, your feet will dangle off the edge.

It may seem complicated to think about at first, but don't be overwhelmed by the choices in front of you. Mattresses come in all sizes because people are unique in their preferences and standards for sleep. With just a little effort, however, we can help you pick the best size for you and your family.

Mattress Sizes

King and Queen sizes are usually the best mattresses for families. Twin and Full sizes are best for single sleepers and children/teenagers. Keep our considerations in mind as you read on. The most common mattress types are available in the sizes you'll read about.

Twin

Dimensions: 39" X 75"

Sometimes called a Single.

Great for young kids and some adults. You can also fit two of these beds in one room, hence the name "twin". The average adult will find it small, however. Its width measures just over three feet, leaving little room to move and spread out. They're popular in college dorm rooms and guest rooms due to their affordability and small size.

Twin XL

Dimensions: 39" X 80"

This is basically an upgrade from a normal twin, adding another 5 inches to its length to accommodate those tall teenagers. Although they give better leg room, their width size is still the same. A Twin XL has the same length as a King and Queen, but we don't recommend this size for those sleeping with a partner. When two Twin XL beds are combined, its called a "split king" mattress. This is useful for an adjustable base when sleep partners have different needs, such as for medical necessities (i.e. back aches and snoring).



When upgrading from a Twin to an XL, be sure to swap your foundations. The XL won't fit on a Twin foundation, unless the warranty specifically says it does.

Full

Dimensions: 54" X 75"

Also known as a Standard, Regular, or Double bed.

This mattress size is very versatile, being in between a normal Twin and a Queen sized bed. Its length is the same as a Twin, but its width is longer, allowing a single sleeper to stretch his arms a bit. The dimensions are still not big enough to accommodate a sleep partner, but big enough for pets or extra pillows. This mattress size is also great for a guest room, granted if you have the space. A Full mattress is easily movable and cheap, making it the economical choice for both money and space.

Full XL

Dimensions: 54" X 80"

Also the Double XL.

The Full XL offers an extra 5 inches to its length, which is great for tall sleepers. If width space isn't a priority, then a single sleeper will find what they need with this mattress size. Full XL's are uncommon on the market, but some retailers offer them. If you have an XL, double-check the accessories and foundation to see if they fit this size.

Queen

Dimensions: 60" X 80"

This is the most common and popular choice among mattress shoppers. The Queen is a nominal upgrade from a Full sized mattress, giving that extra room for you and your sleep partner. This size also attracts single sleepers for its large surface area, especially for those who prefer a lot of space when they sleep. The Queen size is perfect for master bedrooms and is moderately affordable to buy.

King

Dimensions: 76" X 80"

This behemoth of a mattress offers a lot of space, even for two people. One average adult could be dwarfed by the amount of room this mattress size offers. To put it in perspective, a King sized bed is like two Twin beds put together (albeit two inches shorter). The King has 16 inches more width than the Queen, giving space for children or pets. However, its size can make it difficult to move. It is also not recommended for small rooms, for obvious reasons.

California King

Dimensions: 72" X 84"

Just as big as a King mattress, but 4 inches added to its length instead of it's width. The California King is great for sleepers who are tall (6 feet plus). This is an excellent bed for sleep partners, providing a luxurious space that can't be passed up. Its shorter width allows it to fit in smaller rooms than a normal King mattress. In some areas, it could be difficult to find mattress accessories since its considered a unique size. Your best bet is to find accessories online if your local store doesn't have what you need.

Size factors

We provide four factors for you to consider when looking for a mattress size. Read through them and remember them when you're perusing around the store or internet.

1. Room space

Before buying a new mattress, measure the dimensions of your room first. You want to make sure you have room to accommodate that big mattress of yours. It's also a good idea to leave room around your mattress so you can move around a bit. If you have trouble just getting to one side of the room because of your mattress, then you have the wrong size.

2. Your height

Next to room size, your height might be the biggest factor to consider. If you're taller than 6 feet, you'll need a mattress length of at least 80 inches. Otherwise, your feet will hang over the bed. If you sleep with a partner, then go with whoever is tallest. Not only will that be comfortable for the taller person, but the shorter person will enjoy a lengthier surface.

3. Sleep partner

Speaking of your significant other, choosing a mattress size to accommodate both of you is going to be the utmost importance. You need a mattress size than can fit both of your comfortably without overlapping onto each other's side (unless you like to cuddle). The minimum width you need would be 60 inches, which is Queen size. If you don't care for the room, then a Full could be what you're looking for, just be prepared to cuddle.

4. Your Budget

The bigger the size, the more money you'll spend. Remember that when searching for a new mattress. If you really need the space, then the Queen size mattress will give you the best bang for your buck. According to Statista, nearly half of all Americans sleep on a Queen. If you sleep alone and need to save room (and money), then a Full mattress is affordably priced. Twin beds are smaller and therefore cheaper and can save a lot of room. A King and above are usually the more expensive mattresses, depending on the mattress type.

Do you know what size you need?

Hopefully, you're prepared to pick the right size for you and your family. Remember, Twins and a Full Mattress are great for children/teenagers. Some adults might find them a bit small, but they're affordable and can easily save you space. King and Queen mattresses are your go-to for those who sleep with partners. They're more expensive than the smaller sizes, but the luxurious space gives plenty of room for children and pets to sleep with.

Keep in mind the four factors we provided to you. Before buying a mattress, make sure you have the room to accommodate your chosen size. Consider your height so your feet don't dangle over the edge. Think about your sleep partner and come to a compromise on what you both prefer. Finally, be sure you know how much you're spending on a mattress. Follow the tips we gave you and you'll find what you're look for!
