A Twin XL mattress measures 38 inches wide and 80 inches long, and a Full bed mattress measures 54 inches wide and 75 inches long.

For larger teenagers, or young adult couples, a Full size mattress may be the better option.

Great For Growing Children

Bed Dimensions: Know about Twin, Queen, and King Bed

Twin beds are ideal for kids of all ages. When young children outgrow their crib mattress or toddler bed, they may not be quite ready for a full size bed. Plus, their bedroom may not accommodate a larger bed or it may take up too much living space.

Twin beds are the perfect size for any childs room. This size allows kids to sleep comfortably in a more spacious bed. Plus, a twin bed wont encroach on their play area or the available living space in their bedroom. If you have two children that share a room, two twins will leave extra space in the room, so kids wont feel cramped.

Older children may start to feel confined when sleeping on a twin bed. Throughout their teen years, kids may prefer a mattress that offers them a bit more space spread out and more leg room as they grow. In this case, a full or queen size bed may be the best option. However, if these mattresses are too big for their bedroom, you can opt for a twin XL. Twin XL mattresses are particularly helpful for taller teens since they are 5 inches longer than a regular twin.

Queen Size Mattress & Dimensions

Queen mattresses measure 60 x 80. Queen mattresses are wider and longer than a full-size mattress. A queen mattress is great for a single person who really likes that extra space and can fit it in his/her bedroom. Its also a big enough mattress for most couples.

The only reason to step up from a queen is if your bedroom is big enough to handle something larger or if you just really want the extra surface area to sleep on.

Is Twin Xl The Same As Full

Although a twin XL is 15 inches narrower than a full, itâs 5 inches longer. Twin XL beds usually canât comfortably accommodate more than one person, but they are an ideal choice for a single sleeper thatâs too tall for a traditional size bed. Twin XL beds are great for small, narrow bedrooms where thereâs not a lot of floor space, and are often the bed of choice for college dorm rooms and apartments.

The Full is also known as a Double. Unfortunately though the term Double doesnt quite suit this size because 54 divided by two is 27 of space per person, which is not much at all when sharing. The Full size, however, is an excellent option for single use. Like other mattresses of a similar length, this one would best suit someone under 6ft.

How To Pick The Right Mattress Size For You

Standard Mattress Sizes Chart

There are several factors you have to consider when it comes to picking the right bed for your needs. If you’re in the market for a new bed, here are a few of the questions you should ask yourself first.

How Big Is Your Room?

The first thing you think about when you’re getting ready to buy a new mattress is the size of your room. It doesn’t matter if you want a Queen or King bed. If your room is too small, you might have to settle for a Double bed instead.

Take the time to measure your room before you do any shopping.

How Tall Are You?

If you’re a tall person, consider investing in a longer-than-average mattress. This might mean you buy a Double XL or a Queen.

You should also think about your weight.

Bigger people will benefit from larger mattresses. Not only do they offer more support, but they also give you more space to spread out and get comfortable.

What Is Your Sleep Style?

Do you wake up in the same position you fall asleep in? Do you toss and turn the entire night? Do you sleep in a curled up ball? Do you spread across the entire bed?

If you don’t take up a lot of space when you sleep, you might like the cozy feel of a Double bed. But if you need room to move around, you might want to invest in a Queen, especially if you’re sharing the bed.

How Many People Will Be Sleeping in the Bed?

You probably won’t need anything bigger than a Double or a Queen mattress if you’re sleeping by yourself.

What Stage of Life Are You In?

It’s also harder to relocate large beds.

Whats The Most Popular Mattress Size

The most popular mattress size is the queen, which measures 60 inches wide and 80 inches long.

Its not as expensive as a king or California king mattress, but still offers more room than a full mattress.

Full Size Mattress Dimensions

Full size mattresses are usually a go-to choice for most individuals it offers more room than a twin, but its not as large as a queen so that it can fit in smaller rooms. These beds are perfect for those who dont share their mattress and should provide enough space to sleep comfortably.

When it comes to couples, or even those who often find themselves sharing their bed with their pet, a full or double bed may not have enough space to allow you to sleep comfortably. If you share your bed, we would recommend looking for a larger size. Simply put, full mattresses are good for one person.

Even More Mattress Sizes

What are mattress sizes & what size sheets do I need?

Weve covered the standard sizes and a few of the less common ones, but this still isnt all the potential sizes that a shopper has to consider. Its possible to buy an oversized mattress or another bed with custom dimensions from a specialty mattress manufacturer. For example, some of the biggest bed sizes include the Texas king, Wyoming king, and Alaskan sizes, all of which are far larger than the standard king.

For most people, a custom mattress isnt a necessity. However, there are circumstances when one can come in handy. Still, the difficulty of ordering not only a custom mattress but also suitable bedding and other accessories keep many shoppers from purchasing one.

What Foundation Can You Pair With A Thick Mattress

Thicker mattresses don’t have more complicated foundation needs than their thinner counterparts. You can use a conventional box spring or a platform bed. Adjustable bases are an option as well for some thicker mattresses, but seek the manufacturer’s advice on whether the combination will work. Some thick mattresses are not compatible with adjustable bases, as they aren’t able to flex.

The critical thing is to consider the total height of your bed setup. Pairing a thick mattress with a high foundation may make it difficult to get in and out of bed. The average height of a mattress plus foundation and frame is around 25 inches, though it can be more or less depending on your height and personal preference. Mattress foundations are available in standard height or “low profile” . You can mix and match the thickness of the mattress and foundation to get the setup you like best.

Here’s an easy way to tell if your bed height is right for you: When you sit at the edge of your bed, your feet should touch the floor comfortably and your knees should be level with your hips.

How To Choose A Mattress Size

The tables in the mattress size guide above give you the basic differences between the various mattress sizes. Before choosing, however, there are a variety of factors that you should consider:

Sleeping Partners Who do you share a bed with? This is the single largest consideration to keep in mind. Couples will likely want at least a queen, while couples sharing a bed with children will likely want a king mattress. Even pets are a consideration if you let your animals sleep at the foot of your bed, having a bed with ample legroom will greatly improve your comfort.

Your Height & Sleep Position How tall are you and/or your partner? Typically those under 6 feet tall will have enough legroom on any mattress, while those over 6 feet tall will want to consider a bed with at least 80 inches of length . Your sleep position also factors into this consideration back and stomach sleepers rest fully extended, and therefore need to consider legroom more than side sleepers.

Bedroom Dimensions What room will you put your new mattress in, and how spacious is that room? To avoid a cramped feeling, we recommend leaving about 24 inches of space around each side of your bed. Its best to measure out the approximate measurements of your new bed before purchasing it, to get an idea of how well it will fit in your bedroom.
