Mattress Sizes & Dimensions Guide

Mattress sizes are important in determining the best mattress for you. There are a lot of things to consider – the size of your room, if you’re sleeping with a partner or if you’re co-sleeping with kids and the purpose of the mattress, as well (like is it for your guest bedroom? is it for your kids’ room?). Your weight and height is also a big factor – as some mattresses may not be thick enough for heavyset sleepers. All these (and more!) are what you need to consider when choosing a mattress size.

What Are the Standard Mattress Sizes and What is It Best for?

sizesOne common thing people forget when getting a mattress is the size. 

Most of the time, people are so used to focusing on the bed’s comfort, its sleep technology, its components, and you know everything else aside from the bed size.

 

 Did you know that a mattress size is an essential factor in getting yourself a bed?

Although choosing one for yourself won’t be easy, there are a lot of sizes that are very much available for you.

You should understand that getting one’s mattress size is an individual preference, but getting to know its dimensions and its specifications will help you understand what it’s best for.

The specific mattress size we choose will also depend on the following factors:

We’ll talk more about this later.

The ultimate goal every night is to have a good night’s sleep. This guide will make sure you’ll get yours through choosing your perfect mattress size.

Let’s check out all the available mattress sizes and what it’s best for.

Small Single Size Mattress

Let’s start with the small single size mattress. The Small Single Size Mattress measures 30 inches by 75 inches.

Having this mattress would need a room size of 7 feet by 10 feet. This bed is perfect for young couples who are just beginning to have a family of their own.

Why?

This mattress size is perfect for babies and toddlers, and can also be used as crib mattresses if preferred.

Crib Size Mattresses

Just like the small single-size mattress, this can also be the perfect bed that will fit your baby’s needs.

This can be your baby’s first bed.

Measuring 27″ x 52″, the standard size is accepted to fit any standard crib you can bring home once your little bundle of joy finally arrives. 

But note that crib mattresses are made to be firmer than regular beds, so there is nothing for you to worry about or doubt about your newborn baby’s safety using this mattress. And of course just like adult mattresses, the foam and innerspring of these crib mattresses depends upon preference,

You can choose between mattresses that are lighter for portability or beds that are easier to clean.

These kinds of mattresses usually fit your baby until toddlerhood. 

Twin Size Mattresses

A twin size mattress measures 38″ x 75″.These are the kinds of beds that children usually sleep through their childhood.

The good thing about this bed is that even while a child is transitioning from childhood to adolescence, this bed will still fit perfectly. The sleeping space for this bed is perfect for solo sleepers.

These mattresses are usually slim in size, which makes them pretty easy to fit side-by-side in any kid’s room and can also be used as bunk beds.

These beds can also work well with smaller guest bedrooms in your homes, or even in really odd-shaped spaces.

Note that this bed size can also be suitable for solo sleeping adults living in small spaces, just like condominium units.

Twin XL Size Mattresses

Twin XL Size Mattresses are measured 39″ 80″.

These beds are the standard sizes used in college dorms. Naturally, these beds were made to save space, so they do not offer anything with a bigger width. But, Twin XL Beds provide taller sleeping spaces if you prefer to give you the extra legroom you need.

This makes this bed very versatile. The best thing about Twin XL Mattresses is that because of its size, it’s easy to move it from one place to another. 

But of course, aside from just college dorms, this mattress is perfect for adult solo sleepers and those who are sleeping in minimal spaces.

Full-Size Mattresses

Full sizes are considered the next level of twin beds, as it measures 54″ x 75″. Since it still offers a pretty good amount of space, this is always perfect for single sleepers.

However, this size is still not perfect for couples since each still gives them minimal space.

The good thing about this bed size is that it’s in between a Twin sized bed and a Queen sized bed. These beds are perfect for:

This is why this mattress is also called the “starter mattresses.” Full-Size Mattresses can also be perfect for guest rooms.

Queen Size Mattresses

Queen Size Mattresses measure 60″ x 80″ and probably are the most popular bed size.

Why?

It’s because these versatile size mattresses are a perfect size for couples, giving them enough personal sleeping space.

These mattresses can still fit limited size bedrooms. Regardless of whether you are a single sleeper or sleeping with a partner in your bed, trust me, a queen-sized bed is not something you would outgrow.

Most of the master bedrooms can comfortably accommodate queen size beds, which makes the mattress size just about right. 

Because of a Queen Size Bed’s popularity, it has a lot of available accessories and even beddings that vary in style, price, and materials too.

Olympic Queen Size Mattresses

Olympic Queen Size Mattresses are measured 66″ x 80″.

This is suitable for rooms measuring 10 feet x 10 feet. These mattresses are also considered to be the standard size for couples, 

The good thing about Olympic Queen Size Mattresses is that it provides you just a little more space than the Queen Size, although not as big as a King Size.

But if ever you’re looking for a suitable space for sleepers, this bed will still give you a good deal.

King Size Mattresses

Offering a luxury of space, a King Size Mattress measures 76″ x 80″. The good thing about this mattress is that it is perfect for couples and does not compromise the space for each.

Now, couples can have more spaces for themselves, more than what Queen Size Mattresses can offer.

To visualize it, King Size Mattresses make it feel like each one on the bed can get a Twin Size Bed of their own.

These beds can ideally be shared with young children or even pets.

California King Size Mattresses

Last but not least, we have the California King Size Mattresses that measure 72″ x 84, which is the most extended mattress on the market.

This bed size is perfect for tall sleepers who need very long mattresses with extra 6″ in length and 12″ in width, more than what queen-sized mattresses offer to be able to sleep comfortably.

Now, tall people don’t need to worry about hanging their feet at the edge of a bed anymore. 

Because of its very wealthy space, it fits perfectly to be shared by couples, couples with kids, or even couples with pets, offering them a lot of extra space while sleeping.

How Do I Choose The Perfect Bed Size For Me?

As mentioned, choosing the perfect bed size for you is not just for the sake of choosing. Since buying a mattress is seen to be quite a long time investment, you just have to do your research.

Over-all, you must consider several factors before being able to take your pick. Considering these factors will help you find the perfect mattress size for you.

Remember, buying a mattress is never a one-size-fits-all, so you must consider your individual needs when it comes to this.

Here are some of the factors you need to check on before buying your mattress:

People Sleeping On The Bed

First thing’s first. When buying a mattress and choosing its size, you must first consider who you are sleeping in the bed with.

It might be you’re sleeping with:

Or, you may just be a solo sleeper yourself. Usually, Queen, King, and California King Size Beds are the ones perfect for sleeping with partners while having a Twin, Twin XL, or even a Full-Size Mattress is ideal for single occupancy.

By any chance you’re also sleeping with someone on the bed, you should also consider your sleeping positions just for you to estimate enough bed space you need when sleeping.

The Size Of Your Room

One more thing you need to consider when buying a mattress is your room space. 

Why so?

A room space would profoundly affect if your mattress size will fit your bedroom or not. And, we don’t want to experience any hassle on that part, do we?

Also, keep in mind that your bed is not the only thing that’s inside your room. To ensure a more comfortable space for your bedroom, you must also consider the other accessories in your bedroom, such as your mirror, your closet, etc.

The Location Of Your Room

Is your room located on the first floor?

Or is it on the lowest floor of your house?

This is something you also must consider: it may be quite hard to maneuver bigger beds or merely fit them in staircases if they’re quite big like California King Beds.

Your Body Size

Another thing you should consider when choosing your mattress size is your body size.

Take your height and even your weight as a consideration when choosing one. Let’s say that a Twin Size Bed measures 75 inches tall while a twin XL is 80 inches tall. By any chance you are taller than six feet two inches, then a twin mattress would not be perfect for you.

But if you are taller than 7 feet, then a California King Bed would be perfect for you so you can get more stretching space.

Your Budget

Last but not least, another thing you should consider when getting a mattress is your budget.

The amount of money you decide to spend will significantly affect which mattress you would most likely get since bigger mattress sizes will cost more.

If you’re working on a specific budget, then you might opt for smaller mattresses then. You must be able to have a realistic budget for yourself. In doing so, you can check out mattress materials, brands, and even brand reviews to help you with your personal choice.

This will help you meet both size and financial needs.

The Pros And The Cons

There are a lot of advantages and disadvantages when it comes to choosing your mattress sizes.

For its advantages, choosing the perfect mattress size will help you consider the space you need to be able to sleep comfortably while considering the people you are sleeping within your bed.

It may be with your partner, your children, or even your pets.

The downside of it is that choosing a mattress size isn’t just a walk in the park because it can be quite a hassle.

You need to consider:

And considering, you have to integrate all these factors for you to come up with the perfect decision for your chosen mattress.

And that is quite a lot of factors we’ve got right there.

The Takeaway

Overall, choosing your bed’s comfort (firmness and type) is just as important as deciding your mattress size to achieve 100% comfortability of your bed.

When choosing, you must consider the other factors such as who you are sleeping with on the bed, room space, and even budget so you can finally come up with the perfect mattress size for you.
