Twin vs. Single Bed Size: How Do They Compare?

Lots of people seem to be wondering about the differencebetween the single and the twin bed.

It’s obvious that sizing is one of the most important consideration when choosing a mattress, so let’s have a closer look and identify the difference between those two commonly mistaken types.

How Big is a Single?

A single bed is 39 inches wide and 75 inches long. Its main designation is to fit one person. Obviously, this is where the name “single bed” stems from. These are comfortable and convenient for kid’s rooms and are likely going to be suited for the kid until he hits high-school age as the 75 inches might not be enough at that point. It’s one of the most preferred options when it comes to furnishing children’s rooms.

How Big is a Twin?

The twin measurements are practically identical to the single. However, it is intended to be one of a pair of single beds. They are usually put in guest rooms which would be shared by more than just one person. They are also commonly chosen by couples who prefer to sleep together but not to share their bed as they don’t feel comfortable.

It’s also important to note that there are a few different variations of the twin size bed and the most popular one of them is the Twin XL.

Twin XL

There is just one difference between the regular Twin and the Twin XL. The latter comes with added 5 inches in length, making it suited for college kids and people who are slightly taller.

Who Should Own a Single?

A single bed is usually placed in a kid’s room. They are also quite perfect for hotels in rooms which are designed to sleep, three people. These are the so-called “triple” rooms and are very characteristic for low-budget hotels and motels as they are far more affordable and yet they don’t compromise your sleeping comfort.

Additionally, single mattresses are preferred if you have a smaller guest room and can’t afford to place a larger sized unit.

Who Should Own a Twin?

Twin beds are designed to go in matching pairs, as we already explained above. The most common application for them is the regular double room in a hotel. A lot of hotels use this instead of a common king-sized or regular two single in order to accommodate the versatile demand of clients who are single and those who are a couple.

Additionally, a twin mattress, as we mentioned above, are preferred for rooms which have to be shared by siblings, for example.

Conclusion

There is obviously no difference in the single and twin measurements, but the intention and purpose of both beds are completely different. This is something that you’d have to account for when you’re making the call. Take the aforementioned into account in order to ensure that everything is handled perfectly.

Double Bed Size and Dimensions: How Big Is A Double Bed?

September 27, 2019 Author: Jesse Tutt

Double Bed Size

About 35% of people don’t get enough sleep. That’s 1 in 3. IS THAT YOU?

For some, this might be due to bad habits. But for many, it all comes down to the quality of your mattress. For example, you’ll probably have a hard time getting to sleep if your bed is too small or full of painful springs.

If this sounds like you, a new mattress might be enough to improve your sleep.

But before you go shopping, you need to understand the size of a double bed or double bed size and dimensions. That’s why we’ve put together this guide to help you find the right size bed for your needs. You can also check out our complete up to date Bed Sizes Canada guide!

So let’s get started!

What Is a Double Bed?

A double bed is the standard size for single sleepers.

In other words, it’s bigger than a twin mattress and even a twin XL mattress but smaller than a queen. Double beds offer more flexibility in terms of users and spatial arrangements and have become one of the most common bed types.

But why is this bed called a double bed when it’s designed for single sleepers?

Well, youcanfit two people on a Double bed. However, many people sharing their bed with someone else want a little more space to spread out. Because of this, most couples have queen beds instead.

But don’t let the Double bed’s name throw you off.

A Double bed is also called a Full bed. Many people use the two names interchangeably. So if you fo shopping for a Double bed but can’t find one in the store, look for a Full bed instead.

Though the names are different, Double and Full beds are the same size.

What Size Is a Double Bed?

This might seem like a simple question, but it doesn’t have a simple answer.

Because the size double bed technically includes every mattress that can fit more than one person. When you ask what size a Double bed is, you have a lot of different mattress types to go through, including Queen and King.

But don’t panic. We’ve put together a helpful list of the different sizes of a Double bed below.

Double Bed Dimensions

Understanding the Different Dimensions of a Double Bed

When it comes to bed sizes, there are more than just double, queen, and king. You should understand these mattress dimensions before you pick one for your home.

Double Bed Sizes In Inches

Here’s a quick rundown of what you need to know for double bed sizes in terms of Inches:

1. Standard Double Bed

The average size of a standard Double bed is 54 inches wide and 75 inches long.

Who Can Sleep in This Bed?

Again, this bed size can fit two people, but it’s a tight fit.

That’s why this bed has become the standard size for single sleepers. The bed has plenty of space to spread out and enough space left over for a child or pet. It’s also a good option for teenagers who have outgrown their Twin mattresses and need a little more space.

Since you can fit more than one person on this mattress, it can also serve as a guest bed.

2. Double XL

This bed has the same width as a standard Double mattress, but it’s about five inches longer. In other words, Double XL mattress dimensions are 54 inches by 80 inches.

Who Can Sleep in This Bed?

A Double XL bed is designed for tall people who need a little bit more space than a standard Double bed can give them. It’s also a good choice for people who want a bigger bed but don’t have quite enough space for a Queen size.

3. Queen

Just as a Double bed is the standard size for one sleeper, a Queen bed is the standard size for two sleepers. It’s much bigger than a Double bed with a width of 60 inches and a length of 80 inches.

Who Can Sleep in This Bed?

This bed can fit two people comfortably. Even if you move around in your sleep, you won’t bump into the other person sleeping with you.

A Queen bed can also fit into most modern bedrooms, so unless you’re tight for space, you shouldn’t have a problem buying a queen bed.

4. Queen RV

A Queen RV is a few inches shorter than a normal queen mattress. Because of this, it’s usually used in recreational vehicles. Instead of being a full 80 inches in length, this mattress is 75 inches long instead—but the width is still the same.

Who Can Sleep in This Bed?

Even though this bed is a bit shorter than a normal Queen, it still gives two people plenty of room.

If you’re looking for an RV mattress, you should stick with a Queen RV. You can also buy this mattress if you don’t have quite enough space for a full Queen.

5. Olympic Queen

An Olympic Queen mattress is the biggest type of Queen bed out there. It’s 66 inches wide and 80 inches long.

Who Can Sleep in This Bed?

Olympic Queens make a good alternative for King mattresses if you don’t have quite enough space. Two people and their two dogs could sleep on this bed without even touching each other.

6. King

The average size of a King mattress is 76 inches in width and 80 inches in length. This is one of the biggest mattresses you can find on the market.

Who Can Sleep in This Bed?

Before you decide to buy a king bed, you have to make sure your room is big enough to hold it. After all, this bed can sleep two adults and two children at the same time. You might even be able to squeeze a pet on, too.

7. California King

A California King is somewhat narrower than a traditional King bed. Instead of being 76 inches wide, it’s only 72 inches wide.

But it makes up for the loss in width when it comes to length. A California King mattress has an extra four inches in length, making it a total of 84 inches long.

Who Can Sleep in This Bed?

This mattress is good for tall people who want their fair share of space. Since the bed is narrower than a normal King, you might not be able to fit two children on the bed with you. However, you can sleep comfortably with two adults, one child, and a pet at your feet.

8. Texas King

A Texas King is the biggest mattress size out there. It’s a full 80 inches wide and 98 inches long.

Who Can Sleep in This Bed?

You have to have a pretty spacious room to fit this monster bed. But if you want something that’ll give you a lot of arm and legroom, this is the bed for you. You can practically fit a whole family on this bed.

Double Bed Sizes In Centimeters (cm)

Here’s a quick rundown of what you need to know for double bed sizes in terms of Inches:

Double Bed Mattress

Does Material affect the Size of a Double Bed?

It might surprise you to learn that the answer to this question is yes.

The mattress material can change the dimensions of the bed by a half-inch or so. So once you pick the mattress size you want, here’s what you need to consider the material.

Foam Mattress

Most foam mattresses match up to the size they’re advertised as. Foam mattresses are more flexible than coil mattresses, so you won’t have trouble stretching a sheet over each corner.

Coil Mattress

Coil mattresses, on the other hand, are a lot harder and sturdier than foam mattresses. Because of this, you might have trouble fitting a sheet over a Queen mattress that’s exactly 60 inches by 80 inches.

To make this job easier, your queen mattress might be 59 1/2 inches by 79 1/2 inches instead.

But don’t let the smaller size worry you. Every mattress must legally be within an inch of their advertised size. So if you buy a Queen mattress that’s advertised as 60 inches by 80 inches, the smallest it can be is 59 inches by 79 inches.

How to Pick the Right Mattress Size for You

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.

If you’re sharing the bed with another adult, you shouldn’t get anything smaller than a Queen. You might even want to get a King if you are both tall or move around a lot in your sleep.

People with young children should also consider buying a Queen or King-sized mattress. This will allow you to still get some sleep when your kids climb into your bed at night.

A Queen bed can fit two adults and one child if you’re okay with a tight squeeze. But if you have more than one kid who regularly climbs into your bed, you might want King.

What Stage of Life Are You In?

If you’re a young adult still living in your first apartment, you might want to stick to something small you can upgrade later. A Double bed or even a Twin XL might be the best option until you settle down in a permanent location.

It’s also harder to relocate large beds.

People who plan on moving might want to buy a Double bed as well. It’ll make the moving process easier and faster.

But if you’ve settled down in your own home, go as big as you can afford.

What’s Your Budget?

You shouldn’t go into debt for a mattress.

While a quality mattress is well worth the money, don’t buy something that’s out of your price range. If you want a King bed, take the time to save until you have the money to spend on it.

The most economical mattress is the Queen. So if you want the most bed for your buck, you should consider buying a Queen mattress.

Your Guide to Double Bed Sizes and Dimensions

Shopping for a new mattress is harder than picking something that looks comfortable. Before you think about the material, pick the right size first. Otherwise, you’ll end up with a bed that’s too small or much, much too big.

Mattress Size Chart And Dimensions

Use this mattress size chart to determine the size of the mattress that will suit your needs before you shop for your next mattress. If your mattress isn’t big enough for everyone who will sleep in your bed and any pets that join you, you won’t sleep as comfortably as you should. On the other hand, if your mattress is too big for your bedroom, you won’t have enough room for other furniture or to make the bed.

Mattress Sizes You Need

Use the mattress size chart to be sure about your requirements because some mattresses might not fit in your room, which can create a real hassle if you buy from a mattress store that doesn’t allow returns.

First, you should consider what size you need today as well as any changes you expect in the size you’ll need during the life of the mattress. For example:

  • If you’re single but you hope to marry in the next five or so years, you may want to consider purchasing a bed that will work after you’re married. This is especially true if you’re settled in your own home.
  • If you’re renting and likely to move frequently, consider the difficulty of moving a larger bed compared to moving a smaller bed and mattress.
  • If you’re buying a mattress for a child, remember how fast they grow. Many children will reach their full height in the bed you purchase to replace their toddler bed.

Custom Sizes

You may be surprised to learn that you canorder mattresses in custom sizes. Some beds or sleeping arrangements require custom sizes, including extra-long or extra-wide versions and custom shapes to fit specific needs.

Three factors are the most important when you choose the size of your mattress:

  • What size do you need?
  • Is the room large enough to accommodate the mattress you need?
  • Your budget

If you have a new bed, one of the standard mattress sizes will fit. If you have anantique or RV bed, you may need to order a custom size. If you are significantly larger than average, such as an NBA basketball player, you may want a custom bed to accommodate your height. The largest standard mattress length is seven feet. Most people don’t sleep with their head against the headboard. So, anyone who is 6’5” or taller may find a 7-foot length confining.

Room Size

We specify the minimum room size you need to accommodate mattresses for each type of mattress throughout this article.

Your Budget

Your budget should consider both the mattress purchase, the cost of the bed as well as the bedding, and the cost of providing a room large enough to accommodate the mattress. We illustrate the substantial price difference between choosing a King and Queen size below:

KingQueen
Nectar Mattress$899$699
Sheets$114$89
Mattress Protector$99$89
Platform Bed$275$250
Wool Blanket$180$150
Total Cost$1,567$1,277

Mattress, sheets, mattress protector, and platform bed prices are fromNectaron July 12, 2019. The wool blanket represents the average price difference we found after looking at several different options.

If you want a more traditional bed, like this Coastal Sleigh bed (pictured below), the King size is priced over $400 more than the Queen.

We won’t bore you with the math, but we calculated that building a home with a room large enough for the minimum King size mattress would cost $5,500 more than building a home with just the minimum size needed for a Queen mattress using an estimated $125 per square foot. For ideal comfort, you’d want more than the absolute minimum size if you have furniture other than the bed and night tables in the room.

Keep in mind that you’ll incur some of these expenses repeatedly. Most people have more than one set of sheets for their bed and everything except the bed itself will eventually wear out and need to be replaced.

If you need a King size, then go for it. But if you’re comparing the price of just the mattress and thinking “I might as well, it’s only $200” you’d overlook quite a few related expenses.

Keep in mind that some people also need their personal space while they sleep. If you need the space, choosing a mattress that is too small is penny wise and pound foolish because impairing the quality of sleep has long term negative implications for health, relationships, and even safety.

Therefore, we provide you with details on different sizes, their dimensions, their purpose, and who they suit best.

Crib Mattress Size

When it comes to the size of a crib mattress, the most important factor is that it fits snuggly in the crib. You do not want a gap between the mattress and the side of the crib as a gap can endanger your child. Standard crib mattresses are28⅝-inches in width and 52⅝-inches in length. Moreover, a crib mattress should not be more than 6-inches thick.

A crib mattress that is too thick puts your child at risk of being able to topple out of the crib. Crib mattresses will usually also fit in toddler beds, so they’ll last for the first several years of your child’s life.

Recommended Room Size

The minimum recommended room size for a nursery with a crib is 7-feet x 10-feet.

Note that experts recommend that babies sleep in the same room as their parents during at least the first six months of their life, but not in the same bed.

Twin Mattress Size

Most children sleep in a twin bed after they outgrow their crib or toddler bed. The twin-size is one of the most common sizes used for children. Because these mattresses are small, they leave enough space for toys and room to play.

The standard measurements for a twin bed in the USA are39-inches in width and 74-inches in length. Sizes in other countries vary slightly.

Bunk bedsusually use twin size mattresses, although some bunk beds combine a twin upper with a full or queen size lower bed.

A twin mattress is an ideal solution for people who share a single room but don’t share a bed. Some couples opt for single beds for a variety of reasons including reducing disruptions to one another’s sleep.

When considering the size of the mattress to purchase for your child, think about how tall your child is expected to be by the time the mattress wears out. Your pediatrician can give you an estimate.

If your child is expected to be tall, you may want to opt for a Twin XL although sheets will be somewhat more expensive, and Twin XL sheets tend to be more difficult to find in stores. It may be well worth the cost. A teenager who doesn’t sleep well because they are too tall for their bed is likely to be both grumpy and make worse decisions than they would if they were comfortable. Sleep deprivation has a negative effect on self-control and cognitive abilities.

Recommended Room Size

The minimum size room for a twin bed is 7-feet x 10-feet. For two twin beds in one room, the minimum size of the room should be 12-feet x 10-feet.

Twin XL Mattress Size

If you need extra length for your height, a twin XL bed provides it. This is also handy if your cat or dog tends to sleep on your feet.

Twin XL is the most common size used in college dorm rooms. Thedimensions are 39-inches x 80-inchesin the USA, which provides you with an extra 6-inches for your legs. Canada’s twin XL is almost the same size as the one in the US. Twin XL isn’t a standard size in the European Union or France. In the UK, the closest is their small double.

Recommended Room Size

The minimum room size for a twin XL bed is 7-feet x 10-feet.

Full Mattress Size

Full-sized beds are also known as double mattresses. Less expensive hotels often use them as a substitute for Queen beds. These mattresses are 16-inches bigger than a twin in width. The dimensions of full-sized mattresses are54-inches in width and 74-inches in length. These beds are equipped with enoughspace to accommodate two small individualscomfortably.

However, please bear in mind that your partner may not like the size of the bed if you tend to move around a lot in your sleep on a full-sized bed. Such mattresses are more useful for older kids who can have a sleepover without needing a second bed.

A full-sized mattress allows you to cuddle up with your kids if you regularly tuck your children in for the night. You’ll also be able to lay down with them while you read them a bedtime story.

Recommended Room Size

The minimum room size for a full-sized mattress is 10-feet x 12-feet.

Full XL Mattress Size

A full XL mattress equips you withadditional room for your feet. The dimensions of these beds are54-inches in width and 80-inches in lengthwhich means that you get an extra 6-inches to stretch your legs and feet.

Similar to full-sized beds, the full XL bed is an excellent option for tall individuals.

Nevertheless, these beds don’t provide you with extra width that you can enjoy in the Queen version. Full XL mattresses are a good choice for people who like to cuddle with their partners during sleep, and don’t care much about having their own space for sleeping.

This is not a common size and you may have difficulty finding sheets in this size in department stores. Fortunately, there are numerous options for sheets in this size when you shop online.

Recommended Room Size

Based on the walking space that you need in your room, the minimum recommended room size for a full XL mattress is 10-feet x 12-feet.

Queen Mattress Size

Queen beds are the most commonly used size in the world because they cater to the needs of most people. Queen size mattresses provide extra room which makes sleeping with a partner more comfortable for people who don’t want to touch someone else while they sleep. Standard Queen-sized mattresses are large enough to provide room for a couple of sleepers. Both people will enjoyenough space to enjoy their sleep and have room to rollover.

It also keeps you close enough that cuddlers can easily find one another. Standard queen-sized mattresses come with dimensions of60-inches in width and 80-inches in length. This bed offers more than enough sleeping space for single sleepers to move around during sleep.

You will also have room for your children or pets to sleep with you. Nevertheless, these mattresses are far bigger than other beds mentioned above, and for this, you need to have enough space in your room to accommodate these beds comfortably and still walk around with convenience.

This bed size is preferable for guest rooms, if you want couples to be comfortable. If you want them to go home quicker, choose a full-size.

Teenagers can spread out on a Queen-sized bed and have sleep overs without needing a second bed.

Many married couples opt for this size. If you’re sleeping alone, using a pillow to cuddle helps keep your body heat close to your body so you won’t feel too cold.

Recommended Room Size

The minimum size room recommended for a queen-sized mattress is10-feet x 10-feet. Keep in mind, this is a minimum and you’ll be more comfortable if you have more space.

Olympic Queen Mattress Size

Olympic queen-sized mattresses have dimensions of80-inches in length and 66-inches in width. They provide an additional 6-inches of width when compared to a standard Queen mattress.

The extra width is suitable for times whencouples need some personal spacewhen they are in bed and six additional inches helps with that. Olympic queen size also accommodates your child who needs some cuddling too if they wake up during the night, which is an added advantage of this size.

Olympic Queens are not a common size which means you won’t have as large of a selection of sheets to choose from when you purchase sheets.

You can use flat sheets for a king and tuck them under the mattress if you can’t find fitted sheets that match your décor.

Recommended Room Size

The minimum recommended size for a room with anOlympic queen mattressis 10-feet x 11-feet.

California Queen Size

You’ll see on the mattress size chart that the California queen-size has dimensions of60-inches in width and 84-inches in length, and it is the best option for couples who need some extra space for their feet or pets at the end of their bed. The width of a California Queen is the same as a standard Queen.

This size is the preferable choice for tall couples who don’t want a King-sized mattress. This size also provides extra room at the foot of the bed for your pets.

Note: Infants should not co-sleep as pictured in this image. They should be in a baby box, bassinette, or other safe sleeping space so they can’t be accidentally suffocated if one of their exhausted parents rolls over on them or the blankets cover their little nose.

Older children can safely co-sleep as pictured.

Recommended Room Size

The minimum size of the room for a California Queen is 12-feet x 10-feet.

Standard King Size Bed

A King-sized mattress is good forcouples who prefer a lot of spacewhile they sleep. It also gives them enough space for various other activities including stretching, relaxing for comfort, and rambunctious sex. The dimensions are76-inches in width and 80-inches in length.

These measurements make the bed as large as two twin XL mattresses joined together. The standard King is also the best size for couples who expect their child to share the bed with them on a regular basis and those who sleep with multiple or large pets.

Some people find a King-size mattress too big when they’re sleeping alone while others revel in having room to keep their favorite books on the bed.

The box spring versions of this size are split. They can be moved around very comfortably through tight corners and stairwells.

If you have an adjustable bed, you can opt to have a split king that allows both people to independently control the position of their side of the bed.

As noted above, infants should not co-sleep as pictured in this image. They should be in a baby box, bassinette, or other safe sleeping space so they can’t be accidentally suffocated. Older children can safely co-sleep as pictured.

Recommended Room Size

The recommended minimum room size for a standard King mattress is 10-feet x 12-feet although you’ll probably want more room.

The California King is the largest common mattress size of them all. An Alaskan King is even larger, measuring 108 inches (9-feet) in both directions. This size is the longest standard size. The California king-sized mattresses measure72-inches in width and 84-inches in length. This size is perfect forpeople who prefer more length but not extra width.

On the mattress size chart, you’ll notice it is 4-inches narrower than the standard king size mattress, but of course, you get additional 4-inches in bed length. Being smaller than the standard king bed, California king is still 6-inches broader than a queen bed. It provides you and your partner with enough room for sleeping space or to cuddle as per your convenience.

The option for California King is best for adjustable beds because elevating the bed affects the usable length. A California King sized mattress gives you plenty of room to do whatever you want on it including accommodating your children and pets who invade your bed. This size canconveniently accommodate a third personon the bed with ease.

Like a King, you can opt for a split California King for an adjustable bed.

Recommended Room Size

The minimum room size for this mattress is 12-feet x 12-feet.

Mattress Thickness

You might have noticed that we didn’t mention much about the thickness of the mattress. Well, it is because there are no standards when it comes to thickness and the options vary quite a bit. If you’re interested, you can check for more details from sleep educator terrycralle.com.

Some of them offer 9- to 10-inch thickness, but most of the pillow top beds have 15- to 16-inch depth or more (Like Dreamcloud mattress). Box springs raise the mattress even further from the ground.

When choosing the thickness of your mattress, there are a variety of things to consider.

Overall Height of the Mattress

The top of your mattress will be a combination of the height of the bed or platform plus the height of the mattress. If you will use a box spring, you have to also add the height of the box spring. Some beds are so tall you need steps to get into them. While this may look romantic, if you’re planning to have a baby, consider the difficulty of safely navigating the steps holding an infant who wants to nurse in the middle of the night when you’re exhausted.

Too much height can also be difficult for someone who has mobility issues.

However, a mattress that is too low to the ground can present other issues that make it difficult for someone with mobility issues to stand up from the bed. If mobility issues are a concern, you’ll want a total height close to that of most chairs which is about 20 – 22-inchs above the floor.

Thickness of the Mattress

Generally, the more you weigh, the thicker the mattress you’ll need not to bottom out. The minimum depth of a comfortable mattress varies by the types of materials used to make it. Innerspring and hybrid mattresses are generally thicker than latex or foam mattresses.

Bedding Should Consider the Height of the Mattress and the Bed

If you opt for a traditional bedspread that reaches the floor, the height of the entire bed needs to be considered. However, be aware that bedding that hangs to the floor is not recommended by bed bug experts.

Today, most people opt for a comforter that hangs to the bottom of the box spring.

You should also consider the height of your mattress when you buy sheets. If your mattress is only 10” thick and you buy sheets for beds with a 15” thickness, the fitted sheet may be loose and wrinkle underneath you. If you buy sheets for a 10” thick mattress and your mattress is 14” thick, you’ll have difficulties getting the sheets on and they will be more likely to come off.

Conclusion

You have many options. Evaluating your current and expected needs, space, and your budget will help you narrow your choice down to one or two. Otherwise, it is overwhelming.

Make sure you have space to walk around the bed. You don’t want the daily hassle of having to perform gymnastics just to make the bed. A mattress that is too big for the room makes it feel congested.

On the average, you will require aminimum of 30-inches between your bed and the wallfor a convenient path for walking around. Add sixty inches to the width on the mattress size chart and compare it to the measurements of your room. Some beds also come withdrawers underneath for additional storage space.If your bed has drawers, add more than sixty inches to the measurement on the mattress size chart. Because you won’t be able to access or use the drawers if your bed is placed too close to the wall.

So there it is, now you know all about different size mattresses that you can choose for your room. The mattress size chart includes all the common sizes in the USA, UK, EU, and Canada to assist you in choosing the best option for your situation.

If you have encountered a different mattress size anywhere in the world, we’d love to hear about it in the comments.

About Discrepancies

It is not uncommon for a particular mattress to not match up exactly to a size listed above. As many aspects of building a mattress are still done by hand, there will always be variations in sizing from one mattress to the next.

Often times, mattresses may measure as much as one or two inches shorter or narrower than the "official" dimensions. This is considered normal.

Choosing the Right Size

When shopping for a bed, determining the most suitable mattress size is paramount. Whether it be a king, queen, single, king single or double bed, BedsOnline are sure to have the perfect mattress, with the right dimensions, for you.

The Single

Single beds have dimensions of 92cm x 188cm, and they are great choices for kids of all ages. A single bed will offer your child enough space to comfortably sleep, as well as enjoy their bedroom’s remaining areas. Single beds are also available in a trundle variant, so you can have a single dimension in a bedroom for two kids.

Single beds are a nice option for students who are living alone and are on a tight budget, due to their value and practicality in saving space, especially if you’re sleeping in a small apartment or dorm room where saving space is a priority.

Singles are also good for guest rooms, providing your overnight visitors with a pleasant night’s sleep. Single beds can be a little bit short for some people though, and this is where you should consider getting a king single mattress with its bigger dimensions.

The King Single

A perfect alternative to a single bed, especially if an ordinary single is just too short for you but don’t have the space for a double bed, or anything larger. The king single bed has the dimensions of 106cm x 203cm, and is perfect for people who are taller than the average height. Like a single bed, it’s perfect for kids. Purchasing a king single mattress can provide a parent with the peace of mind that your growing child won’t need a new bed bought in the near future.

Despite being sizeable, the king single might not have ample space for you, and that’s where you need to browse the larger options which are available.

The Double

Double beds have always been that middle ‘sweet spot’ for a lot of people wanting to buy a bed that is spacious, but not too big to be overbearing in their rooms. With dimensions of 137cm x 188cm, double beds are not as lengthy as a king single, but are considerably wider, allowing more movement during your sleep, or even the addition of a partner – two average sized individuals could comfortably sleep in a double bed. If you’re someone who wants a lot of space in sleeping yet can’t afford a queen or king sized bed, or if you simply don’t have the space for one, the double is just the right bed for you.

A double bed could also do the job for your child’s bedroom. If your kid’s room has enough space for a double sized mattress and if it fits into your budget, your child will love their new bed.

The Queen

Probably the most popular size, the queen size beds provide a solid amount of comfort and luxury. The queen’s dimensions are 153cm x 203cm, easily fitting two people. Queen beds are usually for couples that have an average sized bedroom. They provide plenty of space and come in different varieties where the mattresses are specialized to make sure that you don’t disturb your partner when you get up or move around.

If you sleep alone but want the luxury of having that extra space when in bed, a queen mattress is for you.

Whether you are living alone or with your partner, a queen sized bed offers solid bang for your buck.

The King

With dimensions of 183cm x 203cm, king size beds are extremely wide and provide heaps of space for two. King size mattresses are also suitable for couples who value a lot of space when sleeping.

The king size bed maximizes your comfort when sleeping, thanks to the high-end technology found in most mattresses, which makes sure that your movement doesn’t resonate over to your partner’s size of the bed. It may not be the right fit for everyone, but the king sized bed provides the most luxury in space and comfort.
