- Variety of Sizes: Canada offers a range of mattress sizes to accommodate different needs, from crib mattresses for infants to larger options for adults. These sizes include standard sizes like twin, queen, and king, as well as unique sizes like half queen and queen RV to fit specific requirements.
- Consider Room Size: When choosing a mattress size, it’s important to consider the dimensions of your room. A mattress should provide ample space for comfortable sleep without making the room feel crowded. Larger rooms can accommodate larger mattress sizes, while smaller rooms may require more compact options.
- Sleeping Preferences: The choice of mattress size should also take into account the number of people who will be sleeping on it and their sleeping preferences. Couples often opt for queen or king sizes for more space, while individuals may find twin or twin XL sizes suitable. Additionally, some mattress sizes, like the twin XL, are designed to accommodate taller individuals.
Regardless of where you are in the world, it’s important to consider your bed’s ideal size. Some Canadian shoppers may feel overwhelmed by the range of choices available, which is why we rounded up the most common mattress sizes and their dimensions. We offer a quick description of each size, making it easier to pick the best mattress for you.

Crib mattresses are designed for cribs only, being too thin and small to provide comfort for a growing child or adult. The crib mattress should be under 15 cm thick and shouldn’t leave more than 3 cm of space by the side of the crib.when it comes to crib mattresses.
A half queen mattress is usually used to form a split queen bed, which allows two people to choose a different firmness on each side of the queen mattress. A split queen mattress also allows sleepers to set up the mattress in two different positions on an adjustable bed; a handy feature if one partner likes to sleep elevated while the other prefers a flat surface.
Sometimes referred to as a cot, a small single mattress is typically paired with a low-profile toddler bed frame. It’s a good in-between size for young children that have outgrown a crib but aren’t quite ready for a traditional bed.
Twin size mattresses are the most compact size carried by the average mattress company. The bed size can easily fit in a small or oddly shaped room. Some people don’t even buy a twin mattress to sleep on, using it with a daybed instead of a standard sofa.
Parents often buy a twin mattress for their children, but if they want to take advantage of one of the most durable mattresses, they might want to consider a twin XL bed instead. The bed is slightly longer and can better accommodate their teenagers’ growth spurt.
Twin/Single Extra Long
A twin XL size mattress, sometimes called a single XL, is usually 5 or 6 inches longer than a traditional twin bed. The added length keeps a taller sleeper’s feet from dangling over the edge, which can significantly impact comfort.
Because a twin XL mattress can accommodate more sleepers than a traditional twin without taking up too much space, they’re a common feature in college dorm rooms. Many people also choose a twin XL bed for a smaller guest room.
Full size mattresses are a great way to upgrade a small bedroom. They’re as long as a standard twin but offer 16 more inches of width, giving a person room to roll about and spread their limbs. While a full mattress is great for a single sleeper, we don’t recommend full beds for couples. They’re half a foot narrower than a queen, enough space to leave two people feeling cramped.
As the name suggests, a queen RV size mattress is specifically designed to fit inside a recreational vehicle. It’s shorter and often thinner than a typical queen mattress to reduce drag on the RV.
A queen size mattress is perhaps the most popular mattress size. Many couples choose to sleep on a queen bed because it offers personal space for two people without taking up an excessive amount of room space. Other couples (and some single sleepers) choose a queen mattress for its affordability.
The traditional king size mattress, sometimes called the Eastern king to differentiate it from the California king mattress, is the largest size carried by many mattress companies. It’s a good fit in larger master bedrooms, giving sleepers plenty of personal space. Parents may even choose to occasionally co-sleep with their child on a king size bed.
Some companies also offer a split king mattress, which has the same dimensions as a king mattress. Essentially, a split king mattress is two twin XL size mattresses pushed together, promoting greater freedom of movement on an adjustable frame.
A California king size mattress, also known as Western king, is a longer and narrower version of the standard king mattress. Taller people who have to fold their bodies to fit on even a traditional king can comfortably stretch out on a California king size mattress. The size is also a good fit in narrower master bedrooms.
Super king isn’t a common mattress size, but it’s still possible to find mattress companies that offer one. Because it’s not a standard size, the exact dimensions often vary. As the name suggests, though, it’s typically a larger version of the standard king mattress.
If you can’t find a super king size bed, you may be able to commission one from a custom mattress maker. You may also see the size referred to as the “grand king” or “athletic king.” In America, it’s often called the “Texas king.”

At Amerisleep, we don’t believe in one mattress that’s perfect for everyone. That’s why, instead of concentrating our efforts on one mattress, we diversified and made mattresses in five firmnesses.
Our AS1 model is our firmest and thinnest mattress, standing 10 inches tall. It is available only as a memory foam mattress. The firm surface promotes a secure feel, buoying the body. We recommend our AS1 mattress for stomach sleepers seeking a way to keep their spines from bowing too far into the mattress.
Next is our AS2 model with a medium-firm feel. It’s 12 inches tall and comes in memory foam and hybrid versions. The slightly softer feel of the mattress increases its contouring ability, enabling it to mold closer to the body for pressure relief. We recommend our AS2 mattress for back sleepers, particularly ones looking for a mattress to ease
Our most popular mattress is the AS3 model, with a medium feel suitable for side, back, and combination sleepers. Because the 12-inch tall mattress supports a wide range of sleeping styles, the AS3 mattress is popular with couples who prefer different positions.
After the AS3 is the medium-soft AS4, 12 inches tall and exclusively available as a memory foam mattress. Its thick cushion offers pressure relief for side sleepers and people under 130 pounds.
Last is our AS5 model, the softest and thickest mattress we offer. To keep sleepers from sinking too far into this 14-inch mattress, we included a layer of responsive Active Flex material underneath the mattress’s comfort layer. Active Flex has a latex-like buoyancy, offering pushback without reducing the mattress’s soft feel.
We recommend the AS5 for side sleepers and petite people who want a mattress that hugs their body while offering responsive support and pressure relief.
Every memory foam and hybrid mattress contains a top layer of Bio-Pur® foam, an environmentally friendly alternative to traditional memory foam. Bio-Pur® foam is also more breathable and responsive than the average memory foam.
All of our mattresses also include a 100-night sleep trial and a 20-year warranty. If you are not happy with the comfort and support of your new mattress, we will provide a full refund.
Choosing the Best Mattress Size
So how does one choose the best mattress size? It mostly comes down to four factors:
- How many people will sleep on the mattress
- The height of the sleeper(s)
- Your room size
- Your budget
A good mattress size gives you space to move and stretch out, ensuring your arms or legs aren’t hanging over the mattress’s sides. When it comes to mattresses for couples, we can’t suggest anything smaller than a queen size mattress. Single sleepers have more freedom when it comes to choosing a mattress size for their needs.

Frequently Asked Questions
Are mattress sizes universal?
No, mattress sizes differ depending on where in the world you are. For example, a king size mattress in the UK measures 59 inches by 79 inches, while a king size bed in the USA is 76 inches by 80 inches. Plus, many countries choose to measure their mattresses in centimeters rather than inches.
Do queen mattresses come in different sizes?
Yes, there are numerous variations of the traditional queen bed size. If you’re looking for an RV size mattress, the Queen RV is about 5 inches shorter than a regular queen bed.
An Olympic queen mattress is 6 inches wider than a standard queen, while a California king is 4 inches longer than a traditional queen. There are also split queen mattresses with the same dimensions as a regular queen bed, but the bed is divided into halves to promote greater customization on an adjustable bed.
Is a double the same as a queen bed?
No, a double bed or full size mattress is shorter and narrower than a queen mattress. A full size mattress measures 54 inches wide and 75 inches long. Queen size bed dimensions are 60 inches by 80 inches. Similarly, a double or full XL mattress isn’t the same thing as a queen mattress, measuring 54 inches wide and 80 inches long.
While this difference may seem slight, it’s enough for us not to recommend full beds for couples. That 6-inch difference in width can still significantly impact comfort, leaving each partner with a sleeping area roughly the same width as a crib mattress.
What is an Alaskan king size bed?
An Alaskan king is an oversized mattress measuring 108 inches by 108 inches, or 9 feet on all sides. Most mattress companies don’t carry oversized mattresses like the Alaskan king, so if you’re interested, you’ll likely have to custom order one from a manufacturer. Because of its large size, we don’t recommend this bed for any room smaller than 16 feet by 16 feet.
Can you use a piece of plywood instead of a box spring?
Yes, a piece of plywood cut to fit a mattress can make a suitable bed base. The plywood should be at least 0.75 inches thick to provide consistent support for your mattress. You can also look for a bunkie board, which is around 2 to 3 inches thick and often covered in upholstery to keep the mattress from sliding.
You can also use a plywood board with a box spring if you want. This allows you to use the box spring for added bed height while still supporting a memory foam or hybrid mattress needs. Remember, we don’t recommend placing a memory foam mattress directly on a box spring because box springs are designed to only support innerspring mattresses.
Choosing the right size mattress is just as important as making sure the bed provides a comfortable feel. A too-large bed can make a room feel crowded, while a too-small mattress might leave a sleeper feeling cramped and uncomfortable. Taking a few moments to plan where your bed foundation and other furniture will go is often the best way to promote a relaxing atmosphere.
