Mattress Sizes Canada: Your Complete Guide to Bed Dimensions (2025)
Updated: March 11, 2025

Below is our mattress size chart, which explains the different bed mattress sizes in cm and inches. Keep scrolling to get a deeper explanation of each size, as well as who each size may be best for.
| Size | Dimensions (LxW) | Required Space |

1. Twin Size
A twin-size mattress in Canada measures 75″ long by 38″ wide (190.5 x 96.5 cm).
This mattress size is perfect for a child’s first bed, a teenager’s bedroom, or anyone who sleeps alone.
It’s also a good fit for bunk beds, loft beds, and other space-saving types of bed frames. If you want a comfortable sleep while saving on square footage, a twin mattress might be your best bet.
However, in other parts of the world (like the UK), single and twin are technically two different mattress sizes. A single mattress is a bit smaller than a twin size at 75″ long by 35″ wide, and it’s typically sold for small children.
Best For: Children and teenagers; anyone who sleeps alone or has limited bedroom space; loft beds and bunk beds.
What’s the difference between a single and a twin mattress?
In Canada, “single” and “twin” are different words to describe the same mattress size.
Is there a bed size smaller than a twin size?
A “small single” size mattress is bigger than a crib mattress but narrower than a twin-size mattress. This size may be harder to find, but it would be ideal for small kids who have graduated from a crib but live in a smaller space.

2. Twin XL Size
A twin XL–size mattress measures 80″ long by 38″ wide (203.5 x 96.5 cm). This makes it five inches longer than a standard twin-size mattress—a good option if you’re on the taller side.
Similar-sized mattresses are also called “single XL” in Europe and “Small Double” in the UK. However, the exact dimensions will be different.
You’ll typically find a twin XL mattress in a teenager’s bedroom or a college dorm. This is technically a standard size but may be harder to find than other mattress sizes. That said, online brands like Juno offer a twin XL mattress size for under $450.
Best For: Taller sleepers who still prefer a twin-size bed, but need more leg room to sleep more comfortably.

3. Double/Full Size
A full or double mattress size is often 75″ long by 53″ wide (190.5 x 137 cm), although some can be 54″ wide. It gives the impression of a larger bed without taking up as much space as a bigger mattress.
Full-size mattresses are a common choice for spare rooms, or for teenagers looking to upgrade their twin-size bed. They provide enough room for one person to spread out but may not have enough space for two.
Need extra legroom for a taller person? You can purchase a Full XL where this size is available. It measures 80″ x 53″ (203 x 134.5 cm), five inches longer than a typical full mattress size.
Best For: One person needing extra space to spread out; couples with smaller rooms or who need less mattress space
What’s the difference between a full and a double mattress?
A full mattress is the same as a double mattress. They’re just two different names for the same mattress. Don’t worry, your full-sized sheets will fit your double mattress without any trouble.
READ MORE: Full mattress vs double mattress size
Is a double mattress big enough for 2 people?
Before queen-size mattresses were introduced in the 1950s, full size/double size mattresses were the standard size for mattresses for couples. This mattress size can sleep two people, but there’s very little room to spare.
Since the introduction of queen and king-size mattresses, it’s more common for both partners to want more room to spread out. You and your partner may be able to share a double mattress, but if you like your space, we recommend upgrading to a queen size if possible.
4. Queen Size
The queen mattress size measures 80″ long by 60″ wide (203.5 x 152 cm). It’s ideal for master bedrooms, guest rooms, and any other space where one or two people need to sleep comfortably. It’s also affordable—for example, a queen-size Douglas costs just $799.
In the UK, queen-size mattresses are also called “king-size” mattresses. Note that these are two distinct mattress sizes in Canada and dimensions will vary.
Queen mattresses are a popular choice because they fit most bedrooms and have enough room for both individual sleepers and couples. However, a queen mattress can get a little cramped when kids or pets climb in.
Need a little extra wiggle room? The Olympic queen-size mattress is wider, measuring 80″ x 66″, and is typically found in RVs and mobile homes.
Best For: Couples; master bedrooms; guest bedrooms with sufficient space
5. King Size
The king mattress size is 80″ long by 76″ wide (203.5 x 193 cm). It’s the widest standard size available, with plenty of room for you to spread out—or for the whole family to get cozy.
This size of mattress is often seen as a luxury. However, it’s possible to get a king-size foam mattress for under $1,000 when you buy from accessibly priced brands like Douglas.
If you and your partner are shopping for a king-size bed but have different mattress needs, consider getting two twin XL mattresses. This is known as a split king mattress and is also an ideal choice for two-sided adjustable beds.
A split king is a good idea if you prefer a softer mattress than your partner, or if one of you needs to sleep at an angle. This mattress works best if you use a split bed base like Douglas’s adjustable bed.
Best For: Couples with kids/pets; couples who want ample space
What’s the difference between a king and a California king mattress?
A king-size mattress is four inches wider and measures 80″ x 76″, while a California king–size is four inches longer and measures 84″ x 72″.
While length and width look different, both mattresses offer the same amount of space, with each measuring 6,048 square inches (or 42 square feet).
READ MORE: Compare California king vs king mattress sizes
6. California King Size
A California king mattress measures 7 feet long by 6 feet wide (84″ x 72″ / 213.5 x 183 cm). This is four inches longer and four inches narrower than a standard king size mattress.
California king mattresses are also known as “grand king” (Europe), “emperor” (UK), and “super king” (Australia).
As the greater length suggests, the California king size bed might be a good fit if you’re a taller person. There’s still enough room to share with a partner, but your feet won’t hang off the edge of the bed.
The California king mattress size can be the most expensive option but should cost the same as a king-size mattress.
Best For: Taller people who want a larger mattress size
Other Oversized King Mattresses
Need extra room in the bed? Consider another oversized king mattress like these:
- The Alaskan king size mattress measures 9′ x 9′ (108″ x 108″ / 274 x 274 cm).
- The Wyoming king size mattress measures 7′ x 7′ (84″ x 84″ / 213 x 213 cm).
- The Texas king size mattress measures 6’8″ by 8’2″ feet (80″ x 88″ / 203 x 249 cm).
These mattress sizes aren’t commonly available and are often custom made.
7. RV Size
An RV mattress is typically 75″ long (190.5 cm), but width can vary depending on the size of the bed frame. There are three common RV mattress sizes:
- RV bunk small measures 2’4″ x 6’3″ (28″ x 75″ / 71 x 190.5 cm). This mattress size will only accommodate a single person.
- RV three-quarter measures 4′ x 6’3″ (48″ x 75″ / 122 x 190.5 cm). You might be able to squeeze two average-sized people onto this mattress.
- RV short queen measures 5′ x 6’3″ (60″ x 75″ / 152.4 x 190.5 cm). This is the same width as a standard queen-size mattress, with enough room for two people of average height.
Mattresses like Douglas and Juno come in all three RV sizes.
Best For: Those who travel in their RVs or campers
Can I put a regular mattress in my RV?
Most RVs don’t have room for standard mattress sizes. You’ll likely need a mattress that’s no more than 75″ long, and narrower than your mattress at home. Measure your RV’s bed frame and compare with our size chart to see what size it can accommodate.

8. Crib Size
Crib mattresses are designed for the tiniest humans, so they’re the smallest mattress size available at just 52″ by 28″ (132 x 71 cm). In Canada, they’re always 6″ high to meet federal regulations for safe sleep.
Crib-size mattresses are made with foam or steel coils. They tend to be much firmer than adult mattresses because a firm surface is generally considered safer for babies.
Best For: Babies; toddler beds that fit a crib mattress

Frequently Asked Questions
What’s the most popular mattress size?
A queen-size mattress (60″ x 80″ / 152 cm x 203.5 cm) is the most popular option for many people, whether they sleep alone or with a partner. It provides plenty of room to spread out while still fitting into a typical bedroom.
A queen-size mattress also has a mid-range price tag, making it affordable for the average person. Brands like Juno, Douglas, Logan & Cove, and Octave all offer a queen size for under $1,000 CAD.
That said, many people also choose a larger king-size mattress (76″ x 80″ / 193 cm x 203.5 cm) or smaller full-size mattress (75″ x 53″ / 190.5 x 134.5 cm). It all depends on how large their room is, how much sleep surface they need, and what they’re willing to spend on a mattress.
What mattress size do I need?
The mattress size you need depends on several factors:
-
-
- Users: If you sleep alone, you can save space and money by purchasing a smaller mattress. On the other hand, you might prefer a larger mattress if you want plenty of room for yourself or share your bed with a partner, kids, or pets. Just make sure the mattress will be long enough to accommodate the tallest person’s height.
- Room: Pick a mattress size that works within your room. Allow space for nightstands and other furniture, and ensure you have space to comfortably move around. You should also consider how to move the mattress into the room, especially if it’s upstairs or around a corner. Purchasing a bed-in-a-box mattress can solve that problem.
- Budget: Your budget is the final word when it comes to choosing a mattress size. Larger mattresses cost more money, and so does quality. Set a budget and shop around to find the right mattress in the size you need. Don’t forget to factor in the cost of your new bedsheets, too.
Looking for a larger mattress with a lower price tag—without sacrificing comfort? Juno offers a king-size mattress for just $599.
Are mattress sizes universal?
No, mattress sizes are not universal. They can vary by country and continent, which can be confusing if you buy a mattress internationally. While some standard sizes are similar across many regions—like a twin/single or a double/full mattress—the exact dimensions can still vary slightly.
If you are buying a mattress internationally for use in Canada, double-check the mattress’s exact dimensions to ensure it will fit with your bed frame before you make a purchase.
Are mattress sizes in Canada the same as the US?
Mattresses from the United States can be half an inch longer, shorter, wider, or narrower than Canadian mattress sizes. However, this isn’t a huge difference, so your Canadian bedsheets should still fit an American mattress and vice versa.
What’s the largest mattress size available?
The Alaskan king size mattress is the largest at 108″ x 108″, or 9 feet by 9 feet. For reference, a California king–size mattress measures 72″ x 84″, or 6 feet by 7 feet. Alaskan king mattresses aren’t commonly ordered, so they’re usually custom made.
What custom mattress sizes are there?
There are several custom mattress sizes that can be found in different kinds of beds, such as:
- RV mattress sizes
- Oversized mattress sizes (e.g., Alaskan king, Texas king, Wyoming king)
- Boat and yacht mattresses (e.g., V-berth, tapered)
- Antique bed mattresses (e.g., three-quarter)
- Uniquely shaped mattresses (e.g., heart, circle)
Custom mattress sizes are harder to find since many mattress retailers predominantly sell standard sizes. However, some brands like Douglas and Juno sell popular RV mattress sizes.
Do custom-size mattresses cost the same as standard-size mattresses?
Common custom sizes like RV mattresses can be priced similarly to standard-size mattresses. However, less common custom sizes are typically more expensive. This is because there’s lower demand and less bulk production, and these sizes can only be produced with specialized machinery.
Can I use 2 single XL mattresses for a king-size bed?
Yes, two twin XL mattresses can be placed side-by-side to make a standard king-sized bed. This is a good idea if you want to use a split king base, which allows you to raise and lower each side of the bed independently.
How do I check my mattress size?
Grab a measuring tape, then measure the length and width of your mattress. Compare it with our size chart to see which size is closest to your mattress. Some mattress brands may be slightly smaller than the standard mattress sizes in the chart, but don’t worry—it’s okay to round up by an inch or so.
Your mattress’s height typically won’t factor into its size (except for crib size). Mattresses can be any height, depending on the brand and construction, but length and width are specific to certain sizes. Still, you may want to measure height so you can buy the right sheets and ensure the mattress will fit your bed frame.

How tall is the average mattress?
Mattresses tend to be 8–14″ tall. However, height varies depending on the type of mattress and the materials used. A foam mattress like Douglas Original is shorter at 10″, while an innerspring or hybrid mattress like Logan & Cove Frontier measures 13.5″ tall.
