Mattress Sizes Canada: Your Guide to Bed Dimensions (2024)

1. Twin Size

A twin-size mattress 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.

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.

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.

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.

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.

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.

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.

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.

This is a popular mattress choice because it fits most bedrooms and has enough room for both individual sleepers and couples. However, it gets a little cramped when kids or pets climb in.

(Shopping for a queen-size mattress? Consider Douglas, this year’s top pick at just $799 for a queen, or check out our list of the best queen-size mattresses in Canada.)

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.

However, this isn’t a standard size so it may be difficult to find. You may also struggle to find a matching bed frame and sheets. An alternative would be upgrading to a king size if you have the space and budget.

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 one of Canada’s best king-size mattresses from accessibly priced quality 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. (Get our ranked list of the best adjustable beds in Canada.)

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.

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).

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.

As the greater length suggests, the California king 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. The square footage is the same—it’s just distributed a little differently.

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 come in all three RV sizes.

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.
