Canadian mattress sizes are pretty much identical to US mattress sizes: Twin/Single (38" x 75"), Twin XL (38" x 80"), Full/Double (54" x 75"), Queen (60" x 80"), King (76" x 80"), and California King (72" x 84"). However, California Kings are less common in Canadian showrooms and may require a custom order.
Key Takeaways:
Twin mattresses, also known as single mattresses, measure 38 inches wide and 75 inches long. They're commonly used for children's beds, bunk beds, and smaller bedrooms. Given the narrow 38-inch width of a twin bed, it's much easier to fit in small spaces. Twin beds are ideal for guest rooms, children, teenagers, and single adult sleepers. They're highly budget-friendly for those who sleep alone. But taller people may find twin-size mattresses restrictive because of their 75-inch length.
Twin XL mattresses, sometimes known as single extra-long or single XL, measure 38 inches wide and 80 inches long. They have the same width as a twin but are 5 inches longer, hence the "XL" in their name. The 38-inch width makes the twin XL bed another good candidate for smaller rooms. Twin XL beds are often used in guest rooms, dorm rooms, and for growing teenagers and tall solo sleepers. They offer more legroom for tall sleepers (above 6 feet) to stretch out.
A full-size mattress, also known as a double mattress, measures 54 inches wide and 75 inches long. It provides 16 inches of extra space compared to a twin mattress. The 54-inch width makes a full mattress adequately spacious for single sleepers. Full-size beds used to accommodate two sleepers, but now are mainly used by single sleepers who want more space at an affordable price.
Pro-Tip: Full beds can be restrictive for tall sleepers above 6 feet due to their 75-inch length. You'll want to consider a full XL in this case, which is 54 inches wide and 80 inches long.
Queen mattresses, the most popular sizes in Canada (same as the US), measure 60 inches wide and 80 inches long. Queen-size beds improve on the dimensions offered by full beds, providing 6 inches of extra width and 5 inches of extra length, making them the perfect budget-friendly option for couples. Queen beds are also quite spacious for single sleepers, including co-sleeping single parents and pet owners.
Pro-Tip: Go for a split queen mattress (two separate mattresses, each 30 x 80 inches, forming a queen-sized bed) if you and your partner have different sleep preferences.
King mattresses measure 76 inches wide and 80 inches long, and are the largest standard mattress size available in Canada. They're 16 inches wider than a queen mattress, ensuring plenty of space for couples who prefer their personal sleeping space. To add to that, families with children/pets will also find a king-size bed ideal for their co-sleeping needs.
Pro-Tip: Go for a split king mattress (two twin XL mattresses together forming a king-sized bed) if you and your partner have different sleep preferences.
California king mattresses measure 72 inches wide and 84 inches long. While not as common as other mattress sizes in Canada, they are still among the standard mattress sizes sought annually. Longer and narrower than a standard king mattress, a Cal king is better suited for couples/families with tall sleepers who need the extra length. Since they're uncommon in the industry, however, finding a California king-size bed frame or bedding accessories can be challenging.
Pro-Tip: Go for a split California king mattress (two separate mattresses, each 36 x 84 inches, forming a Cal king-sized bed) if you and your partner have different sleep preferences.
Ask yourself these five things:
Measure your room before anything else. A queen mattress needs at least a 10 x 10 foot room, and a king needs at least 12 x 12 feet to leave enough space to move around comfortably. Leave at least 24 inches on the sides of the bed and 36 inches in front of any dressers/closets. If the numbers don't add up, size down. A bed that crowds the room will bother you every day.
A queen bed provides 30 inches of width per person, which is good for average-sized couples. A king bumps that to 38 inches each, closer to what you'd get on a twin bed to yourself. If you and your partner share the bed with a large pet or a child who climbs in at night, the extra width of a king is worth serious consideration if the room can handle it.
If either sleeper is over 6 feet tall, a standard twin or full at 75 inches long may be too short. A twin XL, queen, and king all measure 80 inches long, while the California king stretches to 84 inches, making it the best option for very tall sleepers. Consider weight too, since heavier sleepers need a mattress thick enough (at least 10 inches) and firm enough to support them properly, regardless of size.
Think about the next 5 to 10 years, not just right now. If you're in a starter apartment, say a studio, then a full bed might be the practical choice today, but if you're planning to move into a larger home, buy for where you're headed. If you're buying for a child, consider whether a twin XL makes more sense than a standard twin, so that you're not replacing it in a few years when they hit a growth spurt.
Mattress prices scale with size. In Canada, a queen costs around $200 to $500 more than a twin in the same model, and a king adds another $300 to $600 on top of that. Don't forget to factor in a bed frame and bedding, too, as these add up fast and are often sized differently, so you can't always reuse what you have. Set a total budget for the whole setup.
