There are 6 mattress sizes that most mattresses are available in. Twin, Twin XL, Full/Double, Queen, King, and California King are the standard mattress sizes and the only sizes you’ll be looking at when shopping most mattress brands. Mattresses are categorized by dimensions, but height does not factor in at all. Let’s take a look at all the different mattress sizes in Canada and how to choose the right one for you.

What are the different mattress sizes in Canada?

There are a total of 11 mattress sizes to consider, ranging from crib-sized to family-sized, but some of these are specialty mattress sizes that are much harder to find. We’ll look at these mattresses in two groups: standard and non-standard.

Standard mattress sizes

Standard mattresses are Twin, Twin XL, Full/Double, Queen, King, and California King. The Twin bed measures 38 x 75 inches. The Twin XL bed measures 38 x 80 inches. The Full/Double bed measures 53 x 75 inches. The Queen bed measures 60 x 80 inches. The King bed measures 76 x 80 inches. Finally, the California King bed measures 72 x 84 inches.


  • 38” x 75” | 96.5 x 190.5 cm

At 38 x 75 inches, the Twin mattress is the best choice for a growing child’s bedroom since it has the length to accommodate years of growth into teenage-hood. It can also fit adults under 6’ tall in a pinch, but they work best for bunk beds or younger single sleepers.

Twin XL

  • 38” x 80” | 96.5 x 203.2 cm

The Twin XL is very similar to the Twin in terms of purpose, but has an extra 5” of length that makes it better for tall sleepers above 6’. This bed is still great for the same applications as the Twin, but it can fit an adult more comfortable and is a good choice for small guest rooms or dorm rooms.


  • 53” x 75” | 134.6 x 190.5 cm

The Double/Full mattress is the smaller mid-size mattress size available at most retailers and is commonly chosen for guest rooms, young adults, or couples who either love to cuddle while they sleep or who are smaller in stature. At 53 x 75 inches, this mattress is a bit harder for tall adults to sleep on unless they curl up, but it is a popular choice for single sleepers wanting an upgrade from the Twin beds.


  • 60” x 80” | 152.4 x 203.2 cm

The Queen mattress is the most popular mattress size. It is the perfect size for couples to share and is comfortable to sleep on even with pets thanks to the more generous 60” x 80” measurements. You will need a larger room to comfortably fit the Queen mattress, so it isn’t a great choice for people in studio apartments as a general rule.


  • 76” x 80” | 193 x 203.2 cm

The King mattress is ideal for couples who like to spread out while they sleep or who sleep with pets or children in the bed with them. Since this mattress measures 76” x 80” long, you’ll want a room at least 12 x 12 feet to comfortably fit this extra-wide bed.

California King

  • 72” x 84” | 183 x 213 cm

The California King mattress is the longer, skinnier cousin of the King at 72 x 84 inches. This mattress is designed for couples who are tall or who want their pets at the end of their bed. This bed is only slightly thinner than the ordinary King, so children could still share the bed if needed.

Non-standard mattress sizes

Non-standard mattresses include the Olympic Queen, Wyoming King, Texas King, and Alaskan King. The Olympic Queen bed is 66 x 80 inches. The Wyoming King bed is 84 x 84 inches. The Texas King bed is 80 x 98 inches. Finally, the Alaskan King bed is 108 x 108 inches. Though interesting to know, when shopping for a mattress you’ll most likely only have the standard mattresses sizes to choose from.

Top recommended mattress for Canadians

Douglas Mattress

Our top recommended mattress is the Douglas. The Douglas is a medium-firm, all-foam mattress that is both very high-quality and quite affordable. This value-packed bed is a great fit for any type of sleeper and is comfortable for everyone. It comes with a 15-year warranty and a 120-night sleep trial so you can feel confident in your purchase and try it out risk-free. The Douglas mattress is a Canadian-made bed recommended for everyone from couples to restless sleepers to hot sleepers and more.

The bed is quite simple in design with only three layers to its structure. First is the comfort layer, which is made of 2-inch layer of ecoLight cooling gel foam that dissipates heat from your body and keeps the mattress cool to sleep on. The next layer is made of premium Elastex foam and is also 2 inches thick. This layer mimics the benefits of latex, being naturally supportive, resilient, and providing more bounce and responsiveness than memory or poly foams.

The final layer of the bed is the support layer and is 6 inches tall. It is a specialty motion isolation foam that stops motion transfer in its tracks so restless sleepers can stay asleep and couples aren’t disturbed by each other’s movements. The Douglas mattress is quite reliable for edge support as well and is compatible with adjustable bed frames so you aren’t at all limited by your choice of foundations. The bed also comes with a protective cover that uses a proprietary CoolSense eucalyptus fabric for cooling and moisture wicking – it’s even washable for your convenience.

Overall, there is nothing that the Douglas bed doesn’t offer, from cooling to pressure relief to the perfectly balanced support you need for a wonderful night’s sleep.

Tips for choosing a mattress size in Canada

Choosing a mattress size is actually quite simple: there are only a few things to consider before settling on a mattress size.

Single sleeper vs. multiple sleepers

The most important factor to think about when choosing a mattress size is who will be sleeping on that mattress. Single sleepers are comfortable on Twins, but couples would need a Double at minimum, though a Queen is best for comfort. If you plan on having your children sleep with you, the regular King is better than the California King or the Queen King since you have greater width. If sleeping with pets, the California King size is probably more fitting since they can sleep comfortably at the end of the bed thanks to the extra length.


Naturally, the larger the bed, the more expensive it will be. Though we’d probably all like to sleep on a King mattress, the price is not feasible for many and a Queen is often the most reasonable choice for couples. For single sleepers, the Twin options are the best value since the Double is close to the price of a Queen in most cases.

Your height

Particularly for single sleepers, your height can be the most determining factor when choosing between the Twin and Twin XL. Since the only difference between the two is 5 inches of length, the Twin is the better choice if you’re less than 6 ft tall. For couples deciding between the King and California King, you’ll only be considering a length difference of 4 inches, so it isn’t always a better value unless you have pets that will be joining you.

Room size

Though this is an often overlooked consideration, your room size is one of the most important things to consider when choosing the size of your bed. You want to have at least two feet of space on either side of your mattress so you can maneuver easily, so sometimes the Queen is the best choice for your room even if you really want that luxurious King mattress.

Final thoughts

Well, there you have it – all the mattress sizes in Canada to consider and how to choose the best size for you. Though the specialty mattress sizes are cool, and we may all dream about those party-sized mattresses for movie marathons on rainy days, the standard mattress sizes are much more affordable, easier to find, and more convenient for accessories like bed frames and sheets. We hope you now have a great understanding of what mattress size suits you best.
