Mattress Sizes & Dimensions In Canada - Complete Guide

The first step to getting a better night’s sleep is finding the right mattress for your bed. That does not just mean making sure the mattress is comfortable – it also needs to be correctly sized to fit your bed’s frame. While there are no legal guidelines for bed sizes, you can pretty much guarantee that you will find the correctly proportioned mattress you need for your bed, whether it is Twin, Double, Queen, King, or anything fancier. Keep in mind that this information relates specifically to mattress sizes in Canada and the US. Beds may be referred to in different sizing in other parts of the world, so be sure you know your own region’s bed lingo before making a purchase.

In Canada, while you will find all of these mattress sizes, as you could expect, some of them are more common than others. Twin, Twin XL, Double, Queen, King and California King are the preferred mattress options, and it is easy to see why – they are the most practical of the lot, and are more commonly produced and sold by a wide range of mattress brands.

Mattress Sizes & Dimensions

What Affects Mattress Size?

There are a number of factors that may determine the size of a mattress. First of all, the material used to produce the springs in a mattress, and the thickness of this material, may affect the width and length of the spring mattress type. Still, Canadian manufacturers must ensure their sizing is correct to within 1 inch, so there is no need to worry about discovering your mattress is actually much smaller or larger than advertised.

As you can imagine, memory foam mattresses do not vary in size so much, so you can guarantee that they will not even be an inch off their advertised measurements.

Mattress Depth

While all mattresses tend to follow standard width and length guidelines, they vary quite a bit in-depth. Normally, the depth of a mattress depends on the manufacturer and price. Generally, mattresses with less depth are cheaper in price, because you are not getting as much support and cushioning as you would from a mattress with more depth.

Mattress depth fluctuates from roughly 6 to 16 inches. Anything above 10 inches in thickness is usually a safe choice if sleep quality is important to you. Thicker mattresses tend to last longer, too, giving you more value for your money.

Considerations For Mattress Size

If you are buying a mattress to fit a bed frame, there is not too much to think about when it comes to buying a mattress – providing it is the right size, you will be fine. But if you are buying a bed and mattress together, it is worth considering several things:


If you are on the taller side, you might be used to your feet poking out of bed. This, however, does not have to be the norm. For tall children, Twin XL beds and their accompanying mattresses will usually fit them nicely. Tall adults can benefit from the extra length of Double XL beds upwards, or, for particularly tall adults, California King and Texas King beds add even more length.

Room Size

As much as you may love the idea of owning an Alaska King, it may turn out to be an impractical purchase if your bedroom is not big enough to comfortably fit it. A bed and mattress that are too large may overwhelm a room, so if space is limited, a smaller mattress is your best bet.

Sleeping Partner

If you sleep alone, good for you – you get to enjoy the freedom of choosing between virtually all mattresses available on the Canadian market. If you are in a relationship, though, or you have a clingy pet, you will need a mattress with a bit more width. If you and your partner like to snuggle, a Double bed will do you fine. If you prefer your space, consider advancing to a Queen or Olympic Queen mattress.


It goes without saying that you should expect to pay more for a bigger mattress. Make sure you set out a budget in advance so that you can find the best value for the cash you have to spare. If your budget is tight, it is not always the best idea to find the cheapest size mattress possible. For example, you will probably get a much better night’s sleep out of a well-made, super comfortable double mattress than you would from a Queen at a similar price.

Final Thoughts

Aside from mattress sizes in Canada, the type of mattress you opt for is important when it comes to restful sleep. Make sure you are familiar with your options before you begin your search. In any situation, if you are ever unsure about a mattress size, you can always ask your vendor for precise measurements. Generally, though, you should not have a problem with a mattress that is labelled as being a specific size. It is highly unlikely that this advertised size will turn out to be inaccurate.

On a final note, remember that bed linen sizes and mattress sizes do not often add up. We have all bought linen that has ended up being too small for the bed we own. With sheets and throws, the simplest way to avoid this is to buy one size up and tuck in if you need to. With duvets and duvet covers, keep your receipt to hand in case you need to switch for a different size at the store.
