Mattress Sizes in Canada: How to Choose the Perfect Canadian Bed (2025)
Robb Collins
Updated: May 14, 2025
Looking for the perfect mattress size in Canada? This guide breaks down everything you need to know to choose the right size – whether you’re shopping for a compact guest bed or a spacious main bedroom.
At Douglas, we know how much the right mattress size impacts your comfort. That’s why we created this guide – to help you confidently pick the size that fits your space, sleep style, and needs.
We’ll explore standard Canadian mattress sizes, compare dimensions, explain which sizes suit different sleepers, and offer tips on how to measure your space. Let’s find the right size for your best night’s sleep.
Mattress Sizes in Canada Chart: A Quick Comparison
Douglas mattresses are available in six standard Canadian sizes. Use this chart to compare them at a glance:
Note: U.S. mattress sizes are usually within ½ inch of Canadian ones. Most Canadian sheets and bed frames will still fit, but it’s always wise to double-check dimensions before buying.
Standard Canadian Mattress Sizes
Twin / Single Mattress Size
Dimensions: 38″ x 75″
The smallest and most affordable option. Twin is ideal for children, solo sleepers, or compact spaces like bunk beds, dorms, and guest rooms.
Twin XL Mattress Size
Dimensions: 38″ x 80″
Same width as a Twin, but with 5 extra inches of legroom. Twin XL is great for tall sleepers or for use in Split-King adjustable beds (two Twin XLs = one Split King).
Full / Double Mattress Size
Dimensions: 53″ x 75″
A wider option for solo sleepers or teens who like more room. Also works for couples in smaller apartments or guest rooms. Parents often skip the Twin and go straight to a Double for growing kids.
Queen Mattress Size
Dimensions: 60″ x 80″
Canada’s most popular mattress size. Queen offers lots of space for solo sleepers and comfort for couples – without overwhelming your bedroom layout.
King Mattress Size
Dimensions: 76″ x 80″
The largest standard mattress size in Canada. King is perfect for couples who want extra space – or anyone sharing their bed with kids or pets.
California King Mattress Size
Dimensions: 72″ x 84″
Four inches longer than a standard King, California King is ideal for tall sleepers or narrow rooms. Slightly less surface area overall.
Additional Mattress Sizes in Canada
A variety of other mattress sizes are also available, specifically designed to cater to specialized needs. Here are a few examples:
Split King Mattress
Dimensions: two 38″ x 80″ mattresses
Two Twin XL mattresses side by side – perfect for adjustable beds and couples with different sleep preferences. Split King offers the same total surface area as a King.
A Split King mattress configuration, paired with an Adjustable Bed, allows each sleeper to adjust into the perfect position for relief and comfort.
RV Mattresses
Need a mattress for your trailer or camper van? Douglas offers select RV mattress sizes to maximize every inch of space:
RV Bunk (28″ x 75″): Narrow Twin for bunk spaces
RV Three-Quarter (48″ x 75″): Between a Twin and Full
RV Short Queen (60″ x 75″): Same width as Queen, 5″ shorter
All RV mattress models include Douglas comfort, motion isolation, and washable covers. Starting from just $599, with a 365-night trial, 20-year warranty, and a free Comfort Sleep Bundle.
Choosing the Best Mattress Size for You
Mattress prices range from $400 to over $4,000. How do you choose the right one for your budget and your needs?
Tips:
Start with your budget: Set a price range that feels right. Bigger mattresses and premium materials cost more – but you don’t need to overpay for quality.
Don’t base it on price alone: A lower price often means fewer comfort layers or lower durability. If it wears out fast, you’ll be shopping again soon.
Read real reviews: With over 300,000 Douglas mattresses sold, we have thousands of reviews you can filter by features and size.
Consider how many people (or pets) will sleep in the bed: A Queen might feel cramped if you’re sharing with a partner and a dog.
The Douglas Original, for example, starts at just $599, with cooling gel foam, pressure-point relief, and motion isolation. Affordable doesn’t have to mean low quality.

Other Things to Consider
Getting the best bang for your buck isn’t just about price and comfort. It’s also about receiving a top-notch customer experience for years after your purchase.
Shipping and Delivery
Some retailers charge extra for shipping or take weeks to deliver. Douglas offers fast, reliable shipping directly from Canadian warehouses – at no extra cost for most locations. That means you get your mattress quickly and without surprise fees.
Sleep Trial Length
Adjusting to a new mattress takes time. That’s why Douglas gives you a full 365-night sleep trial – so you can test it in every season, risk-free. You’ll have plenty of time to decide if it’s the right fit for your sleep.
Returns and Refunds
Douglas makes returns easy. If the mattress isn’t right for you, we’ll pick it up and issue a full refund—no hidden conditions. Just keep your original packaging until you’re sure it’s a keeper, as some returns may require it.
Warranty Coverage
A quality mattress should last for years. Douglas Original is backed by a 20-year warranty – well beyond the industry standard. Be sure to read the warranty terms so you know exactly what’s covered and how it works.
Brand Reputation
Before you buy, take time to research the company behind the product. Douglas is one of Canada’s best-reviewed mattress brands, with over 300,000 sold, multiple awards, and thousands of verified 5-star reviews from real customers.
