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:

SizeDimensions (Width x Length)Surface Area (Square Inches)
Twin / Single38″ x 75″2,850
Twin XL38″ x 80″3,040
Full / Double53″ x 75″3,975
Queen60″ x 80″4,800
King76″ x 80″6,080
California King72″ x 84″6,048

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 mattress

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

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

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

Split King Adjustable 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.

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.
