Mattress Sizes in Canada 2026: Twin, Double, Queen and King Explained

Buying a mattress in Canada starts with one seemingly simple question: what size do you need? The answer depends on who will sleep on it, how large your bedroom is, and whether the bed frame you already own matches the dimensions. Canada follows North American sizing standards — the same ones used in the United States — which differ significantly from European sizes. Whether you are outfitting a child’s room with a Twin, replacing a couple’s Double or stepping up to a Queen or King, understanding the exact dimensions and the logic behind each size will save you from costly mistakes.

This guide covers every standard Canadian mattress size in 2026: Twin, Twin XL, Double, Queen, King and California King — with measurements in both inches and centimetres — along with advice on which room dimensions work best with each.

Canadian Mattress Sizes at a Glance

Before diving into the details of each size, here is the complete reference chart:

Canada uses the same standard dimensions as the United States, so a Queen, King or any other size purchased from a Canadian retailer will match US-made bed frames and bedding without any conversion needed.

One source of confusion is the naming system itself. Several sizes have at least one alternate name, and some have several. Customers regularly ask for a “Full” and are surprised to learn it is the same as a “Double,” or they request a “King” and need clarification on whether that means a standard King or a California King. The chart above lists the most common alternative names to help you navigate retailer listings and product pages with confidence.

Twin (38″ × 75″ / 96 × 191 cm)

The Twin mattress measures 38 inches wide by 75 inches long — 96.5 by 190.5 centimetres. In Canada, this size is frequently called a Single, while in the United States the name Twin is more common. It is the smallest standard mattress available and the natural choice for children’s bedrooms, bunk beds and daybeds.

A Twin suits one sleeper comfortably, provided that sleeper is not exceptionally tall (the 75-inch length can feel restrictive for adults over five feet ten). A Twin mattress fits comfortably in a room as small as 8 feet by 10 feet with walking space on both sides, and for a comfortable setup with a small desk or dresser alongside the bed, you should aim for at least 9 feet by 11 feet.

Twin XL (38″ × 80″ / 96 × 203 cm)

The Twin XL keeps exactly the same width as the Twin but adds five inches of length, bringing it to 38 inches wide by 80 inches long (96 × 203 cm). Twin XL mattresses work well for people over six feet tall who need the extra length without requiring a wider mattress. This makes the Twin XL a popular choice for teenage bedrooms, university dormitories and guest rooms where floor space is limited but the sleeper is tall.

A room measuring at least 2.4 by 3 metres works well for a Twin XL bed; smaller rooms can still accommodate this mattress if you are willing to sacrifice some walking space.

There is also a practical long-term advantage to the Twin XL: two Twin XL mattresses placed side by side form a split King bed, allowing each partner their own mattress with their own firmness level while the bed looks and functions as a standard King. If you are buying a Twin XL now, it can eventually become half of a split King setup later.

Double / Full (54″ × 75″ / 137 × 191 cm)

The jump from Twin to Double adds 16 inches of width — approximately 42 percent more sleeping surface — while keeping the same 75-inch length. This makes the Double (also called Full) an appealing step up for a single adult who moves around during sleep and wants extra room to stretch without committing to a Queen.

For couples, the Double is technically serviceable but tight. Each person ends up with roughly 27 inches of personal width, which is noticeably narrower than a standard cot. Couples who share a Double for occasional nights will manage, but for a primary bed shared nightly, a Queen is a significantly more comfortable choice.

The Double is well suited to:

• Single adults who want more room than a Twin provides without upgrading to a larger frame;
• Guest bedrooms with moderate floor space where a Queen would be oversized;
• Studio apartments where the bedroom and living areas share space.

Queen (60″ × 80″ / 153 × 203 cm)

The Queen is Canada’s most popular size for couples. At 60 inches wide by 80 inches long (153 × 203 cm), it offers each of two sleepers about 30 inches of personal width — a meaningful improvement over the Double. The Queen also matches the length of the Twin XL, which means tall sleepers sleeping alone can consider a Queen without the risk of their feet hanging off the end.

The Queen is also the most widely stocked size across Canadian retailers, which translates into the broadest selection of frames, bed bases, mattress toppers and fitted sheets. If you are uncertain which size to buy and your room can accommodate it, the Queen is almost always the safest choice.

From a room-planning perspective, it is advisable to leave 60 to 90 centimetres of walking clearance on each open side of the bed. For a Queen, this means a bedroom of roughly 10 feet by 12 feet (about 3 × 3.7 metres) gives a comfortable layout with clearance on both sides and space for a bedside table.

King / Eastern King (76″ × 80″ / 193 × 203 cm)

The King mattress — also called the Eastern King — measures 76 inches wide by 80 inches long (193 × 203 cm). It is the widest standard mattress available in Canada and gives couples a truly generous amount of personal space: roughly 38 inches each, which is slightly more than an entire Twin mattress per person.

The King is ideal for:

• Couples who need space — light sleepers, people who share their bed with a pet or a child, or anyone who simply values room to spread out;
• Master bedrooms with sufficient floor space — plan for a room of at least 12 feet by 12 feet (3.7 × 3.7 metres) to maintain comfortable clearance;
• Sleepers who run warm — a larger surface area means less body heat concentrated in the centre of the mattress.

The main drawbacks of the King are weight, cost and the logistics of getting it through doors and up stairs. King mattresses are heavier and more expensive than Queens, and the 76-inch width can make manoeuvring through standard hallways challenging.

California King (72″ × 84″ / 183 × 213 cm)

The California King is often confused with the standard King, but the two sizes are quite different in shape. A California King is narrower but longer than an Eastern King: 72 inches wide by 84 inches long (183 × 213 cm), versus the Eastern King’s 76 inches wide by 80 inches long.

In practice, the California King trades four inches of width for four inches of extra length. This makes it the preferred option for very tall sleepers — anyone over six feet four inches will appreciate the additional legroom. It is less suited to couples who prioritise side-by-side width, since it is actually narrower than a standard King.

One important note for Canadian shoppers: California King bedding — fitted sheets, duvet covers, mattress protectors — is less common in Canadian retail than standard King bedding. Before committing to a California King, verify that your preferred bedding brand carries the size.

How Canadian Sizes Differ from European Sizes

If you have previously bought a mattress in Europe — whether in France, Germany, the UK or elsewhere — Canadian sizing will look quite different. EU Single mattresses are 80 or 90 cm wide and 200 cm long, which is narrower than a Canadian Twin and three inches longer. An EU Double measures 140 × 200 cm, making it slightly wider than a Canadian Double and also three inches longer. The EU Queen or Standard size is 160 × 200 cm — wider than a Canadian Queen by roughly 7 cm, but slightly shorter. The EU King runs 180 × 200 cm, which is significantly narrower than a Canadian King.

The practical consequence: European bedding, bed frames and mattress toppers will not fit Canadian mattresses without significant size discrepancies. If you are relocating to Canada from Europe (or the reverse), plan to replace your full bedding setup rather than assuming compatibility.

Choosing the Right Size: A Practical Framework

Use the following decision logic to narrow down your choice:

Who will sleep on it?

• One child or a young teenager → Twin or Twin XL (if tall)
• One adult, moderate space → Double
• One adult, wants comfort or will share occasionally → Queen
• Two adults as a primary sleeping surface → Queen at minimum, King for maximum comfort

How large is your room?

• Under 9’ × 10’ → Twin or Twin XL only
• 10’ × 10’ → Double is comfortable, Queen is possible
• 10’ × 12’ → Queen fits well with good clearance
• 12’ × 12’ and above → King or California King become practical

Are you particularly tall?

• Under 5'10" (178 cm) → any standard length (75″) is fine
• 5'10″ to 6'4″ → choose a mattress with an 80″ length (Twin XL, Queen, King)
• Over 6'4″ → California King (84″ length) is the most comfortable option

Do you share the bed with a partner?

• If yes, go at least to a Queen. The Queen gives 30 inches per person; the King gives 38 inches each — a difference that becomes very tangible over years of nightly sleep.
