Mattress Size Chart for Canada
Every Canadian bed size in inches and centimetres
Twin, Twin XL, Double, Queen, King and California King, with the room size each one needs and how they compare with UK and European beds.
Canada uses six standard mattress sizes: Twin (also called Single) at 38 by 75 inches (97 by 191 cm), Twin XL at 38 by 80 inches (97 by 203 cm), Double (also called Full) at 54 by 75 inches (137 by 191 cm), Queen at 60 by 80 inches (152 by 203 cm), King at 76 by 80 inches (193 by 203 cm), and California King at 72 by 84 inches (183 by 213 cm). Double and Full are two names for the same size, not two different beds. All mattress dimensions below are listed in both inches and centimetres, so this bed size chart works whether you shop in imperial or metric.
Standard mattress sizes in Canada
The mattress size chart below covers almost every bed sold in Canada. Widths vary by up to an inch between manufacturers because finished dimensions are rounded, so a Twin listed at 38 inches may measure closer to 39 inches in one brand and 38 inches in another.
| Size | Also called | Inches (W x L) | Centimetres | Minimum room size | Best for |
|---|---|---|---|---|---|
| Twin | Single | 38 x 75 | 97 x 191 | 7 ft x 10 ft | Children, single sleepers, bunk beds |
| Twin XL | Single XL, dorm twin | 38 x 80 | 97 x 203 | 7 ft x 11 ft | Taller single sleepers, dorm rooms, split king halves |
| Double | Full | 54 x 75 | 137 x 191 | 9 ft x 10 ft | One adult with room to spread out, smaller guest rooms |
| Queen | Standard queen | 60 x 80 | 152 x 203 | 10 ft x 10 ft | Couples, primary bedrooms, the most popular size in Canada |
| King | Eastern King, standard king | 76 x 80 | 193 x 203 | 12 ft x 12 ft | Couples who want maximum width, families who co-sleep |
| California King | Cal King, Western King | 72 x 84 | 183 x 213 | 12 ft x 12 ft | Sleepers over 6 ft tall who need length more than width |
A Double and a Full are the same mattress. "Double" is the common Canadian term and "Full" is the American one, and both describe a bed 54 inches wide by 75 inches long. For a closer look at how the two compare with a Queen, see double and full explained and full vs queen bed sizes.
Less common mattress sizes
These sizes exist but are rarely stocked, so bedding and frames usually need to be ordered specially.
| Size | Also called | Inches (W x L) | Centimetres | Minimum room size | Best for |
|---|---|---|---|---|---|
| Crib | Standard crib mattress | 28 x 52 | 71 x 132 | Fits a standard crib | Infants and toddlers |
| Small Single | Cot size | 30 x 75 | 76 x 191 | 6 ft x 10 ft | Very narrow rooms, camp and cottage beds |
| Full XL | Double XL | 54 x 80 | 137 x 203 | 9 ft x 11 ft | Taller single sleepers who want more width than a Twin XL |
| Olympic Queen | Expanded Queen | 66 x 80 | 168 x 203 | 11 ft x 11 ft | Couples who want more width than a Queen without a King footprint |
| RV Short Queen | Short Queen | 60 x 75 | 152 x 191 | Fits an RV bedroom | Recreational vehicles and campers |
| Split King | Dual King | Two pieces of 38 x 80 | Two pieces of 97 x 203 | 12 ft x 12 ft | Adjustable bases, couples who want independent positions |
| Split California King | Split Cal King | Two pieces of 36 x 84 | Two pieces of 91 x 213 | 12 ft x 12 ft | Adjustable bases where extra length matters |
| Split Queen | Dual Queen | Two pieces of 30 x 80 | Two pieces of 76 x 203 | 10 ft x 10 ft | Adjustable bases in rooms too small for a Split King |
Bunkie boards and trundle mattresses are not separate sizes. A bunkie board is a thin support platform made to match the mattress size above it, and a trundle mattress is usually a Twin built at a reduced thickness so it clears the frame it slides under.
European and UK bed sizes
European and British beds are measured in centimetres and none of them match a Canadian size exactly. If you buy a frame or bedding abroad, Canadian sheets, duvets and frames will not fit correctly.
| UK or EU size | Centimetres | Inches (approx.) | Closest Canadian size | Difference to watch |
|---|---|---|---|---|
| UK Single | 90 x 190 | 35 x 75 | Twin (38 x 75) | About 3 inches narrower than a Canadian Twin |
| UK Double | 135 x 190 | 53 x 75 | Double (54 x 75) | About an inch narrower, bedding runs small |
| UK King | 150 x 200 | 59 x 79 | Queen (60 x 80) | Close to a Queen, so UK king bedding will not fit a Canadian King |
| UK Super King | 180 x 200 | 71 x 79 | California King (72 x 84) | Similar width, about 5 inches shorter |
| EU Single | 90 x 200 | 35 x 79 | Twin XL (38 x 80) | Narrower, close in length |
| EU Double | 140 x 200 | 55 x 79 | Double (54 x 75) | Wider and 4 inches longer than a Canadian Double |
| EU King | 160 x 200 | 63 x 79 | Queen (60 x 80) | 3 inches wider than a Queen |
| EU Super King | 180 x 200 | 71 x 79 | California King (72 x 84) | Similar width, shorter |
How to measure a mattress
Strip the bed first, then measure the bare mattress. Width is the shorter edge running across the bed and length is the longer edge running head to foot. Measure edge to edge at the widest point, since quilted covers and pillow tops can bow outward slightly. Measure depth separately, from the base seam to the top of the quilting, because depth decides which fitted sheets will fit rather than which size the mattress is.
Mattress size versus bed frame size
A frame is always larger than the mattress it holds. Most Canadian frames add roughly 2 to 5 inches to each dimension depending on the rail and headboard design, so a Queen frame typically occupies about 63 by 83 inches of floor space. Platform beds sit at the smaller end of that range and upholstered or storage frames at the larger end. Always check the external dimensions listed for the frame rather than assuming they match the mattress.
Which size to choose
For two adults, a Queen is the practical minimum and gives each person about 30 inches of width. A King adds 16 inches of shared width, which is the single biggest comfort upgrade for couples disturbed by movement. For one adult, a Double is comfortable and a Queen is generous. For children, a Twin works until the teenage years, when a Twin XL or Double buys several more years of use. For a guest room that doubles as an office, a Double is usually the largest size that leaves the room functional.
Room size by mattress size
Allow about 2 feet of walking space on every side of the bed you need to reach. A Queen fits comfortably in a 10 by 10 foot room, and a King generally needs 12 by 12 feet to leave usable space around it. In a room under 10 feet wide a King will physically fit but will leave too little clearance for nightstands and doors. Measure the room before choosing between the two, then read queen vs king vs California king for the full comparison.
Sheet and duvet sizing
Sheets are sold by mattress size, so a Queen fitted sheet fits a Queen mattress. The measurement that matters is pocket depth: check that the depth of the fitted sheet meets or exceeds your mattress depth, including any topper. Duvets run larger than the mattress so they drape over the sides, which is why a King duvet is often recommended for a Queen bed shared by two people. Full and Double sheets are the same product under two names.
Frequently asked questions
What are the standard bed sizes in Canada?
The standard bed sizes in Canada are Twin (38 by 75 inches), Twin XL (38 by 80), Double or Full (54 by 75), Queen (60 by 80), King (76 by 80) and California King (72 by 84). Queen is the most commonly purchased size.
Is a double the same as a full?
Yes. The double bed size and the full bed size are identical: 54 inches wide by 75 inches long. "Double" is the common Canadian name and "Full" is the American name. Sheets and frames labelled either way fit the same mattress.
What size is a queen bed in cm?
A Queen mattress is 152 by 203 cm, or 60 by 80 inches. That gives two people about 76 cm of personal width each, which is why it is the most popular size for couples in Canada.
How wide is a king bed?
A standard King is 76 inches wide, or 193 cm, and 80 inches long. It is 16 inches wider than a Queen and the same length. For frame sizing, room clearance and split king options, see our king size bed dimensions guide.
What is the largest mattress size?
Among standard sizes the King is widest at 76 inches and the California King is longest at 84 inches. Larger sizes such as Alaskan or Wyoming King exist but are custom orders in Canada and are not stocked by most retailers.
What size mattress fits two adults?
A Queen is the practical minimum for two adults at 60 inches wide. A King is the more comfortable choice, giving each person roughly the width of a Twin mattress. A Double at 54 inches works for two adults only occasionally, such as in a guest room.
What size bed fits a 10 by 10 room?
A Queen fits a 10 by 10 foot room with about 2 feet of clearance on three sides. A King will fit physically but leaves under 2 feet on each side, which is usually too tight once nightstands and door swing are considered.
Do bed sizes in Canada match the UK?
No. A UK King is 150 by 200 cm, which is closer to a Canadian Queen than a Canadian King. Bedding bought in the UK or Europe will not fit Canadian mattresses correctly, so buy sheets and duvets sized to the Canadian standard.
What is the difference between a twin and a single?
There is none. Twin and Single describe the same 38 by 75 inch mattress, with "Single" the older Canadian term. For the naming history and how a Twin compares with a Twin XL, see single vs twin bed and twin vs twin XL vs full.
How much bigger is a bed frame than the mattress?
Most frames add about 2 to 5 inches to the width and length of the mattress. A Queen frame usually needs about 63 by 83 inches of floor space. Check the external measurements published for the frame before buying, since designs vary.
