Every standard Canadian mattress size, explained in plain terms — dimensions, who each size suits best, and what to check before you buy. All sizes below are available factory-direct through The GTA Mattress with same-day delivery across the GTA.
A Twin mattress measures 38 by 75 inches, the smallest standard adult size sold in Canada. It suits kids’ rooms, bunk beds, and small guest rooms where floor space is limited.
A Twin bed fits comfortably in a room as small as 7 by 10 feet, leaving enough space to walk around the bed and add a dresser or nightstand.
Yes. Twin and Single both refer to the same 38 by 75 inch size — Single is the older term, Twin is the more common name used today.
A Double (also called Full) mattress measures 54 by 75 inches — 16 inches wider than a Twin, but the same length. It’s a solid choice for a single adult who wants more room than a Twin, or a teenager’s growing bedroom.
A Double bed fits well in a room of about 10 by 11 feet, giving enough clearance to walk around the bed and fit a nightstand or dresser.
A Double can work for two people in a pinch, but each person only gets about 27 inches of width — roughly the space of a crib. For couples, a Queen is generally a more comfortable choice.
A Queen mattress measures 60 by 80 inches — 5 feet wide and 6 feet 8 inches long. It’s the most popular mattress size in Canada, comfortably fitting couples and single sleepers who want extra room.
A Queen bed fits comfortably in a room of about 10 by 12 feet, leaving space to walk around the bed and place nightstands on both sides.
A King is 16 inches wider than a Queen (76 vs. 60 inches) but the same 80-inch length. That extra width gives each person in a King about 38 inches of personal space, versus 30 inches in a Queen.
A standard King mattress measures 76 by 80 inches — about 6 feet 4 inches wide and 6 feet 8 inches long, the widest standard size available. It suits couples who want maximum personal space, or families who co-sleep with kids or pets.
A King bed needs a room of at least 12 by 12 feet to comfortably fit the mattress plus walking space and nightstands on both sides.
Yes — a King mattress typically needs a King-specific frame and foundation, often with a center support bar due to its width. We carry matching box springs in all standard sizes.
Side sleepers generally do best on a Gel Memory Foam or Pillow Top mattress. These contour around the shoulder and hip so those joints sink in slightly rather than pressing against a hard surface.
Back sleepers typically do well on a Hybrid or Pocket Coil mattress, which offers steady, even support that holds the lower back without letting the hips sink too far.
A Hard Firm mattress is usually the better choice for stomach sleepers and those managing back pain, since firmer support keeps the hips from sinking and the spine closer to level.
