Full Bedsheet Size in Canada: Exact Dimensions, Pocket Depth, and What to Buy

Full Bedsheet Size: The Complete Canadian Guide

Full bedsheet size is one of the most frequently searched bedding dimensions in Canada, partly because the full/double bed remains one of the most common mattress sizes in Canadian homes, particularly in guest rooms, smaller urban apartments, and older housing stock where bedroom dimensions constrain bed size. Yet bedding labels in Canada are inconsistent , some use full, some use double, and pocket depths vary widely without standardisation.

This guide gives you the exact dimensions for full mattresses and full sheets in both inches and centimetres, explains fitted sheet pocket depth in practical terms, covers what to look for when buying full-size sheets in Canada, and clarifies the common points of confusion between full, double, and queen sizing.

Full Mattress Dimensions in Canada

A full mattress (also called a double mattress) in Canada measures:

Dimension	Inches	Centimetres
Width	54 inches	137 cm
Length	75 inches	191 cm

These dimensions are standardised across Canada and the United States. The full/double size is 15 inches wider than a twin (single) and 6 inches narrower than a queen. It is 5 inches shorter than a queen (80 inches), which matters for taller sleepers (above roughly 5 feet 10 inches) who may find the 75-inch length limiting.

Full Fitted Sheet Dimensions

A full fitted sheet is designed with a pocket that wraps around the mattress corners and holds the sheet in place with elastic. The face of a full fitted sheet, before accounting for the pocket depth, is cut at 54 × 75 inches to match the mattress surface.

Pocket depth is the measurement that determines whether a fitted sheet will actually stay on your mattress. Standard pocket depth for full sheets is 10 to 12 inches (25 to 30 cm). Deep pocket full sheets run 14 to 17 inches (35 to 43 cm). Extra deep pocket options reach 18 to 21 inches (45 to 53 cm).

Sheet Type	Pocket Depth	Best For
Standard pocket	10–12 inches (25–30 cm)	Mattresses 8–12 inches thick without a topper
Deep pocket	14–17 inches (35–43 cm)	Mattresses 12–15 inches thick, or mattress + thin topper
Extra deep pocket	18–21 inches (45–53 cm)	Pillow-top, euro-top, or mattress + substantial topper

To find the pocket depth you need, measure your mattress from the top surface to the bottom edge (called the mattress profile). Add any topper thickness. That total is the minimum pocket depth your fitted sheet must provide. A sheet with a pocket depth 2 to 3 inches greater than this measurement will stay secure through the night without constant readjustment.

Full Flat Sheet Dimensions

A full flat sheet is cut larger than the mattress surface to allow for overhang. The standard full flat sheet dimensions are:

Dimension	Inches	Centimetres
Width	81 inches	206 cm
Length	96 inches	244 cm

With a mattress width of 54 inches and a flat sheet width of 81 inches, there is 27 inches of total width to distribute as overhang , approximately 13.5 inches on each long side. This is enough to tuck under the mattress on both sides if you prefer tucked sheets, or to drape over the sides if you do not.

At the length dimension, a 96-inch flat sheet over a 75-inch mattress leaves 21 inches total after accounting for the top-of-bed position. If you fold the sheet back over a blanket or duvet at the head (a "cuff"), this reduces the foot overhang accordingly. Most full flat sheets provide 8 to 12 inches of overhang at the foot, which is sufficient for tucking.

How Full Compares to Other Canadian Mattress Sizes

Mattress Size	Width (inches)	Length (inches)	Common Use
Twin / Single	39	75	Children, bunk beds, solo sleepers in small rooms
Twin XL	39	80	Taller solo sleepers, dormitory beds
Full / Double	54	75	Guest rooms, apartments, solo adults wanting width
Queen	60	80	Couples, master bedrooms
King	76	80	Couples needing maximum width
California King	72	84	Tall sleepers needing extra length

The full/double size occupies an unusual position in the Canadian market. It is wide enough for one adult to sleep comfortably with room to spare, but narrower than most couples would find comfortable for nightly use (the width per person on a full is only 27 inches, compared to 30 inches each on a queen). It is most commonly used in guest rooms, secondary bedrooms, and single-occupant apartments where a queen would not fit or is not warranted.

For families considering a full mattress for a growing child or teenager, it is worth noting that the 75-inch length is the same as a twin. A teen who is expected to grow above 5 feet 10 inches will eventually need a queen or a twin XL for adequate foot clearance. For a comparison of mattress sizes for growing children, our guide to bedsheet sizes in inches covers all Canadian standard dimensions side-by-side.

Why Full Fitted Sheets Keep Popping Off: The Common Causes

The single most frequent complaint about full sheets is that the fitted sheet pops off the corners during the night. This has three primary causes:

Insufficient Pocket Depth

If the pocket depth is less than the combined thickness of your mattress and any topper, the elastic cannot reach past the bottom edge of the mattress to grip. Even if it stretches enough to get on initially, movement during sleep pulls the corners loose.

Worn Elastic

The elastic band at the hem of a fitted sheet typically loses significant tension after 50 to 100 washes, depending on washing conditions. High-temperature washing accelerates elastic degradation. Once the elastic is stretched out, even a correctly sized pocket will not hold.

Wrong Size Sheet

Sheets sold as "full/queen" are designed for neither size precisely. These compromise sheets are cut between the two dimensions and often fit both poorly. Full sheets and queen sheets have meaningfully different pocket circumferences, and a sheet cut for a queen mattress will have too much slack material at the corners of a full mattress, making it prone to bunching and slipping.

The fix: buy a sheet specifically labelled for full size, verify the pocket depth against your mattress profile, and replace sheets once the elastic has noticeably stretched. Fitted sheet straps (corner elastics) can extend the life of a good sheet with worn elastic without buying a full replacement set.

What to Look for When Buying Full-Size Sheets in Canada

Fibre Type

The fibre choice for full sheets is identical to any other sheet size. Long-staple cotton (Pima, Supima, or certified Egyptian Cotton) in the 200 to 400 thread count range offers the best combination of softness and longevity. Tencel and linen are good options for those who sleep warm. Flannel is ideal for winter use in cooler Canadian bedrooms. For a detailed breakdown of fibre options, see our full guide to fine linens and what makes quality bedding.

Pocket Depth

Measure before buying. Manufacturers are not required to standardise pocket depth labelling, and "deep pocket" means different things to different brands. Some deep-pocket sheets are 14 inches; others are 18 inches. The label alone is not sufficient.

Elastic Coverage

Some fitted sheets have elastic only at the four corners; others have elastic running along the full perimeter of the fitted band. Full-perimeter elastic sheets hold significantly better and are worth seeking out, particularly for sleepers who move around frequently.

Certifications

OEKO-TEX Standard 100 is the most broadly useful certification for Canadian sheet buyers, confirming that no harmful substances are present in the finished fabric. It applies regardless of fibre type or country of manufacture.

Full Sheets and Pillow Pairing

Full mattresses are typically paired with standard (50 × 66 cm) or queen-size pillows. A full bed with two standard pillows is the most common configuration. Two queen-size pillows fit across the 54-inch width of a full mattress but leave very little margin on each side, and king-size pillows (50 × 92 cm) extend beyond the mattress width entirely, which is only workable if they are stored sideways at the edge.

For pillow selection guidance, our article on pillowcase sizes covers how to match pillowcase sizing to your specific pillow dimensions, including for standard, queen, and king formats.

Full Mattresses at Mattress Miracle

We carry full/double mattresses in a range of constructions, from coil-and-fibre budget options to latex and hybrid models with substantial profile depths. If you are buying a new full mattress and want to know what pocket depth your new sheets will need before you leave the store, ask our team. We can tell you the exact mattress profile of any model on our floor so you can order the correct sheet size without guessing.

Full mattresses are also frequently purchased for guest rooms where the bed may go months between uses. In those cases, we typically recommend a mattress protector as part of the initial setup, both to extend the life of the mattress and to simplify freshening the bed between guests. For more on how mattress protectors interact with sheet sizing, see our guide on single bedsheet sizes and related bedding dimensions.
