Size of Single Bedsheet: Complete Dimensions Guide for Canadian Shoppers

Single Bedsheet Dimensions: The Exact Numbers

The size of a single bedsheet depends on whether you are looking at a fitted sheet, a flat sheet, or a complete set. Here are the standard measurements used by Canadian bedding manufacturers:

• Fitted single sheet: 39 inches wide x 75 inches long (with a pocket depth of 10 to 15 inches)
• Flat single sheet: 66 inches wide x 96 inches long
• Standard pillowcase (included in most single sets): 20 inches wide x 26 to 30 inches long

The flat sheet is intentionally larger than the mattress so it can be tucked under the mattress on all sides. The 66-inch width gives roughly 13.5 inches of tuck-in room on each side of a 39-inch mattress, which is more than enough for a hospital corner or a simple fold.

Single vs. Twin: Are They the Same?

In Canada and the United Kingdom, a single bed is the same as a twin bed in the United States. The mattress dimensions are identical: 39 inches wide by 75 inches long (99 cm by 190 cm). The terminology differs by country, but the sheets are interchangeable.

If you are shopping online and see a product listed as "twin sheets," those will fit your single bed in Canada without any issue. The same is true in reverse: Canadian single sheets will fit an American twin mattress.

Where confusion arises is with twin XL, which is a distinct size. Twin XL mattresses are 39 inches wide but 80 inches long, five inches longer than a standard single. Single sheets will not fit a twin XL mattress properly and the fitted sheet will likely pop off the corners. Always confirm which size your mattress is before ordering sheets.

All Standard Bedsheet Sizes at a Glance

Bed Size	Mattress (inches)	Fitted Sheet (inches)	Flat Sheet (inches)
Crib	28 x 52	28 x 52	36 x 58
Single / Twin	39 x 75	39 x 75	66 x 96
Twin XL	39 x 80	39 x 80	66 x 102
Double / Full	54 x 75	54 x 75	81 x 96
Queen	60 x 80	60 x 80	90 x 102
King	76 x 80	76 x 80	108 x 102
California King	72 x 84	72 x 84	108 x 106

These are the dimensions manufacturers use as their baseline. Fitted sheet pocket depth is a separate specification that is not captured in the length and width measurements above. More on that in the section below.

Pocket Depth: The Measurement Most Shoppers Overlook

The pocket depth of a fitted sheet is the height of the elastic-trimmed pocket that wraps around the mattress corners. If your mattress is taller than the sheet's pocket depth, the sheet will not stay on. This is one of the most common complaints about sheets that otherwise appear to be the correct size.

Mattress Height	Pocket Depth Needed	Sheet Type
Up to 10 inches	10 inches	Standard fitted sheet
10 to 14 inches	12 to 14 inches	Standard to deep pocket
14 to 18 inches	15 inches	Deep pocket fitted sheet
18 inches and above	18 to 21 inches	Extra deep pocket fitted sheet

Children's single beds are often on lower, simpler frames with standard mattresses of 8 to 10 inches. Adult single beds in guest rooms or student accommodations may use a foam mattress that sits between 6 and 10 inches. Bunk beds almost always use standard single mattresses to keep the top bunk at a manageable height, so pocket depth is rarely an issue there.

If you have added a mattress topper to a single bed, measure the combined height of the mattress and topper before buying sheets. A 2-inch topper on a 10-inch mattress creates a 12-inch sleeping surface that will need a deeper pocket than the sheets you may already own.

Single Bedsheet Sizes in Centimetres

For shoppers more comfortable with metric measurements, here are the standard single bedsheet dimensions converted to centimetres.

Sheet Type	Inches	Centimetres
Single mattress	39 x 75	99 x 190
Fitted sheet	39 x 75	99 x 190
Flat sheet	66 x 96	168 x 244
Standard pillowcase	20 x 26 to 30	51 x 66 to 76

European bedding products sometimes list dimensions only in centimetres. A single fitted sheet listed as 90 cm x 190 cm is slightly wider than the Canadian standard of 99 cm, so check carefully when comparing European imports.

What Materials Work Best for Single Bedsheets

The material of your bedsheet affects comfort, durability, and how well the fitted sheet holds its shape over time. Here is a comparison of the most common materials available in Canadian bedding stores.

Material	Thread Count Range	Feel	Best For
Percale cotton	200 to 400	Crisp, cool	Warm sleepers, summer use
Sateen cotton	300 to 600	Silky, smooth	Cold sleepers, year-round
Linen	N/A (measured differently)	Textured, breathable	Hot sleepers, humid climates
Bamboo / viscose	250 to 400	Soft, cool	Sensitive skin, hot sleepers
Flannel	170 to 200 (GSM)	Soft, warm	Cold sleepers, winter use
Microfibre polyester	200 to 800	Smooth, wrinkle resistant	Budget-friendly, easy care

For children's single beds, soft microfibre and brushed cotton are popular choices because they are durable, easy to launder at high temperatures, and affordable enough to replace when needed. For adult guest rooms, percale cotton offers a hotel-like feel that most visitors appreciate.

Thread Count: What It Actually Means for Single Sheets

Thread count is the number of threads woven into one square inch of fabric, counting both vertical (warp) and horizontal (weft) threads. A higher thread count often indicates a softer, more durable fabric, but the relationship is not linear past a certain point.

For cotton sheets, the sweet spot for most sleepers is between 200 and 400. Below 200, the fabric can feel rough and pill quickly. Above 600, manufacturers often use multi-ply thread (two or three threads twisted together counted as one) to inflate the number, which does not necessarily improve the feel.

Linen sheets are not rated by thread count because the fibre is too thick. Flannel sheets use grams per square metre (GSM) instead. When comparing these materials to cotton, focus on feel and weight rather than a thread count number.

How Often to Wash Single Bedsheets

Single sheets on a bed that is used every night should be washed every one to two weeks. Sheets on a guest room bed that sees less frequent use can be washed every three to four weeks or after each guest visit.

The main reasons for regular washing are sweat, dead skin cells, and dust mites. A person sheds roughly 30,000 to 40,000 skin cells per hour, and many of those end up in your bedding. Dust mites feed on dead skin and are a common trigger for allergies and asthma. Regular washing at 60 degrees Celsius kills dust mites effectively.

For cotton and linen sheets, cold or warm water washing followed by a tumble dry on medium heat works well. High heat will shrink cotton over time, so avoid it unless you are specifically trying to kill allergens, in which case a hot wash is justified.

Our article on how often bedsheets should be washed covers the full breakdown of washing frequencies by situation.

Single Bedsheets for Bunk Beds and Daybeds

Bunk beds almost always use single mattresses, and standard single sheets fit perfectly. The main challenge with bunk beds is making the bed, particularly the top bunk, where there is limited room to manoeuvre.

A few practical tips for bunk bed bedding:

• Choose fitted sheets with elastic all the way around the perimeter rather than just at the corners. These stay in place better when someone climbs in and out repeatedly.
• Use a lighter flat sheet rather than a heavy blanket on the top bunk to make bed-making easier.
• Microfibre fitted sheets are more forgiving of dimensional variation and tend to stay on mattress corners better than stiff cotton.

Daybeds also use single mattresses but are often positioned against a wall on three sides, which affects how you make the bed. Choosing a fitted sheet with generous pocket depth prevents the sheet from pulling up when someone sits on the edge.

Single Bedsheet Sets: What Is Typically Included

A standard single bedsheet set in Canada typically includes:

• One fitted sheet (39 x 75 inches)
• One flat sheet (66 x 96 inches)
• One standard pillowcase (20 x 26 to 30 inches)

Some brands include two pillowcases even in a single set, which is useful if you use multiple pillows. Check the product listing carefully, as some lower-priced sets include only the fitted sheet and one pillowcase, omitting the flat sheet entirely.

If you prefer not to use a flat sheet and instead layer a duvet directly over the fitted sheet, you only need the fitted sheet and pillowcase. This is common in student accommodations and children's rooms where a simpler bed-making routine is practical.

Buying Single Bedsheets in Canada: Practical Advice

A few things worth knowing when buying single sheets in Canada:

First, Canadian consumer protection laws require textile products to list fibre content and country of manufacture. If a product does not list these, it may not meet Canadian labelling standards.

Second, watch for sheets listed in US sizing if you are shopping on cross-border websites. US twin sheets are the same as Canadian single sheets, but the flat sheet dimensions can vary slightly by brand.

Third, some Canadian retailers offer organic cotton sheets certified under the Global Organic Textile Standard (GOTS). If you are buying sheets for a child's bed or for someone with chemical sensitivities, GOTS certification confirms that the product was made without harmful dyes or finishes. Our article on organic cotton bedsheets explains what the certification covers.

Fourth, buying bedsheets in person at a bedding store lets you feel the actual fabric weight and texture before purchasing. Photos and thread count numbers on a website give you incomplete information. A 400 thread count sateen sheet from one manufacturer can feel completely different from a 400 thread count sateen from another because of yarn quality, weave tightness, and finishing processes.

How Bedsheet Size Connects to Your Mattress

Your bedsheet is only as comfortable as the mattress underneath it. A beautiful set of 400 thread count percale sheets on a worn-out mattress with pressure points will not give you a good night's sleep. Conversely, a high-quality mattress with sheets that slip off the corners every night will disrupt your rest just as effectively.

The single mattress standard of 39 by 75 inches covers a wide range of mattress types: coil spring, memory foam, latex, and hybrid models are all available in this size. If you are replacing a single mattress, our team can help you find the right option for your budget and sleeping needs. The bedsheet that goes on top is an important part of the equation, but the foundation matters most.
