Quick Answer: Yes, single beds and twin beds are the same size. Both measure 38 inches wide by 75 inches long (approximately 96 cm x 190 cm). The two names exist because the mattress industry uses "twin" in North America while UK and European retailers say "single." The dimensions are identical.

Walk into any Canadian mattress store and ask for a "single" or a "twin" and you will get the same mattress. The naming confusion comes from different retail traditions on different sides of the Atlantic, not from any real difference in size. If you grew up reading British books or IKEA catalogues, you learned one word. If you grew up watching American TV, you learned the other.
At Mattress Miracle in Brantford, customers ask about this distinction fairly often. The short answer is always the same: same mattress, two names. But the longer story of why we ended up with two names is genuinely interesting, and understanding it helps you shop with more confidence.
Single vs Twin: Are They the Same Size?
Yes. In Canada and the United States, a single mattress and a twin mattress measure the same: 38 inches wide by 75 inches long. That is roughly 96.5 cm x 190.5 cm. You will see both terms used on product pages, in store flyers, and in warehouse catalogues, sometimes interchangeably on the same page.
The confusion is purely linguistic. There is no industry body that officially retired one term in favour of the other, so both continue to circulate. You will find "single" used at IKEA Canada and The Brick. You will find "twin" used on most American brand sites and at many big-box retailers. Either label sends you to the same 38-inch-wide mattress.
| Name Used | Width | Length | Common In |
|---|---|---|---|
| Single | 38 in (96.5 cm) | 75 in (190.5 cm) | UK, Europe, IKEA, older Canadian retailers |
| Twin | 38 in (96.5 cm) | 75 in (190.5 cm) | USA, most Canadian mattress brands |
One thing worth knowing: a Twin XL is a different mattress. It shares the same 38-inch width but stretches to 80 inches long, making it 5 inches longer than a standard twin/single. Twin XL is popular in university residence rooms and for taller sleepers. If someone offers you "twin XL" sheets on a standard single frame, they will not fit properly.
Where Did the Word "Twin" Come From?
The name "twin" has a practical origin rooted in hotel room design. Through much of the early twentieth century, North American hotels began marketing rooms with "two twin beds" as an alternative to a room with one large double bed. The idea was that two adults could share a room without sharing a sleeping surface. This was especially common in business travel, where two colleagues might share accommodation.
The term "twin" was born from the notion of a matching pair. Two identical single beds placed side by side in one room became "twin beds," and eventually the individual mattress within that pair simply got labelled a "twin." The name stuck even when the bed was used alone, which is most of the time.
The Hotel Room Origins of "Twin" Bedding
North American hotels began standardising the "twin bed" room layout in the 1920s and 1930s. Travel industry publications of that era regularly advertised "rooms with twin beds" as a premium feature for business travellers sharing accommodation. Mattress manufacturers adopted the term to align with the hotel procurement market, and it filtered into residential retail by the mid-20th century. The word "twin" never referred to the mattress having a twin counterpart at home. It referred to hotel rooms where two matched beds were sold and installed together.
British and Commonwealth countries (including Canada, to a degree) continued to use "single" because the vocabulary came from the UK bedding tradition, where a single person's bed was simply called a single. As American retail influence grew in Canada post-World War II, "twin" began to appear in Canadian catalogues alongside "single," and both have coexisted ever since.
UK Single vs North American Twin Sizing
Here is where things get genuinely complicated: the UK single is not quite the same size as the North American twin, even though the names suggest they should be.
In the United Kingdom, a standard single mattress measures 90 cm x 190 cm, which works out to approximately 35.4 inches wide by 74.8 inches long. That is about 2.5 inches narrower than the Canadian twin/single at 38 inches (96.5 cm).
| Region | Name | Width (cm) | Width (in) | Length (cm) | Length (in) |
|---|---|---|---|---|---|
| Canada / USA | Twin / Single | 96.5 cm | 38 in | 190.5 cm | 75 in |
| United Kingdom | Single | 90 cm | 35.4 in | 190 cm | 74.8 in |
| Europe (general) | Single / 90x200 | 90 cm | 35.4 in | 200 cm | 78.7 in |
This matters practically if you are ordering bedding from a UK or European retailer. UK single sheets, duvets, and fitted sheets are cut for a 90 cm mattress. They will technically fit on a Canadian twin/single but they will be a touch snug and may not tuck properly on a platform bed. When shopping for bedding in Canada, always use Canadian sizing as your reference, not UK sizing.
A Note for Brantford Shoppers
If you have recently moved to Brantford from the UK or Europe and brought bedding from home, your European single sheets (90 cm) may feel slightly tight on a Canadian twin mattress. It is usually manageable, but if you are buying new bedding locally, every Canadian retailer including IKEA Canada sells sheets labelled for "twin/single" at 96.5 cm, not the UK 90 cm standard. Our team at Mattress Miracle is happy to clarify which size you need before you buy anything.

Who Fits a Single/Twin Mattress?
A twin mattress at 38 inches wide is designed for one sleeper. It works well for children from toddler age through their teenage years, for guest rooms where space is limited, and for adults living alone in small spaces like bachelor apartments, college residence rooms, or small primary bedrooms.
The 75-inch length is comfortable for people up to about 6 feet tall. If you are taller, a Twin XL at 80 inches gives you the extra room without adding to the bed's width. The width itself is the real constraint: 38 inches leaves limited space for a sleeping adult to move around, which is why couples almost always move to a double (54 inches wide) at minimum.
Who a Twin/Single Mattress Works Best For
- Children ages 3 to 12: Plenty of room to grow, and the smaller footprint fits most kids' bedrooms comfortably.
- Teenagers: Often works through high school, though tall teens may prefer Twin XL by age 15 or 16.
- Residence halls and college dorms: Most Ontario university residences use Twin XL. Confirm before buying.
- Small guest rooms: Two twin/single beds in a room is a practical and flexible setup for guests.
- Solo adults in smaller apartments: When space is the priority, a twin can work if you sleep alone and the room is compact.
Brad, Owner, 40+ years of experience: "Families often come in planning a twin for a growing child, which makes complete sense. My one suggestion is always to check the room size first. A twin fits comfortably in a 10x10 bedroom and leaves room for a desk and dresser. But if the room is 12x12 or larger, a double often fits just as easily and gives the kid more room as they get older. The price difference is usually modest."
If you are buying a twin mattress for a child who will grow into it, consider whether they are likely to need a bigger bed within a few years. A double (full) mattress at 54 inches wide costs modestly more and can last through the teen years and into early adulthood without being replaced.
Shopping for a Single/Twin in Canada
Canadian retailers use both terms, which can make online shopping confusing when you are searching for bedding or frames. Here is a practical breakdown of what you will encounter at major Canadian retailers.
| Retailer | Term Used | Notes |
|---|---|---|
| IKEA Canada | Single | IKEA uses European naming convention. Their "single" is the 96.5 cm Canadian standard. |
| The Brick | Twin / Single (mixed) | Both terms appear in their catalogues. Same size either way. |
| Leon's | Twin | Uses the American convention. Standard 38 x 75 inches. |
| Wayfair Canada | Twin | American platform, uses US sizing terminology throughout. |
| Sleep Country Canada | Twin | Uses "twin" consistently. 38 x 75 standard. |
| Mattress Miracle | Twin / Single | We use both interchangeably. Ask us anything in person at our Brantford showroom. |
The practical takeaway: do not worry about which word a retailer uses. Check the actual dimensions in the product listing. If it says 38 inches x 75 inches (or 96.5 cm x 190.5 cm), you have a standard Canadian twin/single, regardless of what name appears on the label.
Frames and Bedding: Do They Match?
Because twin and single refer to the same mattress size in Canada, frames, slats, box springs, and bedding labelled "twin" or "single" are interchangeable. A twin bed frame will hold a mattress sold as a "single," and twin XL sheets will not fit a standard twin (they are cut for the longer 80-inch mattress).
When buying a bed slat system for a twin, look for slats that span at least 38 inches internally. Most commercially available twin slat kits are sized for exactly this width. If you are building a platform bed frame from lumber, the mattress width of 38 inches becomes your interior measurement target.
Fitted Sheet Tip for Twin/Single Beds
Canadian fitted sheets labelled "twin" are cut for a 38 x 75 inch mattress with a pocket depth of 8 to 15 inches depending on the brand. If your mattress has a deep pillow top or a thick mattress topper, look for deep-pocket twin sheets (15 inches or more). The mattress width label does not change whether you call it twin or single, but pocket depth matters more than most shoppers expect.
Twin XL: The Exception Worth Knowing
The only size where terminology diverges meaningfully is Twin XL. A Twin XL is 38 inches wide by 80 inches long. There is no "Single XL" label in common use in Canada. If someone asks for a "single XL," they almost certainly mean Twin XL. Confirm the 80-inch length before purchase.
Ontario university residences including those in Hamilton, Waterloo, and Guelph typically use Twin XL mattresses in their residence rooms. If you are outfitting a student's dorm room, call the residence office and confirm the mattress size before buying bedding or a mattress topper. Buying twin-size fitted sheets for a Twin XL mattress is one of the most common errors we see come through our door in September.
Sleep Quality on a Twin/Single Mattress
Research published in the Journal of Chiropractic Medicine by Jacobson et al. (2008) found that mattress support quality had a significant effect on sleep quality and back pain, independent of mattress size. For a child or single adult sleeping alone, a well-constructed twin mattress at 38 inches provides adequate width for healthy sleeping positions including back, side, and stomach. The key variable is mattress construction (coil count, foam density, support zones) rather than the size label. A well-built twin will outperform a poor-quality queen for sleep quality every time.
What to Look for in a Twin Mattress
If you are buying a twin/single mattress in Canada, focus on these practical factors rather than the name printed on the label:
Coil count for innerspring mattresses: A twin mattress has less surface area than a queen, so coil counts will be proportionally lower. Our Restonic ComfortCare twin has 690 individually wrapped coils, which provides solid support across the mattress surface. Do not dismiss a twin mattress because the coil count looks low compared to a queen. Coil density (coils per square inch) matters more than raw count.
Flippability: For a child's mattress especially, a flippable dual-sided mattress can extend the lifespan significantly. Our Sleep In collection of Canadian-made flippable mattresses includes twin sizes that can be rotated and flipped, which spreads wear evenly over both sides and adds years to the mattress life.
Mattress protector: For children's beds in particular, a waterproof mattress protector is not optional. It protects the mattress warranty and prevents odour and staining that would otherwise degrade the foam layers or fabric. Ask about protectors when you buy the mattress.

Call 519-770-0001Are single beds and twin beds the same size?
Yes. In Canada, a single bed and a twin bed are both 38 inches wide by 75 inches long (96.5 cm x 190.5 cm). The two names come from different retail traditions. "Twin" originated in North American hotel industry vocabulary, while "single" came from the UK bedding tradition. Both names describe the same mattress size.
Is a UK single the same as a Canadian single/twin?
Not exactly. A UK single measures 90 cm wide (about 35.4 inches), which is roughly 2.5 inches narrower than the Canadian twin/single at 96.5 cm (38 inches). If you are buying UK bedding for a Canadian mattress, the sheets will fit but may feel slightly snug. Always check the dimensions in cm before ordering sheets from UK or European retailers.
Does it matter which term I use when shopping?
No, not in Canada. Both "single" and "twin" will get you to the same 38 x 75 inch mattress at any Canadian retailer. The only exception is IKEA, which uses European naming but still sells the Canadian-standard 96.5 cm width. Always confirm the actual dimensions in the product listing rather than relying on the label alone.
What is the difference between a twin and a Twin XL?
A twin/single measures 38 x 75 inches. A Twin XL measures 38 x 80 inches. The width is identical but the Twin XL is 5 inches longer, making it suitable for taller adults and most university residence rooms in Ontario. Bedding is not interchangeable between twin and Twin XL, so confirm your mattress length before buying sheets.
Can I find twin/single mattresses at Mattress Miracle in Brantford?
Yes. We carry twin/single mattresses from several collections including our Restonic ComfortCare line and our Canadian-made Sleep In flippable mattresses. You are welcome to stop by our showroom at 441 1/2 West Street in Brantford to see and feel the options in person. Our team does not work on commission, so you get straightforward advice.
What size are single duvets?
A single duvet is typically 135 cm x 200 cm (53 x 79 inches) and fits a twin or single bed (38 x 75 inches). For a fuller drape on the sides, some sleepers prefer a double duvet (200 x 200 cm) on a single bed. Single duvets are the most common size for children's rooms and guest beds in Canada.

Where can I find twin beds for sale in Brantford?
Mattress Miracle at 441 1/2 West Street in Brantford carries twin mattresses in a range of firmness levels and budgets. Twin beds (38 by 75 inches) are popular for children's rooms, guest rooms, and smaller apartments. For children specifically, the Canadian Chiropractic Association recommends a mattress firm enough to support spinal alignment without allowing the hips or shoulders to sink excessively - guidance that applies whether you are choosing a twin, single, or any size bed for a growing child. Talia, on our showroom floor, can help match the mattress to the sleeper's age, weight, and sleep position without sales pressure. Our Joliette Twin Bed Frame and Joliette Twin Bed Set are two Canadian-made options on the floor. White-glove delivery is available throughout Brantford and surrounding areas. Also see our twin bed headboards and frames guide.
What sheets fit a single bed?
Sheets labeled "twin" fit single beds - the terms are interchangeable in North America. A standard twin fitted sheet fits a mattress 38 inches wide by 75 inches long. If your single mattress has a topper or is particularly deep, look for twin sheets with a deep pocket (15 inches or more). Standard pocket depth is 9-12 inches. For single bed frames that use a longer twin XL mattress (38 by 80 inches), you will need twin XL sheets specifically - regular twin sheets will be too short. The Canadian Sleep Society notes that breathable natural-fibre sheets - cotton, linen, or bamboo - help regulate body temperature during sleep, which is especially relevant for children who tend to sleep warmer than adults. Our 100% Certified Organic Cotton Sheet Set comes in twin and is a popular pick for kids' rooms.
