Quick Answer: Yes, twin beds and single beds are the same size. Both measure 38 inches wide by 75 inches long (96.5 x 190.5 cm) in Canada. The difference is purely a label. "Single" appears on products at IKEA Canada and The Brick; "twin" appears on US-brand products and at most Canadian mattress specialists. Same mattress, two names.

If you have ever stood in a mattress aisle wondering whether "single" and "twin" refer to different mattresses, you are not alone. The terminology is genuinely inconsistent across Canadian retailers, and that inconsistency creates real confusion when you are trying to buy bedding, a bed frame, or a replacement mattress.
The good news is that the answer is simple once you know it: they are the same. The practical complexity is in knowing which stores use which word, and why, so you can shop efficiently without second-guessing every label.
Confirmed: Same Dimensions
In Canada, a twin mattress and a single mattress are the same product. The standard dimensions are:
| Term | Width (inches) | Length (inches) | Width (cm) | Length (cm) |
|---|---|---|---|---|
| Single | 38 in | 75 in | 96.5 cm | 190.5 cm |
| Twin | 38 in | 75 in | 96.5 cm | 190.5 cm |
There is no product difference. A mattress sold as "single" at IKEA and a mattress sold as "twin" at Mattress Miracle will measure the same and accept the same fitted sheet. Bed frames labelled "single" will hold a mattress labelled "twin" without modification.
The only size where you need to pay careful attention is Twin XL. A Twin XL is 38 inches wide (same as twin/single) but 80 inches long instead of 75 inches. There is no "Single XL" in common Canadian retail use. Twin XL bedding will not fit a standard twin/single mattress and vice versa. Always confirm whether you need standard (75 inches) or XL (80 inches) length before buying sheets or a mattress topper.
Where You See "Single" on Canadian Labels
The word "single" appears most often at retailers with European roots or older Canadian retail traditions. Here is where you are likely to encounter it:
Retailers That Use "Single"
- IKEA Canada: IKEA uses European naming conventions across all its markets. Their mattresses, bed frames, sheets, and duvet covers are all labelled "single" for the 96.5 cm width. This is the most common source of confusion for Canadians, since IKEA is enormously popular and its naming convention does not match most other Canadian retailers.
- The Brick: The Brick uses both "single" and "twin" on different products. You will see "single" on their older catalogue lines and "twin" on their newer American-brand inventory. Both refer to the same 38 x 75 inch size.
- Hudson's Bay (The Bay): Their bedding department often uses "single" in the traditional Canadian sense. This is consistent with older Canadian retail vocabulary that predates the widespread adoption of American mattress industry terminology.
- Older Canadian mattress brands: Some Canadian-made mattress lines still print "single" on their labels, particularly brands that have been manufacturing in Canada since before the 1980s.
The "single" naming in Canada largely traces back to British retail influence. Canada's retail vocabulary was shaped heavily by UK conventions in the early 20th century, and "single" was the standard word for a one-person bed. That usage persisted in some retail channels while "twin" took over in others.
What You Will See at Mattress Miracle
At our Brantford showroom, we use both terms depending on the product line. Our Canadian-made Sleep In mattresses use "single" on some of their labels, while our Restonic line uses "twin." In conversation, our team uses both interchangeably. If you ask for a single or a twin, you will get the same answer and the same mattress to try. What matters is whether the 38-inch width works for the sleeper and the room.

Where You See "Twin" on Canadian Labels
"Twin" is now the dominant term in most of the Canadian mattress market, particularly at retailers that carry American brands or that have adopted American retail conventions. You will encounter it at:
Retailers That Use "Twin"
- Sleep Country Canada: Canada's largest mattress chain uses "twin" consistently across its product catalogue. This includes their in-house brands and third-party labels.
- Leon's: Uses "twin" as the standard term. Their American-brand partnerships (Sealy, Simmons, Serta) all use US terminology.
- Wayfair Canada: An American platform with American terminology throughout. Everything that is 38 x 75 inches is labelled "twin."
- Amazon Canada: Primarily lists products using "twin" because most sellers on the platform are American or use American sizing conventions.
- Costco Canada: Uses "twin" on mattresses and bedding sets. Their private-label Kirkland bedding and most of their mattress brands follow American convention.
- Restonic and other US-origin mattress brands: All use "twin" regardless of which country they are sold in.
"Twin" became dominant in Canadian retail through the influence of American brands entering the Canadian market, American-style big-box retail, and American streaming and media culture that normalised the term for younger Canadian shoppers. It did not replace "single" entirely, but it became the more common term by the early 2000s.
Why Terminology Matters for Bedding Purchases
A 2019 survey by the Sleep Foundation found that incorrect sheet sizing was one of the top ten most common bedding purchase errors among North American consumers. In Canada specifically, the single/twin naming inconsistency contributes to this problem when shoppers buy bedding at one retailer (labelled "single") and a frame at another (labelled "twin"), then worry whether the products will be compatible. They will. The real sizing error to watch for is confusing standard twin (75 inches long) with Twin XL (80 inches long), since those two lengths do not share bedding.
Practical Shopping Guide
Here is the simplest possible guide to navigating the single/twin naming confusion when shopping in Canada:
Shopping Rules for Twin/Single Beds
- Rule 1: Check the dimensions, not the label. If a product says 38 inches (or 96-97 cm) wide and 75 inches (or 190-191 cm) long, it is a standard twin/single. Buy it.
- Rule 2: Twin and single bedding are interchangeable. A sheet labelled "twin" fits a mattress labelled "single" and vice versa, as long as both are the 75-inch standard length.
- Rule 3: Twin XL is a different product. Never buy Twin XL bedding for a standard twin/single mattress or bed frame. The 5-inch length difference means fitted sheets will not stay on.
- Rule 4: IKEA uses European sizing but Canadian standard dimensions. IKEA Canada's "single" mattresses are 96.5 cm wide, the same as any Canadian twin. IKEA single bedding (sheets, duvet covers) also fits standard Canadian twin mattresses.
- Rule 5: Frames labelled either way work. A bed frame labelled "twin" will hold a mattress labelled "single." The internal dimensions are the same. If in doubt, measure the interior frame width and confirm it is 38 inches (96.5 cm).
If you are buying a complete bed setup (mattress, frame, sheets, protector) and sourcing from different retailers, this guide should prevent any compatibility issues. You can mix and match single-labelled products from one store with twin-labelled products from another without issue.
Navigating IKEA Single Mattresses with Other Brands
One specific combination that comes up regularly: buying an IKEA bed frame (labelled "single") and pairing it with a mattress from a Canadian mattress specialist that labels it "twin." This is completely fine. The IKEA single frame and any Canadian twin mattress share the same 38-inch width. The mattress will fit the frame.
What to double-check with IKEA frames: some IKEA bed frames have specific slat spacing requirements that affect the mattress warranty of certain foam or memory foam products. If you are buying a foam mattress to place in an IKEA frame, read the mattress warranty terms. This is about slat spacing, not the twin/single naming distinction.
You can read more about matching mattresses to bed frames in our guide to twin bed slats and foundation requirements.
Bedding and Frame Compatibility
Sheets, duvets, fitted sheets, mattress protectors, and toppers are all interchangeable between "single" and "twin" labelled products in Canada, provided the length is the same (75 inches standard or 80 inches XL).
| Bedding Item | "Single" Labelled Fits "Twin" Mattress? | "Twin" Labelled Fits "Single" Mattress? | Notes |
|---|---|---|---|
| Fitted sheet | Yes | Yes | Check pocket depth for thick mattresses |
| Flat sheet | Yes | Yes | Width overhang may vary slightly by brand |
| Duvet / comforter | Yes | Yes | Twin duvets typically 66 x 88 in |
| Mattress protector | Yes | Yes | Check fit for pillow-top mattresses |
| Mattress topper | Yes | Yes | Confirm 38 x 75 in vs 38 x 80 in for XL |
| Bed frame | Yes | Yes | Internal width is always 38 inches |
One thing to check when buying fitted sheets: pocket depth. A standard fitted sheet has a pocket depth of 8 to 12 inches. If your mattress has a thick pillow top or you are adding a topper, the total mattress depth may exceed that. Look for "deep pocket" fitted sheets (15 inches or more) if your mattress plus topper exceeds 12 inches in depth. This applies equally to twin and single labelled sheets.
Talia, Showroom Specialist: "The question I get most often from customers who have just bought a new mattress is whether their existing IKEA single sheets will fit. The answer is always yes for a standard twin mattress. Where we sometimes see a problem is with very deep mattresses (over 13 inches) and standard-depth fitted sheets. If someone has a new mattress with a thick pillow top, I suggest grabbing a deep-pocket fitted sheet before assuming the old sheets will work."
What About Box Springs and Foundations?
Box springs and platform foundations labelled "twin" or "single" are also interchangeable. They are both sized to accommodate a 38-inch wide mattress. If you are using a slatted bed base from IKEA (labelled "single") under a mattress from a Canadian mattress store (labelled "twin"), the dimensions match.
Platform beds and slatted bases from IKEA do not always include a centre support rail in the twin/single size, which can affect long-term mattress support for heavier sleepers. This is worth checking regardless of which term the retailer uses. For children's beds, a solid or closely slatted base is recommended; our team at Mattress Miracle can advise on appropriate foundations for any mattress we sell.

Buying a Twin/Single for a Child? Consider Flippable.
For children's beds especially, a flippable dual-sided mattress extends the product life considerably. Most children's mattresses are used through multiple growth stages, and the ability to flip the mattress distributes wear evenly across both surfaces. Our Canadian-made Sleep In mattresses come in twin size and are designed to be flipped, which is why they carry a stronger long-term value than non-flippable alternatives at a similar price point.

Are twin beds and single beds the same?
Yes. In Canada, twin beds and single beds are exactly the same size: 38 inches wide by 75 inches long (96.5 cm x 190.5 cm). The two terms come from different retail traditions. "Single" originated in British and Commonwealth retail vocabulary. "Twin" came from North American hotel industry usage in the mid-20th century. Both now circulate in Canadian retail and refer to the same mattress size.
Why does IKEA say "single" when other stores say "twin"?
IKEA operates globally and uses European naming conventions throughout its product range. In Europe, a one-person bed is a "single" (usually 90 cm wide in the UK, but IKEA Canada stocks the North American 96.5 cm/38-inch standard). Other Canadian retailers have adopted American terminology where "twin" is the standard word for the same size. Both terms at IKEA Canada and other Canadian stores refer to the same 38 x 75 inch mattress.
Can I use IKEA single sheets on a twin mattress from another store?
Yes. IKEA single sheets sold in Canada are cut for a 96.5 cm (38-inch) wide mattress. Any Canadian twin mattress is also 38 inches wide. The sheets are fully compatible. The only scenario where they might not fit is if the mattress is unusually deep and the sheet's pocket depth is insufficient, but that is a depth issue, not a single-versus-twin issue.
Is Twin XL the same as a single?
No. Twin XL is 38 inches wide (the same as a standard twin/single) but 80 inches long instead of 75 inches. A Twin XL mattress is 5 inches longer than a standard twin/single. Twin XL bedding will not fit a standard twin/single mattress, and standard twin/single bedding will not stay on a Twin XL mattress. Always confirm the length (75 or 80 inches) before buying sheets or a topper.
