Duvet sizing in Canada looks standard until you put a cover on an insert from a different brand and find two inches of empty fabric flapping at the corners. This chart page lists every standard Canadian duvet and cover size in inches and centimetres, explains why brands disagree on the same size label, and shows the overhang math for pairing a duvet with any Canadian mattress size.
In Canada, standard duvet sizes are roughly: Twin 66 x 86 inches, Double 78 x 86 inches, Queen 88 x 90 inches, and King 102 x 90 inches, though real dimensions vary by brand by two to four inches on the same size label. Always match your duvet cover to your insert's measured dimensions, not to your mattress size.
Hamuq makes a Canadian down duvet ($279 to $399 CAD) and a matching three-sided zipper duvet cover ($160 to $200 CAD) in Twin, Full, Queen, and King, both made in Canada.
Canadian duvet size chart (insert and cover)
A Canadian duvet is sized well beyond its mattress so the sides drape over the edge of the bed. The chart below shows the most common dimensions sold by Canadian retailers for each size label, alongside the mattress each is designed to cover. Because there is no enforced national standard, treat these as the centre of a range rather than a guarantee, and confirm the printed dimensions on any specific product before buying.
| Size | Typical duvet insert (in) | Typical duvet insert (cm) | Typical cover (in) | Fits mattress (in / cm) |
|---|---|---|---|---|
| Twin | 66 x 86 to 68 x 88 | 168 x 218 to 173 x 224 | 66 x 86 to 68 x 88 | 38 x 75 / 97 x 190 |
| Twin XL | 66 x 90 to 68 x 90 | 168 x 229 to 173 x 229 | 66 x 90 to 68 x 90 | 38 x 80 / 97 x 203 |
| Double / Full | 78 x 86 to 78 x 90 | 198 x 218 to 198 x 229 | 78 x 86 to 78 x 90 | 54 x 75 / 137 x 190 |
| Queen | 88 x 90 to 88 x 92 | 224 x 229 to 224 x 234 | 88 x 90 to 90 x 92 | 60 x 80 / 152 x 203 |
| King | 102 x 90 to 104 x 92 | 259 x 229 to 264 x 234 | 102 x 90 to 106 x 92 | 76 x 80 / 193 x 203 |
| California King | 104 x 96 to 107 x 98 | 264 x 244 to 272 x 249 | 104 x 96 to 107 x 98 | 72 x 84 / 183 x 213 |

Two size labels deserve special attention. Twin XL exists mainly for dorm and adjustable split-king setups, and many Canadian brands skip it entirely, selling only Twin. California King duvets are also sold by fewer Canadian brands; some retailers instead recommend an oversized queen for the narrower, longer Cal King mattress.
What size duvet do I need for my bed?
Buy the duvet size that matches your mattress size label, then confirm the actual inches give you at least 10 inches of drape per side. That single rule prevents most sizing mistakes. The mapping is direct: a queen mattress takes a queen duvet, a king takes a king. The judgment call is whether to size up for extra drape.
| Your mattress | Standard choice | Size up if |
|---|---|---|
| Twin (38 x 75 in) | Twin duvet | The bed is against a wall and you want one deep drape on the open side: Double |
| Twin XL (38 x 80 in) | Twin XL duvet, or Twin if XL is unavailable and 4 inches less length is acceptable | Rarely worth sizing up |
| Double / Full (54 x 75 in) | Double duvet | You want queen-level drape: Queen fits well on a Double |
| Queen (60 x 80 in) | Queen duvet | You share the bed and fight over coverage: King gives 22 inches per side |
| King (76 x 80 in) | King duvet | You want a near-floor hotel drape: oversized King (106 x 92 in) |
| California King (72 x 84 in) | Cal King duvet where available | Cal King is scarce in Canada: an oversized Queen or standard King also works, prioritizing length |
Mattress dimensions are the North American standard used across Canada. Verified July 2026.
Couples on a queen bed are the most common size-up case. A king duvet on a queen mattress adds roughly 7 inches of width per side over a queen duvet, which is usually enough to end the overnight tug-of-war. The trade-off is a longer drape that can pool near the floor on low platform frames.

Answer 3 quick questions and get your duvet and cover size.
Why your duvet cover does not fit your insert
The single biggest cause of a bad-fitting duvet cover is matching the cover to your mattress label instead of to your insert's measured dimensions. "Queen" is not one number in Canada. One brand's queen insert is 88 x 92 inches while another brand's queen cover is 88 x 90 inches, and the loose two inches of fabric is enough for the insert to shift, bunch at one end, and leave cold empty corners.
Three mechanics drive the mismatch:
Labels are marketing, dimensions are fact. There is no regulation forcing a Canadian "queen" duvet to be a specific size. Brands size their bedding to their own house standard, and premium brands deliberately oversize for a fuller drape.
Cross-border sizing. Canadian queen covers commonly run 88 x 90 inches, while American brands frequently sell queen covers at 88 x 88 or even 86 x 86 inches. Order a US-brand cover for a Canadian-standard insert and you can lose up to four inches of length.
Fill changes shape. A filled duvet lofts upward, which pulls its edges inward. Some manufacturers cut shells about two inches larger than the advertised finished size to compensate; others do not. Two duvets with the same printed size can measure differently once fluffed.
The fix takes one minute: lay your insert flat, measure width and length with a tape, and buy a cover whose printed dimensions match within about two inches. A cover the same size as the insert, or up to two inches larger, sits snug. Anything looser needs interior corner ties to hold the insert in place.
How duvet sizes differ by brand in Canada
Real listed dimensions from Canadian and cross-border bedding sellers show how far the same size label wanders. This table is why the measure-first rule exists.
| Seller type | Queen duvet / cover (in) | King duvet / cover (in) | Sizing style |
|---|---|---|---|
| Canadian standard (typical retail) | 88 x 90 | 102 x 90 | Baseline most charts quote |
| Canadian premium (oversized house cut) | 90 x 92 | 92 x 106 | Deliberately larger for fuller drape |
| Canadian specialty down makers | 88 x 90, plus XL Queen 96 x 98 | Standard King plus XL King options | Extra XL tier for Cal King and deep drape |
| Canadian insert-focused retail | 88 x 92 insert | 104 x 92 insert | Inserts cut slightly longer than covers |
| US brands sold into Canada | 88 x 88 or 86 x 86 | 104 x 90 to 107 x 98 | Squarer queen; check length carefully |
Dimension ranges compiled from published Canadian and US retailer size guides, July 2026. Individual products vary; always confirm the printed dimensions.
The practical reading: within Canada, queen dimensions cluster tightly around 88 to 90 inches wide, so mixing Canadian brands usually works. The risk concentrates in two places, US-brand covers that run square and short on a Canadian insert, and premium oversized duvets that swim inside a standard cover.
Duvet overhang math by mattress size
Overhang per side equals the duvet width minus the mattress width, divided by two. Ten to 14 inches per side is the range most beds need to look finished and keep sleepers covered; on a thick mattress, part of that drape is spent covering the mattress edge itself.
| Pairing | Width math (in) | Overhang per side | Verdict |
|---|---|---|---|
| Queen duvet (88) on Queen mattress (60) | (88 - 60) / 2 | 14 in / 36 cm | Standard, full drape |
| King duvet (102) on Queen mattress (60) | (102 - 60) / 2 | 21 in / 53 cm | Hotel drape, good for couples |
| King duvet (102) on King mattress (76) | (102 - 76) / 2 | 13 in / 33 cm | Standard, full drape |
| Double duvet (78) on Double mattress (54) | (78 - 54) / 2 | 12 in / 30 cm | Standard |
| Queen duvet (88) on Double mattress (54) | (88 - 54) / 2 | 17 in / 43 cm | Generous, works well |
| Twin duvet (66) on Twin mattress (38) | (66 - 38) / 2 | 14 in / 36 cm | Standard |
| King duvet (102) on Cal King mattress (72) | (102 - 72) / 2 | 15 in wide, but check length: 90 in duvet on an 84 in mattress leaves only 6 in total lengthwise | Width fine, length tight |
Widths use the common Canadian dimensions from the chart above. A 12 to 14 inch tall mattress consumes most of the first 12 to 14 inches of drape.
One number worth remembering from that last row: on a California King, length is the constraint, not width. The mattress is 84 inches long against a typical 90 to 92 inch duvet, so a restless sleeper pulls the foot of the bed bare quickly. That is why Cal King owners are often better served by a true Cal King duvet at 96 inches long than by sizing a standard King sideways.
Frame height changes the same math. On a low-profile platform such as a floating bed frame, the mattress surface sits closer to the floor, so a deep hotel drape reaches the floor sooner and can pool; a standard drape often looks better on low frames, while tall frames absorb an oversized duvet gracefully.

Hamuq Down Duvet and Easy Duvet Cover sizes
Hamuq sells the insert and the cover as matched pieces in the same four size labels, which removes the cross-brand mismatch problem entirely: a Hamuq queen cover is cut for the Hamuq queen duvet, so there is no cross-brand measuring to do. Both are made in Canada. Pick the size matching your mattress label below; if you need the exact finished measurements before ordering, Hamuq support at info@hamuq.com or the live chat on hamuq.com can confirm them for your order.
| Size | Fits mattress (in / cm) | Down Duvet (All Season 25 oz or Lightweight 19 oz) | Easy Duvet Cover (200 TC cotton, 3-sided zipper) |
|---|---|---|---|
| Twin | 39 x 75 / 99 x 190 | $279 CAD | $160 CAD |
| Full | 54 x 75 / 137 x 190 | $299 CAD | $170 CAD |
| Queen | 60 x 80 / 152 x 203 | $349 CAD | $180 CAD |
| King | 76 x 80 / 193 x 203 | $399 CAD | $200 CAD |

The Down Duvet is filled with 650 loft North American white down in a 300 thread count cotton shell with baffle box construction, and carries the DOWNMARK certification of the Down Association of Canada. It comes in two fills: All Season at 25 oz and Lightweight at 19 oz for warm sleepers or summer use. The Easy Duvet Cover is 200 thread count long-staple Portuguese cotton with a three-sided zipper, so the duvet drops in flat instead of being stuffed through a narrow opening, and it carries a 1-year limited warranty.
Possible downside: Hamuq does not make a Twin XL or California King duvet or cover. Twin XL sleepers should verify the Twin length works for their frame, and Cal King owners will find better length in a dedicated Cal King duvet from a specialty maker; our mattress size guide covers the Cal King dimensions in detail.

Frequently asked questions
What size is a queen duvet in Canada?
A queen duvet in Canada typically measures 88 x 90 inches (224 x 229 cm), with some brands cutting inserts to 88 x 92 inches and premium makers oversizing to 90 x 92 inches. It is designed to cover a 60 x 80 inch queen mattress with roughly 14 inches of drape per side. Always check the printed dimensions, since "queen" varies by brand.
Can I use a king duvet on a queen bed?
Yes, and many couples do it on purpose. A 102 inch wide king duvet on a 60 inch wide queen mattress gives about 21 inches of overhang per side instead of 14, which creates a hotel-style drape and ends fights over coverage. The trade-offs are extra fabric pooling on low frames and the need for a king cover to match.
Should my duvet cover be the same size as my duvet?
Yes, within about two inches. A cover the same size as the insert, or slightly larger, sits snug and keeps the fill evenly spread. A cover more than two inches larger lets the insert shift and bunch at one end, leaving empty cold corners. Measure the insert flat and match the cover to those numbers, not to your mattress label.
Are Canadian and US duvet sizes the same?
Close, but not identical, and the difference bites at queen. Canadian queen covers commonly run 88 x 90 inches while US brands often sell 88 x 88 or 86 x 86 inch queen covers. King sizes vary even more, from 102 x 90 up to 107 x 98 inches. When ordering from a US retailer, compare printed dimensions to your insert rather than trusting the size name.
What size duvet fits a California King mattress?
A California King duvet typically measures 104 x 96 to 107 x 98 inches, prioritizing the extra length of the 72 x 84 inch Cal King mattress. Fewer Canadian brands make this size; a standard King works for width but leaves the foot of the bed short, so Cal King owners should prioritize duvet length over width when substituting.
What is the difference between a duvet insert and a duvet cover?
The insert is the filled blanket itself, down or a down alternative inside a sewn shell, and the cover is the removable washable case that goes over it, like a pillowcase for your duvet. You buy them separately unless a brand bundles them, and the cover is what you wash regularly while the insert only needs occasional airing and professional cleaning.
Final word
Duvet sizing in Canada comes down to two habits: match the duvet to your mattress label, then match the cover to the insert's measured inches, never to the label alone. The chart above covers the standard ranges; the tape measure covers the rest. If you want to skip the matching problem entirely, the Hamuq Down Duvet and Easy Duvet Cover are cut for each other in every size.
