Quick Answer: A queen comforter measures 86 to 90 inches wide by 90 to 100 inches long (218–229 cm × 229–254 cm). The extra length beyond the 80" mattress gives you 5 to 10 inches of overhang at the foot. For a pillow-top or thicker mattress, size up to the next width to ensure adequate side coverage.

Comforter sizing is less standardised than mattress sizing. A queen mattress has one fixed dimension: 60" × 80". A queen comforter can be 86", 88", or 90" wide depending on the manufacturer. That gap matters when you are lying in bed and want coverage that actually reaches the side you are sleeping on. This guide gives you the real numbers -- and explains what to measure before you buy.
Full Comforter Size Chart
All measurements below are width × length. "Width" is the side that runs across the bed; "length" runs from head to foot.
| Bed Size | Mattress (inches) | Comforter (inches) | Comforter (cm) | Side Overhang (each side) |
|---|---|---|---|---|
| Twin / Single | 38" × 75" | 60–70" × 86–90" | 152–178 × 218–229 cm | 11–16" per side |
| Twin XL | 38" × 80" | 66–68" × 90–100" | 168–173 × 229–254 cm | 14–15" per side |
| Full / Double | 54" × 75" | 74–84" × 86–96" | 188–213 × 218–244 cm | 10–15" per side |
| Queen | 60" × 80" | 86–90" × 90–100" | 218–229 × 229–254 cm | 13–15" per side |
| King | 76" × 80" | 102–108" × 86–100" | 259–274 × 218–254 cm | 13–16" per side |
| California King | 72" × 84" | 107–110" × 96–108" | 272–279 × 244–274 cm | 17–19" per side |
Queen Comforter Dimensions
The standard queen mattress in Canada measures 60 inches wide by 80 inches long (152 × 203 cm). A queen comforter is designed to overhang on all sides. The standard queen comforter size is 86 to 90 inches wide by 90 to 100 inches long.
That means on a standard queen mattress with no bed frame footprint:
| Measurement | At 86" Wide | At 90" Wide |
|---|---|---|
| Side overhang (each side) | 13" | 15" |
| Foot overhang (at 90" length) | 10" | 10" |
| Foot overhang (at 100" length) | 20" | 20" |
For a standard-height mattress (10–12"), 13–15" of side overhang reaches partway down to the box spring or bed frame. If you have a pillow-top mattress (14–16" thick) or want the comforter to reach the floor on a platform bed, you will want the wider end of the range -- or consider a king-size comforter on a queen bed.
Why Comforter Width Varies by Manufacturer
Unlike mattresses, which are regulated to fixed sizes, comforters are not standardised. A "queen" comforter from one brand may be 86" wide; another may be 92". The variance comes from different intended bed heights and cultural preferences. European brands often run narrower; North American brands typically run wider. When buying online, always check the product's listed dimensions rather than relying on the label alone.

King Comforter Dimensions
A standard king mattress is 76 inches wide by 80 inches long (193 × 203 cm). King comforters are made to match this larger footprint.
The standard king size comforter dimensions are 102 to 108 inches wide by 86 to 100 inches long (259–274 cm × 218–254 cm). The extra width is substantial -- at 108" wide on a 76" mattress, you have 16 inches of overhang on each side.
For a California King mattress (72" × 84"), look for comforters labelled "California King" or "Cal King" which typically run 107–110" wide and 96–108" long to accommodate the longer mattress. Using a standard king comforter on a California King bed leaves the foot of the mattress under-covered.
Brad, Owner, 40+ years of experience: "People buy a king mattress and grab a king comforter without checking. Then they come back saying it barely tucks in. King comforter widths vary by 6 inches between brands -- always check the product dimensions, not just the size label."
How to Choose the Right Comforter Size
Steps Before You Buy
- Measure your mattress height: Standard mattresses are 10-12" tall. Pillow-top models run 14-18". Every extra inch of mattress height reduces how far the comforter drops down the sides.
- Decide on your style: Do you want the comforter to tuck under the mattress (needs extra length) or drape loosely (standard size works)? Tucking requires at least 8-10" more than bare drape coverage.
- Check if you share the bed: Two people pulling the same comforter need more width. Many couples on queen beds buy a king comforter to reduce the "comforter tug" problem at night.
- Match the duvet insert to the cover: If you use a duvet cover, buy the insert and cover in the same stated size from the same brand when possible. A queen insert in a queen cover from different makers can bunch or shift.
Comforter vs Duvet: Which Do You Need?
In Canadian bedding retail, "comforter" and "duvet" are often used interchangeably, but they are not exactly the same thing.
| Feature | Comforter | Duvet |
|---|---|---|
| Construction | Filled insert sewn inside a fabric shell | Bare insert (requires a separate cover) |
| Washing | Wash the whole thing | Wash the removable cover; rarely wash the insert |
| Customisation | Fixed look | Swap covers for different styles |
| Cost | Lower upfront; one piece | Higher upfront; more flexible long-term |
Either way, the sizing logic is the same: the outer dimensions should extend 13-16" past each side of the mattress for practical coverage.

What size is a queen comforter?
A queen comforter is typically 86 to 90 inches wide and 90 to 100 inches long (218–229 cm × 229–254 cm). The variance between brands means you should always check the product's listed dimensions rather than relying on the size label alone. For a pillow-top mattress, aim for the wider end of the range.
Can I use a king comforter on a queen bed?
Yes, and many couples prefer it. A king comforter on a queen bed gives you an extra 8-10 inches of width, which reduces the "comforter tug" problem when two people share the bed. The extra fabric simply drapes further down the sides or can be tucked under for a neater look.
What are the dimensions of a king size comforter?
King comforters typically measure 102 to 108 inches wide by 86 to 100 inches long (259–274 cm × 218–254 cm). California King comforters run 107–110 inches wide and 96–108 inches long to accommodate the longer Cal King mattress (72" × 84").
Is a queen comforter the same as a queen duvet insert?
They should be the same size, but comforter and duvet insert sizing can vary between manufacturers. When buying a duvet cover and insert separately, it is best to buy them from the same brand or at least verify the listed dimensions match within 1-2 inches on each side.
How do I know if a comforter is too small for my bed?
If the comforter does not overhang at least 10-12 inches on each side when centred on the mattress, it is too small. You should also be able to pull one side up to your chin without exposing your partner on the other side. If your mattress is a pillow-top or extra-thick model, add 2-4 inches to your minimum width requirement.
