Complete Blankets Sizes Chart: All Dimensions in One Reference
Finding accurate blanket dimensions in one place is harder than it should be. Retailers use inconsistent labelling, some list only imperial measurements, others only metric, and the same size label can mean slightly different things between brands. This blankets sizes chart collects every standard blanket dimension in one organised reference, covering all types from baby to California king, in both inches and centimetres.

How to Calculate Overhang for Any Blanket Size
Overhang is how much the blanket extends beyond the mattress edge on each side. To calculate it:
- Take the blanket width minus the mattress width
- Divide by 2 for each side overhang
- Subtract the mattress height if you want to know how far the blanket drops below the mattress surface
Example for a queen bed with a standard queen blanket (90-inch wide blanket on a 60-inch wide mattress, 12-inch tall mattress):
- 90 minus 60 = 30 inches total overhang
- 30 divided by 2 = 15 inches per side
- 15 minus 12 (mattress height) = 3 inches hanging below the mattress edge
A result of 3 inches hanging below is minimal. If you want the blanket to drape to mid-frame or lower, you need either a wider blanket or an oversized queen (90 x 108 inches) to add length at the sides of a taller mattress.
Side Overhang by Blanket and Mattress Combination
| Blanket Size | Mattress Width (in) | Total Overhang (in) | Per Side (in) |
|---|---|---|---|
| Twin (66 in) | 38 | 28 | 14 |
| Full (80 in) | 54 | 26 | 13 |
| Queen (90 in) | 60 | 30 | 15 |
| King (108 in) | 76 | 32 | 16 |
| Cal King (102 in) | 72 | 30 | 15 |
| Queen blanket on King | 76 | 14 | 7 |
| King blanket on Queen | 60 | 48 | 24 |

Baby and Toddler Blanket Sizes
Baby blankets cover a wider size range than adult blankets because they serve different functions at different ages:
| Type | Dimensions (inches) | Use |
|---|---|---|
| Receiving blanket | 30 x 30 to 30 x 40 | Swaddling newborns |
| Security blanket | 14 x 14 to 18 x 18 | Comfort object for infants |
| Crib blanket | 36 x 46 to 45 x 60 | Toddlers 12 months and older |
| Stroller blanket | 30 x 35 to 36 x 46 | Pram, stroller, car seat use |
Important: the Canadian Paediatric Society advises against using loose blankets in cribs for infants under 12 months due to suffocation risks. Wearable blankets (sleep sacks) are the safe alternative.
Throw Blanket Sizes
| Type | Dimensions (inches) | Best For |
|---|---|---|
| Lap throw | 40 x 54 | Reading chair, small accent |
| Standard throw | 50 x 60 | Standard sofa |
| Large throw | 60 x 72 | Wide sofa, two people |
| Oversized throw | 60 x 80 | Sectional, couch napping |
Bed Blanket Sizes (Full Reference)
| Blanket Label | Standard Dimensions (in) | Fits Mattress | When to Size Up |
|---|---|---|---|
| Twin | 66 x 90 | 38 x 75 in | Tall mattress, foot tucker |
| Twin XL | 66 x 96 | 38 x 80 in | Tall person, dorm use |

Why Blanket Size Labels Are Not Always Consistent
Unlike mattresses, which adhere to standard North American dimensions, blankets do not have a regulatory size standard in Canada. Manufacturers set their own dimensions within a general range. This means a "queen blanket" from one brand may be 90 x 90 inches, while another brand's "queen blanket" measures 90 x 96 inches.
Always check the printed dimensions on the packaging rather than relying solely on the size label. This is especially important when:
- Shopping online where you cannot feel the product before buying
- Buying a blanket as a gift where you need accurate sizing
- Matching a blanket to a duvet cover or blanket cover you already own
- Replacing an existing blanket and expecting the same dimensions
How Blanket Size Affects Washing and Drying at Home
Larger blankets require larger machines. A standard home washing machine (top loader, 4.5 cubic feet capacity) can typically handle blankets up to full/double size. A queen or king blanket often requires a high-capacity washer (5+ cubic feet) or a commercial washer at a laundromat.
| Blanket Size | Approximate Weight (wet) | Machine Needed |
|---|---|---|
| Throw / Twin | 1-2 kg | Standard home machine (4.5 cu ft) |
| Full / Double | 2-3 kg | Standard or high-capacity home machine |
| Queen | 3-4.5 kg | High-capacity home machine (5+ cu ft) |
| King | 4.5-6 kg | High-capacity home machine or laundromat |
Blanket Size and Your Mattress: Making the Right Match
The most common mistake Canadian shoppers make is buying a blanket sized exactly to the mattress without accounting for mattress height. A 12-inch-tall queen mattress needs a blanket that covers the top (60 inches) plus both sides (12 x 2 = 24 inches) plus whatever drape they want below the mattress edge. That is a minimum blanket width of 84 to 90 inches just to clear the sides, with nothing draping below.
For a well-draped look, add 10 to 20 inches of desired drop per side. A queen mattress with 10 inches of desired drop on each side needs: 60 (mattress) + 24 (sides at 12-inch height) + 20 (10-inch drop each side) = 104 inches minimum. No standard queen blanket (90 inches) achieves that. An oversized queen (90 x 108 inches) comes close from a length perspective, but the 90-inch width still falls short for a draping width goal of 104 inches.
This is why many interior designers recommend sizing up one step, particularly for queen and king beds, when a full-coverage look is the goal.

Standard blanket sizes in Canada are: crib (30 by 40 inches), twin (66 by 90), double/full (80 by 90), queen (90 by 90), king (108 by 90), and California king (104 by 108), with throw blankets at 50 by 60 or 50 by 70 inches, though sizes vary by manufacturer and these should be treated as guidelines rather than exact standards. Mattress Miracle at 441½ West Street in Brantford carries mattresses in every standard Canadian size. Brad notes that blanket sizing confusion usually comes from the fact that there is no enforced standard, unlike mattress dimensions which are consistent across manufacturers. Always check actual dimensions on the packaging rather than relying on size labels, especially when mixing brands for sheets, blankets, and comforters. Call Talia at (519) 770-0001.
