Size of Blankets: The Complete Canadian Reference Guide for Every Bed

Getting the size of blankets right is one of those decisions that seems simple until you are standing in a store comparing labels or staring at a product page without a clear answer. Blanket sizing in Canada follows conventions that are largely shared with the United States, but there are enough variations across blanket types, bed sizes, and intended uses that a clear reference guide genuinely helps. This article covers standard sizes for every bed type, explains the difference between comforter, duvet, throw, and weighted blanket sizing, and gives you the practical information to buy with confidence.

Standard Blanket Sizes in Canada: Quick Reference Table

The following dimensions represent the most commonly available sizes across Canadian retailers. Minor variations between manufacturers do exist, so always confirm dimensions on the product listing before purchasing.

Bed Size	Mattress Dimensions (cm)	Recommended Flat Blanket (cm)	Recommended Comforter (cm)
Single / Twin	97 x 188	152 x 203	152–163 x 218–228
Twin XL	97 x 203	152 x 228	152–163 x 228–238
Double / Full	137 x 188	178–203 x 228	178–203 x 218–228
Queen	152 x 203	203–228 x 228–234	203–228 x 228–241
King	193 x 203	228–270 x 228–234	228–270 x 228–241
California King	183 x 213	228–270 x 241–254	228–270 x 241–254

Standard Blanket Sizes in Inches

Many Canadian retailers list blanket dimensions in inches, particularly when sourcing from US suppliers. This table provides the same reference data in imperial measurements:

Bed Size	Mattress Dimensions (inches)	Recommended Flat Blanket (inches)	Recommended Comforter (inches)
Single / Twin	38 x 74	60 x 80	60–64 x 86–90
Twin XL	38 x 80	60 x 90	60–64 x 90–94
Double / Full	54 x 74	70–80 x 90	70–80 x 86–90
Queen	60 x 80	80–90 x 90–92	80–90 x 90–95
King	76 x 80	90–106 x 90–92	90–106 x 90–95
California King	72 x 84	90–106 x 95–100	90–106 x 95���100

Why Blankets Are Bigger Than Mattresses

Every blanket size is significantly larger than the mattress it covers. This is intentional. The extra fabric serves three purposes:

1. Side drape: The blanket hangs down over the sides of the mattress, creating the covered look and preventing cold air from entering from the sides while you sleep.
2. Foot drape: The blanket extends beyond the foot of the mattress for aesthetics and to prevent the blanket from being pulled off the top when you move.
3. Fill compression allowance (for comforters): When you lie on a comforter, your body weight compresses the fill, pulling length from the foot end. Comforters are made longer to compensate for this effect.

The standard recommendation for side drape on a made bed is 25–35 cm (10–14 inches) on each side. For a queen mattress at 152 cm wide with 30 cm drape on each side, the minimum useful blanket width is 152 + 30 + 30 = 212 cm. This is why queen blankets are typically sold in the 203–228 cm width range.

Throw Blanket Sizes

Throw blankets are a distinct category from bed blankets. They are designed for use on sofas, chairs, or as an additional layer on a bed rather than as a primary bedding item. Standard throw blanket dimensions in Canada:

Throw Size Category	Dimensions (cm)	Dimensions (inches)	Typical Use
Small throw	107 x 127	42 x 50	Chair, lap blanket
Standard throw	127 x 152	50 x 60	Sofa, single person
Large throw	152 x 178	60 x 70	Sofa, two people or taller adults
Oversized throw	178 x 203	70 x 80	Sofa, oversized chair, or small bed

The most common throw blanket size in Canadian retail is 127 x 152 cm (50 x 60 inches). This is the size most frequently labelled simply as "throw" without a modifier. If a retailer lists "throw blanket" without dimensions, this is the size you can generally expect.

Weighted Blanket Sizes

Weighted blankets follow a different sizing logic than standard blankets. Because their therapeutic function depends on the weight distribution across the body, they are sized to cover the person rather than the bed. Standard weighted blanket sizes and weight recommendations:

Weighted Blanket Size	Dimensions (cm)	Recommended User Weight	Blanket Weight
Child	100 x 150	18–36 kg	2–4 kg
Individual (small)	122 x 183	45–68 kg	5–7 kg
Individual (standard)	152 x 203	68–90 kg	7–9 kg
Individual (large)	152 x 203	90+ kg	10–11 kg
Couples	203 x 228	Two people	9–11 kg

The general guideline is that a weighted blanket should weigh approximately 10% of the user's body weight. This is a starting point, not a firm rule, and many people prefer slightly heavier or lighter than the formula suggests. For couples sharing a weighted blanket, a larger size prevents the weight from concentrating on one person.

Duvet Insert Sizes vs. Duvet Cover Sizes

Duvets add another layer of sizing complexity because the insert and the cover are sized differently. A duvet cover is always slightly larger than the insert to allow for easy insertion and to prevent the insert from bunching. This means you cannot simply match the stated sizes and assume a perfect fit.

Bed Size	Duvet Insert (cm)	Duvet Cover (cm)	Difference
Single / Twin	140 x 200	145–155 x 205–215	Cover larger by 5–15 cm each direction
Double / Full	200 x 200	200–210 x 205–215	Cover slightly larger
Queen	210 x 210	210–220 x 210–220	Cover slightly larger
King	240 x 210	245–260 x 210–220	Cover wider, slightly taller

When purchasing a duvet and cover separately, always buy the cover that corresponds to the insert's stated size, not to your mattress size. A queen mattress does not necessarily take a queen duvet cover: it takes whatever size of duvet insert you have chosen, and the cover for that insert.

How Mattress Depth Changes Your Blanket Size Needs

Canadian mattresses have grown significantly deeper over the past two decades. Where a standard mattress was once 20–25 cm (8–10 inches) deep, pillow-top, euro-top, and thick memory foam mattresses now commonly reach 30–40 cm (12–16 inches) or more. This depth directly affects how much of a blanket is available for drape after covering the mattress profile.

For deep mattresses, sizing up by one category, for example from a queen blanket to a king-sized blanket for a queen bed, provides more practical side coverage. Hotels and upscale accommodation providers routinely do this to achieve the tucked, full-coverage look that is difficult to achieve with a standard-sized blanket on a deep mattress.

Electric Blanket Sizing in Canada

Electric blankets in Canada are typically available in these sizes:

Electric Blanket Size	Dimensions (cm)	Notes
Single / Twin	137–152 x 183–203	Single heat zone
Double / Full	152–178 x 183–203	Single or dual heat zone
Queen	152–178 x 203–228	Dual zone recommended for couples
King	203–228 x 203–228	Dual zone standard

Electric blankets are not intended to drape over bed edges or be tucked under a mattress, as this can damage the heating elements. Always follow the manufacturer's instructions on placement.

Choosing the Right Blanket for Your Specific Situation

Once you have the right size, the next decision is the fill and weight. The Canadian climate makes this a more significant decision than it would be in a milder region. A blanket suitable for a Toronto winter may be uncomfortably warm in a bedroom that runs consistently hot, even in January.

Some useful starting points:

• If you sleep warm: lightweight cotton, bamboo, or microfibre blankets with breathable weave structures
• If you sleep cool: down or down-alternative duvets with a higher fill power, or wool blankets for cold-climate use
• If you share a bed with a partner who has different temperature preferences: a dual-zone comforter or two separate blankets of different weights is more practical than a single shared blanket
• If allergies are a concern: down-alternative fills, synthetic fills, and certified OEKO-TEX bedding reduce allergen exposure

Frequently Asked Questions

What are the standard blanket sizes available in Canada?

Standard blanket sizes in Canada follow the same conventions as the United States. The main sizes are single/twin (approximately 152 x 203 cm), double/full (approximately 178–203 x 228 cm), queen (approximately 203–228 x 228–234 cm), king (approximately 228–270 x 228–234 cm), and California king (approximately 228–270 x 241–254 cm). Throw blankets are typically 127 x 152 cm.

Why does a queen blanket not fit a queen mattress exactly?

It does not fit exactly by design. Blankets are made significantly larger than the mattress to provide drape over the sides and foot. A blanket that exactly matches the mattress dimensions would leave the sides of the bed exposed and would be too short when the fill compresses under body weight.

Should I size up my blanket if I have a deep mattress?

Yes. If your mattress is 30 cm deep or more, the extra depth uses up what would otherwise be side drape. Sizing up by one category (for example, choosing a king-sized blanket for a queen bed) gives you the coverage you would lose to a deep mattress profile.

What is the difference between a comforter and a duvet?

A comforter is a single, sewn unit containing fill stitched in place and finished with a fabric shell. It is used on its own. A duvet is a fill-only insert designed to be used inside a removable, washable cover. Duvets are easier to wash because you launder the cover rather than the entire assembly. The sizing conventions for each differ slightly.

How do I know if a blanket is big enough for my bed?

Measure your mattress width and depth. The blanket should be wide enough to cover the mattress width plus twice the mattress depth, plus however much additional drape you want on each side (typically 15–30 cm). For the length, add the mattress length plus the full depth at the foot, plus 30–45 cm at the top for pillow tuck-in if desired.

Are Canadian blanket sizes different from UK sizes?

Yes. UK single blankets are typically 135 x 200 cm, compared to the Canadian standard of approximately 152 x 203 cm. UK king blankets are also narrower than Canadian king blankets. When purchasing from UK-based retailers or brand websites, confirm the stated dimensions rather than relying on the size label alone.
