Reading Time: 8 minutes

Buying a blanket sounds simple until you get it home and realize it barely covers the mattress. Or worse, it drags on the floor like a tablecloth that lost its table. Getting the right blanket size matters more than most people think, and the sizing labels on packaging can be genuinely confusing.

After almost four decades helping Brantford families outfit their beds, we have seen every sizing mistake there is. The most common one? Assuming a "queen blanket" fits every queen mattress the same way. It does not, because mattress thickness varies from 8 inches to over 16 inches, and that changes how much drape you actually get.

This guide gives you the exact measurements for every standard blanket size, along with practical advice for choosing the right fit.

Complete Blanket Sizes Chart

Here are the standard blanket dimensions used in Canada. These measurements are for the blanket itself, laid flat, before any draping over the mattress edges.

A few things worth noting about these numbers. First, these are industry standard measurements. Individual brands may vary by an inch or two in either direction. Second, "overhang" assumes a standard 10-inch thick mattress. If your mattress is thicker or thinner, your actual drape will change.

Comforter vs Blanket vs Duvet Sizing

People often use these terms interchangeably, but the sizing differs slightly between product types.

Comforters and duvets are generally a few inches larger than flat blankets in the same size category. A queen comforter typically measures 92" x 96" compared to a queen blanket at 90" x 90". This extra width accommodates the loft and puffiness of the fill material. A thicker blanket material like down or synthetic fill takes up more surface area when it drapes over the edges.

Flat blankets, fleece blankets, and woven throws tend to follow the standard dimensions listed above more closely because they lie flat without significant loft.

How to Measure for the Right Blanket Size

Rather than guessing, you can measure your actual bed to figure out exactly what blanket dimensions you need. Brad, our senior consultant, walks customers through this all the time.

What is Good Overhang?

Overhang is how much blanket hangs past the edge of the mattress. Personal preference plays a big role here, but there are some practical guidelines.

Minimal overhang (8-10 inches) works for bunk beds, daybeds, and children's beds where you do not want fabric dragging. Standard overhang (12-16 inches) gives a clean, polished look on most beds. It is enough to tuck under slightly if you prefer that. Generous overhang (18-22 inches) creates a luxurious, hotel-style drape. You will need to size up from the standard blanket size for your mattress to achieve this look.

Accounting for Mattress Depth

This is where most people get tripped up. A 10-inch mattress and a 16-inch mattress both use "queen" blankets, but the thicker mattress eats up 6 more inches of blanket on every side. That is 12 inches less total drape.

If you sleep on a thicker mattress, like many of the models we carry at Mattress Miracle, including our Restonic collection which ranges from 12 to 15 inches deep, you may want to size up your blanket or look for "deep mattress" versions.

How Blanket Types Affect Sizing

Not all blankets behave the same way even when they share identical flat measurements. The type of blanket changes how it drapes, stretches, and covers.

Weighted Blankets

Weighted blankets follow completely different sizing rules. They should NOT hang over the edges of the mattress. A weighted blanket that drapes over the side can slide off during the night, which defeats its purpose and could be a safety concern for children or elderly sleepers.

For weighted blankets, choose one that covers just the top surface of the mattress. A queen mattress (60" x 80") works best with a weighted blanket around 60" x 80" or slightly smaller. The weight should be about 10% of the sleeper's body weight. Dorothy, our sleep specialist, often reminds customers that weighted blankets are sized to the person, not the bed.

Electric Blankets

Electric blankets also run slightly smaller than standard blankets in the same size category. A queen electric blanket is typically 84" x 90" rather than the standard 90" x 90". This is intentional. The heating elements need clearance from the edges, and the blanket should not be tucked tightly under the mattress, which could damage the wiring.

Fleece and Microfibre

These materials tend to stretch slightly with use. A new fleece blanket may feel just right, but after several washes and uses, it could stretch an inch or two in each direction. This is generally a benefit, as it gives you slightly more coverage over time.

Mattress Thickness and Overhang

Modern mattresses have gotten considerably thicker over the past two decades. What used to be a standard 8 to 10 inch mattress has become 12, 14, even 16 inches in many cases. Our Restonic ComfortCare Queen, for example, sits at about 12 inches, while the flagship Revive St. Charles is a full 15 inches.

If you have a mattress thicker than 12 inches, seriously consider buying a king-size blanket for your queen bed. The extra 18 inches of width (108" vs 90") gives you the drape you actually want. This is one of the most common recommendations Brad makes when customers mention their blankets feel too small.

Canadian vs American Blanket Sizing

Good news here. Canadian and American blanket sizes are essentially identical. Both countries use the same standard mattress dimensions (Twin, Double, Queen, King), and blankets sold in Canada follow the same size conventions.

Where you may notice differences is with European or UK imports. European sizing uses centimetres, and their standard bed sizes differ from North American ones. A European "double" is typically 135 cm x 190 cm (about 53" x 75"), which is close to but not exactly the same as a Canadian double (54" x 75"). The blankets sized for those beds will be slightly different.

Duvet Cover Sizing Note

If you use a duvet with a separate cover, make sure both are the same size designation. A queen duvet insert in a king cover will bunch up and shift around inside. A king insert in a queen cover will not fit properly and may stress the closures. This sounds obvious, but it is one of the most common bedding complaints we hear.

Choosing the Right Size for Your Bed

Here is a straightforward approach that works for most situations.

The Scandinavian method, two separate blankets on one bed, has become increasingly popular. Each person gets their own twin or double blanket, eliminating the nightly tug-of-war. It works especially well when partners have different temperature preferences. One person can use a lightweight cooling blanket while the other uses something heavier.

Caring for Different Sized Blankets

Blanket size affects how you wash and store them. Twin and double blankets fit comfortably in a standard home washing machine. Queen blankets are the upper limit for most residential washers. King blankets often need a commercial or front-loading machine with a larger drum.

If your blanket is too large for your home machine, a laundromat with commercial washers is your best option. Forcing an oversized blanket into a too-small washer prevents proper agitation and rinsing, which means the blanket will not actually get clean and detergent residue may remain in the fibres.
