Duvet Cover Sizes: Complete Guide

Duvet Cover

When it comes to getting the best sleep, a good night’s rest begins with great bedding! But if you’re confused about duvet cover sizing and want to better understand your king size from your queen size, we’ve got you covered. In the following article, we’re going to give you a complete rundown of the most common duvet cover sizes, their dimensions, and answer some commonly-posed questions on the subject - so let’s dive in!


What are Duvets?

First of all - what actually are duvets and why do we use them? Put simply, a duvet is a heavy blanket filled with either an organic or synthetic filling, designed to keep us warm when we sleep (or equally, to keep us cozy if we’re bundled up on the sofa with a cold.) Unlike blankets or quilts which are more lightweight and ideal for summer, duvets are most suitable for use in colder climates or during the winter months - although you’ll typically find duvets in hotel rooms all year round.


The Importance of a Duvet Cover

As you likely already know, duvets are typically white in colour, which is where duvet covers come in handy. A duvet cover not only adds an aesthetic dimension to your home, but also prevents your duvet insert from becoming soiled, stained, or even torn or damaged while in use. After all, we spend about one third of each day sleeping under our duvets, so having a protective layer in place is important when it comes to keeping your duvet insert in tip-top condition.


Understanding Duvet Cover Sizes

Just like pillows come in all different lengths and sizes, so do duvet covers! Duvets and covers are sized to fit standard frames for bed sizes, most notably:

  • Standard single
  • Twin size bed
  • Standard Double
  • Queen size bed
  • King size bed

But how do each of these sizes differ, and what are the measurements for each? Let’s take a look.


What size is a Queen Size Duvet?

The dimensions of queen size duvet in Canada are: 88 x 90 inches, or 225 x 230 in centimetres. This is designed to fit (and slightly overlap) the dimensions of a Canadian queen size mattress, which is 60 by 79 ½ inches, or 152.5 x 202 in centimetres. A queen duvet cover will tend to be a few inches larger than the duvet itself, but this may vary depending on the style of the cover.


What size is a King Size Duvet?

The dimensions of king size duvet in Canada are: 102 x 90 inches, or 260 by 230 in centimetres. This is designed to fit (and slightly overlap) the dimensions of a Canadian king size mattress, which is 76 x 79.5 in inches, or 193 x 202 in centimetres. Similarly to the queen duvet sizing, a king duvet cover set will usually be slightly larger than the king duvet itself, although this can fluctuate by brand and style.


What size is a standard double duvet cover in Canada?

The dimensions of standard double duvet in Canada are: 102 x 90 inches, or 260 by 230 in centimetres. This is designed to fit (and slightly overlap) the dimensions of a Canadian standard double mattress, which is 53 x 74.5 inches in inches, or 134.5 x 189 in centimetres.


What is the Canadian twin duvet size?

In Canada, the dimensions for a twin bed duvet are: 64 x 86 in inches, or 162 x 220 in centimetres, while the dimensions for a twin size mattress are 38 x 74.5 in inches, or 96.5 x 189 in centimetres.


Should I size up when buying a duvet cover?

There’s no need to size up when you’re buying a duvet cover - duvet covers tend to be slightly larger in order to accommodate the volume of your duvet insert; for example, while a queen size duvet measures 88 x 90 inches, most companies will make their queen size duvet covers slightly larger than this, so that the cover sits comfortably on the insert without bunching up. In short, sizing up will only mean that your duvet cover won’t fit properly, so always buy your duvet cover in the size that corresponds to your insert.


What's the difference between a quilt and a duvet?

A quilt tends to be a lighter material, and while it is thicker than a blanket due to its layer of batting (usually a natural or synthetic filling) it’s more lightweight than a duvet, and better suited to use in hotter climates or during the warmer months of the year.


What happens if your duvet cover is too big?

If your duvet cover is too big, your duvet insert is going to slide around inside the cover, which can be both uncomfortable and profoundly irritating when you’re trying to sleep! Put simply, when a duvet cover is too large for an insert, you won’t get even warmth or coverage, and your duvet could even end up folding over inside the cover. Plus, it’ll look uneven and lumpy when you make your bed, so to avoid this, always make sure to buy the correct duvet cover size.


The Bottom Line

Ultimately, while there might seem to be just a few inches of difference between certain duvet sizes, getting the right sized duvet cover can make all the difference to both your sleep, as well as the aesthetics of your bedroom.
