Choosing the Size of Your Down Duvet

Picking the right size is the easiest part of buying a down duvet. Duvet sizes correspond to bed sizes, so simply select a duvet which matches your bed. If you're unsure what size bed you have, take a look at the table below.

An undersized down duvet is a recipe for cold feet and exposed arms, but go too big and you might spend your nights feeling smothered. Better to be wrapped up comfortably in the perfect duvet. If you like the size of your current duvet, then just take a look at the tag and you will see which size you need.

Standard Sizes

Here’s a breakdown of duvet sizes corresponding with standard bed types:

Size Imperial (inches) Metric (cm)
Single 54 x 79 135 x 200
Double 79 x 79 200 x 200
King 91 x 87 230 x 220
Super King 102 x 87 260 x 220
Emperor 114 x 92 290 x 235

For a double bed, we recommend a down duvet that covers the entire width of your mattress, plus a few additional centimetres for good measure. If you have any doubt about the right duvet size, we advise you opt for one that’s a little larger than you need. What’s more, you should also take into consideration the width of your bed and whether or not the duvet will be used by more than one person —just to make sure you are both well covered at night!

Measuring Bed Dimensions

Since beds come in many different shapes and sizes, we recommend that you manually measure your bed before selecting your ideal duvet. Simply take a tape measure and note the length and width of the mattress.

Please note that if your mattress measures 200cm by 200cm and you order a duvet of this size, then it will fit the mattress precisely without draping over the sides of the bed. As such, if your dream duvet has extra room on the sides, then you will need to order a duvet which is slightly larger than your mattress.

Made to Measure

All of our duvets can be made to order, so feel free to place an order according to your personal specifications. There are no extra costs associated with a bespoke duvet, though it might take a little bit longer to manufacture. All duvets from the Dickenbergh Manufaktur Collection and the Falkenreck Collection are made to order, so you need not allow for extra delivery time with these brands.

Sewn-Through Construction or Baffle-Construction

Modern down duvets come in two main types: sewn-through and the baffle-box. Both varieties hold down in place and ensure the down is evenly distributed throughout the 'boxes', but they do so in slightly different ways.

The sewn-through construction is used in lighter duvets. The sides of the duvet are sewn together, promoting ventilation and making the duvet airier and cooler.

The baffle construction features vertical interior sidewalls in every chamber. This leads to less ventilation through the seams. They are therefore better at keeping you warm on cold nights.
