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, just take a look at the tag and you will see which size you need.

Standard Sizes

Here’s a quick breakdown of duvet sizes in accordance with standard 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 suggest 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, it’s always advisable to go for one that’s a little larger than you need. What’s more, think carefully about width if the quilt is to be shared by more than one person – just to make sure you are all well covered during the night!

Measuring Bed Dimensions

As beds come in different shapes and sizes these days, it’s a good idea to manually measure your bed before selecting your ideal duvet. Simply take a tape measure and record the length and width of the top of the bed and the mattress.

Try to remember that if your mattress measures 200cm by 200cm and this is the quilt size you order, it will fit the mattress precisely with no additional drape over the edges. As such, if you would prefer the quilt to drape over the sides of the bed, you will need to order a slightly larger duvet than the mattress size.

Made to Measure

All our duvets are made upon order, so you can order a duvet which is made to measure. There are no extra costs associated with a bespoke duvet although it can sometimes take a little bit longer to manufacture. All duvets from the Dickenbergh Manufaktur Collection and the Falkenreck Collection are made to order, so there will be no extra delivery time for these brands. 

Sewn-through Construction or Baffle-construction

Modern down duvets come in two main types, the sewn-through duvet and the duvet with baffle-boxes. Both constructions help hold down in place and keep the same amount of down in all the boxes, they just do so in slightly different ways.

The sewn-through construction is used in the lighter duvets, because where the both sides of the duvet are sewn together, ventilation will appear, making the duvet more airy and cooler. 

The baffle construction features vertical interior sidewalls in every chamber. In this construction there is less ventilation at the seams, and is therefore better suited to keeping you warm on cold nights.
