Choose the Size of your Down Duvet

Choosing the correct size down duvet for your bed doesn't need to be difficult, although it’s important to give it some thought before buying one. It’s simply a case of taking into account the size of your bed and ordering a duvet that will give you plenty of coverage and comfort.

By following the advice on this page, you can rest easy knowing that your duvet will be the right size for your bed and the people in it.

Why is it important to buy the correct duvet size? If you choose a duvet that is too small, it won’t cover you well enough and you may get cold in the night. It also won’t look nice on your bed. On the other hand, if you choose a duvet that is too big, it may feel difficult to move freely underneath. It is certainly worth spending a small amount of time choosing the correct duvet size. Of course, if you are perfectly happy with the size of the duvet you are under at the moment, measure that one or look at the size tag. Life can be very simple sometimes.

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. Therefore it’s not a big deal to have your duvet made to measure. There are no extra costs associated with having your duvet made to measure, although it can sometimes take a little bit longer to manufacture. The Dickenbergh Manufaktur Collection and the Falkenreck Collection are both 100% handmade to order, so there is no extra delivery time for those 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.

Tog Rating

The standard indicator of how warm a duvet will keep you is the Tog rating, which is a measure of the insulating effectiveness of a duvet’s inner material (in our case, a mixture of down and feathers).

Duvets with a higher Tog rating are more able to keep you warm at night than a duvet with a lower Tog rating. In general we advise the following Tog rate per season. Of course the environment and your personal wishes can influence your decision for a certain Tog rating.

Summer duvet (4.5 tog)

SummerPlus duvet (6.0 tog)

Spring/Autumn duvet (9.0 tog)

Winter duvet (12.0 tog)

WinterPlus duvet (15.0 tog)


As important as the down, is the quality of the ticking. A good ticking not only holds all the down, it is also smooth enough to cover your body very precise so you will not be exposed to the cold. 

Have a Good Night

Choosing the right (size) down duvet might be something that requires some effort. But once you succeeded in choosing the right one, your duvet will reward your choice every night with a good night’s sleep. It keeps you warm and comfortable, time to snuggle up!
