You’ve read our article on the many benefits of down duvets and are convinced you should buy a new duvet. However, are you confused by the multitude of duvet sizes available? Don’t worry, this complete guide will clear up all your doubts!

Understanding dimensions

An important point is that the dimensions of duvets and duvet covers are always in width x length format. To avoid any confusion, always use this structure (width x length) so that you don’t make a mistake when choosing your duvet and can better understand the item.

For example, a 240 x 220 cm duvet means 240 cm wide and 220 cm long.

Standard sizes: the detailed guide

The choice of size is generally based on the dimensions of your mattress. The aim? Cover your bed perfectly for a result that’s both aesthetical and functional.

Here’s a quick summary of the recommended sizes:

However, as there are different mattress lengths, this must also be taken into account when choosing the length of the duvet.

If your mattress is 210cm long, which is usually the case with Dutch mattresses, then we recommend that you choose a duvet that is at least 220cm long. If your mattress is 220cm long, which is generally the case with German mattresses or mattresses for tall people, then we recommend that you choose a duvet that is 240cm long.

Here’s a summary for longer mattresses:

Other aspects to take into account

Now that you have an idea of the standard sizes, we advise you to also take into account the following points to personalise your choice of duvet as much as possible.

• If you’re tall and your feet tend to stick out of the duvet, then think about getting a duvet long enough to cover you properly.
• If you tend to move around a lot in your sleep or you sleep in a double bed, having a wider duvet or, like the Scandinavian/Germanic way, taking two individual single duvets would allow you to disturb the other person less and have enough duvet for the night.
• For adult-size people who sleep with single duvets, we recommend 220 cm long duvets, meaning 140 x 220 cm or even 155 x 220 cm, which will give more comfort in length, and 155 cm wide duvets will give more comfort in width to avoid airstreams.
• If you wanted to buy a duvet for your teenager who has a 140 cm-wide bed, you might have been tempted to go for a 200 x 200 cm duvet, but if you want your child to keep their duvet for a few years, then you might consider a 240 x 220 cm duvet that will fit larger beds. However, you’ll need to keep in mind that the duvet will fall 50 cm to either side when there’s no one in the bed. You’ll also need to make sure that your child’s bed isn’t against the wall, in which case we recommend a 200 x 200 cm duvet.
• If you still want to keep your or your child’s IKEA-style Scandinavian duvet (150 x 200 cm), you can always get a duvet cover in the 140 x 200 cm size. There are two reasons why it’s better to choose a smaller size. The first is that if you take a size that’s too big, your duvet is likely to slip off and you won’t be properly covered. The second reason is that in a slightly smaller duvet cover, the duvet will be more secure, won’t move around and you’ll have the advantage of having a puffier duvet.
• For older duvets that are not part of the standard sizes or exotic duvets, we advise you to take a slightly smaller duvet cover size for the reasons mentioned in the previous point.
• Also, think about how you want your bed to look. The current trend is to use a duvet that goes down to the floor. We recommend that you pay attention to the height of your bed, because if it’s too low, the duvet is likely to drag along the floor, and you could step on it, which could damage it. So measuring the height of your bed before choosing your duvet size makes perfect sense. What’s more, if your bed is against a wall, the duvet will only have one side to fall on, so we advise you to choose a smaller duvet in this case.
• For duvet covers, the Kalani factories always take into account the fabric shrinkage rate in the first wash/dry. This means that after your first wash/dry, your duvet cover will be the right size for your duvet. We therefore recommend that you use the same size duvet cover as your duvet. The same applies to pillowcases, which should be chosen according to the actual size of your pillows, and mattress cover sheets, which should be chosen according to the size of your mattress.

And after the duvet?

Your choice of bed linen will help you to feel and sleep better, so after choosing the size of your duvet, it’s important to make the right choice of material and softness for your duvet cover and bed linen. It’s also important to choose a pillow that matches your sleeping position for optimum comfort and no neck or back pain. And for the fun part, depending on the mood you want your bedroom to have, take the time to choose the tones for your bedroom.

In conclusion, having a good duvet is a guarantee of quality sleep. That’s why we strongly advise you to take the time to see which one suits you best, so you can enjoy your nights even more! If in doubt, contact your Kalani advisor.
