What size duvet cover should you choose?

Winter is approaching and temperatures are dropping. For comfortable nights, choosing the right duvet cover size is essential. Bed dimensions, drape and mattress thickness: several criteria must be taken into account for a harmonious drape and a perfectly enveloped bed.

How do you choose the right duvet cover size?

The size of your duvet cover depends mainly on the dimensions of your bed and the desired drape. For an elegant, comfortable look, allow for a 30 to 40 cm overhang on each side.

Here are the generally recommended dimensions:

Bed size Duvet cover size
140 × 190/200 cm 200 × 200 cm or 240 × 220 cm
160 × 200 cm 240 × 220 cm
180 × 200 cm 260 × 240 cm or 280 × 240 cm


These dimensions are indicative and can be adjusted according to the thickness of your mattress, the presence of a mattress topper and the desired drape. A well-chosen cover complements your bedding elegantly and wraps you in softness night after night.

Mattress thickness: an essential criterion

Mattress thickness and the presence of a mattress topper directly affect the drape of your duvet. The thicker the bed, the more the side overhang may be reduced. Before choosing your duvet cover, remember to measure the total height of your bedding, from the bed base to the top of the mattress and mattress topper. A well-sized cover ensures a harmonious drape and optimal comfort, transforming your bedroom into a true cocoon of softness.

Mistakes to avoid when choosing your duvet cover

Choosing a duvet cover is not simply a matter of comparing dimensions. Orientation, size and fabric quality are all criteria to consider in order to ensure a harmonious drape and lasting comfort: 

  • Relying solely on dimensions: the order of width × length varies by brand. Check the dimensions and the opening direction before ordering.
  • Choosing a cover that is too tight: opt for a suitable size, or even slightly larger if in doubt, to preserve comfort.
  • Overlooking the material: the fabric influences softness, drape and hold. High-quality cotton satin offers a pleasant feel and an elegant finish.

Measure your bedding before buying

Before choosing your duvet cover, take the time to measure your bedding. Start by noting the dimensions of your current duvet, then measure the width and height of your mattress, including the mattress topper if you have one. These measurements will help you choose a cover suited to your bed and the desired drape.

Our advice:  use the dimensions of your current duvet to select a suitable cover, while checking the manufacturer's recommendations. An accurate measurement is the first step towards comfortable nights, wrapped in softness.
