How to use it

  1. Choose the width of your bed.
  2. Read the recommended duvet size.
  3. Use that same size when buying the cover.

What it works out and how

A duvet has to be considerably wider than the mattress so it hangs over the sides and nobody ends up uncovered. The tool applies the usual chart: 90 cm bed, 155 × 220 duvet; 105 and 135 beds, 200 × 200 duvet; 150 bed, 220 × 220 duvet; and 160 and 180 beds, 240 × 220 duvet.

Frequently asked questions

Can I use a larger duvet than recommended?

Yes. One size up gives more overhang, useful with a very deep mattress or when two people fight over the duvet.

Should the cover match the insert size?

Yes, the same size. A larger cover lets the insert slide around and a smaller one bunches it up.

Which weight should I choose?

It depends on bedroom temperature: light ones for summer or heated homes, and 250 to 300 g/m² or more for cold winters.
