Which duvet size for which bed?
A duvet that's too small lets cold air in at the sides; one that's too big trails on the floor. Here's how to pick the right one in 2 minutes.
The golden rule: bed width + 40 to 80 cm
A duvet should hang over the mattress on each side, so it still covers you when you turn over, and come down far enough to stop draughts. The simple rule: duvet width = mattress width + 40 to 80 cm, which gives 20 to 40 cm of overhang on each side.
For length, 200 cm is enough for most standard 190 or 200 cm beds. If you're taller than about 6ft 1in (1.85 m), go for the 240 cm length.
The size chart
Our duvets come in European sizes, so the labels won't match UK duvet sizes exactly. Here's how each one fits a UK bed.
| Your bed | Recommended duvet | Overhang per side |
|---|---|---|
| UK single, 90 × 190 cm | 135 × 200 cm | 22 cm |
| UK double, 135 × 190 cm | 200 × 200 cm | 32 cm |
| UK king, 150 × 200 cm | 200 × 200 cm, or 220 × 240 cm for more overhang | 25 cm, or 35 cm |
| UK super king, 180 × 200 cm | 220 × 240 cm | 20 cm |
Fitted sheets and toppers
Our fitted sheets and mattress toppers also come in European sizes. Here's honestly how they sit on a UK mattress.
| Our size | Your UK bed | How it fits |
|---|---|---|
| 90 × 190 cm | Single, 90 × 190 cm | Exact fit |
| 140 × 190 cm | Double, 135 × 190 cm | 5 cm wider than your mattress: it fits, with a little extra room |
| 160 × 200 cm | King, 150 × 200 cm | 10 cm wider than your mattress: it fits, but sits a little looser |
| 180 × 200 cm | Super king, 180 × 200 cm | Exact fit |
Pillows and pillowcases: 50 × 70 cm
Our pillows and pillowcases measure 50 × 70 cm. The standard UK pillow is 50 × 75 cm, so they're 5 cm shorter. Our pillowcases are made for our pillows: on a standard 50 × 75 cm UK pillow, they'll be 5 cm too short, so the end of the pillow may peek out.
4 times you should size up
- There are two of you and one of you steals the duvet. A few extra centimetres on each side put an end to the night-time tug of war.
- Your mattress is deep (more than 25 cm, about 10 in, or with a topper): it uses up some of the overhang.
- You like to wrap yourself up in the duvet or sleep curled up on your side.
- You want a hotel-bed look, with the duvet falling almost to the base of the bed.
Measure your bed in 30 seconds
- Measure the width of the mattress, edge to edge (90, 135, 150 or 180 cm in most UK homes).
- Measure its depth, including any topper.
- Check the chart, and go up a size if the depth is over 25 cm.
