Fitted Sheet Size Guide
A fitted sheet needs to match two things: the width and length of the mattress top, and the depth at the side. Pick the size that matches width x length, then a corner depth at least as deep as your mattress (plus any topper). Our sheets use European sizes.
Standard UK and Irish mattresses
| Your mattress | Usually measures | Look for a sheet of |
|---|---|---|
| Single | 90 x 190 cm | 90 x 190 or 90 x 200 cm |
| Small double | 120 x 190 cm | 120 x 200 cm |
| Double | 135 x 190 cm | 140 x 190 or 140 x 200 cm |
| King | 150 x 200 cm | 150 x 200 or 160 x 200 cm |
| Super king | 180 x 200 cm | 180 x 200 cm |
A sheet that is a few centimetres larger than the mattress still fits; a smaller one will not. Some sheets cover a range, for example 160–180 x 200–220 cm. The product page shows the exact range for each size.

- Measure the depth at the side of the mattress. Add the topper if you use one.
- Choose the size that matches width x length, with a corner depth at least as deep as step 2.
