Size Guide
All measurements are in centimetres and follow standard UK bed sizing. Bedding can vary slightly between makers, so please also check the specifications on each product page. If you're between sizes or unsure, email hello@sovvn.com and a real person will help.
UK mattress & fitted sheet sizes
Our fitted sheets are cut to fit standard UK mattresses. Choose the size that matches your mattress.
| Size | UK mattress (W × L) | Also known as |
|---|---|---|
| Single | 90 × 190 cm | 3ft |
| Double | 135 × 190 cm | 4ft 6in |
| King | 150 × 200 cm | 5ft |
| Super King | 180 × 200 cm | 6ft |
Mattress depth: our fitted sheets comfortably fit mattresses up to approximately 30–34 cm deep. Measure your mattress from the top surface to the underside before ordering — the exact fitted depth is listed on each product page.
Flat sheet sizes
Generously cut for an easy tuck and a smooth, hotel-style finish.
| Size | Flat sheet (W × L) |
|---|---|
| Single | 180 × 260 cm |
| Double | 230 × 260 cm |
| King | 270 × 275 cm |
| Super King | 305 × 275 cm |
Duvet & duvet cover sizes
Your duvet cover should match the size of your duvet (not necessarily your mattress). Many people size up for extra drape and coverage.
| Size | Duvet / duvet cover (W × L) |
|---|---|
| Single | 135 × 200 cm |
| Double | 200 × 200 cm |
| King | 230 × 220 cm |
| Super King | 260 × 220 cm |
Tip: if you like a fuller, more luxurious drape — or share with a partner who pulls the covers — size up to the next duvet size.
Pillowcase sizes
Our Signature Pillowcases are a standard UK housewife fit, designed for everyday pillows.
| Style | Dimensions | Best for |
|---|---|---|
| Housewife (standard) | 50 × 75 cm | Everyday UK pillows — our Signature pair |
| Oxford | 50 × 75 cm + 5 cm border | A tailored, framed look |
| Square / Continental | 65 × 65 cm | Large European pillows & styling |
How to measure
- Mattress: measure width, length and depth (top to underside) to choose your fitted sheet.
- Duvet: measure your existing duvet, or match the size you usually buy.
- Pillows: most UK pillows are housewife size (50 × 75 cm).
