Got Double Bed Sheet Questions? We've Got Answers
UK double bed bedding from Belledorm follows the standard dimensions used across the British bedding industry, with fitted sheet depth varying depending on your mattress.
| Product | Standard UK Size |
|---|---|
| Fitted sheet | 135cm x 190cm (4ft 6in x 6ft 3in) |
| Flat sheet | 230cm x 275cm |
| Duvet cover | 200cm x 200cm |
Fitted sheets are available in three depths: standard 30cm (12 inches) for mattresses up to 22cm deep, extra deep 38cm (15 inches) for mattresses up to 30cm including those with toppers, and ultra deep 46cm (18 inches) for the deepest luxury and adjustable mattresses. Always measure your total mattress depth, including any topper or protector, before selecting a fitted sheet depth.
A standard Belledorm double fitted sheet (135cm x 190cm) fits a UK double mattress measuring 135cm wide by 190cm long, the most common shared bed size in the UK, found in the majority of couples' beds, guest rooms, and rental properties.
The fitted sheet's length and width dimensions are fixed to the mattress size. What varies is the depth, the box measurement that wraps under the mattress edge. Belledorm offers double fitted sheets in 30cm (standard), 38cm (extra deep), and 46cm (ultra deep) depths to accommodate mattresses from basic 15cm models through to 35cm+ pocket sprung mattresses with toppers. If you are buying for a small double mattress (120cm wide), a standard double sheet will not fit correctly, check the small double 4ft range instead.
A UK double bed measures 135cm x 190cm (4ft 6in x 6ft 3in). A king size measures 150cm x 200cm (5ft x 6ft 6in), 15cm wider and 10cm longer. The two sizes use different fitted sheets, flat sheets, and duvet covers, none of which are interchangeable.
The additional 15cm width of a king size makes a meaningful practical difference for two adults sharing, each person gains approximately 7.5cm more sleeping space. The 10cm extra length is also significant for taller adults over 6ft. A double fitted sheet will not stretch to fit a king size mattress and will pull free from the corners. If you are unsure which size your mattress is, measure the width: 135cm is double, 150cm is king size, 180cm is super king.
A double bed (135cm x 190cm) accommodates two adults and remains the most common shared bed size in UK homes. Each person has approximately 67.5cm of sleeping width, comfortable for couples who sleep close together, though noticeably less spacious than a king size (75cm per person).
Double beds work well in smaller bedrooms and rental properties where floor space is limited, and are a practical choice for guest rooms. For couples who prefer more room to move independently, or for adults over 6ft where the 190cm length may feel restrictive, a king size (150cm x 200cm) is a more comfortable long-term alternative. Belledorm's double sheet range covers 121 products across all fabrics and depths, from Basics Polycotton from £10.50 through to 1200TC Cotton Sateen.
To fully dress a double bed, you need a fitted sheet, a duvet cover, and at least two pillowcases. A flat sheet is optional but recommended for a layered or hotel-style setup.
The complete double bed bedding list:
- Fitted sheet (135cm x 190cm) - in your chosen depth: 30cm, 38cm, or 46cm
- Duvet cover (200cm x 200cm) - sized for a double duvet
- Pillowcases - standard UK pillow is 48cm x 74cm; two for a double bed
- Flat sheet (230cm x 275cm) - optional, used between the fitted sheet and duvet
- Mattress protector (135cm x 190cm) - recommended to extend mattress life and add a hygiene layer
- Valance sheet - optional, used to conceal the bed base and divan legs for a neater finish
All items are available in matching fabrics and colours across Belledorm's double range, making it straightforward to build a fully coordinated set.
Yes, UK double bed sheet dimensions are standardised: fitted sheets are 135cm x 190cm, flat sheets are 230cm x 275cm, and duvet covers are 200cm x 200cm. Belledorm's double range follows these standard UK dimensions throughout.
The one variable is fitted sheet depth, this is not standardised and varies by product and brand. Always check the box depth (30cm, 38cm, or 46cm) against your mattress measurement before purchasing. One common point of confusion is the duvet cover: a double duvet cover (200cm x 200cm) is square, not rectangular, this is correct and standard across the UK industry. If you are buying bedding as a gift or for a property you cannot measure, standard UK double dimensions apply to the overwhelming majority of double beds manufactured since 2000.
