Duvet & Mattress Sizes for single, double, king-size, super king and emperor beds

When buying a duvet it is important to know what size you want. All of our duvets conform to the standard UK sizes although bespoke size duvets can be ordered on request.

If you already have duvet covers you probably want to buy a duvet that fits them. If you're unsure of the size you need then measure your existing duvets (or duvet covers) and compare to the table below.

Duvet Sizes	Metric	Imperial
Single Duvet	135x200cm	approx. 4ft 5” x 6ft 7”
Double Duvet	200x200cm	approx. 6ft 7” x 6ft 7”
King Size Duvet	225x220cm	approx. 7ft 4" x 7ft 3"
Super King Size Duvet	260x220cm	approx. 8ft 6" x 7ft 3"
Emperor size Duvet	290x235cm	approx. 9ft 6" x 7ft 8"

If you have no duvets or duvet covers you can identify the size you need by measuring the size of your mattress and comparing the dimensions to the table below. However, we suggest you consider buying one size up for a bit of extra comfort and to avoid the usual tug-of-war over the duvet in winter months.

Mattress Sizes	Metric	Imperial
Single mattress	90x190cm	approx. 3ft x 6ft 3"
Double mattress	135x190cm	approx. 4ft 6" x 6ft 3"
King size mattress	150x200cm	approx. 5ft x 6ft 6"
Super King size mattress	180x200cm	approx. 6ft x 6ft 6"
Emperor size mattress	200x200cm	approx. 6ft 6" x 6ft 6"
