There is nothing worse than a duvet too big for the duvet cover that doesn't fit properly or a duvet cover that is oversized on the duvet. As with all bedding the best way is to give your duvet / duvet cover a quick measure to establish what you have and what you need. Below is a run down of duvets and sizes, it is best to buy your duvet / duvet cover the same size as even though they are described as the exact same measurement the covers are made to fit the duvets. The most common problem customers seem to have is using the duvet the wrong way on the larger sizes, the King, Super King and Emperor / Large Emperor where the width is wider than the length.
Standard UK Single Duvet - 54" x 78" (135cm x 200cm)
A UK Single duvet has never been the most generous size of duvet for the 3ft wide bed, but still very popular and used alot now on the smaller 2ft 6" wide beds. Sometimes manufacturers may describe a single duvet / duvet cover measurements as 135 x 198cm or 137 x 200cm but it is still a single duvet.
Long Single Duvet - 54" x 86" (135cm x 220cm)
Long Single beds are very popular and there is nothing worse than your toes sticking out the end of the duvet! We have a simple answer! A long single duvet.
Small Double Duvet - 67" x 86" (170cm x 220cm)
A small double duvet is 8" (20cm) longer than a standard single or double duvet, so great also for the longer 6ft 6" (200cm) beds. It is also 12" (30cm) wider than a Single duvet, but 12" (30cm) smaller in width than a Double duvet. When a single duvet is too small and a double duvet is too big, the small double duvet is the answer.
Standard UK Double Duvet - 78" x 78" (200cm x 200cm)
The original square duvet size and still as popular as ever for the 4ft 6" wide double bed. This size can be used on a small double 4ft wide bed if you don't mind it a little oversized.
UK King Size Duvet - 90" x 86" (230cm x 220cm)
A king size duvet is slightly wider than its length and often confused with a double duvet as it looks square. The King is most commonly used on a 5ft King bed, but we find customers quite often are using a king on a double bed.
UK Super King Size Duvet - 102" x 86" (260cm x 220cm)
Super King use to be a very specialist option, but is now a standard UK size and customers like to also use this more generous size on king size (5ft), Ikea King (5ft 3") and Small Super King (5ft 6") beds.
Emperor Size Duvet - 114" x 93" (290cm x 235cm)
This is now the recognized Emperor size and ideal for all Emperor bed sizes, Emperor Bed 6ft 6" x 6ft 6", Long Emperor Bed 6ft 6" x 7ft and Large Emperor 7ft x 7ft. Whether it is called Emperor or Large Emperor the duvet / duvet cover is the same size for the different size beds.
Caesar Size Duvet - 126" x 93" (320cm x 235cm)
Emperor Duvets are more than big enough for an 8ft Bed, but we now have the even wider Caesar duvets which are the same length as an Emperor, but even wider.
