As if bed sizes in the UK don’t cause enough confusion, duvet sizes get more complicated as duvet suppliers don’t all use exactly the same dimensions. So sometimes your duvet cover may not be an exact fit for your duvet even though they are given the same name. So it’s always worth checking the exact dimensions. However generally speaking although there is some tolerance in sizing, you should usually be okay if you get for instance a king size duvet cover for a kingsize duvet.
Of course you are not obliged to have the same size duvet as your mattress or bed. So, many people will have a super king size duvet on a king size bed and that will work fine! Here is our guide to UK duvet sizes followed by our UK duvet size chart:

A small single bed measures 75cm x 190cm. This is approximately equivalent to 2’6″ x 6’3″. This size is not really adequate for most adults and is more suitable for children and young teens.
Single duvet size (3′ wide)
