King Size Duvet covers

Collection: Buy King Size Duvet covers on Sale

A UK king size duvet cover measures 230cm x 220cm, built for a king bed (150cm x 200cm) with enough extra fabric to stop the duvet shifting around during the night. Weight and weave matter more than people expect: a lightweight percale weave feels crisp and breathable, which suits anyone who runs warm, while a denser sateen weave has a smoother, slightly heavier drape that some find more luxurious. Zip or button fastenings along the open edge are also worth checking, as zips tend to stay put better through repeated washing than poppers. Pairing a king duvet cover set with the right duvet and a set of pillowcases finishes the bed properly, particularly if you're moving from a smaller bed size and need to replace more than just the cover.

Will a double duvet fit inside a king size duvet cover?

No — a double duvet is too small for a king size cover and will leave loose fabric bunching at the corners, so it's worth checking your duvet's dimensions match the cover before buying. Shoppers also often ask whether king size bedding runs differently between brands, and it's a fair concern, as sizing can vary by a few centimetres depending on the manufacturer, which is why checking the exact measurements on each product page is worthwhile rather than assuming "king" means identical dimensions everywhere. If you're refreshing the whole bed, our bed sheets and mattress protectors & toppers are worth considering alongside your new king size duvet cover.
