What size duvet for Ikea 140x200cm bed?

[mountainlover]

We're getting an Ikea double bed 140x200cm for our spare room and I've found some UK sized bed linen I like but don't know what size to get. I think this is bit bigger than a UK double but smaller than a King. Am I better off getting a UK double or king sized duvet? I don't want it too small, but equally one that is much too big is very annoying. Thanks

Get a king sized duvet. a standard double is too small in my experience.
