Top tips for buying a duvet cover

  1. Duvet covers are always made to fit the same size duvet, so you don’t need to buy a bigger duvet cover size than your duvet.
  2. A double duvet is square so the cover will fit any way you pop the duvet in.
  3. The width of a king size duvet is slightly more than its length though, so make sure you have the duvet cover the right way round when you put it on.
  4. All scooms duvets and sheets come with handy feet labels so you easily know which way around your duvet, sheets and duvet covers go. Making your bed is suddenly a whole lot easier.
  5. International sizes use different terms for mattress and duvet sizes which can be confusing. For example, a UK King size is an international Queen size and a UK Super King is an international King size.
  6. Bedding terms can also differ internationally. For example in the US a duvet is sometimes referred to as a quilt, comforter or duvet insert. They're the same as a duvet.


Not sure which bed linen size - how to measure your mattress

  1. A retractable measuring tape is the easiest to use as you can fix it in place.
  2. Strip your mattress of all bed linen so you can measure the mattress exactly.
  3. Measure the width by placing the end of the measuring tape to the left side of the mattress, then extend the tape to the right edge.
  4. Measure the length by placing the end of the tape in the middle top of the mattress and stretch it to the middle bottom.
