Mattresses vary in depth from 6cm to over 30cm and sometimes it's not very clear what the depth is in the maker's specifications. Here at scooms we've made our sheets deep fitting - 40cm / 15.7" - to make sure that they will fit almost every mattress and most importantly so that they are easy to put onto the bed!
|Duvet size||Mattress size|
|Single||135 x 200cm (4ft 5" x 6ft 7")||90 x 190cm|
|Double||200 x 200cm (6ft 7" x 6ft 7")||135 x 190cm|
|King||225 x 220cm (7ft 4" x 7ft 3")||150 x 200cm|
|Super King||260 x 220cm (8ft 6" x 7ft 3")||180 x 200cm|
King size duvet measurements
The King size duvet is fast becoming the most popular duvet size in the UK. A King size duvet measures 225 x 220 cm or 7ft 4" x 7ft 3". As the width of a King size duvet is slightly more than its length, when you are putting on your King size duvet cover double check that you have the duvet the right way round!
Should your duvet be bigger than your bed?
You may want to choose a duvet that is one size larger than your actual bed size if:
- You share a bed or just like more duvet to drape over you - you don't want your other half to roll over and take all the duvet!
- You like the way it looks - a larger size duvet can look more attractive as it hangs pleasingly over the edge of the bed.
- You are particularly tall - if your feet reach the end of your bed choose a duvet that is 30 cm longer than you are. You don’t want your toes or shoulders getting chilly during the night!
Duvet cover sizes
Duvet covers are made to fit the same size duvet. So you should always buy a duvet and duvet cover that is the same size. Even though they may be described in exactly the same measurements there is no need to 'go large'! You'll just end up with lots of extra duvet cover material and a duvet that moves around. Not very cosy!
How to measure a bed
Bed sizes vary around the world, with different countries using their own size standards and terminology. So If your bed or mattress wasn't made for the UK market, make sure you measure before buying new bedding. The likelihood is that if you buy King size fitted sheets in one country, they won't be quite the right size in another country which could be rather frustrating!

Measure your bed:
- First, take off all the bedding so that you can measure the bed exactly from the edges.
- Use a retractable measuring tape which you can lock into place. If it proves tricky, get a friend to help.
- Don’t forget to have your phone or a pen and paper handy so you can record the measurements.
- To measure the width: Place the end of the measuring tape at the left side of the bed, then extend tape out until it reaches the right edge of the bed.
- To measure the length: Place the end of the tape at the middle top of the bed, then pull out the tape to the middle bottom of the bed.
US v UK bedding sizes
The standard sizes for American beds are Twin, Full, Queen, and King, in ascending order, compared to Single, Double, King and Super King in the UK. Single bed and Double bed are understood and used in the US, but they are not exact bed sizes there.
European v UK bedding sizes
European bed and mattress sizes are often called Euro sizes. The main sizes are Single, Double and King. Each size is a little larger than the UK equivalent. They are sold by European manufacturers like Ikea.
