A Complete Guide to UK Bedding Sizes

How do I know my bed sheet size?

The best way to make sure your bedding and bed sheets fit your bed is to measure your mattress. Most mattresses in the UK will come in four standard sizes, as listed below. If your mattress is non-standard, then size up to the next largest bedding size. For example, if your single bed is wider than a standard UK single bed (such as a three quarter bed), then go for a double bedding set. For some, it’s a matter of personal preference: if you are a duvet-hogger you might want a king-size bedding bundle for that extra coverage. 

Common UK bed sizes:

• Single beds: in the UK, a standard single bed measures 90 x 190cm. Used for people to sleep in alone, these beds are great for smaller rooms where more space is needed and are commonly used for children’s rooms and bunk beds. 
• Double beds: a standard double bed is 135 x 190cm and this is the most popular bed size in the UK. 
• King beds: for those who want that extra bit of room or who might be a bit taller and need more length, the king-size bed measures 150 x 200cm. 
• Super king beds: for ultimate star-fishing, this bed is 180 x 200cm and is a great size for those with room to spare in the bedroom or who simply like to stretch out at night. 
• In case you were wondering, a Queen-sized bed (most commonly described as such in the US) is the equivalent to a UK king bed. 

How do I know what sheets will fit my existing duvet?

Most duvets will show their size on the care label, so check that first. If not, simply measure your duvet against the sizes in our table below and choose the right duvet cover for you. 

What do I need to furnish my bed?

In general, in the UK, we have moved away from the more traditional bedding of sheets, blankets and eiderdowns and most households now opt for duvets and duvet covers. For each bed, we generally advise the following: 

• One fitted sheet, to ensure it never slips off or bunches up in the night. Our fitted sheets are made with deep corners, to fit even the tallest mattresses. 
• One flat sheet, great for optional lighter coverage in the warmer months. 
• 2-4 pillowcases: be sure to check whether your pillows are standard, square or king-sized, based on the measurements in the table below. 
• One duvet cover - at Piglet in Bed, we love to mix and match our colourways from our full range of linen bedding.
