Duvets & Duvet Cover Size Guide UK

Choosing the right duvet and duvet cover size is essential for a comfortable and aesthetically pleasing bedding setup. In the UK, duvet sizes are typically standardised. Still, it's always a good idea to double-check the specific measurements with the manufacturer or retailer, as there can be slight variations. 

What Is The Difference Between A Duvet And A Duvet Cover?


Duvet Cover

A duvet is a soft, fluffy, and usually quilted blanket filled with down, feathers, synthetic fibres, or other insulating materials. It's designed to keep you warm and comfortable while you sleep. 

Duvets are typically plain in design and come in various warmth levels to suit different seasons and preferences.

A duvet cover is a protective fabric shell that encases the duvet. It usually has a zippered or buttoned closure, allowing you to insert the duvet and remove it for washing. 

Duvet covers come in a wide range of colours, patterns, and designs, making them a versatile way to change the look of your bedding without replacing the duvet itself. They are also easier to clean than duvets, which can be cumbersome.

These are standard UK sizes, but variations can exist, especially with speciality duvets or custom-made bedding. When buying a duvet cover, it's essential to ensure that it matches the size of your duvet for a snug fit. Also, consider the depth of your mattress when choosing fitted sheets to complement your bedding. If you have a deep mattress, you may need deep-pocketed fitted sheets to ensure they stay in place.

Additionally, some duvet covers come with pillowcases included. Ensure that pillowcases are included with your duvet cover purchase or if you need to buy them separately.

How To Measure A Bed?

Bed sizes vary widely across different countries, each with its standards and terminology. If your bed or mattress wasn't explicitly made for the UK market, it's essential to take accurate measurements before purchasing new bedding. Using the wrong-sized bedding can lead to inconvenience and frustration, as what fits a King-size bed in one country may need to be corrected in another.

Width Measurement

  1. To measure the width, position the end of the measuring tape at the left side of the bed. 
  2. Extend the tape across until it reaches the right edge of the bed. 
  3. Make sure it's taut and straight for an accurate measurement.

Length Measurement

  1. Place the end of the tape at the middle top of the bed to measure the length. 
  2. Carefully extend the tape down to the middle bottom of the bed, keeping it straight and taut for an exact measurement.

Can I Use A Double Duvet On A King-Size Bed?

You can technically use a double duvet on a king-size bed, but the larger bed may need more coverage and warmth. A double duvet is designed for a smaller bed so that it might leave gaps and not properly drape over a king-size bed's sides. This can result in uneven coverage and might not warm both sleepers adequately.

Can I Use A Single Duvet On A Double Bed?

A single duvet on a double bed is possible but may not provide adequate coverage for both sleepers. A single duvet is designed for a smaller bed, so it will likely leave gaps and only cover part of the surface of a double bed. This can lead to discomfort and a lack of warmth, especially in colder months.


It's generally recommended to use the appropriately sized duvet for your bed to ensure comfort and warmth. Using a duvet that matches the bed size provides better coverage and insulation. Suppose you prefer the look of a single duvet on a double bed or a double duvet on a king-size bed for aesthetic reasons. You can do so in that case, but consider using additional blankets or throws to ensure everyone stays warm and comfortable.
