Bed linen is not just the outer layer of bedding – it is a key component of maximising the potential of the entire bed.
Bed linen – referring to bedsheets, pillowcases, duvet covers, and other decorative elements– is a perfect showcase of style for your bedroom. Coming in countless patterns, styles, or customisation options, bed linen can tie the aesthetic of the entire bedroom together as the room’s central component.
That’s not all – as bed linen can vary in texture, fabric, and other materials, they significantly impact how sleepers benefit from the warmth and softness of inner bedding, and can affect the overall quality of sleep.
With so many different sizes and variations of bed linen available, it can be quite a challenge to find the correct size of bed linen. This guide will help you make an informed decision about the various size names and what they mean.
It’s not necessary to have the exact same size duvet cover as your mattress - for example, you could opt for a king-size duvet for a double mattress, which would allow for extra overlap on the sides of the bed. It is all down to personal preference when it comes to choosing a cover.
There are four standard UK bed sizes, as listed below:
Size Name |
Dimensions in Centimetres (cm) |
Single |
90 x 190 |
Double |
135 x 190 |
King |
150 x 200 |
Super King |
180 x 200 |
These sizes are based on UK averages and may be subject to variation, depending on the brand. The chart above uses standard sizing, and variations should remain close to the listed sizing.
Choosing the right bed linen size is all about the mattress size, so if you are unsure of the sizing, you should measure your mattress with a tape by width, length, and depth. The majority of mattresses will fit into one of the size categories mentioned in the chart above. Some mattresses will have the size mentioned on their care label.
Most sleepers opt for a fitted sheet over their mattress, as they tend not to become loose and tangled in other bedding, so checking the depth of a fitted sheet against the depth measurement of your mattress is essential in finding a good fit.
The chart below is based on UK standard sizing, although may vary slightly by brand.

To find the perfect fit, measure your mattress by width, length, and depth using a tape measure. Compare these measurements to the size chart provided (e.g., Single, Double, King, or Super-King). If your mattress depth varies from standard sizes, ensure the fitted sheet accommodates it to prevent slipping or bunching.
Yes! It’s common to use a larger duvet cover, like a king-size duvet on a double mattress, for added overlap and a more luxurious look. This is purely a personal preference and can enhance both style and comfort.
Fitted sheets are designed to stay snug over the mattress, so matching the depth is crucial to avoid loose or ill-fitting bedding. Standard mattress depths are usually around 30cm, but variations exist. Always check your mattress depth and compare it to the sheet’s specifications before purchasing.
