Size Guide for Duvet Covers
Duvet Cover Size Guide UK | Single, Double, King & Super King 9.5 Tog Duvets
Choosing the right duvet cover size is the difference between a beautifully dressed bed and a cover that bunches up, sits lopsided, or leaves your duvet slipping around inside. Our complete UK duvet cover size guide covers every standard size, single, double, king, and super king, with measurements in centimetres and inches, so you can order with confidence.
All our bamboo duvet covers are designed to pair perfectly with our 9.5 tog bamboo duvets. UK duvet covers are cut slightly larger than the duvet, giving you the drape over the sides of the bed and the neat, tucked finish that makes a bedroom look properly put together.

Each cover features a concealed full-width button fastening to keep your 9.5 tog bamboo duvet securely in place and prevent bunching or shifting overnight.
How to Choose the Right Duvet Cover Size
The right duvet cover size depends on your duvet size, how much drape you prefer, and whether you’d like to size up for a fuller finish. Here’s how to think about it.
Match Your Cover to Your Duvet
The most straightforward approach is to choose a cover that matches your duvet size. Our bamboo duvet covers are cut to pair perfectly with the corresponding UK duvet size, a king cover for a king duvet, a double cover for a double duvet, and so on.
Because UK duvet covers are slightly larger than the duvet itself, you’ll get a natural drape over the sides of the bed without the cover pulling tight.
Or Size Up for Extra Drape
Many sleepers prefer to size up by one, for example, using a king cover on a double duvet. This gives a more luxurious, hotel-style finish with a deeper drape over the sides and foot of the bed.
If you go up a size, your duvet will have a little more room inside the cover, so consider using duvet clips or corner ties to keep it from shifting.
Measure if You’re Unsure
If you’re buying a cover for an existing duvet, measure the duvet’s width and length while it’s flat and unfolded. UK duvet sizes are standardised, so your measurements should match one of the four sizes in our chart within a centimetre or two.
Single Duvet Cover (135 cm × 200 cm)
A single duvet cover is designed to fit a UK single duvet measuring 135 × 200 cm, providing a neat drape on a 90 × 190 cm single mattress. Ideal for:
- Children’s beds and cabin beds
- Single beds in guest rooms
- Bunk beds and student halls
- Day beds and box rooms
Pairs perfectly with our single 9.5 tog bamboo duvet and single fitted sheet.
Double Duvet Cover (200 cm × 200 cm)
A double duvet cover fits a standard UK double duvet measuring 200 × 200 cm, draping generously over a 135 × 190 cm double mattress. This size suits:
- Couples in smaller or mid-size bedrooms
- Single sleepers who prefer a more substantial drape
- Standard 4'6" double beds in main and guest rooms
The square shape also works widthways on a single bed for a fuller, more enveloping look.
King Duvet Cover (225 cm × 220 cm)
A king-size duvet cover is the most popular choice for UK couples and pairs with a king duvet measuring 230 × 220 cm. It drapes elegantly over a 150 × 200 cm king mattress with generous overhang on all sides. It’s ideal for:
- 5' king-size beds
- Couples who want individual coverage without fighting for the duvet
- Master bedrooms and main suites
Also works beautifully on a double bed if you’d prefer extra coverage and a fuller finish.
Super King Duvet Cover (260 cm × 220 cm)
A super king duvet cover pairs with a UK super king duvet measuring 260 × 220 cm, providing a deep, luxurious drape on a 180 × 200 cm super king mattress. Choose this size if you have:
- A 6' super king bed
- A larger master bedroom where you want a deep, full drape
- Children or pets who climb in and pull the covers
- A preference for an enveloping, hotel-style finish
Also a popular choice on a king bed for an especially generous overhang on every side.
How to Measure Your Duvet for the Right Cover Size
Not sure which cover size you need? Here’s how to work it out:
Strip Your Duvet
Remove your existing duvet cover so you can measure the bare duvet.
Measure the Width and Length
Lay the duvet flat and use a tape measure to record the width and length in centimetres.
Match It to the Chart
Compare your measurements to our size chart. UK duvet sizes are standardised, so you should land within a centimetre or two of one of the four sizes listed. Choose the matching cover, or size up for extra drape.
Frequently Asked Questions
What are the UK duvet cover sizes in cm?
Standard UK duvet cover sizes are: Single (135 × 200 cm), Double (200 × 200 cm), King (225 × 220 cm), and Super King (260 × 220 cm).
What size duvet cover do I need for a 9.5 tog king duvet?
A king duvet cover measuring 225 × 220 cm pairs perfectly with our 9.5 tog king bamboo duvet (230 × 220 cm). The cover is generously cut to allow natural drape without pulling tight.
Can I use a double duvet cover on a single bed?
Yes. Using a double cover on a single bed is a popular choice for extra drape and a more luxurious, oversized finish. Just note that your duvet will have more room inside the cover, so corner ties or clips can help keep it in place.
Can I use a king duvet cover on a double bed?
Yes, and it’s a popular styling choice. A king cover on a double bed creates a generous, enveloping drape and a high-end look. Use duvet clips at the corners to keep the duvet from shifting inside the larger cover.
Are your duvet covers fully fastened?
Yes. Every bamboo duvet cover in our range features a concealed button fastening that runs the full width of the opening, keeping your 9.5 tog bamboo duvet securely in place through the night.
Will your duvet covers fit other tog weights?
Yes. While our covers are designed to pair with our 9.5 tog bamboo duvets, they will fit any duvet of the same size, regardless of tog weight. A higher-tog duvet will be slightly thicker inside the cover; a lower-tog duvet will sit a little flatter.
Is a UK king duvet cover the same as a US king?
No. A UK king duvet cover (225 × 220 cm) is similar in footprint to a US queen, while a UK super king (260 × 220 cm) is closer to a US king. Always check exact measurements rather than relying on size names alone.
Will a UK duvet cover fit a European duvet?
Not always. European duvet sizes, including many IKEA models, often differ from UK sizes. Always match your duvet cover to the duvet’s actual measurements, not just the size name.
What’s the difference between a king and super king duvet cover?
A king duvet cover measures 225 × 220 cm and pairs with a 5' king duvet. A super king cover is wider at 260 × 220 cm and pairs with a 6' super king duvet, giving couples significantly more width and a deeper side drape.
How do I stop my duvet bunching inside the cover?
Our bamboo duvet covers feature a full-width button fastening at the opening. For additional security, use duvet clips or corner ties to anchor the duvet’s corners to the cover’s internal corners. This prevents shifting and bunching overnight.
