UK duvet size chart (cm and inches)
| Bed | Duvet (cm) | Duvet (inches) |
|---|---|---|
| Single (90 × 190cm bed) | 135 × 200 | 53" × 79" |
| Small Double (120 × 190cm bed) | 200 × 200 | 79" × 79" |
| Double (135 × 190cm bed) | 200 × 200 | 79" × 79" |
| King (150 × 200cm bed) | 225 × 220 | 89" × 87" |
| Super King (180 × 200cm bed) | 260 × 220 | 102" × 87" |
This chart covers standard UK duvet sizes and measurements. A double duvet measures 200 × 200cm (79 × 79 inches) — the same duvet dimensions fit both small double (120cm) and standard double (135cm) beds. A king size duvet measures 225 × 220cm, and a super king duvet is 260 × 220cm. If you're checking duvet sizes in cm against an existing duvet, measure it flat, seam to seam.
Duvet cover sizes UK — what size cover fits each duvet?
Duvet cover sizes match duvet sizes exactly — a double duvet takes a double duvet cover (200 × 200cm), a king size duvet takes a king size duvet cover (225 × 220cm), and a super king duvet cover measures 260 × 220cm. Always buy the cover to fit your duvet, not your mattress — that's the most common duvet cover sizing mistake.
| Duvet | Duvet cover size (cm) | Cover size (inches) |
|---|---|---|
| Single | 135 × 200 (some brands 140 × 200) | 53" × 79" |
| Small Double / Double | 200 × 200 | 79" × 79" |
| King | 225 × 220 | 89" × 87" |
| Super King | 260 × 220 | 102" × 87" |
A small double duvet cover is the same size as a double duvet cover — 200 × 200cm — because both bed sizes share the same duvet. If your cover feels loose with empty corners, it's a size too big for the duvet inside it; if the duvet bunches, the cover is too small.
UK vs US and European duvet sizes (queen, comforter and Euro sizes explained)
If you've seen 'queen size duvet' or 'comforter' while shopping, those are American terms. The US queen (better matched by a UK king size duvet) and US king don't line up with UK names — a queen size duvet in inches is roughly 88 × 90", closest to our 225 × 220cm UK king. 'Comforter' is simply the American word for a duvet, so double comforter dimensions in the US won't match a UK double duvet. European duvet sizes differ again: a Euro double duvet is typically 200 × 200cm like ours, but Euro single duvets run 140 × 200cm and IKEA beds follow European mattress sizes — so always compare centimetres, not names.
| If you see... | It roughly means (UK) | Size |
|---|---|---|
| Queen duvet / comforter (US) | Closest to UK King | ~225 × 220cm |
| US King comforter | Larger than UK Super King | ~265 × 230cm |
| Euro single duvet | Between UK single sizes | 140 × 200cm |
| Emperor duvet | Larger than Super King | 290 × 235cm |
Extra long, emperor and non-standard duvet sizes
An extra long single duvet (typically 135 × 220cm) suits taller sleepers on standard single beds. Emperor duvet size is 290 × 235cm for emperor beds. 200 x 200 duvet, 220 x 240 and 240 x 220 duvet cover sizes are European cuts — check which dimension is the width before ordering, as continental duvets are sometimes longer than they are wide.
Should I size my duvet up?
Size up one bed size if you share a bed (it stops duvet-hogging), have a deep mattress, or want the draped hotel look — a King duvet on a Double bed is a popular stylist's trick. Keep the matching size for children's rooms and where the bed sits against a wall.
Popular combinations: a king duvet on a double bed gives a generous hotel-style drape and stops duvet-hogging between partners. A super king duvet on a king size bed does the same at the larger scale. Going the other way — a double duvet on a single bed — works well for single sleepers who like extra wrap-around coverage. Just remember the cover must match the duvet size, not the bed.
Which tog do I need?
| Season / bedroom | Tog | Best for |
|---|---|---|
| Summer / hot sleepers | 4.5 | Warm bedrooms, summer months |
| Spring & autumn | 10.5 | Most UK bedrooms most of the year |
| Winter | 13.5 | Unheated bedrooms, cold sleepers |
| Deep winter | 15 | Very cold rooms, no overnight heating |

Does the duvet cover match the duvet or the bed?
The duvet — always. A common mistake is buying the cover to match the mattress size.
Duvet size FAQs
What size is a double duvet?
A double duvet is 200 × 200cm (79 × 79 inches) in the UK. The same size fits both small double (4ft) and standard double (4ft 6) beds, and takes a 200 × 200cm double duvet cover.
What size is a king size duvet?
A UK king size duvet measures 225 × 220cm (89 × 87 inches). Note it's slightly wider than it is long — check the label or the feet tag when putting on the cover.
What size is a super king duvet?
A super king duvet is 260 × 220cm (102 × 87 inches), fitting a 180 × 200cm super king bed with a full drape on both sides.
What size is a single duvet?
A standard single duvet is 135 × 200cm (53 × 79 inches). Some brands cut singles at 140 × 200cm, so check the label if you're replacing a cover.
What size is a small double duvet?
Small double beds (120 × 190cm) use the standard double duvet — 200 × 200cm. There is no separate small double duvet size; the double gives the right overhang.
Is a UK king size duvet the same as a US king?
No. A UK king duvet (225 × 220cm) is closest to a US queen. A genuine US king comforter is larger than a UK super king. Always compare centimetre measurements rather than size names.
What is a queen size duvet in the UK?
'Queen' is a US bed size — the UK equivalent is a king. If a pattern or listing asks for a queen size duvet, a UK king size duvet (225 × 220cm) is the closest match.
What size duvet for a double bed?
A 200 × 200cm double duvet. If you share the bed or want a fuller drape, size up to a king duvet (225 × 220cm) — just pair it with a king size cover.
What's the difference between a duvet and a quilt?
In the UK the words are used interchangeably — a double quilt size is the same as a double duvet size (200 × 200cm). Technically a quilt is a stitched-through layer and a duvet has a removable cover, but sizing is identical.
What size duvet for a cot bed?
Cot bed duvets are 120 × 150cm, but babies under 12 months should not use a duvet at all due to overheating and safety risk. For toddlers over one year, choose a low tog (4 tog or under).
How do I measure my duvet?
Lay it flat and measure seam to seam — width first, then length. Compare against the chart above. If it's between sizes, it's likely a European cut or has shrunk slightly with washing.
