Duvet & Duvet-Cover Sizes by Market: A Wholesale Export Guide (US/UK/EU/AU/Gulf)

There is no single global duvet size. A duvet or cover is named after the bed it dresses, not its own dimensions, and the same name means different centimeters in each market — a US 'King' comforter is about 259 × 224 cm, while a UK 'King' duvet is roughly 225–230 × 220 cm. On top of that, continental Europe often dresses a double bed with two single duvets, not one. So the rule for export is simple: cut to the destination market's exact centimeters, never to the name.

Duvet, insert and cover — the terms

The insert (or comforter) is the filled inner that gives warmth; the cover (also quilt cover in Australia or doona cover) is the washable outer envelope that slips over it. A duvet is always larger than its mattress because it has to drape on three sides — roughly 25–40 cm wider and 15–20 cm longer than the mattress.

Duvet & cover sizes by market

Watch the name-collision traps: a US Queen (224 × 234) is bigger than a UK King (about 225 × 220); a UK Double (200 × 200) has no US size of the same name; and the Gulf uses a square 200 × 200 cm Super King mattress that needs oversized covers.

The European two-single-duvets convention

This one catches exporters out. Across Scandinavia, Germany, Austria and Switzerland, a couple's double bed is dressed with two separate single duvets (typically 135 × 200 or 140 × 200 cm each; Nordic 150 × 210), not one shared double. The two duvets overlap only a few centimeters in the middle — that gap is the correct look. So when a German buyer orders duvets 'for double beds,' they usually want two single covers or inserts per bed. Confirm the quantity logic in writing or you will ship the wrong SKU.

Insert vs cover fit, and closures

Cut the cover the same nominal size as the insert, or up to about 2–5 cm smaller, so it gently compresses the insert for a full, lofty look and stops it shifting. A cover cut larger lets the fill slide and bunch in the corners and looks empty. Specify the closure explicitly — buttons (UK/EU classic), zip (US and hotel), ties or an envelope flap (budget) — and include internal corner ties (4 or 8) with matching loops on the insert so the fill cannot slump.

How to spec a duvet or cover order

Never cut a duvet to a name. A 'King' is four different sizes in four markets, and a European 'double' is often two single duvets — cut to the destination's exact centimeters.

Frequently asked questions

A US and a UK client both ordered 'King' covers — can I run one cut?

No. A US King insert or cover is about 259 × 224 cm, while a UK King duvet is roughly 225–230 × 220 cm — different width and far wider in the US. Same name, different centimeters, so cut each to its destination market.

My German buyer ordered duvets 'for double beds' — one big duvet or two?

Almost certainly two single duvets per bed (135 × 200 or 140 × 200 cm each), the continental two-duvet convention. Confirm in writing before cutting, because shipping one double is a common and costly error.

Should the cover be the same size as the insert or different?

The same nominal size, or cut the cover about 2–5 cm smaller so it compresses the insert for a full, lofty look and holds it in place. A cover cut larger lets the fill bunch in the corners and looks empty.

Which closure and anti-shift feature should I quote as standard?

Match the market — buttons for UK/EU, zip for US and hotel, envelope for budget — and include internal corner ties (4 or 8) with matching loops on the insert so the fill cannot slump. State the closure explicitly on the spec sheet.

How do I stop finished goods measuring undersize after the first wash?

Add a shrinkage allowance (cut oversize about 2–4% for cotton, more for high-shrink weaves), pre-shrink or Sanforize where possible, and approve a washed, measured sample against spec before bulk. Cotton shrinks most in length.
