Choose a linen duvet cover by the dimensions of your duvet insert, not your mattress or the word Queen or King. Size labels vary by brand and country. Measure your insert, compare the product’s exact dimensions, then choose a listed size or request a custom quote.
Find a cover for your insert
- For 100% linen: shop French linen duvet covers and sets. Our French linen fabric is 165–175 GSM.
- For a bamboo-linen blend: view the White 70% Bamboo Rayon / 30% Linen Duvet Cover. This listing includes one cover; check the size selector for its dimensions.
- For a size not listed: send the insert width × length, preferred fabric and colour, quantity and destination before ordering.

Duvet sizes in cm: why country labels are not enough
These examples show how dimensions vary; they are not a universal size chart or a list of SCANDALINEN stock options. Always compare the actual insert with the selected product.
- Australia: an Australian King quilt cover may measure 245 × 210 cm. New Zealand labels can differ; Sheridan labels this dimension NZ Super King.
- United States: Queen dimensions vary by maker. Examples include 90 × 90 inches (228.6 × 228.6 cm) and Full/Queen covers at 90 × 96 inches (228.6 × 243.84 cm).
- United Kingdom: King inserts can be labelled 225 × 220 cm or 230 × 220 cm, depending on the maker. Read the actual measurements.
- European ranges: dimensions such as 200 × 200 cm and 240 × 220 cm are available, but there is no single size naming system covering every country and brand.
Examples can be checked in the Sheridan size guide, The Linen Company size chart, The Company Store Full/Queen listing, John Lewis King duvet listing, Cuddledown size guide and IKEA duvet-cover range.
How to measure before you order
- Lay the insert flat and smooth it gently without stretching it.
- Measure width and length from edge to edge and record the units.
- Compare your measurements with the cover’s listed dimensions and the insert maker’s guidance.
- If the fit is uncertain, send a photograph of the tape and ask us before buying. Do not automatically add a fixed allowance.

Check what the price includes
A duvet cover is the removable outer cover. It does not include a duvet insert unless the listing explicitly says so. Sets can include different combinations of sheets and pillowcases; check the exact contents and pillowcase dimensions before adding to your basket.
Using two separate duvets on one bed? Measure each insert and choose a cover for each, rather than buying one large cover based on the bed size.
Custom-size linen duvet covers
If your insert sits between listed sizes, ask about a made-to-measure cover. We will confirm feasibility, finished dimensions, available fabric and colour, price and timing. Oversized or unusual constructions need confirmation; we do not assume every size can be made without seams.
Our French linen fabric is 100% linen, 165–175 GSM, and OEKO-TEX STANDARD 100 certified. That certification statement applies to the French linen fabric, not automatically to bamboo-linen blends or fillings.

Before you place the order
- Check fastening details on the individual listing.
- Follow the product care instructions; natural linen may change dimensions with washing and drying.
- Allow approximately 3–4 weeks from ordering to arrival, including making and international shipping. Confirm custom requirements and deadlines with us.
- Read our return and exchange information and ask how it applies to your custom request.
