Choose a duvet cover by the width and length of your duvet insert, not just the size of your mattress. The cover is a removable fabric shell; it does not include the filling. For winter, choose the insert for the warmth you need, then find a cover that fits it.
How to measure for a duvet cover
Start with the dimensions on your insert’s label. If the label is missing, lay the insert flat and measure its width and length without stretching it. Compare both numbers with the cover’s listed dimensions, using the same units.
Do not assume that every Queen or King is the same size. Measurements vary between brands and countries. An Australian Queen doona may need a different cover from a US Queen insert.
Want more overhang at the sides of the bed? Choose a larger insert and a cover that matches that insert. Buying a larger cover for the same smaller insert can leave empty fabric around the edges; it does not add filled coverage.
If none of the listed dimensions match, send us your insert measurements for a custom quote. Include the units and the colour you want. We will confirm the cover dimensions before you order.
What comes with the cover?
- A duvet cover on its own: one fabric cover, without pillowcases, sheets or inserts.
- A duvet cover set: one cover and two pillowcases, without a sheet or inserts.
- A four-piece bedding set: one cover, two pillowcases and your choice of a flat or fitted sheet. Inserts are not included.
Check the pillowcase dimensions as well as the cover dimensions when choosing a set. Pillows shown in a styled photograph may not all be included.
Choosing an insert for winter
The cover changes the fabric you feel against your skin, but it cannot make a light summer insert perform like a warmer one. Check the insert maker’s warmth rating and guidance for your bedroom temperature. Consider whether you sleep hot or cold and whether the room is heated.
If you want an extra removable layer, use a blanket over the bedding. A mattress topper goes beneath you and is not a substitute for a duvet insert.
Choosing the linen
SCANDALINEN’s French linen covers are made to order in Hanoi. Plain-dyed linen is 165 GSM; yarn-dyed linen is 175 GSM. Fabric weight describes the cover fabric, not the warmth rating of the filled duvet. Check each product’s construction and closure details before ordering.
For a closer look at fabric weight, read our linen GSM guide.
Washing and the first fitting
Follow the care label supplied with your cover, including its drying instructions. Our stonewashed French linen may shrink a further 2–5%; wash before the first fitting. If your insert needs a particularly close fit, ask us to confirm the sizing allowance before ordering.
Common questions
Should I buy a duvet cover one size larger?
Only if its actual measurements match the insert you plan to use. To get more filled coverage, choose a larger insert and its matching cover together.
Do I need a flat sheet as well?
No. It is a preference. You can use a duvet cover without a flat sheet, or add one as a separate washable layer between you and the duvet.
Does a linen cover guarantee a warm winter bed?
No single cover guarantees that. The insert, other bedding layers, room temperature and your own comfort preferences all matter.
Can I order a cover for an unusual insert?
Yes. Send the insert’s width and length, the units and your preferred colour through our custom order enquiry. We will confirm the details and price before payment.
