You’ll mostly pick the right duvet size based on the bed. For a cot measuring 60x120 cm, 100x135 cm usually fits best. For a toddler bed of 70x140 cm, 120x150 cm is often chosen, while 100x135 cm can still work for a compact bed. If your child sleeps in a single bed of 90x200 cm, 140x200 cm is the standard and 140x220 cm is handy for taller kids. That way the duvet won’t feel too big, too warm, or too short.

Which size suits which bed?
Duvet for cot 60x120 cm
For a cot, 100x135 cm is usually the best choice. A larger duvet might look roomy, but in a small bed it quickly means too much fabric. A more compact size looks tidier, feels calmer, and matches the bed’s dimensions better. Choose a duvet cover in exactly the same size as well.
Duvet for toddler bed 70x140 cm
With 70x140 cm you’ll often see two options: 100x135 cm and 120x150 cm. In practice, 120x150 cm is chosen most, because it gives your child a bit more room to move and they’re less likely to wriggle out from under the duvet. If you want a more compact fit, for example for a smaller toddler or a narrow bed frame, 100x135 cm can still work well. The main thing is that the duvet doesn’t hang heavily over the edges.
Duvet for kids’ or single bed 90x200 cm
Once your child sleeps in a 90x200 cm bed, you’ll want single duvet sizes. The standard is 140x200 cm. If your child is taller or you want extra length to tuck in at the foot, 140x220 cm is a logical step. It keeps up with growth spurts and you won’t have to replace it as quickly.

How to avoid a duvet that’s too big or too small
A well fitting duvet covers shoulders, tummy, and feet without lots of fabric hanging beside the bed. A duvet that’s too small leaves feet cold more quickly. One that’s too big can be awkward in a small kids’ bed and feel warmer than is comfortable. If you’re between sizes, choose a closer fit rather than extra large for smaller beds.
- Always look at the mattress size first, then the age.
- Check that the duvet sits neatly on the mattress and doesn’t fall far over the edges.
- Only move up to 140x200 cm when the bed is truly a single size.
- Make sure your child can move freely without getting tangled in excess fabric.
Always match duvet and cover sizes
A duvet cover should be the same size as the duvet. It not only looks better, it’s more practical too. In a cover that’s too big, the duvet can shift around, so you’ll be straightening it more often. In a cover that’s too small, you’ll pull the filling tight, which is less comfortable. Always match the measurements exactly, like 100x135 with 100x135 or 120x150 with 120x150. It keeps the bed neater and helps your child sleep more peacefully.
Helpful for parents: check the care too
Besides the right size, care matters. With kids you’ll want bedding fresh again quickly after a warm night or an accident. Always check the care label and choose a duvet that fits how often you want to wash. For busy families, a machine washable duvet can be extra handy, especially if you want to remake the bed fast.
