At Undercover, we offer you many different sizes: from all common Swiss standards to German and IKEA sizes in selected designs.
Here are our top tips for ordering the correct size:
Measure your bedding
If you are not sure which size you need, take a moment to measure your bedding first. Even if you know that your mattress, for example, measures 160x200 cm, your duvet cover might be a completely different size.
By the way: don't worry if your measurement differs by a few centimeters from the published size; you won't really notice the difference in bed. Our bedding is hand-sewn and can vary by 1-2 cm anyway. In addition, bedding can typically shrink by another 1-2 cm after washing.
Filter by size
In our shop, you'll find a size filter. Once you know your size, you can easily check which designs are available here.
