What bed linen size do I need? The ultimate guide.

Buying the correct bedding size can be surprisingly tricky. You think you have a king bed and then it turns out your duvet cover is actually a double. Been there? Cut yourself some slack because the bedding industry hasn’t made this easy with lots of different sizes available. Not to mention IKEA who have their own size standard and if you’ve lived abroad you’ll know that every country has its own bed linen sizes, too.

We offer a number of sizes, including standard UK, some USA sizes and IKEA sizes in certain styles. Here are our top tips to make sure you order the correct size:

Measure your bedding

If you’re unsure, grab a tape measure and check your mattress, duvet and pillow sizes. Some of our customers own a mattress size (such as a double) paired with a different duvet size (such as a king).

Don’t lose sleep if your bedding measures a couple of centimeters off from a “standard” size: you won’t notice the difference once the bed linen are on the bed and the fabric can shrink 1-2cm after washing anyway. Just buy the size closest to what you measured.

Use our size filters

On our shopping pages you’ll find a handy size filter. Once you know the size you need, just filter away and you’ll see what we’ve got in your size.
