King Duvet Covers FAQs

Fancy stretching out like royalty? Our king-size duvet covers are here to give you all the room you need for sprawling out whilst you snooze. Here’s everything you might want to know before diving under one.

What size is a king duvet cover?

A king duvet cover from Secret Linen Store measures a generous 225cm x 220cm. That’s plenty big enough to fit a UK king-size duvet and still leaves enough fabric for dramatic morning stretches.

Not quite sure which size your bed actually is? (You’re not alone.) Pop over to our guide for all the details.

Bed Linen Size Guide

Will my king duvet cover come with pillowcases?

Our duvet covers are sold separately, so you can build your perfect bedding set your way: mix, match, or go full coordination mode. But if it’s matching pillowcases you’re after, we’ve got loads of lovely options to choose from in each range.

You’ll find standard (50 x 75cm), large square (65 x 65cm), and super king pillowcases in many of our collections.

What materials do your king duvet covers come in?

We use only the finest cottons and linens in our bedding. Our king-size duvet covers come in:

100% Cotton – breathable, soft and brilliantly easy to care for.
100% Linen – gloriously lived-in, ultra-breathable and gets softer with every wash.
Cotton/Linen Blend – the best of both worlds (yes please).

If you're not sure which one’s for you, our Cotton vs Linen blog breaks it all down, fluff-free.

How do I wash and care for my king duvet cover?

To keep your cover lovely for longer, we recommend a cool wash (30–40°C) with a gentle detergent. Give it a good shake before hanging or laying flat to dry to keep creases at bay. And always wash similar colours together—no one likes a pink-tinged white sheet.

For the full lowdown, visit our guide below.

Bedding Care Guide

Where are our duvet covers made?

All of our duvet covers are lovingly made in Portugal and the UK by skilled makers we've worked with for years (decades, even!). We’re proud as punch of the quality, care, and craftsmanship sewn into every stitch.
