A Bed Linen Size Guide

Bed Linen Size Chart UK

All measurements are in centimetres and reflect standard UK sizing used across bed linen. Always check your mattress label and measure if you are unsure.

If you’re building a complete bed linen set, matching sizes across bed sheets, duvet covers and pillowcases gives the cleanest finish. Our bedding collections are designed so each piece works together without second-guessing.

Why Bed Sheet Size Matters

The right size does three things: it keeps the bed feeling smooth, it prevents fitted corners from loosening in the night, and it helps the fabric wear evenly over time.

Common signs that the sizing is wrong:

• corners lifting on a fitted sheet
• excess fabric that creases and twists
• sheets that pull tight and feel restrictive
• constant re-tucking and re-adjusting

If you want a bed that looks neat with minimal effort, start by getting the sizing and depth right, then choose the fabric that suits how you sleep.

How To Measure Your Mattress

Measure the mattress with all layers in place, including any topper and protector you use every night.

• Width: side to side across the top surface
• Length: head to toe across the top surface
• Depth: top surface down to the bottom edge, including topper and protector

Depth is the detail most people miss. If you use a topper, measure again with it on. That combined height is the depth your fitted sheet needs to cover comfortably.

If your bed has a mattress topper or a thicker mattress than normal, our extra-deep fitted sheets are designed to sit securely without pulling tight at the edges. 

Fitted & Flat Bed Sheets

1. Fitted Bheets

Fitted sheets are the base layer that makes the whole bed feel correct. Elasticated corners hold the sheet neatly in place, so you wake up to a smooth surface rather than fabric that has shifted overnight. Our fitted sheets are made with extra-deep corners, designed to sit securely on modern mattresses and accommodate toppers without strain.

If you are choosing one sheet to start with, make it the fitted sheet. It does the heavy lifting for you.

2. Flat Sheets

Flat sheets add a refined layer between you and the duvet, helping the bed feel cooler, cleaner and more considered. They also create that classic foldback at the top of the bed, which makes everything look instantly more polished. If you enjoy a hotel-style finish, our flat sheets are designed to pair seamlessly with the rest of your bed linen, with generous proportions for an easy tuck and a clean drape.

Sheet Depth and Modern Mattresses

Many modern mattresses are deeper, and toppers can add even more height. herefore, choosing the right fitted sheet depth is what stops corners from lifting and fabric from straining.

If you have ever fought the corners while making the bed, this is the fix. Our fitted sheets are cut with extra depth so they sit properly on today’s mattresses.

Choosing the Right Feel

Sizing gets the fit right. Fabric gets the feeling right. Choose based on how you sleep and the finish you like on the bed.

• Crisp and cool cotton percale: fresh, breathable, and particularly satisfying if you run warm
• Soft and smooth cotton sateen: a silkier hand-feel and a more cocooning finish
• Relaxed linen: breathable with an effortless drape that softens beautifully over time

If you are refreshing the whole bed, choose your sheet first, then match the duvet cover and pillowcases to keep the finish consistent. Our collections are made to layer neatly, so the bed looks calm, polished and complete.

Pillowcase Sizes

Pillowcases do not need to be complicated. These are the most common UK sizes used across bed linen.

If you want the bed to feel calmer and more elevated, keep pillowcase sizing consistent across the front row, then add squares behind only if you genuinely use them.

Our pillowcases are designed to pair cleanly with our duvet covers and sheets, so the bed looks cohesive from every angle.
