Silk pillowcase size chart
Pillowcase and size Suitable pillow insert sizes Silk weight Closure
UK Standard / US Queen
50 × 75 cm (20 × 30 in)
50 × 75 cm or 20 × 30 in (approx. 51 × 76 cm) 25 momme Envelope closure
UK Super King / US King
50 × 90 cm (20 × 36 in)
50 × 90 cm or 20 × 36 in (approx. 51 × 91 cm) 25 momme Envelope closure

Both Classic and Oxford silk pillowcases use a discreet envelope closure, without a zip. Their 25 momme weight refers to the silk fabric, not the thickness of the pillow insert. Choose your pillowcase by measuring the pillow itself rather than relying solely on your mattress size.

Choosing the right silk pillowcase is simple, whether your pillows are sized in centimetres or inches. Our two pillowcase sizes are designed to accommodate both familiar UK dimensions and their slightly larger US equivalents.

UK Standard / US Queen – 50 × 75 cm (approximately 20 × 30 in)

Our UK Standard silk pillowcase fits both 50 × 75 cm pillows and standard US Queen pillows measuring 20 × 30 inches (approximately 51 × 76 cm). Both sizes fit beautifully, so there's no need to worry about the small difference between metric and imperial measurements. This is our everyday pillowcase size, suited to most UK single, double and king beds.

Two standard 75 cm pillowcases placed side by side span the width of a UK king-sized bed (150 cm).

UK Super King / US King – 50 × 90 cm (approximately 20 × 36 in)

Our UK Super King silk pillowcase accommodates both 50 × 90 cm pillows and US King pillows measuring 20 × 36 inches (approximately 51 × 91 cm). Again, both pillow insert sizes work equally well with the same pillowcase. This longer format is ideal for UK super king and emperor beds.

Two 90 cm pillowcases placed side by side span the width of a UK super king-sized bed (180 cm).

In short: You can choose by the size printed on your pillow, whether that's 50 × 75 cm or 20 × 30 in, 50 × 90 cm or 20 × 36 in. The matching Mayfairsilk pillowcase is designed to suit either measurement.

Cushion cover and Euro sham size chart

For a beautifully plump cushion, we generally recommend an insert that is slightly larger than the silk cover. The best fit depends on the filling: soft, compressible inserts can be up to 5 cm larger in width and height, while firmer, densely filled inserts may need a closer fit.

Cushion cover Cover size Recommended insert size Closure style
Square 40 × 40 cm (16 × 16 in) 43 × 43 to 45 × 45 cm Concealed zip
Large Square 50 × 50 cm (20 × 20 in) 53 × 53 to 55 × 55 cm Concealed zip
Euro Sham | Extra Large Square 65 × 65 cm (26 × 26 in) 68 × 68 to 70 × 70 cm Concealed zip
Boudoir | Rectangle 30 × 50 cm (12 × 20 in) 30 × 50 to 32 × 52 cm Concealed zip

Choosing the right cushion filling

Silk has a naturally smooth surface, so the quality of the insert makes a visible difference. For a soft, luxurious finish, our preference is for premium down or a well-made silk-filled insert. Fine kapok is another natural, plant-based option where available. Choose an insert with evenly distributed filling and enough loft to reach the corners without stretching the seams.

We generally avoid coarse, feather-heavy inserts beneath silk: quills and uneven filling can create little bumps that become more noticeable in close-up photography. If a particularly smooth, structured silhouette is the priority, a high-quality microfibre insert can also work well, although it is a synthetic alternative.

Styling tip: Start with an insert around 3 cm larger in each overall dimension, then go up to 5 cm larger for a softer, more compressible filling and a fuller look. For our 65 × 65 cm Euro sham, for example, a 68 × 68 cm or 70 × 70 cm insert can create a beautifully plump finish. Our Euro shams and decorative cushion covers currently feature a concealed zip closure for a neat, tailored appearance.

The Mayfairsilk difference

More to silk than meets the eye

Momme (pronounced ‘mom-ee’) measures the weight of silk fabric. A higher number means more silk by weight in the same area of fabric. It is one part of the picture, alongside the fibre grade, weave and finishing.

Every Mayfairsilk pillowcase is made from 25 momme, Grade 6A Mulberry silk. Substantial silk, a beautifully smooth feel and our signature soft matte sheen; made for your nightly ritual.

Our signature finish

A softer sheen. A modern kind of silk.

Silk needn’t have a high-gloss look. Our weave and finishing give Mayfairsilk its distinctive matte appearance, with a subtle lustre that catches the light.

Rich colour, a smooth hand feel and a relaxed, contemporary look; silk that feels as beautiful as it looks in your bedroom.

Customer photo review of Brilliant White Pure Silk Pillowcase

I received my beautiful white with charcoal edging pillow cases yesterday and I am so in love! They are simply stunning. I have had silk pillow cases before from various companies but these from Mayfairsilk are on another level of quality. They were packed impeccably so I knew straight away I had chosen well. I have curly hair & Rosacea so silk is perfect to lay on. I now want to add the sheets & duvet cover now as I can only imagine what it would be like to actually sleep in the whole set! Amazing - thank you.

Sleeping Like A Princess! Thankyou MayfairSilk for my luxury pillow slips. We are sleeping on these beautiful pieces of silk tapestry each night, which has been dreamy as well as gentle and comfortable on the face and feels soft and silky. We are sleeping more sound as well which if a priority as busy business people who travel often. Which is one of the reasons for purchasing this delight so I can take it traveling with me for a bit of “Home Sweet Home” whilst away. #Treated like a Princess

Arrived promptly and well packaged. The pillowcases are an excellent quality and wonderful to sleep on.

Brilliant White Pure Silk Pillowcase

Quality silk, beautiful white color, and exceptionally silky feel. Could not be happier, but wish I'd found Mayfair silk sooner.

Brilliant White Pure Silk Pillowcase

The pillow slips were a gift for a friend who is undergoing radiotherapy on her head. She gave me her feedback today and is delighted and loves them. She said they enable her to move her head around with ease and are very comfortable. I wanted to leave this review so other people going through treatment will know these beautiful silk pillow slips are worth the outlay.

Brilliant White Pure Silk Pillowcase

I had tried many silk pillowcases but this one is in a league of its own! I pls do buy another one as I never want to be without this now! My hair is so soft in the morning. I sleep so much better - the quality is phenomenal.

Haven't ordered silk pillowcase from this firm previously but am thrilled by my purchase. Great quality and delivery, customer services have been very helpful too

Lovely pillowcase, I have felt it but not yet slept with it on my pillow. Looking forward to using it though.

Brilliant White Pure Silk Pillowcase

Very pleased with this pillow case. Excellent quality. I have bought several over the years from different sources and would definitely recommend this one. Postage was good and comes in a beautiful box, ideal for a present for someone etc.

Brilliant White Pure Silk Pillowcase

Easy to order with lots of information on site. Arrived well packaged and very quickly which was a pleasant surprise. Product itself is beautiful and lovely against the skin, I even purchased the laundry bag for added protection. Highly recommend

Brilliant White Pure Silk Pillowcase

I purchased this silk pillowcase to replace an older one I'd bought elsewhere. I wanted a white one to match my bedding, is a brilliant white and I couldn't be happier with it! It feels so soft on my face and already I feel it's making my hair smoother on a morning. It feels far superior to the one I'd bought from "This Is Silk" a couple of years ago. Yes, it was quite expensive but I feel I got a great discount so I'm more than happy with my purchase! I would recommend this to anyone who wants a bit of luxury in their lives for an affordable price. Go on you are worth it!

Brilliant White Pure Silk Pillowcase

Bought four as Xmas presents and everyone was delighted The quality and colour were exceptional Will be buying some for myself in the new year

Brilliant White Pure Silk Pillowcase

Beautifully soft and silky pillowcase and my hair is not dry and frizzy in the morning anymore. Washed it in the mesh bag with Silk laundry detergent in 30 degrees Delicates cycle in the washing machine, no spin then blotted with a clean white towel and line dried - turned out perfect with minimal creasing. Also bought 2 silk teal pillowcases for my daughter and she was delighted.

Brilliant White Pure Silk Pillowcase

Absolutely beautiful pillowcases. I’ve had many silk cases from different brands, but this is by far the most luxurious and quality product of them all. Will be repurchasing.
