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.

Oyster Grey Pure Silk Pillowcase

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 Oyster Grey Pure Silk Pillowcase

Beautiful gift of pure silk pillowcases … I really love the quality that Mayfairsilk offers

Oyster Grey Pure Silk Pillowcase

Beautiful pillow cases. Pure quality. I previously purchased silk pillow cases from another company and thought that this was as good as it gets. This was until I decided to purchase from Mayfair. A beautiful colour (mine) which is a soft minky grey. A bit pricier, but you do get what you pay for. Delivered very quickly in a lovely presented gift box should you wish to gift to someone ❤️

Oyster Grey Pure Silk Pillowcase

Absolutely beautiful. Love the colour, a subtle mink grey. Fantastic quality, very well made. Will be looking to make another purchase in the near future

Oyster Grey Pure Silk Pillowcase

I was a little dubious at first spending so much money on two pillowcases but it really was well worth it. Beautiful silk and great options of colours. Will use Mayfair Silk again as delivery was prompt also.

Oyster Grey Pure Silk Pillowcase

I am really happy with my pillowcase, it is so soft and cool and looks lovely. My hair gets quite frizzy in the morning but I have definitely noticed a difference in the morning as my hair is less frizzy and more manageable. I would definitely recommend investing in one.

Oyster Grey Pure Silk Pillowcase

Absolutely fabulous!!! Benefits my hair and my skin and is (both are) so easy to care for!!! Yaaay!

Oyster Grey Pure Silk Pillowcase

Having read reviews of Mayfairsilk, I wanted to purchase one to experience it first hand. Without a doubt, my hair feels softer and the quality of my sleep has improved on this grey silk pillowcase. Keeps me comfy and cool all night.

Oyster Grey Pure Silk Pillowcase

Gorgeous silk and I absolutely love this silk pillowcase - my hair and skin are visibly better

Oyster Grey Pure Silk Pillowcase

Ordered over the Christmas period and delivery companies were very pressed to meet delivery deadlines, however, Mayfair Silk went the extra mike and pulled out all the stops to get our beautiful silk pillowcases to us as speedily as possible. Thank you!
