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.

Love this material, will never be going back to cotton! They are quite baggy for my pillowcases but if you fold it under you can’t tell

Customer photo review of Iridescent Garden Pure Silk Pillowcase

Having used other high end silk pillowcases which were good but not 25 momme. My research led me to Mayfairsilk. I ordered two and having used it, all I can say is Wow! I am so impressed with the quality. I have washed it as advised and it a pure joy to sleep on the pillowcase. I would highly recommend Mayfairsilk without hesitation.

I was delighted to find these pretty print silk pillowcases . I didn't want plain block colour. I wish they has an Oxford style though. That would be even better.

Customer photo review of Iridescent Garden Pure Silk Pillowcase

Feels wonderful … the only trouble is that now I have to put up a fight each night with my dog as she has claimed it!

Iridescent Garden Pure Silk Pillowcase

Beautiful pattern and fabric, I have had silk pillowcases before but this one feels particularly heavy and luxurious.

Iridescent Garden Pure Silk Pillowcase

I have ordered from Mayfair silk previously and have not been disappointed. I always take a pillowslip with me on my travels as it aids sleep. The only downside is that the slip closure could be a little deeper to prevent it sliding. It would be even better if there were more colours to choose from.

Iridescent Garden Pure Silk Pillowcase

Delighted with my mulberry silk pillowcase. The mulberry silk is superb and so sumptuous to sleep on and it came beautifully packaged.

Iridescent Garden Pure Silk Pillowcase

It fits very well and seems to keep my hair looking quite reasonable so that I wake up in the morning in a not too dishevelled way!! Beautifully packed!

Iridescent Garden Pure Silk Pillowcase

Very well made. you can tell the difference between mayfair silk and cheaper shops silk. its luxurious and the the way it flows is sublime. I can go to bed with frizzy hair, and the next day its been tamed. Thats my own experience. I wish I could afford the sheets and quilt cover. Saving up my pennies for it.

Iridescent Garden Pure Silk Pillowcase

Really love this- bought for my friend’s birthday- she’s a big gardener so utterly perfect print for her. She was blown away by it and already loves sleeping on it and says her hair is way less frizzy in the morning and her face all smooth! That was a win!! 😃

Iridescent Garden Pure Silk Pillowcase

This is my third beautiful pillow slip I previously purchased two with the birds. This one is for my friend who is having Chemotherapy and she loves it too.
