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.

Pastel Blue 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.

Beautiful colours and fitted perfectly. My second or third purchase and never been disappointed.

Pastel Blue Pure Silk Pillowcase

Bought this as a gift and was very happy with the look and feel of this pillow case.

Pastel Blue Pure Silk Pillowcase

Bought as a gift so cannot show photos but the pale blue silk is a stunning colour, beautifully presented and I look forward to gifting this, as I have many times before from the Mayfair Silk collection, excellent products.

Pastel Blue Pure Silk Pillowcase

The pillowcase is amazing, it feels really good on my skin and very good quality. The only negative is that it slips off easily - it would be good if it had a popper or zip at the opening to prevent this.

Pastel Blue Pure Silk Pillowcase

Love the difference it has made to my hair - soft and no frizz when I awake from slumber

Pastel Blue Pure Silk Pillowcase

I liked the color. Great quality along with the white colored pillow case we got. It lived up to the expectation of being superior quality to a cheap silk pillowcase we ordered from another shop.

Pastel Blue Pure Silk Pillowcase

It took me a few weeks to notice the difference sleeping on silk has made to my hair and skin. Softer, smoother and more radiant. Quality product all the way!

Pastel Blue Pure Silk Pillowcase

The silk is marvellous. The colour is subtle and soothing- a lot better in real life than what I can see on this screen. Highly recommend.

Pastel Blue Pure Silk Pillowcase

The pillowcases are the best. I have eczema at the back of my neck which I feel has been under control now since I switched to sleeping on mayfairsilk.

Pastel Blue Pure Silk Pillowcase

I’ve gotten used to stroking my MayfairSilk pillowcase right before bedtime each night - everyday luxuries.

Pastel Blue Pure Silk Pillowcase

I bought this pillow case just before starting chemotherapy - it had been recommended as a way to lessen stress on hair. I was very uncertain about how it would feel after years of sleeping on cotton, but I love it. I have got used to my head and face gliding rather than rubbing across the fabric and it is comforting and very comfortable.

Pastel Blue Pure Silk Pillowcase

I've tried some dodgy silk pillowcases before - this one from mayfairsilk is a game changer. The best quality out there!

Pastel Blue Pure Silk Pillowcase

Birthday gift for my friend- she loves it and also the little note that went along with it!

Pastel Blue Pure Silk Pillowcase

I am very happy with my Mayfair silk pillowcase, and although I have only used it for a few nights - already I have noticed an improvement in my complexion and in time I will probably purchase another.

Pastel Blue Pure Silk Pillowcase

The pillowcase was well worth the wait. The finish and texture is superb and is superior to anything we have previously used. It has assisted also with improved sleeping patterns. Considering a further purchase. Thanks.

Pastel Blue Pure Silk Pillowcase

Amazing personal customer service. Pillowcase arrived the next day, beautifully packaged. Would definitely recommend!
