Silk pillowcase size chart

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.

Ivory 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 Ivory Pure Silk Pillowcase

Resting your cheek on 25 momme 100% mulberry silk is next level luxury and a wonderful sleep experience you can treat yourself to at home. Cooling, soothing, soft and kind to your skin and hair and like me you’ll probably kick yourself for lying on ultra-drying cotton all these years. I have a spare that I take away with me on holidays and weekend hotel breaks as I just can’t sleep on anything else now. MayfairSilk’s 25 momme pillowcases have truly spoiled me! They make a beautiful gift too as most people wouldn’t think to buy something as indulgent as this for themselves.

You know that you have married right when your husband gifts you the silk pillowcase you’ve been dreaming of for my birthday - and yes the flowers are good touch too. A very happy wifey.

Customer photo review of Ivory Pure Silk Pillowcase

I treated myself to a Mayfairsilk pillowcase for my birthday just past. I love it .. so much so that I took it with me on a recent two-day trip to London. I haven't had it long enough to know if it is helping my skin but it has meant better sleep quality - I don't seem to toss and turn so much and possibly because of that my hair is much less tangled in the morning. I am now thinking of buying one for my sister in Australia.

Beautiful pillowcase set to complete my Christmas present - can't wait to open the lovely packaging and use it! I only rest my head on silk now for the unmatched comfort, smoothness and coolness!

Customer photo review of Ivory Pure Silk Pillowcase

I'm obsessed. It really takes sleep to another level. Great quality. It helps keep the skin hydrated, which someone with sensitive, dry, eczema-prone skin like me will appreciate. The prints are beautiful, but honestly, who else on the market has piping (such a great detail) or 35cm deep fitted sheet or 65x65cm pillowcases? I am in love and will definitely be ordering more.

Why have cotton when you can have silk I really love my silk pillowcase. Thank you it is perfect.

Ivory Pure Silk Pillowcase

THE BEST silk pillowcase I have ever had. This is luxury beyond means. I’m ordering four more to complete my bedding. My sleep has definitely improved and woken up without dry skin… worth the splurge.

Ivory Pure Silk Pillowcase

Love the new packaging …and the silk pillowcase is my favorite. The last one from Mayfaisilk lasted me 5 years.

Ivory Pure Silk Pillowcase

I bought it as an early Christmas gift so I can let you know in the new year if it was well received.

Ivory Pure Silk Pillowcase

Stunning quality and beautiful presentation! The items arrived in gorgeous luxury packaging and the silk feels amazing to the touch. It’s clear that Mayfairsilk pays attention to every single detail. I’m already in love with them!

Ivory Pure Silk Pillowcase

The product arrived quickly and I am happy with the quality of the silk. Love the feel of the pillowcase on my face.

Ivory Pure Silk Pillowcase

I’ve got four of these pillowcases now, so I can rotate them and they are beautiful. Thicker and glossier than some I’ve had, but soft and comfortable. Delivery was strange, as with my first order. DPD said next day delivery, then at the last minute it was “sorry, there’s a delay” and they came the day after. Annoying when you’ve stayed in all day! Why don’t Mayfair just say that it’s 48 hour delivery, which is still great and we’d all know where we stood. But the pillowcases are beautiful, which is the main thing, and they wash well.

Ivory Pure Silk Pillowcase

I love these Ivory pillowcases and the 25 momme silk is wonderful quality. The only let down is the 11 cm envelope opening. Ones I’ve had in the past had 18 cm flaps, which were a better fit for my full pillows. But otherwise I am very impressed with the quality and will get two more, when finances allow.

Ivory Pure Silk Pillowcase

I’ve genuinely noticed smoother, less frizzy hair and skin that feels beautifully hydrated by morning. It strikes that rare balance between everyday comfort and quiet, understated luxury-and once you’ve slept on Mayfairsilk, going back to cotton simply isn’t an option.

Ivory Pure Silk Pillowcase

The most beautiful silk pillowcase, such a lovely ivory natural colour and silky hair in the morning.

Very helpful personal service to ensure prompt delivery for a birthday. Lovely product too.
