Silk fabric weights (momme): Our duvet covers, fitted sheets, flat sheets and cushion covers are crafted from 22 momme Grade 6A silk. Our silk pillowcases are crafted from 25 momme Grade 6A silk, with sizes shown in the table below. All our silk is finished with our contemporary matte finish, loved by both men and women alike.

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.

Our bedding sets bring together 22 momme silk bed linen and 25 momme silk pillowcases, all in Grade 6A Mulberry silk with our signature soft matte sheen. See the product description for the pieces included in this set.

Customer photo review of Charcoal Silk Duvet Set

I am a lawyer. So I do due diligence. I was searching for high quality silk in different colours that matches up to the European feel and quality. What I love about MayfairSilk is that the silk is preshrunk and the colours used are non toxic- and it feels sooo good. Also I know the woman behind this business and they have done their research. It’s filling a gap in the market to meet one of the fundamentals of good quality life which is ‘good quality sleep’. A business to applaud. 👏🏼

Charcoal Silk Duvet Set

It felt that I had to get a Phd in silk to understand what I really needed for my silk sheets. I have been burnt by several dodgy brands until I came across Mayfairsilk - in my opinion it is the best silk bedding. The Mulberry silk sheets are naturally hypoallergenic , dust mite repelling and ideal for sensitive skin. It feels soft and the best part is that they are machine washable and long lasting

Charcoal Silk Duvet Set

The charcoal duvet set delivers comfort and understated luxury. The fabric feels smooth, breathable, and cool against the skin, elevating sleep quality. Its elegant matte finish and rich tone complement any bedroom aesthetic, while the craftsmanship ensures durability. A refined upgrade that feels as good as it looks.

Thank you. This silk bed sheets set has exceeded my expectations. Very soft and not so slippery as other knock offs out there.

Was introduced to Mayfairsilk via Verve Rally and my wife has fallen in love with the brand. She now wants us to buy the sheet set for the guest bedroom! It is the best.

I'm really happy I took the plunge and invested in these charcoal silk sheets. I’ve never experienced sleep like this before.

Soothing to my silk, joy to my soul. Truly these bed sheets have lasted me 5 years and I come home to them with a smile :)

Charcoal Silk Duvet Set

I recently treated myself to one set of pillowcases and silk bedding , and I can honestly say they are a complete revelation. Made from the finest mulberry silk, they feel softer and more comfortable than anything I have slept on before. The natural properties of silk keep my skin cool and my hair tame and I wake up looking far fresher than I ever did with cotton. Washings is easy with care instructions that came with the silk. The silk bedding is not just a little upgrade, they are genuinely better than cotton pillowcases and bedding in every way - once you try them, you will never want to go back.
