How to choose the right pillowcase size?

Standard pillowcases measure 65x65 cm for square pillows and 50x70 cm for rectangular pillows. Pillowcases in 40x40 cm are suitable for smaller square pillows, for example those used in children’s bedrooms.

Some sleepers prefer wider rectangular pillows such as Queen pillows, which require a 50x80 cm pillowcase.

Beyond these common sizes, there is a wide variety of pillows with varying dimensions. Ergonomic pillows, designed to support specific areas, often require a dedicated pillowcase.

This is particularly the case for memory foam pillows, which contour to the sleeper’s head and neck.

Finally, there are also pillowcases specifically designed for bolsters.

Looking to replace your pillows? Sylvie Thiriez offers a range of pillows in 40x60, 50x70 and 65x65 cm formats, as well as bolsters.

Soft, ultra-soft, medium or firm — it’s up to you to choose the model that suits you best.

Feel free to consult our dedicated buying guide. It will help you select the right pillow based on your firmness preferences and sleeping position.

There is a wide choice of pillowcase sizes available, which can sometimes make it difficult to find your way.

To avoid mistakes, the best approach is to check your pillow’s measurements before purchasing in-store or ordering online.

Simply measure the length and width using a measuring tape.

This will allow you to determine in just a few minutes whether a standard 65x65 or 50x70 cm pillowcase is sufficient or whether you need a cover designed for special pillows.

If you sleep on an ergonomic pillow (wave-shaped, memory foam, latex or similar), a specific 40x60 cm pillowcase may be required.

Is your pillow particularly voluminous? Consider choosing a slightly larger pillowcase to make it easier to insert your pillow, for example a Queen size 50x80 cm pillowcase or even a King pillowcase.

Does your pillow have an unusual shape or dimensions and you’re struggling to find the right pillowcase? Contact Sylvie Thiriez customer service and order a custom-made cotton or percale pillowcase in the size of your choice.

Some people choose extra-large pillows to complement a King size bed, very common in North America, or simply out of preference for these wide pillows measuring 51x92 cm.

If this is your case, you’ll need a King pillowcase. At Sylvie Thiriez, we offer square pillowcases in 80x80 cm or rectangular pillowcases in 80x100 cm, suitable for most XL pillows.
