How to Measure Your Pillow for the Right Silk Pillowcase Fit
For a good fit, measure your pillow's width and length, compare them with the seller's stated dimensions, and check that the opening closes without stretching the silk. A size name alone does not tell you everything you need to know.
This guide walks you through the measurements and fit checks to make before choosing a silk pillowcase, whether you are replacing a favorite case or trying silk for the first time.
How to measure your pillow
Start with the pillow you actually sleep on. Remove its pillowcase and lay the insert on a flat surface in its normal shape. Look for a size label first: the manufacturer's stated dimensions are a useful starting point.
- Measure the length from one outer seam to the opposite seam.
- Measure the width in the other direction.
- Keep the tape straight rather than wrapping it around the curved surface.
- Write down both measurements and the units you used.
A soft, curved pillow is not a rigid rectangle, so a home measurement is approximate. If your result differs noticeably from its label, measure again without stretching or heavily compressing the filling. For a contoured or unusually shaped pillow, check the pillow manufacturer's case recommendations.
Compare dimensions, not just size names
A label such as Queen is a starting point, but the actual dimensions are what you need to compare. When shopping across countries or brands, look for both width and length instead of assuming that a familiar name guarantees a fit.
Also check what a size chart describes: the finished pillowcase, or the pillow insert it is designed to hold. If that is unclear, ask before ordering. Closure construction and the fullness of the insert can affect the fit even when the numbers look similar.
For example, a pillow labelled 20 × 30 inches is a sensible starting match for a case intended for a 20 × 30-inch pillow. A shorter insert may leave spare fabric at the end, while a longer insert can put tension on the opening. Do not add a fixed number of extra inches unless the seller's sizing instructions tell you to.
What a comfortable fit looks like
The case should cover the pillow without needing to stretch the fabric to close it. Once the insert is inside, gently distribute the filling and check the corners, seams, and opening.
- At the corners: the pillow should sit naturally, without hard pulling on the seams.
- Across the surface: some soft drape is normal. Silk does not need to look pulled tight.
- At the opening: a zipper should close gently, or an envelope flap should overlap without being forced apart.
If the case feels tight, pause and reposition the pillow. If it still requires force, recheck the measurements rather than pulling harder. An unusually full or firm pillow can be less forgiving than a softer one.
Check the opening and closure
With a zippered pillowcase, open the zipper fully before inserting the pillow. Guide the corners into position, move any loose fabric away from the teeth, and close the zipper without pulling against tension.
With an envelope closure, make sure the pillow sits behind the internal flap. A case that appears long enough may still gape if the insert is too full for the overlap.
Our guide to hidden zipper and envelope closures explains the construction differences in more detail. Size and closure should be considered together.
The Muse & Airy pillowcase size
The Muse & Airy 22 Momme Mulberry Silk Pillowcase is currently listed in Queen size: 20 × 30 inches / 51 × 76 cm. The centimetre figures are rounded equivalents. Compare those measurements with your own pillow before ordering.
The product has a hidden, color-matched zipper and silk on both exterior sides. Each purchase includes one pillowcase; the pillow insert is not included. The product page notes that slight measurement variations are possible because of the fabric's softness.
If you are choosing between different constructions, read our explanation of double-sided silk pillowcases. Check the live product page for the latest size information.

A quick checklist before you order
- Record your pillow's width and length.
- Confirm whether the seller's measurements describe the case or its intended insert.
- Compare measurements in the same units.
- Consider the pillow's shape and fullness.
- Check the closure and the number of pillowcases included.
- Read the care instructions before the first wash.
Do not plan to shrink a loose case into shape. Follow the attached care label and the product's instructions. Our silk pillowcase washing guide provides more care context.
Frequently asked questions
Can I use a larger pillowcase on a smaller pillow?
It may cover the pillow, but extra fabric can gather or leave an empty end. Whether that feels comfortable is personal. A closer size match is a better starting point if you prefer a neat fit.
Should I size down for a smoother appearance?
A smaller case can strain the seams or opening. Choose a size intended for your pillow and allow the fabric to drape naturally.
Does 22 momme tell me the pillowcase size?
No. Momme describes silk fabric weight, not the finished width and length. Check the dimensions separately.
What if my pillow has no size label?
Measure both directions seam to seam, then compare your measurements with the seller's guide. For an unusual shape or a borderline fit, share the dimensions with the seller before ordering.
