Taille de taie d'oreiller : 65x65, 50x70 et comment choisir la bonne
65x65, 50x70, 60x60 : les formats réels, la règle de correspondance oreiller/taie, et pourquoi une taie en soie trop juste ne se rattrape pas.
Choosing a pillowcase should be the simplest part of the purchase. In practice it is where most mistakes happen: a case too tight that compresses the pillow, one too large that creases under the cheek, or a "standard size" that does not match the pillow you actually own.
The two standard pillowcase sizes in France
Two formats cover most French beds: the square 65x65 cm pillowcase, the historic French format, and the rectangular 50x70 cm, often called the "American pillow", common in hotels. Other sizes are far from rare: 60x60 and 50x50 in square, 45x70 and 40x60 in rectangular.
Manufacturers do not agree on "the" standard
This is the point buying guides leave out. Bonsoirs states that for square pillows "the most common dimensions are 65x65 cm". Tediber states that "a standard pillow is a 60x60 cm square pillow", described as "the most widespread size in France". Two French bedding brands, two opposite answers.
The practical conclusion: the word "standard" means nothing on its own. Measure your pillow flat, without compressing it, edge to edge including the seams.
Which pillowcase for which pillow
| Your pillow | Pillowcase | Note |
|---|---|---|
| 65x65 cm (square) | 65x65 cm | The best-selling format in France |
| 60x60 cm (square) | 60x60 cm | Common, and often confused with 65x65 |
| 50x50 cm (square) | 50x50 cm | Small format, guest rooms |
| 50x70 cm (rectangular) | 50x70 cm | The "American" size, standard in hotels |
| 45x70 cm (rectangular) | 45x70 cm | Common on ergonomic pillows |
| 40x60 cm | 40x60 cm | Children, travel, spare |
The rule: same size as the pillow, unless it is plump
The base rule is the one bed linen makers give: match the pillow's dimensions. There is one exception, and it concerns many people — very plump pillows filled with down. On those, an exact-size case gives a compressed look and pulls on the seams. Embrin advises taking a case 4 to 5 cm larger on one of the two sides.
How to choose between the two? Look at the filling. A foam ergonomic pillow has a fixed volume: exact size is right. A down pillow recovers volume with every shake: the 4-5 cm margin stops you crushing it.
What the stated size does not tell you
The advertised dimension is the inner edge-to-edge measurement, and it excludes decorative borders. A 65x65 pillowcase with a flange therefore measures more than 65 cm overall. When comparing two products, compare the inner measurement.
The closure matters too. An envelope flap holds by the fold of the fabric — simple, but it needs a well-fitted case not to gape. A zip holds a plump pillow with no slack, at the cost of a rigid part you may feel under your head.
Silk: a pillowcase that is too tight cannot be recovered
On cotton, an error of a centimetre or two is forgiven: the fabric gives and recovers in the wash. On a silk pillowcase, it is not — and this is a mechanical property of the fibre, not a quality issue.
Silk elasticity is moderate to poor: stretched even slightly, it does not fully return to its original size. A silk pillowcase forced onto an over-sized pillow keeps that mark permanently, visible at the corners where tension is highest.
The practical consequence is one sentence: when hesitating between two sizes in silk, take the larger one. The 4 to 5 cm margin for a plump pillow matters even more here than on cotton.
A second reflex, at washing time: silk loses up to 20% of its strength when wet. Never force a still-damp case onto a pillow — that is exactly when the fibre copes least well. The method is in our guide to washing silk.
Size, momme and weave are three different things
- The dimension (65x65, 50x70) — the fit to your pillow.
- The momme — the weight of the fabric, so its density. See our article on silk momme.
- The composition — the actual material, as a percentage. "Satin" is a weave, not a fibre: it can be silk or polyester.
Frequently asked questions
What is the standard pillowcase size?
There is no single standard in France, but two dominant formats: 65x65 cm for square cases and 50x70 cm for rectangular ones. Manufacturers themselves disagree — some present 65x65 as the most common, others 60x60. Measure your pillow rather than trusting the word "standard".
How do I measure my pillow?
Lay it flat without compressing it and measure edge to edge, seams included, both ways. Note that the sizes quoted by pillowcase makers are the inner measurement, excluding decorative borders.
Can I put a 65x65 case on a 60x60 pillow?
Yes, but the case floats and the excess fabric creases, including under the cheek. On a very plump pillow that slight surplus is an advantage; on a firm or foam pillow, prefer the exact size.
What size of silk pillowcase should I choose?
The same as for any other material, with one important nuance: silk elasticity is moderate to poor, and a case stretched by force will not recover. When in doubt between two sizes, take the larger one, especially on a down-filled pillow.
