What does momme actually measure?

Momme — abbreviated as mm in the silk industry — is a traditional Japanese unit of weight that became the global standard for measuring silk density. The word derives from the old Japanese monme, a unit of mass equal to 3.75 grams. In practical terms, momme measures the weight in pounds of a piece of silk fabric sized 45 inches wide by 100 yards long. One momme equals approximately 4.34 grams per square meter. So an 8mm chiffon fabric weighs around 35 grams per square meter, while a 14mm twill weighs around 61 grams per square meter, and a 22mm fabric weighs around 95 grams per square meter. The higher the momme, the more silk fiber has been woven into that square meter of fabric. More…

Understanding Momme Weight: Why It Matters for Your Custom Silk Scarf

Q: How does momme affect a silk scarf?

For scarves specifically, momme has five practical consequences. The first is drape — lower momme silk floats freely while higher momme falls in a more deliberate, structured way. The second is opacity — at 8mm chiffon is translucent; at 14mm, twill and crêpe de chine are semi-opaque. The third is color depth — the denser the weave, the more dye it absorbs and the richer the print appears. The fourth is durability — higher momme silk is more resistant to wear and repeated washing. The fifth is hem behavior — heavier fabric holds a hand-rolled hem with more substance. Read our guide to hand-rolled vs machine hem to see why this matters.

Q: What momme weights does LS Silk offer?

LS Silk offers three standard fabric choices. Silk chiffon at 8mm is the lightest option — sheer, weightless, and completely fluid. At approximately 35 grams per square meter, it is barely there in the hand. Silk twill and silk crêpe de chine, both at 14mm, are the mid-weight standard at approximately 61 grams per square meter. This weight falls within the range most commonly used for premium scarves by heritage houses. Heavier weights — 16mm and above — are available on request. To understand how each fabric behaves at its momme weight, read our full guide to silk twill vs crêpe de chine vs chiffon.

Q: Is a higher momme always worth paying for?

Not always. The right momme is the one that serves the intended purpose of the finished piece. An artist creating a chiffon scarf to be worn loosely in summer does not need 18mm fabric — the lightness of 8mm chiffon is precisely the point. A museum gift shop commissioning a retail scarf retailed at $120 benefits from 14mm or higher because the hand feel of the piece needs to justify the price.

Quick answer: Momme weight is the measure of how much silk is in a fabric. One momme equals about 4.34 grams per square meter (0.13 ounces per square yard), so a higher number means a denser, heavier cloth with deeper color and more body. For custom silk scarves, 14 momme is the classic weight, and 16 momme is noticeably more substantial. LS Silk offers silk twill at 14 and 16 momme and crêpe de Chine at 14 momme.

Every silk product you have ever bought had a momme weight. Most of them just never told you what it was. The number matters, not because higher is always better, but because the right weight for the wrong purpose disappoints.

What does momme measure?

Momme is a traditional Japanese unit of weight that became the worldwide standard for silk. One momme equals about 4.34 grams per square meter of fabric. You will sometimes see it shortened to “mm”, which has nothing to do with millimeters.

Momme	Grams per square meter	Typical use
8	About 35	Sheer chiffon scarves
14	About 61	Classic silk scarves
16	About 69	Heavier, more substantial scarves
22	About 95	Pillowcases and bedding

The higher the momme, the more silk is woven into each square meter. More silk means a denser weave, more weight, more opacity and richer color.

Momme is not the same as quality. It measures density, not the grade of the silk fiber. It is one measure of a fabric, not the only one.

How does momme affect a silk scarf?

Drape. Lighter silk floats. Heavier silk falls in a more deliberate, structured way.
Opacity. At 8 momme, chiffon is translucent. At 14 momme and above, twill and crêpe de Chine are far more opaque.
Color. Denser silk takes up more dye, so the print looks richer.
Durability. Heavier silk stands up better to wear and washing.
The hem. Heavier silk makes a slightly fuller hand-rolled hem. Read our guide to hand-rolled vs machine hems.

What momme weights does LS Silk offer?

In the Custom Studio you can choose:

Silk twill, 14 momme. The classic silk scarf cloth, balanced between structure and drape.
Silk twill, 16 momme. More substantial, with greater body and weight.
Crêpe de Chine, 14 momme. Softer and more fluid, with a matte surface.

Silk chiffon at 8 momme and silks heavier than 16 momme are available by quote. To see how each cloth behaves, read our guide to silk twill vs crêpe de Chine vs chiffon.

Is a higher momme always worth paying for?

Not always. The right momme is the one that serves the purpose of the finished piece. A light scarf meant to be worn loosely on a summer evening does not need heavy silk. A scarf sold in a gallery shop for more than $100 benefits from 16 momme, because the feel in the hand needs to justify the price.

The price difference is small. On a 25.6 in (65 cm) scarf in a run of 30 to 49 pieces, twill at 16 momme costs about $3 more per piece than twill at 14 momme. See our cost guide.
