Understanding Momme Weight: Why It Matters for Your Custom Silk Scarf
Quick answer: Momme (pronounced “mummy”) is the traditional unit used to measure how much silk is in a fabric — specifically, how many pounds a standard bolt measuring 45 inches wide by 100 yards long would weigh. One momme equals approximately 4.34 grams per square metre. Higher momme means more silk per square metre: a denser weave, more weight, deeper colour, and greater durability. For custom scarves, 8mm chiffon is lightweight and sheer; 14mm twill or crêpe de chine is the mid-weight standard; 16mm and above produces a noticeably more substantial, premium result.
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 produces a result that disappoints. Here is everything you need to understand it.
Momme is the measure of silk that separates an informed buyer from one who is relying on faith. Once you understand it, you cannot unknow it.
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 metre.
So an 8mm chiffon fabric weighs around 35 grams per square metre, while a 14mm twill weighs around 61 grams per square metre, and a 22mm fabric weighs around 95 grams per square metre. The higher the momme, the more silk fibre has been woven into that square metre of fabric. More fibre means a denser weave, heavier fabric, more opacity, richer colour absorption, greater durability, and a more substantial hand feel.
This is not the same as silk quality. Momme measures density, not the grade of the raw silk fibre. Momme is one measure of quality, not the only one.
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 colour 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 behaviour — heavier fabric holds a hand-rolled hem with more substance.

What momme weights does LS Silk NZ offer?
LS Silk NZ offers three standard fabric choices. Silk chiffon at 8mm is the lightest option — sheer, weightless, and completely fluid. At approximately 35 grams per square metre, 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 metre. This weight falls within the range most commonly used for premium scarves by heritage houses. Heavier weights — 16mm and above — are available on request.

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 $130 benefits from 14mm or higher because the hand feel of the piece needs to justify the price.

Frequently asked questions
What is momme weight in silk?
Momme (abbreviated mm) is the traditional unit used to measure silk fabric density. One momme equals approximately 4.34 grams per square metre. Higher momme means more silk fibre per square metre — a denser, heavier, more opaque fabric that holds colour more deeply.
What momme weight is best for a silk scarf?
Most quality silk scarves are produced in the 12–16mm range. LS Silk NZ offers 8mm chiffon, 14mm twill and crêpe de chine, and heavier weights up to 18mm and above on request.
Does higher momme mean better quality silk?
Not automatically. Momme measures fabric density, not the quality of the raw silk fibre. The right momme is the one that suits the intended purpose.
How does momme weight affect the colour of a printed silk scarf?
Higher momme fabric absorbs dye more deeply. A design printed on 8mm chiffon will appear softer and lighter than the same design on 14mm twill at the same dye concentration.
What is the difference between 8mm, 14mm, and 16mm silk for scarves?
At 8mm, silk chiffon is sheer and fluid. At 14mm, twill and crêpe de chine are semi-opaque with good colour depth and structure. At 16mm and above, the fabric is noticeably heavier, fully opaque, with richer colour. The difference is perceptible by touch.
