What is Momme?
The Essential Guide to Silk Quality Measurement
Silk has long been revered as the “queen of fabrics,” prized for its luxurious texture, natural sheen, and timeless elegance. But beyond its aesthetic appeal, silk is also a highly technical textile, measured and graded in ways that may be unfamiliar to the average consumer. One such term is momme (pronounced “momm-ay”), a unit that defines silk’s weight and quality. Whether you’re a fashion enthusiast, a home decorator, or simply curious about textiles, understanding momme can help you make informed choices when purchasing silk products.
Momme is pronounced as “mom-ee” and abbreviated as “mm.” Please note that it should not be confused with the unit of length, millimeters. Momme is a specific measurement unit used in relation to silk fabric to indicate its thickness, quality, and density. The term “momme” originates from the Japanese words “mom” meaning “hundred” and “me” meaning “yards.”
In Japan, it is more accurately written as “monme,” but due to transliteration, it became known as “momme” and gained popularity in the Western world. In Japan, it represents the weight of a 100-yard-long, 45-inch-wide silk fabric, typically measured in pounds.
Why Does Momme Matter?
1. Quality Indicator
Higher momme silk is typically stronger, more lustrous, and less prone to tearing. For example, 19 mm silk bed sheets will outlast 12 mm sheets.
2. Comfort & Performance
Lower momme (6-12 mm): Lightweight and cool, ideal for summer wear.
Higher momme (16-22 mm): Warmer, with better moisture-wicking properties.
3. Price Determination
Since higher momme silk requires more raw material, it’s generally more expensive. A 22 mm silk pillowcase costs significantly more than a 16 mm one.
Silk fabrics typically fall into these momme categories:
6-12 mm (Lightweight)
Used for delicate scarves, lingerie, and lightweight clothing.
Sheer and breathable but less durable.
12-19 mm (Medium Weight)
Ideal for blouses, dresses, and standard bedding.
Balances softness with moderate durability.
19-22 mm (Heavyweight)
Found in premium bedding, robes, and upholstery.
Thicker, more insulating, and long-lasting.
22+ mm (Ultra-Heavyweight)
Reserved for luxury items like high-end duvets or ceremonial kimonos.
Extremely durable but less breathable.
How is Momme Calculated?
Momme measures the weight of a piece of silk that is 100 yards (91.44 meters) long and 45 inches (1.14 meters) wide.
1 momme = 4.3056 grams per square meter (GSM)
Higher momme = Heavier, denser silk
Momme vs. Thread Count
Momme weight is a unit of measurement used to indicate the weight of silk fabric, and it is closely tied to the thickness and density of the silk. The higher momme weight indicates denser, heavier fabric.
Thread count is utilized to describe the density of cotton fabric, specifically referring to the number of warp and weft threads per square inch. Thread count is associated with the perceived quality and smoothness of cotton fabric, with a higher count resulting in finer and softer fabric.
Momme Weight Range for Different Silk Fabrics

| Silk Satin | 9 – 40 momme |
| Silk Twill | 10 – 28 momme |
| Silk Chiffon | 6 – 12 momme |
