What Does Momme Mean?

Momme (mm) is a traditional Japanese unit of measurement used to determine the weight and density of silk fabric. It is similar to how cotton sheets are measured with thread count, but instead of threads per inch, momme refers to the actual weight of silk per 100 yards of fabric (approximately 36 inches wide).

  • The higher the momme, the denser and heavier the silk.

  • More momme means more silk fibers woven tightly together, resulting in a stronger, glossier, and more durable fabric.

  • Lower momme counts are lighter and more breathable, making them ideal for summer clothing and delicate accessories.

For example:

  • 8 momme silk feels featherlight, perfect for scarves.

  • 19 momme silk is widely used for pillowcases and bedding because it balances durability with comfort.

  • 30 momme silk is extremely dense and luxurious, designed for high-end bedding and long-lasting wear.

👉 In short: Momme = silk weight = silk quality (when combined with grade and weave).

Why Momme Matters for Silk Products

When shopping for silk pillowcases, sheets, or clothing, you might wonder: Does momme really make a difference?The answer is yes. Momme determines the texture, durability, and comfort level of silk.

  • Durability – When it comes to silk, durability is directly related to momme count. A higher momme means that more silk fibers are tightly woven into every square inch of fabric. This density makes the silk less prone to tearing, thinning, or losing its sheen over time. Higher momme silk is denser and lasts longer. For example, a 22 momme pillowcase can last nearly twice as long as a 19 momme pillowcase.

  • Feel – The feel of silk is one of the main reasons it is so beloved, and momme weight plays a huge role in how silk touches the skin. Lighter momme silk (16mm–19mm) is airy, breathable, and feather-soft, making it ideal for those who enjoy a delicate, almost weightless fabric against their skin. Lighter momme silk is airy and soft, while heavier momme silk feels richer, more luxurious, and has a deeper luster.

  • Seasonality – The final factor that makes momme weight so important is seasonality. Different momme counts serve different climates and personal comfort preferences. Lower momme silk (16mm–19mm) is perfect for summer, while higher momme silk (25mm–30mm) provides warmth in winter. Mid-range silk weights such as 22mm strike a balance, offering year-round versatility by staying cool enough in summer while still providing warmth in colder months.

  • Price – Since higher momme silk requires more raw silk fibers, it is more expensive.

This is why choosing the right momme count is essential depending on your purpose—whether it’s bedding, fashion, or accessories.
