Yarn Count Conversion: Ne, Nm, Tex and Denier Explained

18 June 2026 by

Yarn count tells you how fine or coarse a yarn is, but different systems are used around the world. Knowing them avoids costly miscommunication when sourcing.

Indirect systems (count rises as yarn gets finer)

  • Ne (English cotton count) — the most common for cotton; higher Ne = finer yarn (40s is finer than 20s).
  • Nm (metric count) — length per unit weight; higher = finer.

Direct systems (count rises as yarn gets coarser)

  • Tex — grams per 1,000 metres; higher Tex = heavier yarn.
  • Denier — grams per 9,000 metres; common for filament yarns.

Handy conversions

  • Ne to Tex: Tex ≈ 590.5 ÷ Ne
  • Nm to Tex: Tex ≈ 1000 ÷ Nm
  • Denier to Tex: Tex = Denier ÷ 9

Why it matters

If your spec is in Ne but your supplier quotes in Tex or Denier, a quick conversion keeps everyone aligned on the same yarn. Always confirm the system alongside the number.
