Denier & Tex FAQ
Everything you need to know about textile linear density measurements and conversions.
To convert Denier to Tex, simply divide the Denier value by 9. The formula is: Tex = Denier / 9. For example, 90 Denier is equal to 10 Tex.
Both measure the linear mass density of fibers, yarn, or thread. Denier is the weight in grams of 9,000 meters of the material, while Tex is the weight in grams of 1,000 meters. Tex is the official ISO standard, while Denier is traditionally used for silk and synthetic filaments.
Dtex (Decitex) is the weight in grams of 10,000 meters of yarn. It is the most common unit for synthetic fibers and microfibers. To convert Denier to Dtex, divide the Denier by 0.9 (or multiply the Tex value by 10).
Generally, yes. A higher Denier number indicates a thicker, heavier, and more robust yarn or fabric. For example, 1000D nylon is significantly stronger and more abrasion-resistant than 200D nylon, though it will also be heavier and less flexible.
