Summary

Convert textile fiber fineness in denier to fabric weight in GSM, plus Tex and dtex, with a reference table of common fabrics.

How it works

  1. Enter the denier value and thread count per cm² into the input fields.
  2. GSM is calculated as (Denier × thread count per cm²) / 9.
  3. Tex is derived as Denier / 9; dtex is Denier × 10 / 9.
  4. Results update instantly as you type.
  5. Use the reference table below to compare common fabric types.

Use cases

  • Estimate GSM fabric weight from a fiber denier spec before ordering.
  • Convert supplier denier data to Tex or dtex for compatibility with European standards.
  • Verify that a fabric sample's denier aligns with its stated GSM range.
  • Compare fiber fineness across nylon, polyester, and silk textile lines.
