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
- Enter the denier value and thread count per cm² into the input fields.
- GSM is calculated as (Denier × thread count per cm²) / 9.
- Tex is derived as Denier / 9; dtex is Denier × 10 / 9.
- Results update instantly as you type.
- 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.
