Easily determine the average yarn count (Ne) of your woven fabric from its Grams per Square Meter (GSM), Ends Per Inch (EPI), Picks Per Inch (PPI), and average crimp percentage. This textile calculator simplifies complex estimations for quality control, sourcing, and fabric development. Get instant results and optimize your fabric specifications for better fabric GSM.
Formula:
Average Yarn Count (Ne) = ( (EPI + PPI) × (1 + Crimp / 100) × Material Constant ) / GSM
Where:
- GSM = Fabric Weight in Grams per Square Meter (g/m²)
- EPI = Ends Per Inch (Number of warp yarns per inch)
- PPI = Picks Per Inch (Number of weft yarns per inch)
- Crimp = Average Crimp Percentage (e.g., enter 5 for 5%)
- Material Constant = A factor specific to the fiber type (e.g., 1.50 for cotton/polyester, approximately derived from unit conversions)
