sci.fabric-cover-factor Calculator
Calculates woven fabric cover factor from warp and weft thread count and yarn diameter, quantifying the fraction of fabric area covered by yarns. Shirting fabrics have cover factor ≈ 0.7–0.85 — denim: 0.9–0.95; lightweight muslin: 0.5–0.65.
Inputs
Warp Threads Per Cm
