About the Thread Consumption Calculator
Estimate sewing-thread demand without turning a stitch description into a fixed factory standard.
How it works
Thread per garment equals seam length multiplied by the entered stitch factor; quantity and waste are then applied.
Example
A 12 m seam length with a factor of 2.5 requires about 30 m before waste.
Notes
Actual factors vary with stitch class, seam construction, tension and machine setup, so measure a sample when accuracy matters.
