Knit Fabric GSM Calculator

Predict single jersey GSM from courses, wales, stitch length and yarn count before knitting a swatch.

Fabric GSM

105.8g/m2

Weight

3.12oz/yd2

Yarn Tex

19.68

The formula

GSM = courses/cm x wales/cm x stitch length (mm) x Tex / 100, with Tex = 590.5 / Ne.

Worked example

Courses per cm: 16, Wales per cm: 12, Stitch length: 2.8 mm, Yarn count: 30 Ne. Result: Fabric GSM = 105.8 g/m2; Weight = 3.12 oz/yd2; Yarn Tex = 19.68.

Assumptions

  • Loop-geometry relation for weft knits in the finished relaxed state entered.
  • Enter finished courses/wales; greige values predict greige GSM.

This calculator is the single-use version of what Intelactory runs across every style.

Costing sheets, line plans, dye recipes and packing lists that compute themselves from your real orders, with the numbers connected end to end.
