Stitch Length Calculator

Loop length to set on the machine for a target single jersey GSM at known courses, wales and yarn count.

Stitch length

2.8mm

Yarn Tex

19.68

The formula

SL (mm) = GSM x 100 / (courses/cm x wales/cm x Tex). The exact inverse of the knit GSM relation.

Worked example

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

Assumptions

  • Finished relaxed state; the same loop-geometry relation as the Knit Fabric GSM calculator, inverted.

In the platform

Intelactory records which yarn lot went into which fabric roll, dye batch and carton as the work happens, so a count or GSM question traces back to its source.
