Stitch Length Specification Targets for Buyers
Setting Stitch Length correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Stitch Length next to composition and weight so all three are quoted as one package. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: 2.6-3.4 mm typical stretch knit. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.

Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. Keeping reference values for Stitch Length lets suppliers quote without extra sampling rounds. Ask for conditioning details together with machine cam setting, since both affect the reading.
Verification method
Confirm with machine cam setting and keep the report against the bulk record. Working figures for Stitch Length normally sit around 2.6-3.4 mm typical stretch knit in mainstream production. Note machine cam setting on the tech pack so nobody tests against an older revision.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. Record elastane content alongside Stitch Length, because blends shift the measured value. A result outside 2.6-3.4 mm typical stretch knit usually points to process drift rather than to the fibre itself.
