GSM, usable width, and tolerance should be written as measurable buyer requirements. A fabric name or reference image does not define the measurement point, condition, or acceptance limit by itself.
Define each measurement
| Field | What to state |
|---|---|
| Finished GSM | Target weight, permitted tolerance, sample or bulk stage, conditioning method if relevant, and the test method used for approval. |
| Usable width | The width required for cutting, how it is measured, whether selvedge or edge allowance is included, and the permitted tolerance. |
| Construction state | Whether the fabric is open or tubular, relaxed or otherwise conditioned, and any construction detail that affects comparison. |
| Dimensional checks | For shrinkage or other dimensional behavior, give the method, treatment, direction, condition, and buyer acceptance limit. |
Avoid ambiguous tolerance language
Write the numeric target and permitted range in the specification rather than using terms such as standard, stable, or within normal tolerance. When a tolerance is still open, mark it as a decision for buyer and development review.
Apply these measurement questions to the Single Jersey, Rib Knit, and French Terry categories, then use the application guides to add garment context.
