What GSM means
GSM is a useful way to describe fabric weight. In a production brief, it should sit alongside fabric composition, finish, stretch and intended use rather than being treated as the only quality signal.
What to send a manufacturer
Share the article or reference, intended use, preferred hand-feel, colour direction, size run and any existing sample. If GSM is critical, ask the production team to confirm the target before bulk cutting.
Why consistency matters
For repeat B2B orders, a clearly documented fabric specification helps reduce variation between runs and makes future reorders easier to manage.
