Understand what GSM can and cannot tell you

GSM describes fabric weight, but two fabrics with the same GSM can feel different because of yarn, knitting, finishing, and composition.

180-220 GSM can work for premium everyday tees
220-280 GSM supports heavier streetwear tees
Finish and wash change handfeel

Match GSM to fit and neckline

Oversized T-shirts need enough structure, but the neck rib must also recover after wear and wash. Heavy body fabric with weak rib can make the product feel cheap.

Confirm shoulder width and sleeve opening
Check neck rib stretch and recovery
Review shrinkage before bulk

Plan print method with fabric weight

Screen print, puff print, discharge effects, and heat transfer all behave differently on heavyweight jersey. Test the actual fabric route before bulk.
