What GSM describes
GSM means grams per square meter and describes the mass of fabric over a defined area. It is one useful specification when discussing fabric, alongside composition, construction, thickness, finish and feel. A higher number alone does not prove better quality or suitability for a garment.
Specify composition and intended use
State the fibers or blend you want the team to review and describe the intended garment use. Include any stretch, care, appearance or specialist performance requirement. Confirm availability and suitability rather than assuming a material automatically meets those requirements.
Use references and samples
A physical swatch or clear reference can help explain the material feel and drape you want. Pair it with your composition and GSM requirements. Ask how the proposed fabric will be sampled and reviewed, and agree any testing or acceptance requirements before ordering.
