Industrial Textile Glossary
Standardized definitions, testing nomenclature, and manufacturing terminology recognized across circular knitting mills and weaving plants.
G
GSM
Grams per Square Meter (g/m²); the international standard metric measurement for fabric areal weight.
GSM measures the weight of one square meter of fabric in grams. It establishes a standardized comparison metric regardless of fabric width. Standard textile testing involves cutting a circular specimen (usually 100 cm² with a circular GSM cutter) and weighing it on a precision electronic balance.
Industrial Application: A lightweight summer t-shirt typically utilizes 140-160 GSM single jersey, whereas heavy French Terry hoodies use 320-400 GSM.
