GSM (Grams per Square Meter)
GSM measures fabric weight per unit area, expressed in grams per square meter. It's the primary metric for classifying fabric density.
GSM (Grams per Square Meter) is the standard measure of fabric weight used throughout the textile industry. It quantifies how much a one-square-meter piece of fabric weighs in grams.
GSM determines fabric thickness, density, and intended use. Lightweight fabrics (100-150 GSM) suit summer apparel and linings. Medium-weight fabrics (180-250 GSM) are used for t-shirts and general apparel. Heavy fabrics (300+ GSM) are used for denim, upholstery, and technical textiles.
In ERP systems, GSM is stored as an attribute on every fabric SKU and every roll. It's used for costing calculations (fabric cost per kg × GSM × area), inspection thresholds (4-point system uses GSM-adjusted scoring), and specification matching when fulfilling orders.
TextileERP natively supports GSM tracking at the roll level, with automatic GSM-based costing, allocation, and quality grading workflows.

4-Point Inspection System
The 4-point system grades fabric quality by assigning penalty points for defects based on length and severity. It's the textile industry's standard quality method.
Fabric Roll
A fabric roll is the standard shipping unit for textile fabric, typically 50-150 meters. Each roll has unique attributes: dye lot, shade, GSM, width.
