Fabric GSM Calculator - Calculate Grams Per Square Meter

Calculate fabric GSM (Grams per Square Meter) quickly and accurately with our free online fabric GSM calculator. This essential tool helps textile manufacturers, garment designers, and quality controllers determine fabric weight precisely for production planning and quality control.

GSM is the universal standard for measuring fabric weight in the textile industry. It indicates how much one square meter of fabric weighs in grams. Higher GSM values represent heavier, thicker fabrics, while lower GSM indicates lighter materials. Understanding fabric GSM is crucial for cost estimation, quality assurance, and meeting buyer specifications.

How to Calculate Fabric GSM

Simply enter your fabric sample weight (in grams, kilograms, pounds, or ounces) and dimensions (in centimeters, inches, or meters). Our calculator automatically converts all units and provides instant GSM results using the formula: GSM = Weight (g) ÷ Area (m²)
