GSM Formula:
From: | To: |
GSM (Grams per Square Meter) is a metric measurement of the weight of fabric. It represents the weight of one square meter of fabric in grams. GSM is an important specification for woven fabrics that helps determine quality, thickness, and appropriate uses.
The calculator uses the GSM formula:
Where:
Explanation: The formula calculates the weight per unit area by relating the total weight to the total length (assuming standard fabric width).
Details: GSM is crucial for fabric quality control, pricing, and determining appropriate applications. Higher GSM indicates heavier, more durable fabric while lower GSM indicates lighter, more breathable fabric.
Tips: Enter the weight of your fabric sample in grams and its length in meters. Ensure accurate measurements for precise GSM calculation.
Q1: What is a good GSM range for woven fabrics?
A: Common ranges are 100-150 GSM for light fabrics, 150-300 GSM for medium weight, and 300+ GSM for heavy fabrics.
Q2: How does GSM relate to fabric thickness?
A: Generally, higher GSM indicates thicker fabric, but the relationship depends on fiber type and weave density.
Q3: Should I measure GSM with a standard sample size?
A: While any size can be used, standard practice is to measure a 10cm × 10cm sample for better accuracy.
Q4: Does GSM affect fabric drape?
A: Yes, lower GSM fabrics typically drape more fluidly while higher GSM fabrics are more structured.
Q5: Can I use this calculator for knitted fabrics?
A: This formula works for woven fabrics. Knitted fabrics may require different measurement techniques due to their stretch.
