In textiles, GSM stands for "Grams per Square Meter." It is a measurement used to determine the weight or density of a fabric. GSM represents the weight of a fabric in grams per square meter of area.
GSM is an important parameter used to describe the thickness, heaviness, and quality of fabrics. Fabrics with higher GSM values are generally denser, thicker, and have a higher weight per unit area. On the other hand, fabrics with lower GSM values are lighter and less dense.
GSM is often used as a reference point for selecting fabrics suitable for specific applications. For example, lightweight summer clothing may be made from fabrics with a lower GSM, while heavier winter coats may use fabrics with a higher GSM for better insulation.
It's important to note that GSM alone does not provide a complete understanding of a fabric's quality or performance. Other factors such as fiber content, weave, and finishing processes also contribute to the overall characteristics of the fabric. However, GSM can serve as a useful initial indicator of a fabric's weight and density.
