GSM stands for “grams per square meter,” and it is a unit of measurement used to determine the weight or density of a fabric. GSM is commonly used in the textile industry to describe the thickness and quality of different fabrics, including those used in garments, upholstery, and other applications.
When it comes to fabrics, GSM refers to the weight of the fabric per unit area. It indicates how many grams a fabric weighs per square meter of area. A higher GSM value generally indicates a denser and heavier fabric, while a lower GSM value suggests a lighter and thinner fabric.
The GSM of a fabric can affect its properties, such as durability, breathability, and overall feel. Fabrics with a higher GSM are typically more robust, thicker, and warmer. They are suitable for applications where strength and insulation are important, such as heavy-duty workwear, winter clothing, or upholstery fabrics.
On the other hand, fabrics with a lower GSM are lighter, thinner, and more breathable. They are commonly used for lightweight clothing, summer garments, and drapery fabrics. Lower GSM fabrics tend to be more flexible and comfortable to wear in warmer weather.
When selecting fabric for a particular purpose, understanding the GSM can be helpful in determining the appropriate fabric weight and thickness. However, it’s important to note that the GSM is just one factor to consider, and other properties like fiber type, weave, and finish also play a significant role in determining a fabric’s characteristics.
