Fabric GSM (Grams per Square Meter) is a measurement of the weight of a fabric per unit area. It is an important factor in determining the quality and performance of a fabric. The higher the GSM, the denser and heavier the fabric, while a lower GSM indicates a lighter and more breathable fabric.

To calculate the GSM of a fabric, you will need a sample of the fabric and a scale that measures in grams. Here are the steps to follow:

Cut a sample of the fabric that is at least 10 cm x 10 cm in size.

Weigh the sample on the scale and record the weight in grams.

Measure the length and width of the sample in centimeters and multiply the two numbers to get the area in square centimeters.

Divide the weight of the sample by the area in square centimeters to get the GSM of the fabric.

For example, if you have a fabric sample that weighs 50 grams and measures 20 cm x 20 cm, the area of the sample is 400 square centimeters. To find the GSM, you would divide 50 by 400, which equals 0.125. Therefore, the GSM of the fabric is 125.

Understanding fabric GSM is important for choosing the right fabric for your project or application. A fabric with a higher GSM will be more durable and suitable for heavy-duty applications, while a fabric with a lower GSM will be more lightweight and breathable, making it ideal for clothing and other applications where comfort is a priority.
