What does GSM mean in fabric?

GSM stands for Grams per Square Meter. It is the metric measurement of the weight of a fabric. A higher GSM indicates a denser, thicker, and generally more durable fabric.

How do you calculate total fabric weight?

To calculate total fabric weight, convert the length and width of the fabric into meters, multiply them to get the total square area, and then multiply that area by the fabric's GSM.
