What is Fabric GSM?

GSM stands for “Gram per Square Meter.” Therefore, we can say it’s a measure of fabric density, i.e., the weight of the fabric per square meter. By evaluating the fabric GSM value, we can assess whether the fabric is heavy or lightweight. The higher the GSM, the heavier it weighs and vice versa. It’s an essential parameter in the textile sector for obvious reasons. We can’t characterize a fabric without mentioning it. We can measure GSM for all types of fabrics. It’s an essential parameter of the garments ordering process. Thus, maintaining it in all stages of the production is of utmost importance. For this, every textile engineer, specially merchandiser of woven and knit garments, should know the GSM calculation to execute the order properly. Now, we must remember that while fabric GSM gives us the idea of its weight it’s not a clear indicator of its thickness. The fabric thickness mainly depends on its structure/ construction,which means that the same GSM value can be made into different thicknesses due to different structures.
