GSM stands for grams per square meter and is a metric used to measure the density of the fabric. The higher the GSM number, the denser the fabric. Fabric with a high GSM is typically heavier and more durable, while fabric with a low GSM is usually lighter and more delicate.
For instance, a linen shirt with a label of 180-200 GSM would be made of thick material that would keep the wearer warm. When choosing a shirt for warmer days, go for one that is 100-150 GSM. This type of shirt is airy and flimsy, making it the ideal choice for hot weather. This rule applies to all types of towels, upholstery linen and clothing, from winter to summer wear. Therefore, when considering the value of a fabric's GSM, think about what the fabric will be used for.
Why Do You Need To Measure Fabric Weight?
