GSM stands for “Grams per Square Meter.” It is a measurement used to indicate the weight and density of the fabric used in a T-shirt.
In simple terms, higher GSM generally means a heavier and denser fabric, while lower GSM usually means a lighter and more breathable fabric.
Example GSM Fabric Feel Best For 140–160 GSM Lightweight Summer, casual wear 170–190 GSM Medium & comfortable Regular T-shirts 200–240 GSM Heavy & premium Oversized T-shirts, premium wear 280–350+ GSM Very heavyweight Hoodies, premium streetwear
Does Higher GSM Mean Better Quality?
Not necessarily.
A 240 GSM T-shirt isn't automatically better than a 180 GSM T-shirt. Quality also depends on:
Fabric composition Yarn quality Knitting quality Bio-wash/finishing Stitching Shrinkage control Color fastness
For example, 180 GSM 100% cotton can be an excellent choice for everyday T-shirts, while 240 GSM cotton can be better when you want a heavier, premium feel.
