What Does GSM Stand For?

GSM stands for Grams per Square Meter (g/m²). It is the universal scientific unit used worldwide to measure the density, weight, and thickness of woven and knitted fabrics.

A piece of fabric measuring exactly 1 meter by 1 meter is weighed on a precision digital scale. If that square meter weighs 240 grams, the fabric has a GSM of 240.

Why Modern Streetwear Demands 220–260 GSM

In 2026, Indian D2C streetwear brands (such as oversized tees and boxy silhouettes) shifted overwhelmingly from standard 180 GSM cotton to 220–260 GSM single jersey.

  • Structured Boxy Silhouette: Lightweight fabrics collapse against the body, whereas 240 GSM holds its drop-shoulder shape without clinging.
  • Zero Transparency: Even in pure white or off-white shades, 240 GSM is 100% opaque.
  • Higher Print Durability: Heavy cotton accommodates thick Plastisol, Puff, and High-Density 3D screen prints without puckering or tearing.
