When people say a T-shirt feels “thin” or “premium,” they’re often talking about GSM – but few know what it actually means.
🔍 What is GSM?
GSM = Grams per Square Meter
It tells you the weight and thickness of fabric. Higher GSM means heavier, thicker fabric. Lower GSM = lighter and more breathable.
| GSM Range | Fabric Weight | Application |
|---|---|---|
| 130–160 | Lightweight | Summerwear, innerwear |
| 180–200 | Medium | Basic tees, merch |
| 220–260 | Heavyweight | Premium streetwear, boxy fit |
| 300–400+ | Very Heavy | Hoodies, sweatshirts |
💡 Why GSM matters
-
Fit & Structure: High GSM fabric helps tees hold shape, especially for oversized or boxy fits.
-
Durability: Heavier fabric usually lasts longer and resists wear.
-
Customer Perception: GSM contributes to how “premium” your product feels.
