Understanding GSM: What Fabric Weight Really Means

GSM (Grams per Square Meter) measures the weight of fabric per square meter. This simple number can tell you a lot about how thick, soft, and durable a fabric is.

• Lightweight Fabrics (100–150 GSM): Soft, breathable, ideal for summer tops and t-shirts.
• Medium-weight Fabrics (150–200 GSM): Balanced durability and comfort; common in sweatshirts and casual tees.
• Heavyweight Fabrics (200+ GSM): Thick, warm, and long-lasting; perfect for hoodies and jackets.

Why GSM Matters:

• Determines comfort and breathability.
• Impacts durability—heavier fabrics generally last longer.
• Affects drape and structure; lightweight fabrics flow, heavyweight fabrics hold their shape.

Example: A 120 GSM t-shirt feels light and airy, perfect for hot weather. A 220 GSM hoodie provides warmth and durability.
