Understanding Fabric GSM: A Complete Guide to Choosing the Right Fabric Weight
Meta Description:
Learn what fabric GSM (grams per square meter) means, how it affects your clothing, and how to choose the best GSM for different apparel types. Essential for fashion brands and custom clothing manufacturers.
What Is Fabric GSM and Why Does It Matter?
GSM (Grams per Square Meter) is a critical specification in the textile industry. It refers to the weight of fabric measured per square meter. The higher the GSM, the heavier and usually thicker the fabric. Understanding GSM is essential in determining a fabric’s suitability for different types of garments, from lightweight summer shirts to heavy winter hoodies.
How GSM Affects Clothing Quality and Usage
| GSM Range | Fabric Weight | Common Uses |
|---|---|---|
| 100–150 GSM | Lightweight | T-shirts, summer dresses, linings |
| 160–200 GSM | Medium weight | Polo shirts, basic sweatshirts |
| 200–300 GSM | Heavyweight | Hoodies, joggers, heavier T-shirts |
| 300+ GSM | Extra Heavy | Winter outerwear, fleece hoodies |
Higher GSM fabrics tend to be:
-
More durable
-
Less transparent
-
Better suited for colder climates
Lower GSM fabrics are:
-
More breathable
-
Lighter and flowy
-
Ideal for warm weather wear
Choosing the Right GSM for Your Product Line
When selecting fabric for your clothing brand or custom order, consider:
-
Seasonality: Use lighter GSM for spring/summer, heavier for fall/winter.
-
Style Intent: A luxury feel might demand heavier, more structured fabric.
-
Durability Needs: For activewear or uniforms, a GSM of 180+ ensures longevity.
GSM vs Thread Count – Know the Difference
While GSM measures fabric weight, thread count refers to the number of threads per inch in woven fabrics (common in bedsheets). Both affect texture and quality but are not interchangeable.
