What Is GSM? The Complete Fabric Weight Guide for Cotton Clothing

When buying a cotton T-shirt, hoodie, sweatshirt, or polo, you've probably noticed numbers like 180 GSM, 240 GSM, or 320 GSM in the product description.

But what does GSM actually mean?

Does a higher GSM always mean better quality?

How do you know which GSM is right for you?

In this guide, we'll explain everything you need to know about GSM and how it affects the comfort, durability, and feel of cotton clothing.

What Does GSM Mean?

GSM stands for Grams per Square Meter.

It measures the weight of one square meter of fabric.

Think of GSM as a way to describe how light or heavy a fabric is—not necessarily how good it is.

Two fabrics can have the same GSM but feel different depending on:

• Cotton quality
• Yarn type
• Knit structure
• Finishing processes
• Fabric construction

Why Does GSM Matter?

Fabric weight affects:

• Comfort
• Structure
• Warmth
• Durability
• Drape
• Overall feel

Choosing the right GSM depends on how and where you plan to wear the garment.
