What is GSM in Fabric?｜Understanding Fabric Weight and Its Importance
When shopping for clothes, you may have come across the term GSM
(grams per square meter) in fabric descriptions. But what does it actually
mean? What is GSM in Fabric? Many people mistakenly believe that higher GSM always means better quality, but that’s not necessarily true. In this article, we’ll break down what GSM is, why it matters, and how it affects the breathability and
comfort of your clothing.
What Does GSM in Fabric Mean?
GSM refers to the weight of fabric per square meter. The higher the GSM,
the heavier and thicker the fabric. However, this doesn’t always translate to
better quality. In fact, excessively high GSM fabrics can feel bulky and
uncomfortable, while lower GSM fabrics can offer cool material to wear,
especially in warm weather.
Fabric GSM and Seasonal Suitability
Understanding GSM helps you choose the right fabric for different seasons:
160-200 GSM: Perfect for summer. Lightweight, breathable, and ideal for
GSM, striking the perfect balance between softness and durability.
220-350 GSM: Versatile for both summer and autumn. Slightly thicker but still
comfortable.
350-500 GSM: Suitable for cold seasons. Heavy fabrics like hoodies and
sweatshirts fall into this category.
While high GSM fabrics may seem premium, they often come with drawbacks.
A 500 GSM hoodie can feel like carrying a 2kg weight throughout the day,
making it impractical for casual wear.
Is Higher GSM Always Better?
Not necessarily. Just like gold and brass have different values despite their
weight, fabric quality depends on materials, weaving techniques, and finishing processes rather than GSM alone. Many high-tech, lightweight
fabrics require millions of dollars in research and development to achieve
high durability, breathability, and cooling properties.
Common GSM References for Clothing
To help you better understand fabric weights, here are some typical GSM
values:
130 GSM – Lightweight sports vests
260 GSM – Heavyweight T-shirts
360 GSM – Autumn sweatshirts
420 GSM – Winter sweatshirts
