One of the key understandings in the sewing world is, “What is GSM in fabrics?” What does it mean? Should you care? Is it important?

In this blog post, we will help you understand how GSM is crucial in exploring the intricacies of fabric weight and characteristics, making sure you take the right decisions when it comes to selecting fabrics for various applications and achieving the desired quality in your sewing projects!

 

What is GSM in Fabrics?

 

GSM stands for Grams per Square Meter and it is a metric used to measure the weight of fabrics.

It represents the mass of the fabric per unit area.

For example, a fabric with a GSM of 200 means that a one-square-meter piece of that fabric weighs 200 grams.

 

 

Why Should You Care?

 

Quality

 

Understanding GSM is essential for evaluating fabric quality.

It is commonly used as an indicator of fabric weight, enabling you to assess the material’s overall density and composition.

The higher the GSM, the more substantial and long-lasting the fabric is, often associated with higher quality.

 

Durability

 

GSM and fabric durability are directly related, and here is why:

A fabric with a higher GSM is inherently thicker, which means it has an increased density and weight.

This thickness contributes to the fabric’s resilience, enhancing its ability to withstand wear and tear and ultimately extending its longevity.

 

Suitability

 

Different projects require different fabrics.

Knowing the GSM of a fabric guarantees that the materials you choose are appropriate for the intended use, whether you are choosing fabrics for indoor clothing, outdoor adventures, home decor or even craft projects

For example, a lower GSM is perfect for summer clothing that is lightweight, while a higher GSM might be suitable for winter clothing that offers warmth.

 

Aesthetics

 

The GSM of a fabric can significantly influence its appearance.

Fabrics with higher GSM tend to convey a more formal and structured aesthetic, making them well-suited for upholstery or fitted dresses.

On the other hand, lower GSM adds to a more carefree and informal style, ideal for creating flowy dresses and home decor.

 

Manufacturer’s Standard

 

GSM is a standard measurement that manufacturers use to ensure quality control and consistency throughout the production process.

For example, when producing waterproof fabrics, manufacturers set specific GSM standards to ensure each material possesses the required weight and characteristics, waterproofness, thickness and breathability.
