If you’re in the textile industry or have a discerning eye when shopping for clothing, you may have come across the term “cotton GSM” before.

GSM stands for “grams per square meter” and it is a measure of the weight and thickness of cotton fabrics.

In this blog, we will explore the concept of cotton GSM, its importance, and how it affects the quality of cotton fabrics.

What is Cotton GSM?

Cotton GSM is a measure of the weight of a cotton fabric per unit area, usually measured in grams per square meter.

The higher the GSM value, the heavier and thicker the fabric will be.

It is important to note that different fabrics can have different GSM values despite having the same weight. This is because the GSM value considers the fabric’s weave, which can affect its thickness and feel.

Is There A “Standard” GSM For T-Shirts?

The standard GSM (grams per square meter) for t-shirts can vary depending on a few factors such as the type of material used and the intended use of the shirt.

Generally, most t-shirts are made from cotton, which has a GSM range of 120-200.

However, there are also t-shirts made from polyester, which has a lower GSM range of 75-150. The reason for this difference is that polyester is a more lightweight and breathable material than cotton.

When it comes to the intended use of the t-shirt, a heavier GSM may be preferred for a more durable and long-lasting shirt, while a lighter GSM may be more comfortable for everyday wear.

It is important to note that the GSM of a t-shirt is just one factor to consider when purchasing a shirt, and other factors such as fit, style, and colour should also be taken into account.

At the end of the day, you will usually choose a t-shirt based on how you think it looks… But you will often find that cheaper t-shirts do not last as long as higher-quality, higher-GSM garments.

We’ll come back to that point at the end of this blog!

The Importance of Cotton GSM

Understanding cotton GSM is important for both manufacturers and consumers.

For manufacturers, knowing the GSM value of cotton fabrics is crucial in determining the quality and properties of the fabric. This can help them decide on the appropriate use for the fabric, such as whether it is suitable for making bed sheets or t-shirts.

For consumers, understanding cotton GSM can help them make more informed purchasing decisions. A higher GSM value generally indicates that the fabric is of higher quality, thicker, more durable, and has better moisture absorption.

Additionally, a higher GSM value can provide a softer and more comfortable feel to the fabric.

Most t-shirts will be below the 160 GSM mark. As a wearer, you will notice that some cotton t-shirts feel “thinner” and they will often be easier to tear or more prone to issues that result from repeated washing or wearing.

This is why the Big Tee Shirt range of t-shirts is all 180 GSM.

Whilst that may not mean much to read from a website, we can assure you that the instant you put the fabric on, you will notice a difference from what you are used to.

180 GSM marks the difference between comfort and durability: You want a t-shirt that is robust enough to last… wear after wear and wash after wash without being too hot for summer wearing or too thin for colder climates.

After over 20+ years in the big men’s clothing industry, we can assure you that 180 GSM is perfect.

More Factors Affecting Cotton GSM

Several factors can affect the GSM value of cotton fabrics. These include the type of cotton used, the yarn count, the weave, and the finishing process.

The type of cotton used can affect the overall quality of the fabric, which in turn can affect its GSM value. High-quality cotton, such as Egyptian or Pima cotton, typically has a higher GSM value due to its superior softness and durability.

The yarn count, or the thickness of the yarn used in the fabric, can also affect the GSM value. A higher yarn count typically results in a higher GSM value, as the fabric will be thicker and heavier.

The weave of the fabric can also affect its GSM value. Different weaves, such as plain weave, twill weave, and satin weave, can create different textures and thicknesses in the fabric.

Finally, the finishing process can affect the GSM value of the fabric. Certain finishes, such as mercerization (a process used to improve properties like the feel, strength, dye absorption and stability), can increase the weight and thickness of the fabric, resulting in a higher GSM value.

How Cotton GSM Affects Fabric Quality And Your Comfort.

Cotton GSM plays a significant role in determining the quality of cotton fabrics.

A higher GSM value can indicate that the fabric is of higher quality, as it will be thicker, more durable, and have better moisture absorption.

Additionally, a higher GSM value can provide a softer and more comfortable feel to the fabric.

A lower GSM value can indicate that the fabric is of lower quality, as it will be thinner, less durable, and have poorer moisture absorption. Fabrics with lower GSM values can also feel rougher and less comfortable to wear.
