In this blog, we will explain what gsm is and why it is important when selecting the perfect fabric. We will also discuss what a range of gsm fabrics are commonly used for and why they are beneficial. So stay tuned to find out more.
What Does GSM Stand For?
Simply “gsm” stands for grams per square metre. It is the metric measurement used in regard to the weight of a fabric. This measurement helps you to get an idea of what kind of fabric you are purchasing. You need to consider the usage of the fabric in accordance with the suitable weight. As a rule, it is generally thought that the heavier the weight the thicker the fabric is. It is also thought that the thicker the fabric the more long-lasting it is, for example, denim jeans last for years, whereas lighter fabric shirts require greater care, like linin. Do bear in mind that the weight does not necessarily correlate to the thickness of the fabric so do bear that in mind. And weight does not determine quality.

What To Consider When Choosing A Weight
To create the perfect garment, or find the best-matched fabric for a project, it is useful to know if the weight of fabric will align with your desired outcome. Here are a few things to consider when selecting a fabrics weight.
Weather Conditions
Lightweight fabrics are typically used for more summery and breathable items as well as intimates such as underwear. They usually have a more preferable drape, and may even require a backing fabric in order to create a more structured outcome. Thicker fabrics already provide this structure as they are normally stiffer so are a lot better at keeping their shape.
Comfort
Depending on the fabric some that are heavier in weight are seen to be a lot less comfortable. Take denim for example. Heavier denim is a lot denser so is seen to be a lot less comfortable due to its sturdy nature. However, this means that is it a lot more durable so is made to really last. As it is stiff this may cause difficulty when putting on and removing the garment, as well as a more restricted and uncomfortable movement.
Asthetics
If you want a sturdy and durable looking clothing item that keeps its shape then you need a medium to heavy weight fabric. If you want a more flowy, light and breezy look then a lightweight fabric is perfect for you. Selecting the right weight can achieve your desired look and drape and will be a lot easier to work with.
