GSM is an important parameter for the evaluation of Fabrics and textiles. In this blog post, we will explore the concept of GSM and show you an easy way to calculate it yourself. We’ll also look at why GSM is an important factor to consider when manufacturing or purchasing fabrics and textiles. Read on to learn more about calculating GSM and its importance in the world of fashion design!
GSM or grams per square meter is a metric measurement used to determine the density of a fabric. To calculate GSM, all you need is a scale and a ruler. Find out the dimensions of a square meter then weigh the material in grams to get its GSM.
For example, let’s say we have a piece of fabric that is 1 meter by 1 meter. Weighing this fabric would give us its GSM. If the fabric weighs 80 grams, then its GSM would be 80 g/m2.
No matter the size of the material, whether big or small, as long as you know its dimensions and weight, you can calculate its GSM!
To calculate the GSM of a material, you will need to know the basis weight of the material and the density of the fibers used to create the fabric. The basis weight is measured in ounces per yard (oz/yd) or grams per square meter (g/m^2).
The exact size of sample can be obtained using a GSM Cutter.
To find the GSM, simply divide the basis weight by the density of the fiber. For example, if you have a material that has a basis weight of 8 oz/yd and a density of 1.5 g/m^3, then the GSM would be 5.33 oz/yd or 186 g/m^2.
Keep in mind that the GSM will vary depending on how tightly woven the fabric is. A loosely woven fabric will have a lower GSM than a tightly woven fabric.
GSM is an important metric for characterizing the properties of materials. It stands for grams per square meter, and it is a measure of the density of a material. The higher the GSM number, the denser the material.
GSM is important because it gives us a way to compare different materials on a common scale. For example, if we want to compare the density of two fabrics, we can simply look at their GSM numbers.
GSM can also be used to predict other properties of materials, such as thickness, stiffness, and absorbency. In general, the denser the material, the thicker it will be. And stiffer and more absorbent materials will also have higher GSMs.
So, if you need to know how dense a material is, or how thick or stiff or absorbent it might be, looking at its GSM is a good place to start.
There are a few benefits of knowing the GSM of your fabric.
For one, it can help you determine the right thread count for your project. If you're working with a thinner fabric, you'll want to use a finer thread. Conversely, if you're working with a thicker fabric, you'll want to use a heavier thread.
Additionally, the GSM can also affect the overall drape of your garment. Thinner fabrics will often have a more fluid drape, while thicker fabrics will be more structured.
Knowing the GSM can help you choose the right fabric for your desired look and feel.
To calculate the GSM of a material, you will need to know the basis weight and density of the material. The basis weight is the weight of a ream (500 sheets) of paper in its basic unit uncut size, which is typically given in pounds. To find the density, divide the basis weight by the ream's uncut size in inches.
For example, if 500 sheets weigh 20 pounds and have an uncut size of 39 inches by 54 inches, then the density would be 0.5 pounds per square inch (20 divided by 39). To calculate GSM, multiply the density by 1,000. In our example above, that would give us a GSM of 500 (0.5 multiplied by 1,000).
Calculating GSM of materials is an important parameter that needs to be kept in mind when it comes to maintaining quality standards and one that can help you manufacture international quality garments. With our simple explanation, we hope that understanding the concept behind this measurement has now been made easier for you.

FAQs
GSM in fabrics is known as Grams per Square meter. GSM is a unit of measurement used to measure the weight or density of a given fabric. It shows how much 1 square meter of fabric weighs. GSM also provides details of the fabric’s thickness and durability. GSM of fabrics can be divided into 2 categories:
GSM helps manufacturers and consumers to calculate a fabric’s weight, feel, and suitability for a specific purpose.
GSM is the metric to determine the properties of a given fabric. It is Gram per Square Meter used to measure the density of a given fabric. The higher the GSM number, the higher the density of Fabric. Calculating the GSM of fabric is important due to several reasons:
GSM stands for “Grams per Square Meter” and is a standard unit to measure the weight of fabric. It determines how heavy a particular fabric is in a perticular area. The formula for GSM of fabric is
GSM = (Weight of fabric in grams) / (Area of fabric in square meters)
To determine the GSM of a fabric, you first need to weigh a sample of the same fabric in grams. Then, you measure the area of that fabric sample in square meters. Then divide the weight of the fabric (in grams) by its area (in square meters). This calculation gives you the GSM of the fabric.
For example, if a fabric sample weighing 10 grams has an area of 0.01 square meters, its GSM would be 1000 (10 grams / 0.01 square meters).
Calculating the area of a fabric is easy. First to calculate the area of a fabric you need to determine these points:
To calculate area of a fabric you need to multiply both length and width of the fabric in the same unit. This formula gives you the area of fabric:
Area = Length x Width
GSM of fabric can be calculated easily by dividing the weight of fabric by area of fabric.
Gran per Square Meter is the unit of measurement Which provide the density of fabric in GSM value.
To calculate GSM of fabric, you need to take 4 - 5 samples of the same fabric and weigh them precisely with a weighing scale. Once you get the perfect measurement of the weight of fabric you need to calculate the area of fabric in square meters. Once you get both values for your fabric divide them together to calculate the GSM value of fabric. The formula for GSM value is (Weight of fabric in grams) / (Area of fabric in square meters).
First, you need to get the sample of the fabric you need GSM value for. Calculate the weight (in grams) and area (in square meters) of the sample. Divide both the weight and area together to get the GSM value. To calculate the GSM of knitted fabric you need to follow these steps:
Getting GSM of any fabric can be beneficial in several ways. GSM helps to determine the sustainability of fabric. High GSM value fabrics are used for heavy-duty purposes such as winter clothes, car seats, and industrial purposes. While low GSM value fabrics are used to make lightwear clothes. GSM gives you the potential performance of a fabric.
By GSM of fabric manufacturers and industries can evaluate the production cost of the materials and optimize the fabric. Reduce material waste in production procedures. It also helps to maintain product quality across the whole production to reduce damaged products.
GSM impacts the design and appeal of fabric. Designers use GSM to get the details of fabric for their designs so that they fulfill their requirements for fashion design.
To find the GSM of fabric you need to evaluate the weight in grams and area of fabric in square meters. Then, divide both weight and area of fabric to find GSM of fabric. Here is how you can find the GSM of fabric:
The GSM calculator is a tool that automatically calculates the GSM value of a fabric. Many websites offeres online GSM calculator. Here’s how GSM calculator for fabric works:
In the calculator, put the values of your fabric, weight, and area (put length and width the calculator will automatically calculate the area of fabric). Enter these values correctly for a perfect GSM value of fabric. The calculator will show you the GSM of fabric.
