When shopping for fabric, you may have come across the term “GSM” and wondered what it means. GSM stands for grams per square meter, and it is used to measure the weight and density of fabrics. Understanding GSM can help you choose the right fabric for your project and ensure you get the desired look and feel.
What is GSM?
GSM is a measurement of the weight and density of a fabric. It is calculated by weighing a square meter of fabric and then dividing the weight by the area. The higher the GSM, the thicker and more dense the fabric. A lower GSM indicates a lighter and thinner fabric.
What is the importance of GSM?
GSM is important because it can affect the look, feel, and durability of a fabric. A heavier fabric with a higher GSM may be more durable and offer better insulation, but it may also be less breathable and less comfortable to wear. A lighter fabric with a lower GSM may be more comfortable and breathable, but it may not be as durable or insulating.
How is GSM used in fabric?
GSM is used to describe the weight and density of various types of fabric, including cotton, wool, silk, and synthetic materials. It is often used in the production of clothing, bedding, and other textiles. Fabric with a higher GSM is typically used for heavier garments and home decor items, while fabric with a lower GSM is used for lighter weight and more breathable garments.
How can you determine the GSM of a fabric?
The GSM of a fabric can be determined by weighing a square meter of the fabric and then dividing the weight by the area. Alternatively, you can use a GSM meter, which is a handheld device that measures the weight and density of fabric.
What are some common GSM ranges for fabric?
The GSM range for fabric can vary widely depending on the type of fabric and its intended use. However, some common GSM ranges include:
Lightweight fabrics:
– Cotton voile: 70-80 GSM
– Chiffon: 50-70 GSM
– Organza: 20-50 GSM
Medium weight fabrics:
– Cotton poplin: 130-150 GSM
– Linen: 150-190 GSM
– Flannel: 160-200 GSM
Heavyweight fabrics:
– Denim: 250-400 GSM
– Wool melton: 500-900 GSM
– Upholstery fabric: 300-600 GSM

Can the GSM of a fabric be altered?
The GSM of a fabric cannot be altered once it has been woven. However, the thickness and density of a fabric can be adjusted during the weaving process.
What is the difference between GSM and oz/yd²?
GSM is a metric measurement that calculates the weight of a fabric in grams per square meter, while oz/yd² is an imperial measurement that calculates the weight of a fabric in ounces per square yard.
What is the ideal GSM for a t-shirt?
