What is GSM in Textile?
GSM stands for Grams per Square Meter. It is one of the most important measurements used in the textile and apparel industry to identify the weight of a fabric.
Higher GSM fabrics are usually thicker, heavier, and more durable, while lower GSM fabrics are lighter, softer, and more breathable. GSM measurement helps textile manufacturers maintain consistency in quality and performance.
Fabric GSM is widely used in:
- Garment manufacturing
- Fabric sourcing
- Textile exports
- Knitwear production
- Denim manufacturing
- Upholstery fabrics
- Sportswear fabrics
- Home textile products
For example, lightweight summer t-shirts may use fabrics around 120–180 GSM, while denim fabrics can range between 250–450 GSM.
What is Ounce per Square Yard (oz/yd²)?
Ounce per square yard is another standard fabric weight measurement system mainly used in the United States textile industry.
In this system, the weight of one square yard of fabric is measured in ounces. Denim, canvas, fleece, and industrial fabrics are commonly measured using ounces.
Since many countries use GSM as the standard unit, fabric buyers and exporters frequently need an oz to GSM conversion calculator for international textile trade.
Ounce to GSM Formula
The standard formula used for oz to GSM conversion is shown below.
GSM=oz/yd2×33.906GSM = oz/yd^2 \times 33.906
Example:
If a fabric weighs 6 oz/yd²:
6×33.906=203.44 GSM6 \times 33.906 = 203.44\ GSM
Therefore, a 6 oz fabric equals approximately 203 GSM.
