GSM of Knitted Fabric Calculation

By using the following calculator, based on Course Per Inch, Stitch Length, and Tex, you can quickly and accurately determine the weight of knitted fabrics in grams per square meter (GSM), aiding in fabric selection, production planning, and quality control in textile manufacturing processes.

Calculate the GSM of Fabric


The result obtained from the calculator represents the weight of the knitted fabric in grams per square meter (GSM). This value indicates the fabric's thickness and density, which can affect its properties such as softness, durability, and suitability for different applications.

The variables meaning:

Course Per Inch (CPI)- represents the number of knitted stitches per inch along the width of the fabric.
Stitch Length- the length of each knitted stitch, typically measured in millimeters (mm). There is an option to switch to cm, dm, m, in, ft, and more.
Tex- a unit of linear density, representing the mass of yarn in grams per 1000 meters of length.

How the GSM is calculated:

1. Calculate the Linear Density of Yarn:

\text{Linear density (g/m)} = \frac{\text{tex}}{10}

2. Calculate the Fabric Density:
Fabric density refers to the number of yarns per unit area.

\text{Fabric Density} = \text{CPI} \times \text{Stitch Length}

3. Calculate the GSM:

\text{GSM} = \text{Fabric Density} \times \text{Linear Density (g/m)}
