How to Find GSM of Fabric with and without GSM Cutter
Last updated: Oct 11, 2020
GSM is the short form of Grams per Square Meter. Fabric GSM is used in the RMG sector to compare fabrics in an unit area. A simple understanding of fabric GSM is that if we cut a piece of fabric in an area of 1 square meter & weight it, the respected value of that weighting will be the fabric GSM of that fabric. GSM is calculated in metric measurement unit.
Normally there are two methods of calculating fabric GSM. Which are –
In this article, we’ll take a look at how to find GSM of fabric without fabric cutter and how to do GSM calculation with GSM cutter.
To determine fabric GSM without GSM cutter we need the following apparatus.
The standard atmosphere for testing should be maintained, because moisture content may change the weighting of the sample and jeopardize the result. So the temperature should be near 20°c ± 2°c and humidity Should be near 65% ± 2%.
To determine fabric GSM with GSM cutter we need the following apparatus.

The standard atmosphere for testing should be maintained, because moisture content may change the weighting of the sample and jeopardize the result .so temperature should be near 20°c ± 2°c and humidity should be near 65% ± 2%.
|With GSM Cutter||Without GSM Cutter|
|Sample no||Weight(gm)||GSM=Weight X 100||Average GSM||sample no||Weight(gm)||GSM=Weight X 100||Average GSM|
Fabric GSM= Weight of the sample in grams X 100
Fabric GSM=1.56 X 100
Fabric GSM=156 gm
This is how other calculations are done too.
These methods are widely used in testing laboratories and industries. Relaxation and testing atmosphere is a must parameter to be maintained or else testing results will not be accurate. The instruments used are sure to be calibrated properly.
You probably still have some queries. Check the following Q&A section to find your answers.
GSM cutters pod is circular and we get circular sample. The sample we get is in cm form. The GSM cutter pod dia is 11.28cm
So we know, Area = Πr² = Π(D/2)²
=3.14 x (11.8/2)2
=100 Square cm
Now, 1 meter = 100cm
And, 1 square meter = 100 cm x 100 cm
To convert the centimeter value to meter value it is multiplied with 100.
Hopefully, after reading this article, you’ve got the answers to how to find GSM of fabric without fabric cutter.
