GSM means the weight in gram per square meter of fabric. GSM is a very important parameter for specified a certain quality of knitted fabric. The production of knitted fabric is calculated in weight. Fabric GSM calculation is a physical test. This test is done by GSM Cutter. GSM cutters are used to determine accurately the GSM (Grams per square meter) of any type of fabrics. It is very popular and easy usable GSM testing instrument used in most knitted factory.

How to Calculate Fabric GSM by GSM Cutter:
Now I will give procedure of fabric GSM calculation step by step,

  1. Cut the fabric with the GSM cutter (gram per square inch).
  2. Weight the fabric with the electric balance.
  3. The cut sample is 100 The weight of the cut sample is multiplied by 100.
  4. The result is the GSM of that particular fabric.
For accuracy test with multiple (e.g. 5 samples) samples and calculate average GSM.


Let, sample weight 1.5 gm

In this situation, we have to multiply average cutting swatch weight by 100 to get actual fabric GSM.


Fabric GSM = Average cutting swatch weight × 100
= 1.5 × 100
= 150

So, fabric GSM by using GSM cutter is 150
