Normally a clothes merchandiser does no longer comply with the cloth manufacturing systems. The garb merchandiser ordered the knitting part with the aid of presenting the required guidelines (Fabric type, GSM) given by using the buyer. As a result, the merchandiser can’t supply surety about the contained cloth GSM. If merchandiser will observe some GSM calculation method, can without problems pick out the right material GSM. As its significance in clothes merchandising today, I will current the GSM calculation technique in this article.
As a garments merchandiser, everyone has to know about the GSM calculation method. GSM can be calculated by using a GSM cutter or sometimes without using a GSM cutter.

What is GSM?
GSM means gram per square meter. Its unit is (gm/m2). In knitting fabric, it is the main parameter. It is controlled by loop length. If loop length increases GSM will decrease and vice versa.
What is GSM Cutter?
GSM cutter is one kind of circular cutter, which cuts 1/100 of a square meter of fabric area.
How to Calculate GSM, Without Using GSM Cutter:
During calculating fabric GSM without using any GSM cutter, we should follow the following steps:
At first, cut 5pcs (12cm × 12cm) fabric sample from the different portion of the fabric. (Here 12cm is in length and 12cm is in width).
Measure the weight of each sample in one by one method.
Now, calculate the average weight of the fabric sample.
Also, calculate the fabric sample area by multiplying length and width.
Now by putting “average sample weight” and “fabric sample area” in the following formula, we can get easily the fabric GSM.
GSM calculation formula (in case of without using GSM cutter),
Example:
Suppose, 5pcs (12cm × 12cm) size fabric sample weights are 1.8gm, 2gm, 1.85gm, 1.90gm and 1.95gm respectively.
Now, The average weight of (12cm × 12cm) size fabric sample is, = 1.9gm
And, Sample fabric area = fabric sample length × fabric sample width = (12 × 12) = 144cm2
Now, GSM (in case of without using GSM cutter),
= 131.94
So, fabric GSM is 131.94
