How to Find Fabric GSM without Using GSM Cutter?

Would you like to learn how to calculate fabric GSM without using the GSM cutter? Read this post.
Fabric GSM

You might know that GSM stands for grams per square meter. Fabric GSM is used to represent the fabric weight and thickness of the fabric, which is an essential fabric quality parameter. In the earlier posts, I have discussed the method of calculating fabric GSM using the testing instruments (GSM cutter and weighing balance) and yarn count and fabric construction details.

In this post, I have shared Do it Yourself (DIY) guide to finding fabric gsm without using the GSM cutter device. Follow the below steps.
  1. Cut a fabric sample of 10 cmX10 cm 
  2. Measure the weight of that specimen (sample) in grams. Here you got fabric weight per 100 square-centimeter. 
  3. Convert fabric weight into grams per square meter. To calculate it multiply above weight by 100. This will be GSM of the fabric. 
  4. For accuracy test with multiple (e.g. 5 samples) samples and calculate average GSM. 
Fabric specimen

An example:

The weight of the 5 specimens are as following:

Specimen-1: Weight - 1.65 grams
Specimen-2: Weight - 1.60 grams
Specimen-3: Weight - 1.55 grams
Specimen-4: Weight - 1.62 grams
Specimen-5: Weight - 1.58 grams
--------------------------------------------------
          Total weight = 8.00 grams
The average weight of the specimen is 1.600 grams per 100 square centimeters.
Now convert the weight into grams per square meters by multiplying the average weight by 100.

Therefore, sample fabric GSM is 1.60 X 100 = 160 GSM.

Note: You can cut another dimension than mentioned in step-1 for the specimen. You need to convert the measured weight into per square meter to get the correct fabric gsm.

GSM cutter is a circular cutter which cuts 1/100 of a square meter of fabric area.
