Relation between Finished GSM and Yarn Count of Various Fabrics

Introduction:
‘GSM’ means ‘Gram per square meter’ that is the weight of fabric in gram per one square meter. It is one kind of specification of fabric. The count is the coarseness or fineness of the yarn. There are important relationships between yarn count and GSM in knitted fabric. In this article, there is some relations are given for different fabrics. In this article, we will know about the relationship between finished GSM and yarn count of various fabrics.

Fabric GSM: GSM means Gram per Square Meter. That means the weight of fabric in grams per square meter. Which unit is (gm/m²).

Yarn Count: The count is a numerical value, which expresses the coarseness or fineness of the yarn and also indicates the relationship between length and weight (the mass per unit length or the length per unit mass) of that yarn. It is very important to know the yarn count, especially in knitting.
