Understanding GSM in Knitted Fabrics: The Complete Guide for Garment Manufacturers
GSM (Grams per Square Meter) is the most critical specification in fabric purchasing. This comprehensive guide explains everything garment manufacturers need to know about GSM selection.
What is GSM in Fabric?
GSM stands for Grams per Square Meter and is the universal measurement of fabric weight in the textile industry. When sourcing knitted fabrics from manufacturers like Tahir Collection, understanding GSM is fundamental to getting the right fabric for your garment application.
GSM Ranges and Their Applications
Lightweight Fabrics (80-150 GSM)
Lightweight single jersey fabrics in the 80-150 GSM range are ideal for summer T-shirts, athletic wear, and garments requiring breathability. These fabrics are popular with manufacturers targeting the US and European summer markets.
Medium Weight Fabrics (150-250 GSM)
The most versatile range for garment production, medium-weight fabrics cover standard T-shirts (160-180 GSM), polos, casual shirts, and basic innerwear. This is Tahir Collection most popular production range.
Heavy Weight Fabrics (250-400+ GSM)
Heavy fabrics in this range include sweatshirt fleece, winter hoodies, and thick rib knits. French Terry and loop-back fabrics typically fall in the 280-380 GSM range.
How GSM Affects Your Business
Choosing the right GSM directly impacts your material cost, garment weight, customer perception, and compliance with buyer specifications. European and US buyers typically specify exact GSM requirements in their purchase orders.
