Tex
SewingTex Weight
Description
A direct metric system for measuring thread thickness, where a higher number indicates a heavier and thicker thread.
Detailed explanation
The Tex system determines thread weight by measuring how many grams 1,000 meters of that specific thread weighs. Unlike the ‘wt’ system, Tex is a direct numbering standard, meaning the number increases as the thread gets thicker. For instance, fine threads for lightweight fabrics might be Tex 20, while standard all-purpose polyester thread usually falls around Tex 30 to 40.
