Intro
Finding the right thread size starts with understanding how it is specified. This chapter provides a clear guide to sewing thread numbering and helps make different systems easier to navigate.
Short definition
Sewing thread numbering describes the fineness or linear density of a sewing or embroidery thread using internationally recognised numbering systems such as Tex, Nm, denier and ticket numbers. Understanding these systems is essential for comparing thread sizes, selecting suitable sewing threads and ensuring consistent sewing performance across different applications.

FAQ
-
A textile numbering system defines the thickness or fineness of fibers, yarns, and threads. It is based on the relationship between length and weight.
-
Different systems developed historically in various countries and industries. This makes it necessary to understand and convert between them.
-
Depending on the system, higher or lower numbers indicate finer threads. The interpretation depends on whether a length-based or weight-based system is used.
-
It helps select the correct thread for a specific application. Incorrect thread size can affect seam quality and performance.
-
The Tex system is the international standard. It is widely used across the textile supply chain.
-
Not easily, as they are based on different principles. Conversion tables are often required.
-
Yes, thread thickness influences strength, appearance, and sewability. Choosing the right size is essential.
-
It ensures correct communication and material selection. This reduces errors and improves production efficiency.
