What is Tex Weight?

It’s common to see threads labeled with a “Tex” Number. But what does that number mean? Tex, or Tex Weight, is a standard way of measuring thread weight that’s deceptively easy to understand: the higher the Tex, the thicker the thread. That’s all there is to it!

A thread’s Tex is equal to the weight in grams of 1000 meters of that thread, so a heavier thread has a higher Tex. For example, if 1000 meters of a thread weighs 30 grams, it is Tex 30. Typical light-weight sewing threads range from Tex 8-25, medium-weight sewing threads are Tex 25-40, and heavy-weight sewing threads are Tex 40 and up.

We know that sewing thread weights can be confusing, so we put together a handy chart of some equivalents between commonly used thread weights to help you find the perfect match. Find an estimated equivalent on the chart below, or convert a thread weight on your own using our thread conversion chart.
