How is thread measured?

How is thread measured?

It can be confusing trying to understand thread measurements.  Commonly quilters use weight, embroiderers denier, and seamstresses tex to describe thread thickness.

We’re here to clear that all up for you!  Well, sort of.

Weight:  the larger the weight, the thinner the thread

Tex:  the larger the tex, the thicker the thread.

Denier:  the larger the denier, the thicker the thread.

Composition:  the larger the number (#), the thinner the thread.

Confused yet?  Let’s get an expert’s help.  In this video, Dr. Bob explains how threads are measured.


Long story short?

You don’t have to know the exact weight or thickness of a thread.  These numbers are ball-park range guesses any way.  Decide if you want the thread to blend or show.  If you want a thread to blend, look for a 50-100 wt thread.  If you’d like the thread to show, look for a 10-40 wt thread.  Remember, like Dr. Bob explained, not all thread types and thicknesses are the same.  Look for a general thread description that will fit your project.

    I have tried to search your sight for 30 weight threads and it does not come up....which of your threads are 10-30 superior threads....
