Guide to Thread Size

Thread size relates to the thickness. With yarn, the higher the number, the thicker the yarn is. This makes sense to us, but the opposite is true when it comes to crochet and tatting threads.

With thread, the higher or larger the number of the thread, the thinner it is. For example, size 3 is a thicker thread than a size 40 and a size 80 is smaller than a size 40.

Refer to the images below for a comparison of all five sizes of the Lizbeth® brand thread.
