Threadology



WISE WORDS FROM MOTHER SUPERIOR

Have you wondered why thread gets thinner as the weight or thread size number gets larger? It is confusing but there is a reason behind this system. Here is a simple analogy to illustrate why: The goal is to determine how much thread it takes to weigh one pound.

  1. Thread A takes 20 miles to weigh a pound so it is labeled as 20 wt.
  2. Thread B takes 40 miles to weight a pound and is labeled 40 wt. It is a finer thread because it takes 40 miles to weigh one pound.
  3. Thread C takes 60 miles to weigh a pound so it is even finer yet.
