Why Yarn Count is Important

Yarn count is an important part of garment merchandising. It is used for fabric booking, costing and yarn sourcing. Since fabric makes up a large portion of a garment's cost, choosing the right yarn count is very important.

Important Note

Yarn counts are usually available in even numbers. So, if the calculated result is an odd number or contains decimals, adjust it to the nearest practical yarn count used in production.

These formulas are used for quick estimation during fabric sourcing, costing, and yarn selection. The final yarn count may differ depending on factors such as fabric construction, machine gauge, stitch length, yarn quality, finishing process, and factory requirements.
