Over he past 30 years, the Micron measurement has evolved to become the predominant term used commercially to describe the fineness of a wool fiber.

Merino wool falls into the 18-24 micron range. The 25-32 micron, medium range wool, is usually defined by the word "Shetland", and is used in such applications as blankets and knitwear apparel.
