What is the average width of a human hair?

Europeans consider hair with a diameter of 0.04 to 0.06 mm as thin, hair with a diameter between 0.06 and 0.08 mm as normal, and hair with a diameter between 0.08 and 0.1 mm as thick. By comparison with European hair, Asian hair is significantly thicker. The average diameter of Asian hair is 0.08 to 0.12 mm.

How many thousandths of an inch is a human hair?

Jenna – if you have quoted the question correctly then the question is incorrect. The human hair IS APRROX 0.004′ (four thousands of an Inch and there are 12 inches to the foot)So therefore .004 divided by 12 is your answer. The thickness of a(n average) human hair is about 0.00388 of a ft.

According to Papanikolas, you can only really test if your hair is fine, medium, or coarse by doing a strand test. If you take a single hair in between your fingers and you don’t feel anything, then you have fine hair. If you can feel the hair, then it’s medium. If you feel a strong, thick strand, then you are coarse.
