What range do small micrometers typically have?

• A. 2-inch range
• B. 1-inch range
• C. .5-inch range
• D. 10-inch range

Answer: (B)

Micrometers are precision tools with a fixed measuring range, and for small parts the typical choice is a 0 to 1 inch range. This range covers the common dimensions of tiny features and allows reading fine increments on the thimble with good resolution. Larger ranges like 2 inches or 10 inches are used for bigger parts, while a very small 0.5 inch range is uncommon for standard general-purpose sets. So, a 1-inch range is the best fit for a small micrometer.
