Which ruler division is commonly used in inches?

• A. Sixteenths
• B. Eighths
• C. Quarter-inches
• D. Thirty-seconds

Answer: (A)

When measuring inches, you read not only whole inches but also fractions of an inch. The most common fractional divisions on a standard ruler are halves, quarters, eighths, and sixteenths. Sixteenths are the most widely used because they give you a practical level of precision (to 1/16 of an inch) without making the ruler too crowded with marks. That balance makes sixteenths the standard for everyday carpentry measurements. Eighths and quarters are coarser, so they’re quicker to read but less precise. Thirty-seconds exist on some rulers or in specialized tools, but they’re not as commonly used in general-purpose measuring as sixteenths.
