Most rulers and tapes used by the carpenter have increments of ____ inches.

• A. 12
• B. 20
• C. 16
• D. 18

Answer: (C)

The main idea is that carpentry tools are designed around the standard framing spacing most often used in construction. In residential framing, studs are placed at 16 inches on center, so rulers and tape measures are marked to accommodate measuring in those 16-inch blocks. This lets a carpenter quickly locate studs, lay out layouts, and estimate material needs without doing extra math. Other spacings, like 12, 18, or 20 inches, aren’t the usual standard for framing, which is why 16 inches is the typical increment you’ll see on most rulers and tapes.
