Plans drawn at 1/4 inch = 1 foot scale correspond to which scale ratio?

• A. 1:16
• B. 1:48
• C. 1:24
• D. 1:32

Answer: (B)

Converting plan measurements to real-world size requires comparing drawing units to actual units. Here, 1/4 inch on the plan represents 1 foot in reality. Convert feet to inches: 1 foot = 12 inches, so 1/4 inch on the drawing corresponds to 12 inches in real life. The scale factor is real size divided by drawing size: 12 inches ÷ 0.25 inch = 48. That means 1 unit on the drawing equals 48 units in real life, so the scale is 1:48. In practical terms, 1 inch on the plan equals 48 inches (4 feet) in reality.
