Which statement best describes the floor plan scale 1/4 inch = 1 foot?

• A. One quarter inch on the plan equals one foot in real size
• B. One quarter inch equals one meter
• C. One foot on the plan equals one foot in reality
• D. One inch on the plan equals one foot

Answer: (A)

Floor plan scales show how drawing measurements map to real sizes. When the scale is 1/4 inch = 1 foot, every quarter-inch drawn on the plan represents one foot of actual length. That means you can convert plan measurements directly to real dimensions by dividing the plan measurement by 0.25 inches per foot. For example, 8 inches on the plan would be 32 feet in reality (8 ÷ 0.25 = 32). Similarly, 1 inch on the plan equals 4 feet in reality (1 ÷ 0.25 = 4). This interpretation matches common architectural practice, often expressed as 1:48 in ratio form, since 1 inch on the plan corresponds to 48 inches (4 feet) in real size. The other statements would mix units or scales in ways that don’t reflect 1/4 inch representing one foot: for instance, tying a quarter-inch to a meter uses a different unit system; saying one foot on the plan equals one foot in reality would be a 1:1 scale; and saying one inch on the plan equals one foot would be a different, larger scale (1:12).
