How to Calculate Square Footage
Square footage measures the surface area in square feet. It is widely used in real estate, flooring, painting, and construction projects.
Area (Square Feet) = Length (feet) × Width (feet)
If your measurements include inches, convert the inches to a decimal fraction of a foot by dividing the number of inches by 12 (for example, 6 inches = 0.5 feet).
