Total Square Feet
How to Calculate Square Footage
Square footage (sq ft) is calculated by multiplying length by width for rectangular rooms. For L-shaped rooms, break them into two rectangles and add the areas together. Square footage is used for flooring, painting, carpet, and tile estimates.
Square Feet = Length (ft) × Width (ft)
To convert square feet to square yards (for carpet pricing), divide by 9. To convert to square meters, multiply by 0.0929. Always add a 10% waste factor when ordering flooring materials.
