How to Calculate Square Footage
Calculating square footage is a fundamental step for any home improvement project, whether you are installing new flooring, painting a room, or laying sod in your backyard. The basic formula for a rectangular area is:
Length (ft) × Width (ft) = Total Square Footage
Measuring Tips for Accuracy
- Measure in Feet: If you measure in inches, divide the final inch count by 12 to get feet before multiplying, or divide the total square inches by 144.
- Break Down Complex Rooms: If a room is "L" shaped, divide it into two smaller rectangles, calculate each area separately, and then add them together.
- Account for Waste: For flooring or tile, it is industry standard to add 10% extra for cuts, breakage, and waste.
