Square Feet Calculator
Quickly determine the square footage of rooms, floors, walls, roofs, gardens, land, and other spaces with accurate measurements.
What Is Square Footage?
Square footage measures the total surface area of a space. It is commonly used for flooring, carpeting, painting, roofing, landscaping, construction projects, and property measurements. Knowing the square footage helps estimate material quantities and project costs.
How to Calculate Square Feet
Multiply the length by the width of the space after converting measurements into feet.
Formula:
Square Feet = Length × Width
If measurements are entered in meters, inches, or yards, they are automatically converted before calculating the final square footage.
Common Square Footage Examples
| Area | Square Feet |
|---|---|
| 10 × 10 | 100 sq ft |
| 12 × 12 | 144 sq ft |
| 15 × 20 | 300 sq ft |
| 20 × 20 | 400 sq ft |
| 25 × 40 | 1,000 sq ft |
