Square Footage Calculator

Square footage calculation depends on the shape:

• Rectangle/Square: Length x Width
• Circle: Pi x Radius² (or Pi x (Diameter/2)²)
• Triangle: (Base x Height) / 2
• Trapezoid: ((Base1 + Base2) / 2) x Height

Our calculator handles all the math for you - just enter your measurements.

To convert between square feet and square meters:

• Square feet to square meters: Multiply by 0.0929
• Square meters to square feet: Multiply by 10.764

Our calculator automatically shows results in multiple units so you don't need to convert manually.

Yes! For irregular shapes, break them down into basic shapes:

• Divide the area into rectangles, triangles, or circles
• Calculate each shape separately using our calculator
• Use the "Add Area" button to combine multiple shapes
• The calculator will give you the total combined area

This method works for L-shaped rooms, complex floor plans, and any irregular space.

Square footage is used in many applications:

• Real estate: Measuring home and property sizes
• Flooring: Calculating materials for tile, carpet, or hardwood
• Painting: Estimating paint needed for walls
• Landscaping: Planning gardens, lawns, and patios
• Construction: Estimating materials and costs
