About Square Footage Calculation
The Square Footage Calculator estimates the square footage of a lot, house, or other surfaces in several common shapes. If the surface is complex in shape, it may be possible to section the surface into simple shapes and add the square footage together.
This calculator supports multiple shapes including rectangles, circles, triangles, trapezoids, sectors, and parallelograms. You can calculate area in different units and even estimate costs by providing a price per unit area.
Accurate Measurements
Always double-check your measurements for accurate calculations. Small errors can lead to significant differences in large areas.
Complex Shapes
For complex shapes, break them down into simpler shapes, calculate each area separately, and then sum them up.
Unit Conversion
Use the unit converter to switch between different area units based on your needs and preferences.
Cost Estimation
Use the price field to estimate material costs for projects like flooring, paving, or painting.
