Calculate the area of simple or complex shapes in square feet, yards, meters, and acres.
The calculator uses standard geometric formulas to find the area of each shape:
Imagine an L-shaped driveway made of two rectangles: a main section (50ft x 12ft) and an extension (20ft x 10ft).
The Square Footage Calculator is a versatile and powerful tool designed for homeowners, contractors, landscapers, and estimators who need to accurately determine the area of a given space. Whether you're planning a flooring project, ordering materials for a new driveway, seeding a lawn, or painting a wall, calculating the precise square footage is the critical first step. This calculator simplifies that process by handling various geometric shapes and complex layouts, providing instant and accurate results in multiple units (square feet, yards, meters, and acres). By eliminating manual calculations and potential unit conversion errors, it saves time and helps prevent costly mistakes in material purchasing.
What sets the Square Footage Calculator apart is its "Complex Area" functionality. While many basic calculators can handle a simple rectangle, real-world projects are rarely so straightforward. A room may be L-shaped, a parking lot may have landscape islands, or a patio might be a combination of a square and a semi-circle. This tool's ability to add and subtract multiple sub-areas allows users to "build" their project's exact shape, ensuring a highly accurate final measurement. This feature is indispensable for creating precise estimates, which is a cornerstone of effective project management as detailed by organizations like the Project Management Institute. By accounting for every nook, curve, and cutout, you can order materials with confidence.
Furthermore, the Square Footage Calculator is built for convenience, incorporating a seamless unit conversion engine. Users can enter dimensions in feet, yards, or even meters—or mix and match units within a complex calculation—and the tool automatically harmonizes them into a standard base unit for calculation before presenting the final area in all common formats. This removes a significant point of friction and a common source of error in manual estimating. The underlying geometric principles are fundamental, and for those interested in the mathematical theory, Wikipedia's article on Area provides an excellent academic overview.
Ultimately, the Square Footage Calculator serves as a reliable first step in the planning phase of any project involving physical space. It empowers users to move from rough guesses to data-driven estimates. By providing a clear and accurate measurement of the total area, it allows for better budgeting, reduced material waste, and more efficient project execution. Use the Square Footage Calculator to ensure your next project starts on a solid, accurately measured foundation.

Select the "Complex Area" option. Break the 'L' shape into two separate rectangles. Click "Add Sub-Area" twice. For each one, select "Rectangle", enter its dimensions, and make sure the type is set to "Add". The calculator will sum their areas for the total.
The "Subtract" feature is for removing an area from a larger one. For example, if you are calculating the square footage of a yard for new sod, but it has a circular flower bed in the middle, you would first 'Add' the rectangular yard and then 'Subtract' the circular bed to get the correct net area.
In the "Complex Area" mode, yes. Each sub-area has its own unit selector, and the calculator will convert them correctly. For simple shapes, all dimensions must use the same selected unit to avoid confusion.
A trapezoid is a four-sided shape with at least one pair of parallel sides. These parallel sides are called the bases ('a' and 'b'). The height is the perpendicular distance between these two bases. It's common for decks, unique rooms, or property lots.
