🔍 What Is Square Footage?

Square footage is the measurement of a two-dimensional space in square feet (ft²). It's most commonly used to describe the size of rooms, floors, land, or other flat surfaces.

Formula (for rectangles/squares):

Area = Length × Width

For irregular shapes, the area may need to be broken into sections and added together.

🧮 How to Use the Square Footage Calculator

1. Enter the length and width of the space in feet
2. (Optional) Use inches for more precision
3. Click “Calculate”

The tool will instantly return the total area in square feet. For more complex shapes, you can input multiple areas and add them together.
