⏹️Square Footage Calculator

Square footage (sq ft) is a measurement of area, typically used for rooms, houses, plots of land, or materials like flooring and paint coverage.

Multiply the length (in feet) by the width (in feet). Formula: Area = Length × Width.

Use the formula: Area = π × radius² (where π ≈ 3.14159). If you have the diameter, the radius is diameter / 2.

Use the formula: Area = 0.5 × base × height.

Break the irregular shape into smaller, regular shapes (rectangles, triangles, circles). Calculate the area of each individual shape and then add them together using the “Add to Total” feature of this calculator.

It’s essential for estimating materials like flooring, paint, wallpaper, tiles, sod, or mulch, helping you buy the right amount and avoid waste or shortages.

Yes, this calculator assumes all input dimensions are in feet to output square feet. If your measurements are in inches, divide them by 12 to convert to feet before entering them.

Measure the main rectangular area of the room. Then, measure each alcove or closet area separately (usually as smaller rectangles) and add their square footage to the main area’s total.

Yes, it’s generally recommended to add 10-15% to your total square footage for waste (due to cuts, mistakes, or pattern matching) when purchasing materials like flooring or tiles.

This calculator focuses on providing the area in square feet. For conversions (e.g., to square yards or square meters), you would use standard conversion factors (1 sq yd = 9 sq ft; 1 sq m ≈ 10.764 sq ft).
