Calculate square footage for any room or space with our free calculator, useful for flooring, painting, carpeting, or general real estate purposes.
For rectangular spaces: Square Footage = Length × Width. For irregular shapes, break the space into rectangular sections, calculate each separately, then sum the totals.
Use π × radius² (radius being half the diameter) rather than the standard length × width formula for rectangles.
Many calculators offer unit conversion; check for a units toggle if you need square meters instead of square feet.
This depends on your project, flooring often needs 5-10% extra for cuts and waste, similar to tile calculations.
Divide the room into rectangular or triangular sections you can measure individually, calculate each section's area, then sum them for the total.
