What is a Square Footage Calculator?

This tool calculates the total area (in square feet or square meters) of a room or space based on its length and width, and can combine multiple rooms into one total. It's commonly used for flooring estimates, paint coverage, real estate listings, and general room planning.

Formula Used

Square Footage = Length × Width. For irregular spaces, the area is typically broken into rectangular sections, each calculated separately and then summed together for the total.

How to Use This Tool

Enter the length and width of your room or space in feet (or meters), and the calculator returns the total square footage. For multiple rooms, add each one and the tool sums the total.

Examples

Example: A room measuring 12 feet by 15 feet has a square footage of 12 × 15 = 180 square feet.

Frequently Asked Questions

How do I calculate an L-shaped room? Split it into two or more rectangles, calculate each section's square footage separately, then add the totals together.

How much flooring should I order beyond the exact square footage? Most flooring professionals recommend ordering 10% extra to account for cuts, waste, and pattern matching.

Is square footage the same as square meters? No — they are different units. 1 square meter equals approximately 10.764 square feet, so convert before comparing measurements in different systems.

Does square footage include closets and alcoves? This depends on the purpose — for flooring, usually yes, since material is still needed there; for real estate listings, conventions vary by region and agent.

How is square footage used in real estate? It's used to estimate a property's living space, often as a factor in pricing, though official measurement standards can vary by country and listing service.
