Square Footage Calculator
Enter the length and width to get the area. Useful for rooms, yards, flooring, and more.
Live calculator output
Enter length and width to see the area.
How it works
Area is calculated by multiplying length by width: Area = Length × Width. The calculator also converts between square feet and square meters (1 sq ft = 0.0929 sq m, or 1 sq m = 10.764 sq ft). This is essential for ordering flooring, estimating paint coverage, valuing real estate, and planning garden layouts.
Practical example
A room that is 12 ft × 10 ft has an area of 120 sq ft (about 11.15 sq m). This means you need at least 120 sq ft of flooring material. For carpet or tile, add 10% for waste and cuts — so order about 132 sq ft.
Frequently asked questions
Reusable FAQ content keeps each calculator page richer for users and search engines.
How do I convert sq ft to sq m?
Multiply square feet by 0.0929 to get square meters.
What about ceiling height?
This calculates floor area only. Multiply by height to get cubic footage for volume.
How much flooring should I order?
Order 10-15% more than the calculated area to account for cuts, waste, and pattern matching.
What is the average room size?
A standard bedroom is about 120-150 sq ft (11-14 sq m). A living room is typically 200-400 sq ft (19-37 sq m).
