Square Footage Calculator results are estimates for planning a project. Check measurements on site before you order materials or sign anything.
Measurements and results
The calculator is only as accurate as the measurements typed into it. Rounding in the display can differ from a figure worked by hand by a hundredth. Material amounts depend on the product, the layout and the installer, so follow the maker's instructions for coverage and waste.
Real estate figures
Guides on home square footage explain published measuring standards. They are not an appraisal, and they are not legal advice. A listing, an appraisal and a tax record can each report a different number for the same home.
Independent site
Square Footage Calculator is an independent site. It is not affiliated with any standards body, lender, government agency, or maker named in its guides. Names are used only to identify the source of a figure.
