Terms of Use

Square Footage Calculator provides a free online calculator and educational articles about measuring area — square footage — for rooms, floors, yards and plots. By using the site you accept these terms.

Results are estimates based on the measurements you enter. Real rooms are rarely perfectly square, and flooring, tile and landscaping materials vary by product and installer — always measure carefully, allow for waste and cuts, and confirm quantities with your supplier or installer before buying. This site provides general information only and is not professional surveying, architectural or construction advice.

Area figures depend entirely on the measurements entered and on how a space is defined (for example, which parts of a home count as living area under local real-estate standards). Figures used in a sale, lease, planning application or contract should always come from a qualified surveyor, appraiser or installer who has measured the property.

We work to keep the calculator and content accurate and consistent with standard geometry and published conversion factors, but we do not guarantee that any result is correct for your individual circumstances, and we accept no liability for decisions — including material purchases — made in reliance on the site's output.

You may use the calculator freely for personal purposes. You may not scrape the site in a way that burdens its infrastructure, misrepresent the site's estimates as professional measurements, or remove attribution when quoting reasonable excerpts.

The site links to third-party websites, including Amazon. We are not responsible for the content, prices, availability or privacy practices of third-party sites. Purchases made on third-party sites are governed by their terms.

We may update these terms from time to time; the current version will always be posted on this page with its date.
