What this site is
Square Footage Calculator Free is a set of free area calculators for floors, rooms and land. Everything runs in your browser. There is no login, nothing to install, and the tools keep working offline after your first visit.
How the numbers are checked
Every result comes from one tested script that uses exact conversion factors, such as 1 foot = 0.3048 meters and 1 acre = 43,560 square feet. Every worked example on the site is a test that runs each time the site is built, so the examples and the calculators cannot drift apart.
Who runs it and its limits
This is an independent site. It has no affiliation with any store, flooring maker or real estate service. Results are estimates for planning, not a survey, appraisal or quote, so measure twice and confirm quantities with your installer or supplier before you buy.
