How to calculate square footage
Measure length and width, convert both to feet, and multiply them. Add separate rooms or work areas to get a combined total.
Measuring rooms and areas
Measure wall-to-wall at the same level. For feet and inches, you can enter inches directly and the calculator converts them to feet.
Common uses
