Square Footage Calculator
Calculate room area in feet, inches and metric units
About Square Footage Calculator
This free online tool helps homeowners, renters and DIY renovators work out the floor area of a room. It accepts feet and inches together, including fractional inches, so measurements taken with a tape measure can be entered as they are. Rooms can be rectangular, L-shaped, circular or triangular, and several spaces can be added together into one total.
The calculator also supports decimal feet, inches, meters and centimeters, and it can mix units within a single project. Closets, alcoves and cutouts can be added or subtracted from a room, so the result reflects the usable floor. A separate flooring guide explains how to allow for waste and round up to whole boxes before buying material.
The site is aimed at people who want a quick, clear area figure and a plain explanation of the conversion steps. Its guides cover square feet, square meters and common room sizes, and results stay in the open tab until they are copied or printed.
