📐 Square Footage
Calculate area for any room or shape
About this calculator
Square footage is the starting point for nearly every home project. Enter the length and width of a room (in feet, inches, metres, or centimetres) and get the area in square feet and square metres instantly. For irregular rooms, add multiple rectangular sections or an L-shape breakdown and the calculator totals them for you. Results show in both square feet and square metres, since Canadian listings and building materials often mix the two systems.
Tip: always measure at the longest points and round up — flooring and paint suppliers expect slightly generous numbers, not exact ones.
