To determine the square footage of a square or rectangular room, measure the length and width of the room in feet or inches and enter the values in Area 1 of the calculator below.  For irregularly shaped areas or multiple rooms, it is helpful to draw a diagram and divide the room up into sections. Treat each section as a separate area, as in this illustration. Input the measurements of each area below to see the total SQFT needed.
