Here is how to properly measure and calculate total square footage of the space. 1  Split the room into separate areas. 2  Measure each area of the room separately (area 1, area 2, area 3). 3  Calculate the square footage of the each space by multiplying length by width. 4  Room: Length (ft) x Width (ft) = Square Footage.
