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.
The formula for figuring square footage is Length x Width. Example: A room that is 20 feet long and 30 feet wide = 600 square feet. Once you have measured each area with notes as to what type surface is on the floor, you can add them up for the total square footage that is in the building or area.
