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 square footage of a space is essentially its area, meaning you'll need to multiply the length by the width. For example, a room that is 10 feet long and 12 feet wide would be calculated as follows: 10 feet x 12 feet = 120 square feet. Add the third dimension.
