1 Square footage: To measure commercial square footage, multiply the length of the room in feet by its width. 2  For example, a room that is 12 feet (3.7 m) long by 12 feet (3.7 m) wide is 144 square feet (13.4 square m).3  12x12=144.4  Unusual shapes: Take care when measuring irregularly shaped sections of a room. If the length of the space with the diagonal wall was 10 feet (3.0 m) and its width was 8 feet (2.4 m), the square footage of the area would be 40 feet (3.7 square m). 2  That is because the wall cuts the total square footage, which would have been 80 if the room had no wall intersecting it, in half. 3  10x8=80 and 80/2=40.
