How do I calculate square footage? Square footage is based on multiplying the length of an area x width of that area. What about non-rectangular areas? In those instances, you need to break the area down into smaller rectangles. For instance, an L-shaped surface can be broken into 2 smaller rectangles (see illustration below). Add the 2 areas (100 + 200 = 300 sq ft) to get a total.
