Do the math. You probably know how to calculate the square footage of a simple room without any funny shapes. Just break out your measuring tapeâor a laser measureâto get its length and width. Multiply the width by the length and voila! You have the square footage. Say a room is 20 feet wide by 13 feet long, then 20 x 13 = 260 square feet. How to calculate square feet.
Measure the length and width of the floor in a square or rectangular room, and multiply the figures together to get the floor area in square feet. For example, in a room that is 10 feet wide and 18 feet long, the area would be 10 multiplied by 18 to obtain 180 square feet.If you need the area of the ceiling, and the ceiling is flat and parallel to to the floor, then simplify your life by just computing the floor measurements -- they are the same.or example, in a room that is 10 feet wide and 18 feet long, the area would be 10 multiplied by 18 to obtain 180 square feet.
