How To Calculate Square Feet?
The mathematical formula for calculating square feet is simple multiplication. You will need to measure the area that you need the square feet for. Once you have the measurements of the area you will then use this equation. Width multiplied by the length and this will equal square feet. If you are measuring for carpet you will want to measure the widest part of the room and the longest part of the room. This will give you more carpet than you need but this is the way it must be done. If your room is 10 feet by 12 feet then your total square feet is 120 feet.
