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.
For instance, if your room is 12 feet by 14 feet, it is a total 168 square feet in size. If you are tiling a small room, measure the width and length of the floor in inches. Multiply the width and length together and then multiply that number by 144 to convert it to square feet.dd that number to the total square feet of the room. For example, 10 percent of 168 is 16.8. Rounded up, the number becomes 17. Adding 17 to 168 equals 185. This is the total number of square feet of tile you need.
