How do you measure a floor for flooring?
To do so, use a tape measure to determine the room's length and width. Then multiply the length by the width to get your square footage. For instance, if the room is 12 feet wide and 12 feet long, you will need enough flooring for 144 square feet (12×12=144).
How do I calculate how much tile I need for my floor?
Multiply the tile length by the width to figure the area that one tile will cover in square inches. Divide the result by 144 to convert it to square feet. Then, divide the area you're tiling by the square footage of one tile to determine how many tiles you need.
