First, determine the square footage of the room (don’t forget the closets!); just multiply the room’s length by its width.
[Length of Floor] x [Width of Floor] = Total Area.
Choose your tile size from the following list and use the accompanying equation to figure out the number of tiles to buy:- 4-inch tiles: Total Area ÷ 0.1089 = Number of 4-inch tiles needed
- 6-inch tiles: Total Area ÷ 0.25 = Number of 6-inch tiles needed
- 9-inch tiles: Total Area ÷ 0.5625 = Number of 9-inch tiles needed
- 12-inch tiles: Total Area = Number of 12-inch tiles needed (you’ve measured your room in square feet, and a 12-inch tile is 1 square foot)
- 18-inch tiles: Total Area ÷ 2.25 = Number of 18-inch tiles needed
You can always bring your room dimensions to a tile dealer, who can help you figure out how much tile and other supplies to purchase.
