When you are planning your project and purchasing supplies it is important to be able to estimate approximately how many tiles you will need based on the size of the space. For a 100 square foot tile project, you will need to install a total of 100 12×12 tiles.
This is simply the square footage of the space divided by the area of each tile. For example, if the square footage of the space is 120 square feet and each tile is 12 inches by 12 inches, the calculation would be 120 square feet / (12 inches x 12 inches) = 120 square feet / 144 square inches = 0.83 tiles.
For example: If each tile is 1 square foot, you will need 120 tiles to conceal a 120 square foot area. You will need to purchase 12 boxes of tiles if each box contains 10 tiles.
If the area of your wall or floor is 50 square feet, you would need 200 tiles at minimum to cover the area (50 / 0.25).
For a 100 square foot tile project, you will need to install a total of 100 12×12 tiles. But some tiles could be damaged during transport or installation or maybe otherwise unusable. It's customary to purchase an additional 15 percent above the exact calculated amount of tile.
Multiply the width and length of the tile to find the area it will cover; then, divide by 144 to convert the measurement to square feet. Next, divide the area of the room by the square footage of a single tile. This will tell you how many individual tiles you need to purchase.
Dimensions: Each tile measures 12 x 12 inches and 1.2mm thick. There are 45 tiles per box, which will cover 45 square feet.
The 2×2 Feet or 600×600 Mm consists of 4 pieces packed in one box. The area covered will be 15.5 SQ FT or 1.44 SQM.
Typically, installing ceramic or porcelain tile costs $3-5.5 per square foot, depending on local labor rates and size of the project. Stone tile installation costs are $5-8 per square foot. Installing mosaic tile can cost as much as $9-20+ per square foot, depending on the complexity of design you are looking for.
The manufacture specifies 3/16 of an inch for grout spacing.
Tile Sizes & Shapes
From traditional to truly unique, floor tile is available in all shapes and sizes these days. The tried-and-true 12” x 12” tiles are still popular, but tiles are tending to be larger and larger.
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).
Measurements, Sizes, and Patterns
Tiles are commonly referred to by their "nominal" sizes which might not be the "true" measurement of the material. An example of this is when a 12" x 12" porcelain tile has a "true" measurement of 11-7/8" x 11-7/8".
You can calculate it on any calculator, just use the total number of square feet in your room, divide by “4” which is the number of square feet covered by one 24 x 24 inch tile. Take that result and multiply times “1.15” to find the total number of tiles to order when the design you want is 24 x 24 inches.
For example:- if the room is 2600mm wide, divide by the tile width 300mm = 8.66 tiles, so round this up to 9 tiles. To get the total number of tiles for the floor, multiply the number of tiles for the length with the tiles for the width, 8 x 9 = 72 tiles required to do the job.
Square footage: 288 sq. ft.
Living room: 12 feet x 15 feet = 180 square feet.
A small 3x6” tile can be set with a 1/16” or 1/8” line, while a mid-size tile like 6x12” or 13x13” would be better with an 1/8” grout line. A large tile, such as 12x24”, usually requires a 3/16” grout line, so it's best to check the manufacturer's recommendations to see how small you can go.
Measure the length in feet, Measure the width in feet. Multiply the length figure by the width figure. This will be your total square footage for that portion of your project. Continue to repeat this for all parts of the space that will get the same tile.
