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.
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. Again, round up to the nearest whole number.
Estimate the number of tiles you need by determining the square footage of the area you're tiling plus the square footage of each tile. For example, if you're adding a tile floor to a 100-square-foot bathroom, and each tile is 12″ x 12″ (one square foot), you'll need about 100 tiles.
Step 4: Calculate the number of tiles needed:
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.
How many square feet is a 20x20 room? The square footage of a room 20 feet wide and 20 feet long is 400 square feet. The square footage is found by multiplying the width (20 ft) by the length (20 ft).
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 manufacture specifies 3/16 of an inch for grout spacing.
Delivery Time: 8 DAYS. Packaging Details: Size :30X30 CM (12X12 Inch)Packing :1 Box = 10 PcsThickness :8-9 mmWeight :1 Box = 12 KgWork Area :1 Box = 9.69 Sq.
Multiply the length and width of the space you want covered — like from the counter to the cabinets in a kitchen — by 12 to get each measurement in inches. Multiply these two numbers together to get your area, then divide that number by the area of the tile to get the number you will need.
The picture of the tile figures may also be described by an equation in y = mx + b form, where x and y are variables and m represents the growth rate and b represents the starting value of the pattern.
How many square feet is a 12x12 room? The square footage of a room 12 feet wide by 12 feet long is 144 square feet. Find the square footage by multiplying the width (12 ft) by the length (12 ft).
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 length by the width and you'll have the square feet. Here's a basic formula you can follow: Length (in feet) x width (in feet) = area in sq. ft. Tip: If you can't picture what a square foot is, try drawing a square that is 1 foot tall by 1 foot wide—you've got one square foot!
White Porcelain Subway Tile Matte Finish 12" X 24" (Box of 14 Sqft- 7 PCS), Wall Tile, Floor Tile, Bathroom Tile.
Finished grout lines will vary from 1/16" to 3/16". However, the actual finished grout spacing will vary from 1/8" to 1/4" if 3/16" spacers are used. If smaller spacers, like 1/8", are used it will accentuate the size difference of handmade tile.
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.
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. Pressed tiles with a 1/16" grout line.
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.
An easier visual might be to imagine your standard high school classroom. That's about equal to 500 square feet. Even without all the desks crammed in, that's not a huge space. It's actually only slightly larger than a hotel room, which is typically between 400 to 450 square feet when you add in the bathroom.
Square footage: 256 sq. ft.
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.
