Enter the area and the size of your tiles to find how many tiles, and how many boxes, you need to buy.
Count the tiles for a floor, a wall or any other area.
Each tile takes up its own size plus the gap, which is the grout line, so a 12 inch tile with a 0.25 inch gap covers a 12.25 inch square. The calculator divides the area by the area of one tile with its gap and rounds up to a whole tile. If you also give the number of tiles in a box, it rounds up to a whole number of boxes.
Tiles get cut around edges and corners, and some break or have flaws. Most installers buy 5 to 10 percent more than the count. The result shows that range in tiles and boxes, and in cost if you enter a price. Buy extra tiles from the same batch, since the shade can change a little from one batch to the next.
You can price tiles by the tile, by the box, or by area in square feet, inches, yards, meters or centimeters. Pricing by the box uses the number of boxes rounded up, and pricing by the tile uses the rounded up number of tiles. Pricing by area uses the exact area to cover, with no waste.
Divide the area of the floor by the area of one tile, including its gap, and round up. Then add 5 to 10 percent for cuts and breakage.
Plan on 5 to 10 percent extra. Use more, around 15 percent, for diagonal patterns or rooms with many corners.
Yes. The gap adds to the size each tile takes up. It makes a small difference for large tiles and a bigger one for small tiles.
Multiply the length by the width. For a room of 20 by 15 feet, the area is 300 square feet.
It is printed on the box, along with the area the box covers. Enter the tiles per box here to see how many boxes to buy.
