Measure the Surface
Enter the length and width of the rectangular floor or wall area you want to cover. For irregular spaces, divide the project into smaller rectangles and calculate them separately.
Estimate the number of tiles and boxes needed for a rectangular floor or wall, including waste and material cost.
TILE PLANNING GUIDE
A useful tile estimate starts with the total surface area, then compares it with the size of one tile, adds a waste allowance, and rounds the required quantity up to complete boxes. Use these six planning steps with the calculator above before purchasing material.
Enter the length and width of the rectangular floor or wall area you want to cover. For irregular spaces, divide the project into smaller rectangles and calculate them separately.
Use the tile dimensions shown on the packaging. The calculator converts centimetres to metres and finds the area covered by one tile.
The surface area is divided by the area of one tile. Because partial tiles cannot be purchased as a complete unit, the result is rounded upward.
Extra tiles help cover cuts, breakage, pattern layout and future repairs. The calculator lets you add a waste percentage before determining the final quantity.
Enter how many tiles are packed in one box. The calculator rounds the required quantity up to complete boxes and shows how many tiles will be purchased.
After the box count is calculated, the tool shows the purchased quantity, spare tiles and total purchased coverage. Add a price per box to estimate material cost.
Actual tile requirements can change with room shape, diagonal or patterned layouts, grout spacing, cuts, breakage and installer methods. Complex projects may need a larger waste allowance than simple straight layouts.
Check the tile size, tiles per box and batch information on the product you intend to buy. The calculator estimates tile quantity, boxes and basic material cost; adhesive, grout, trims, labour, delivery and other project expenses are not included.
