How the tile calculator works
Estimate the number of tiles for a rectangular floor, wall or backsplash. Enter project dimensions and tile size, then choose a waste allowance for cuts and breakage.
Tile count = project area ÷ tile face area, rounded up and increased by the selected waste allowance. The calculator is designed to give a useful first-pass material estimate while keeping the assumptions visible. For a purchase, compare the result with the product packaging or supplier quotation.

Frequently asked questions
How much tile waste should I allow?
The right allowance depends on layout, cuts, pattern and tile shape. A simple rectangular layout typically needs less waste than a complex pattern.
Should I buy extra tile from the same batch?
Yes. Color and shade can vary between manufacturing batches, so keeping spare tiles can be useful.
Can I use this for wall tile?
Yes. Use the wall length and height as the project dimensions.
Does this include grout?
No. Use the separate grout calculator for an estimate.
