About this calculator
Work out how many tiles and boxes a floor needs. The calculator divides the room area by the area of one tile and adds an allowance for cuts and breakage.
How it works
- Tiles are the room area divided by the tile area, times (1 plus waste divided by 100), rounded up.
- Room size is in metres and tile size is in centimetres.
- Boxes are the tiles divided by the tiles per box, rounded up.
This is a preliminary estimate for planning and shopping lists. It is not a structural design, a safety check or a building-code approval. Ask a qualified professional before you build.
Common questions
How much extra should I buy?
Ten percent is a common allowance, and more for diagonal layouts or small rooms with many cuts. Adjust the figure to your job.
Why keep spare tiles?
Colours can differ between batches, so spares from the same batch help with future repairs.
