Area-based estimate excluding grout gaps. Layout and cuts affect waste; purchases round up to whole boxes.

Formula and method

Tiles = round up(area including waste ÷ tile area). Boxes = round up(tiles ÷ tiles per box). Cost = boxes × box price.

Worked example

A 20 m² room with 60 × 60 cm tiles and 10% waste needs 62 tiles. With 4 per box, buy 16 boxes containing 64 tiles.

Frequently asked question

Is 10% waste enough for every layout?

10% is an initial assumption. Diagonal patterns, cutouts and complex cuts may need more. Check the layout with your installer before purchasing.
