📖 About Tile Calculator

Tile Calculator helps homeowners and contractors determine exactly how many tiles are needed for any floor or wall project. Enter the room dimensions and tile size, set the waste percentage for cuts and breakage, and get the total number of tiles plus a cost estimate. Standard waste is 10% for straight layouts, 15% for diagonal patterns. The tool also estimates the number of boxes needed (assuming 8 tiles per box). Perfect for kitchen renovations, bathroom remodels, and flooring projects. All calculations are instant, private, and run entirely in your browser. Common tile sizes include 30×30cm for walls, 60×60cm for floors, and 30×60cm rectangular tiles. The box estimate assumes 8 tiles per box, which is standard for most 60×60cm porcelain tiles.
