How the Tile Calculator Works

A simple estimate to help you plan before ordering materials.

Calculation method

We divide the rectangular surface area by the physical tile face area (without grout), round up to whole tiles, then apply your waste allowance to the rounded tile count. We round up again to whole tiles and full boxes. Grout joints are shown for planning but are not subtracted from the tile purchase estimate. This conservative area-based method does not simulate a cutting layout.

Example: A 4 m × 3 m room with 60 cm × 30 cm tiles and 3 mm grout joints requires 67 tiles before waste, 74 including 10% waste, or 10 boxes of 8 tiles. Always confirm the manufacturer's stated coverage, tile pattern, cuts, breakages and actual room shape before purchasing.

Important: This is an area-based estimate, not a cutting layout. Small rooms, narrow strips, diagonal layouts, niches and complex patterns may require extra tiles. Costs exclude adhesive, grout, labour, delivery and taxes. Currency selection changes the displayed currency only; it does not convert prices at exchange rates.
