Tile Calculator

Tiling a floor, wall, or backsplash requires careful planning to purchase the right quantity. Running out mid-project can be a problem if the batch or shade is no longer available.

This calculator divides the total room area by the area of a single tile and adds 10% for waste — which covers cuts along edges, breakage, and future replacements. For diagonal or herringbone layouts, increase the waste factor to 15–20% since more cutting is required.

Common tile sizes include 300x300 mm, 600x600 mm, and 300x600 mm. Larger tiles cover floors faster but produce more waste in small rooms. Always buy tiles from the same production batch to ensure consistent colour matching. Store a few spare tiles for future repairs.
