Formula
Tile area (m²) = (tile_length_mm / 1000) × (tile_width_mm / 1000) Net floor area (m²) = floor_length × floor_width Tiles needed = ceil(floor_area / tile_area) With wastage: tiles_with_waste = ceil(tiles × (1 + wastage% / 100)) Boxes needed = ceil(tiles_with_waste / tiles_per_box)

Practical Tips
- •For diagonal tile laying patterns, increase wastage to 15–20% as more cuts are required at edges.
- •Large-format tiles (800×800 mm and above) require a level sub-floor with maximum deviation of 3 mm in 3 m; hire a specialist layer.
- •Buy 5–10% extra tiles from the same batch — dye-lot differences make it nearly impossible to match tiles from a later purchase.
