The formula
Tiles before allowance = area (m²) ÷ tile area (m²). Add cutting allowance and round up. Boxes = required tiles ÷ tiles per box, rounded up.

How this calculator works
Worked example
A 3 m × 2 m wall needs 6 m² of tiles. With 300 × 600 mm tiles, each tile covers 0.18 m² before joints and wastage.
Check before ordering
This is an area-based estimate. Pattern direction, joints, niches, edge cuts and breakages can change the actual requirement. Adhesive, grout, waterproofing and trim depend on your selected products and are not included.
