Calculate tile requirements

Calculate tile requirements: Number of tiles with offcuts

Calculate how many tiles you need for your project - with offcuts and package calculation:

• Area calculation: Length × width in m²
• Tile size: e.g. 30×30cm, 60×60cm, 30×60cm
• Cuts: 5-15% depending on the installation method
• Package conversion: How many packages to buy
?
• Special surfaces: stairs, niches, slopes

Cutting factors:

• Even dressing: 5% waste
• Diagonal laying: 10-15% waste
• Small-part tiles: +5%
• Angled rooms: +10%

Example: Bathroom 6m², tile 30×30cm (0.09m²), diagonal laying: 6 m² × 1.15 (offcut) = 6.9m². Tiles: 6.9 / 0.09 = 76.7 → 77 tiles. At 10 pieces/package = 8 packages.

Tip: Keep 10% in reserve for later repairs. Buy the same batch (color differences!).
