Calculation steps

  1. 1Room area: 4 × 3 = 12.00 m²
  2. 2Tile area: 0.8 × 0.8 = 0.640 m² → theoretical 18.7 tiles
  3. 3With 8% waste: ⌈18.7 × 1.08⌉ = 21 tiles
  4. 4Row-layout check: ⌈4/0.8⌉ × ⌈3/0.8⌉ = 5 × 4 = 20 tiles
  5. 5Take the larger of the two: 21 tiles

Waste rate guide

ScenarioSuggested waste
Square room, straight lay5–8%
Diagonal / herringbone lay10–15%
Many corners & pipes10–12%
Large format (≥750×1500)8–12%
Spares for future repair+3–5 tiles
Buy from the same production batch to avoid shade variation (check the batch number on the box). Tiles are sold by box — divide the recommended count by tiles-per-box and round up. Keep 3–5 spare tiles after renovation: identical models may be discontinued within a few years.
