Porcelain Stoneware Calculator

How to use it

1. Calculate boxes without waste: 30m² ÷ 1.44m²/box = 20.83 → 21 boxes
2. Apply 5-8% waste (porcelain has less waste): 21 x 1.08 = 22.68 → 23 boxes
3. Verify total m²: 23 boxes x 1.44m² = 33.12m²
4. Recommend 1-2 extra boxes for future repairs

Common mistakes

• ⚠️ Not using special adhesive for porcelain (not regular mortar)
• ⚠️ Cutting porcelain without proper tool (fractures easily)
• ⚠️ Not leaving expansion joints on large surfaces

Worked example

Calculate boxes of porcelain tiles for 30m² (boxes of 1.44m², 60x60cm format).

For {area} m²: {cajas_ud} boxes needed. Total: {cajas_ud} boxes ({area_merma_m2} m² with waste).
