Tiles, panels, porcelain

Area + waste → whole boxes.

How we calculate it

What you enter

  • Area (m²)
  • Pack coverage (m²)
  • Waste (%)

Formula

required = Area × (1 + Waste ÷ 100)
packs = ⌈ required ÷ Pack coverage ⌉
actual waste = (packs × Pack coverage − Area) ÷ (packs × Pack coverage) × 100%

Example

The default values from the form, run through the same engine:

To buy
15 packs
Waste7.4%

What to watch out for

A 5–7% allowance is enough for a straight layout. Large format, diagonal or brick-bond layouts need 10–15%. Buy from a single batch.
