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.
The Materio app for Android uses the same formula. The site's engine is a 1:1 port of the app's code.
