Paint Calculator — Free Online Calculator

Estimates the amount of paint needed to cover walls and ceilings.

What is it?

The paint calculator estimates how many litres of paint you need to cover walls or a ceiling, based on net area, product coverage rate, and number of coats.

Formula

Paint needed (L) = (Net area × Coats) / Coverage (m²/L) Round up to nearest can size

Example

Net wall area 46 m², 2 coats, coverage 10 m²/L. Paint = (46 × 2) / 10 = 9.2 L. Buy three 3.5 L cans (10.5 L).
