Paint Calculator
Estimate paint required from the surface dimensions and the manufacturer’s stated coverage rate.
Estimated result—
How it works
Area = length × height. Litres = area ÷ coverage per litre.
Example
A 6 m × 2.4 m wall is 14.4 m². At 12 m²/L, one coat needs about 1.2 litres before wastage.
Useful things to know
- Multiply the result by the number of coats you plan to apply.
- Subtract large doors and windows if you need a tighter estimate.
- Texture, porosity and application method can reduce real-world coverage.
