Estimate paint quantity from wall area, coats, and coverage.
Quick planning, rough comparisons, and checking whether your assumptions are in the right range before you rely on final quotes or advice.
Review the assumptions below, then compare with related calculators if your decision depends on rates, eligibility, or provider-specific rules.
How this calculator works
- Net area subtracts openings from total wall area.
- Paint volume equals net area times coats divided by coverage rate.
- A small extra margin is useful for touch-ups.
Worked example
An 80 sq m wall area with 8 sq m of openings and two coats needs a bit over 14 litres at 10 sq m per litre.
Important assumptions
- Coverage varies by paint brand and wall texture.
- Primer or multiple colors can change the requirement.
