How this estimate is calculated
- Wall area subtracts doors and windows. A standard door is counted as 1.6 m² and a window as 1.44 m², so the total comes out close to what you'll actually paint.
- Coverage varies by wall and paint. Rougher or more porous walls, and darker colour changes, often use more paint than the tin's stated coverage.
- Litres round up to the nearest half. You can't buy exactly what a formula tells you, so the figure matches what you'd actually purchase.
- Calculated in your browser. Your measurements and prices are used locally to produce this estimate. If you choose to send a quote request, your estimate and selected answers are included in that request. Read our Privacy Policy for how requests and website usage information are handled.
These are planning estimates, not quotes or an original market survey. See Sources and methodology for assumptions, limitations and research references.
