Frequently asked questions

How are door and window deductions calculated?

Each door is assumed to take up about 1.8 square meters and each window about 1.4 square meters of wall area, subtracted from the total before calculating paint needed.

What does "coverage" mean?

Coverage is how many square meters one liter of your specific paint covers - check the paint can label, as this varies by brand and paint type.

Should I round up the result?

Yes, paint is typically sold in fixed can sizes, so round up to the nearest can size available and consider buying slightly extra for touch-ups.
