What is Paint Calculator?
Calculates liters or gallons of paint required based on wall area and coverage rate.
Step-by-Step Guide
- Measure Area: Calculate the total square meter/footage of walls (Length x Height).
- Subtract Openings: Deduct area for doors (~2m²) and windows (~1.5m²).
- Check Coverage: Look at your paint can. Standard is 10-12 m²/L.
- Calculate: Divide Net Area by Coverage. Round up to the nearest can.
Example
Input: 50m² Area, 10m²/L Coverage
Result: 5 Liters
