What this includes
Total liters = (area × coats ÷ coverage) × (1 + waste%).
This is an estimate. Surface texture and absorbency can change coverage.

Tips for better estimates
- Subtract large windows/doors if you want a tighter estimate.
- Rough surfaces often need more paint.
- Add extra for touch-ups and edges.
Check the can. Common values are around 8–12 m²/L depending on paint type and surface.
Often yes when changing color drastically or on new drywall/wood. Primer changes consumption.
Roller loading, edges, and surface texture usually increase paint use versus ideal math.
