🎨 Paint Calculator

Estimate paint required for your project

Coverage per Liter (m²/L)

Number of Coats

Wall Ceiling Door/Window

Total Paint Required: 0 liters

Total Area: 0 m²

Coats: 2

Total Paint = (Σ(Surface Area × Surface Type) × Coats) / Coverage - Wall: 100% area - Ceiling: 50% area - Doors/Windows: 0% area

📝 Calculation Methodology

Paint requirements are calculated using:

(Total Surface Area × Number of Coats) ÷ Coverage Rate

Key Considerations:

• Wall surfaces count at 100% area
• Ceilings count at 50% area
• Doors/windows subtracted from total
• Standard coverage: 10m² per liter (1 coat)

Provides professional estimates (±15% variance) considering:

• Surface porosity
• Paint viscosity
• Application method
• Environmental factors

▸ Why different surface types?

Different surfaces require different preparation:

Surface	Consideration
Walls	Full coverage
Ceilings	50% harder access
Doors/Windows	Subtract from total

▸ How should I handle irregular shapes?

For non-rectangular areas:

1. Break into rectangular sections
2. Calculate each separately
