Paint Coverage Calculator

Calculate paint needed. Walls, ceilings, trim, exterior.

⚠️ Important: Coverage varies by surface texture, paint type, and application method. Always buy extra for touch-ups. Porous surfaces need more paint. Verify coverage rates on product labels. This estimates based on typical premium paints at manufacturer specs.

💡 Painting Tips

Coverage varies: Porous surfaces (bare drywall, render) use more paint
Dark to light: May need 3 coats or tinted primer
Temperature: Paint in 10-30°C, avoid direct sun or rain forecast
Prep critical: Clean, dry, sanded surfaces = better finish & coverage
Quality matters: Premium paint covers better, lasts longer, fewer coats
Buy extra: Get 10-15% extra for touch-ups, hard to match later
