Example Scenario
Imagine you want to paint a single room with the following details:
- Wall length: 12 ft
- Wall width: 10 ft
- Wall height: 8 ft
- Include ceiling: Yes
- Paint type: Premium (400 sq ft/gal)
- Number of coats: 2
- Price per gallon: $40
The Paint Gallon Calculator will:
- Calculate wall area: 2×(12+10)×8=352 sq ft
- Include ceiling: 12×10=120 sq ft
- Total area: 352 + 120 = 472 sq ft
- Total coverage for 2 coats: 472×2=944 sq ft
- Gallons needed: 944/400=2.36≈3 gallons
- Total cost: 3 × $40 = $120
The tool also provides leftover paint information, potential savings if buying quarts, and a shopping list including an extra 10% for touch-ups.
