Paint project planner
Measure a room and get wall/ceiling area, gallons, cost and next steps.
Enter your room dimensions to see wall/ceiling area, gallons and a cost range.
How to use the paint planner
Enter the room length, width and ceiling height. The planner subtracts doors and windows, then estimates gallons and a cost range based on quality and your state.
What affects how much paint you need
- Wall area (perimeter × height) minus doors and windows.
- Whether you're painting the ceiling.
- The number of coats.
- Whether you use primer.
Coverage
One gallon typically covers ~350 sq ft per coat. Apply on walls after repair and priming for the best result.
These estimates are based on state-level averages, not ZIP-level precision. The final cost varies with your home and local market.
