Wall paint for an 8×10 room by ceiling height
Two coats, 350 sq ft per gallon, one door and two windows subtracted.
| Ceiling height | Wall area | Exact paint | Buy |
|---|---|---|---|
| 8 ft | 237 sq ft | 1.35 gal | 1 gallon + 2 quarts |
| 9 ft | 273 sq ft | 1.56 gal | 2 gallons |
| 10 ft | 309 sq ft | 1.77 gal | 2 gallons |
Ceiling paint
The ceiling is 80 sq ft. One coat needs 1 quart; two coats need 2 quarts. Flat ceiling paint hides imperfections best.
Buying for this room
Walls and ceiling together come to about 1.8 gallons, so single gallons and quarts are the right size. If you plan to paint other rooms the same color, a 5-gallon bucket may still be the better buy. Need primer for new drywall or a big color change? Plan on 1 gallon for the walls.
