Coverage is about 350 sq ft per gallon per coat for most interior paint — check the can.
Bare drywall, patches, and big colour changes soak up more, so prime first and consider an
extra coat.
Adjust for your room
Subtract big windows and doors, add the ceiling if you're painting it, and bump to three coats for a strong colour change. Prime bare or patched walls first so two coats is enough.
Coverage ≈ 350 sq ft/gal at 8 ft walls, 2 coats. Estimates only.
What a 12 × 14 ft room needs
A 12 × 14 ft room is a medium bedroom or family room. With an 8 ft ceiling, the walls and ceiling together paint out to roughly two gallons of paint per coat, which makes the project a comfortable weekend job with prep time included.
How to decide
At this size, decide whether the ceiling is part of the same color scheme and count it separately in the area. The calculator totals walls plus the ceiling at 350 sq ft per gallon and two coats; confirm your paint's coverage and whether the room needs primer before the first coat.
Checks before you buy
- Decide on ceiling treatment before calculating so the total area is right.
- Verify coverage on the can; darker or flatter finishes may need more coats.
- Allow drying time between coats, especially in humid conditions.
