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 10 × 10 ft room needs
A 10 × 10 ft room is a compact bedroom, office, or utility space where a paint job is usually one gallon of paint per coat plus a primer. The small footprint makes prep, not quantity, the part that takes the most time.
How to decide
At this size, the practical question is coverage assumptions: paint brands commonly list 350–400 sq ft per gallon per coat, but texture, color change, and application method change real coverage. The calculator uses a 350 sq ft per gallon reference with two coats; verify the can label and subtract windows and doors before buying.
Checks before you buy
- Subtract doors, windows, and any pre-painted trim from the wall area.
- Check the can's listed coverage, since 350 and 400 sq ft per gallon are both common.
- Buy a small extra for touch-ups rather than finishing the job short.
