Bedroom paint calculator
A typical bedroom is 12 × 11 ft with one door and one window. Walls take ~330 sq ft of paint, which works out to a single gallon for a same-color refresh and two gallons for a color change. Eggshell is the default finish — washable enough to wipe handprints off, soft enough to read as quiet at night.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
Recommended finish: eggshell
How much paint for a 12 × 11 bedroom?
About 1 gallon for one coat in the same color, or 2 gallons for two coats over a color change. With Kompozit ONE you can usually get away with one coat on a same-color refresh.
Should I paint the ceiling?
Most bedroom repaints skip the ceiling unless it's yellowed, water-stained, or you're changing the wall color dramatically. A ceiling painted the same off-white as last time will read fine. If you do, plan for ~0.5 gallons of flat ceiling paint.
FAQ
Eggshell. It has a slight sheen that resists fingerprints and wipes clean, but it doesn't look glossy or institutional. Satin is OK if you want more wipeability; flat tends to scuff in higher-traffic bedrooms.
Yes for a one-coat refresh: prep in the morning, paint in the afternoon, sleep in it that night with the windows open. For a color change with two coats, plan two days because you want each coat fully dry.
