Wall paint calculator
Painting one wall — an accent wall, a single feature wall, or a partial repaint? Just length and height, no perimeter math. Common case: a quart of accent color is enough for one full wall up to ~150 sq ft.
Estimates round up to the nearest quart and are based on Kompozit's published coverage. Buy slightly more for touch-ups and color changes.
A quart usually does it
A typical accent wall (12 ft wide × 9 ft tall = 108 sq ft) needs about 0.6 gallons for two coats — well under a quart per coat. Buy a quart of your accent color; you'll have plenty for touch-ups. Only step up to a gallon if your wall is over 150 sq ft.
Deep colors need 3 coats
Saturated reds, blues, greens, and any "moody" deep accent color almost always need three coats over a previously light wall — even with the right primer underneath. Plan for a quart per coat in case the third coat gets thirsty.
FAQ
If you're going light-on-light, no. If you're going dark-on-light or vice versa, tint a primer (PRIME) toward the accent color first — you'll save a coat and end up with truer color. For very deep colors, the primer step is the difference between three coats looking right and four coats looking patchy.
Same finish as the rest of the room — eggshell or satin. Mixing finishes on adjacent walls makes the accent look like a mistake. Color is the accent, not sheen.
Color blocking — painting the lower 4 ft of a wall in a different color — works if the line is intentional and clean. Pre-tape with delicate tape, paint the accent first, then the upper color on top of the tape edge. Calculate paint as if you're doing each section as its own area.
