Hallway paint calculator
Hallways are narrow and high-traffic. A typical 4 × 15 ft hall has 304 sq ft of wall area, which is ~1 gallon for two coats. Use satin (not eggshell or flat) — hallway walls take constant abuse from elbows, shoulders, suitcases, and pets, and a slightly more washable finish pays off.
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: satin
Stair-and-hallway combinations
Stair walls are tall and irregular. Measure the highest point (typically 12–18 ft) and use it as the ceiling height in this calculator — you'll over-estimate slightly, which is correct since stair walls have triangular cuts. For a 4 × 8 ft staircase reaching 16 ft tall, plan for ~256 sq ft of wall area.
FAQ
Eggshell is slightly more delicate than satin; flat scuffs in a week. Hallways need cleanability. Satin is the right balance of "looks like wall paint, not bathroom paint" and durability.
