Interior Room Painting Coverage Calculation
Practical step-by-step numerical demonstration with real-world parameters

Painting a standard 12 ft ร— 15 ft room with 9 ft ceilings, including two coats of premium acrylic paint.

Baseline Inputs

Perimeter & Ceiling Height:

54 linear ft ร— 9 ft height

Gross Wall Area:

486 sq ft

Deductions (2 Doors, 2 Windows):

-60 sq ft

Computed Benchmarks

Net Wall Surface Area:

426 sq ft

Paint Required (Two Coats):

2.43 Gallons (Order 3 Gallons)

Takeaway & Analysis: One gallon of interior paint reliably covers 350 to 400 square feet on primed drywall. Ordering 3 gallons ensures adequate supply for touch-ups.
