Gallons Needed vs Coverage Rate
How to Calculate Paint Coverage
Formula
Gallons = (Area × Number of Coats) / Coverage Rate
Standard interior latex paint covers approximately 350-400 sq ft per gallon. Factors that reduce coverage include rough or textured surfaces, porous substrates, and dark-to-light color changes.
Example Calculation
Painting 400 sq ft of wall area with 2 coats at 350 sq ft/gallon.
- 01Total coverage = 400 × 2 = 800 sq ft
- 02Gallons = 800 / 350 = 2.29 → 3 gallons
