Paint & cans
Plan your quantities using your measurements and product label.
Formula & scope
Liters = (surface − openings) × coats ÷ coverage. Read your paint label: coverage varies with product and surface. No automatic touch-up allowance.
Faint examples are hints only and are never used as inputs. Enter your own project values. Results are estimates; check the product label before ordering.
