eng.paint-coverage Calculator
Calculates the number of paint cans required for a surface area from coverage rate and number of coats, with waste factor. Paint coverage rates vary from 350–450 sf/gallon for trim to 250–350 sf/gallon for textured surfaces — thinning reduces coverage.
Inputs
Room Length M
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Room Width M
Horizontal extent perpendicular to the length.
Ceiling Height M
Vertical measurement. For health calculators, typically standing height without shoes.
Doors Windows
Count of items or occurrences.
Coats
Count of items or occurrences.
Coverage M2 L
Age in completed years. Many health and fitness formulas adjust for age.
Results
paint needed (liters)
Sample size or count used in the calculation.
paint needed (gallons)
Sample size or count used in the calculation.
wall area (m²)
The computed two-dimensional surface area.
ceiling area (m²)
The computed two-dimensional surface area.
total area with coats (m²)
The combined total across all inputs and components.
coverage rate
The fraction of the total that is protected, tested, or accounted for. Higher coverage reduces risk of gaps.
