Coverage Rate
Use manufacturer data
Use the coverage figure printed on the paint container or technical data sheet whenever available.
Paint Quantity & Coverage Tool
Paint Coverage Calculator
Calculate paint required, surface area or coverage rate using known project values and consistent metric or US customary units.
CALCULATED
Real-World Variation
Actual consumption can differ
Surface porosity, texture, application method, overspray, thinning and paint formulation can change real paint consumption.
Scope
Coverage mathematics only
This tool does not calculate room geometry, doors, windows, primer, paint cans or project pricing.
PAINT COVERAGE GUIDE
How to Use the Paint Coverage Calculator
Calculate paint required, surface area or coverage rate using your project values and supported units.
Choose What to Calculate
Select Paint Required, Surface Area or Coverage Rate as the value you want to calculate.
Paint Required · Surface Area · Coverage Rate
Calculate Paint Required
Enter surface area, number of coats and coverage rate to calculate the paint required.
Paint = (Area × Coats) ÷ Coverage
Calculate Surface Area
Enter paint volume, coverage rate and number of coats to calculate surface area.
Area = (Paint × Coverage) ÷ Coats
Calculate Coverage Rate
Enter surface area, paint volume and number of coats to calculate the coverage rate.
Coverage = (Area × Coats) ÷ Paint
Choose Supported Units
Choose area, paint volume and coverage units that match the values you enter.
m² · ft² | mL · L · US gal
Use Manufacturer Coverage Data
Use the coverage rate printed on the paint container or technical data sheet whenever available.
m²/L · ft²/US gal
Use the result as a paint coverage calculation.
Actual paint consumption can vary with surface porosity, texture, application method, overspray, thinning and paint formulation.
