Paint Coverage Calculator

Formula

To calculate the total paint needed:

\[ \text{Total Paint Needed} = \frac{\text{Wall Area} \times \text{Number of Coats}}{\text{Coverage per Gallon}} \]

Where:

\(\text{Total Paint Needed}\) is the amount of paint required in gallons
Wall Area is the total area to be painted in square feet (sq ft)
Coverage per Gallon is the coverage provided by one gallon of paint in square feet (sq ft)
Number of Coats is the number of coats of paint to be applied

What is Paint Coverage?

Paint coverage refers to the area that a specific amount of paint can cover. It is usually measured in square feet per gallon and depends on factors like the type of paint, surface texture, and application method[^1^][^2^].

Example Calculation

Let's assume the following values:

Wall Area = 800 sq ft
Coverage per Gallon = 350 sq ft
Number of Coats = 2

Using the formula:

\[ \text{Total Paint Needed} = \frac{800 \times 2}{350} \approx 4.57 \text{ gallons} \]

The total paint needed is approximately 4.57 gallons.
