House Paint Calculator (Exterior)
How to Use the House Paint Calculator
To use this calculator, simply enter the length, width, and height of your house in feet. Enter the number of doors and windows to be excluded from the painting, and specify the coverage of the paint you plan to use in square feet per gallon. Click the “Calculate” button to determine the total amount of paint needed in gallons.
Explanation of the Calculation
The calculator computes the total exterior wall area based on the provided dimensions. It then subtracts the area taken up by doors and windows to find the net paintable area. Finally, it divides this net area by the paint coverage to provide the quantity of paint needed in gallons.
Limitations
This calculator assumes standard door and window sizes and does not account for additional architectural features such as overhangs or decorative trims. Please adjust the calculated result if such features are present in your house.
