This tool helps you quickly estimate the cost of painting your house.

## How to Use the House Painting Estimate Calculator

This calculator provides an estimate for the cost of painting the exterior of a house. To use the calculator, fill in all the required fields:

**Length of the House (feet):**Length of one side of the house.**Width of the House (feet):**Width of the adjacent side of the house.**Height of the House (feet):**Height from the ground to the eaves.**Number of Windows:**Total number of windows in the house.**Number of Doors:**Total number of doors in the house.**Cost of Paint per Gallon (USD):**The price of one gallon of paint.**Number of Coats:**Total number of paint coats required.

## How it Calculates the Results

The calculator measures the total wall area using the provided dimensions, then subtracts the area covered by windows and doors to get the total paintable area. It then divides this area by the coverage provided by a gallon of paint (350 sq ft per gallon) to determine the amount of paint needed per coat. By multiplying the per-coat amount by the number of coats and the paint price per gallon, it computes the total paint cost.

## Limitations

Please note, this calculator assumes the following:

- Windows have a fixed size of 15 square feet each.
- Doors have a fixed size of 20 square feet each.
- Paint coverage is uniform at 350 square feet per gallon.
- Rounded values and estimates may differ from real-world conditions.

Always consult with a professional for a more accurate estimate and consider factors such as paint type, surface condition, and additional materials needed.
