Our tool quickly calculates the square footage needed for your paint project.

## Square Footage Calculator for Paint

This calculator helps you estimate the amount of paint you’ll need to cover the walls of a room, considering the dimensions of the room and the number of doors and windows.

### Instructions:

- Enter the length, width, and height of the room in feet.
- Enter the number of doors and windows in the room.
- Enter the coverage area per gallon of paint.
- Click the “Calculate” button to get the results.

### How It Works:

The calculator performs the following steps to determine the amount of paint needed:

- Calculates the total wall area by adding the areas of all four walls.
- Subtracts the area occupied by doors and windows from the total wall area.
- Divides the paintable area by the coverage area per gallon to determine the total number of gallons of paint required, rounding up to ensure you have enough paint.

### Limitations:

The results are an estimate and can vary based on various factors such as paint type, wall texture, and application method. It’s always a good idea to have a little extra paint to account for these variables.
