# How Much Paint To Paint House? How To Calculate the Volume and Cost

When it comes time to repaint your home, it’s a little more complicated than grabbing a bucket, tossing in a few drops of paint, and going to town.

You can damage your home and bank account if you don’t calculate the right volume of paint or how much you’ll spend. It’s not hard once you know the average cost per gallon and how to match the coverage of paint with your home.

So, if you want to learn how to properly figure out how much paint to paint the house, just keep reading.

## How Much Paint to Paint House on Average?

The amount of paint needed for a house will depend on the size of the house, the type of paint used, and the number of coats needed. Generally speaking, the average house requires between two to five gallons of paint. One gallon of paint covers approximately 400 square feet.

When painting a two-story house, you may need up to two gallons per 10′ x 10′ section. You may need to add a gallon of three-coat paint for each coat. Furthermore, if you are painting over a darker color, you may need more coats, which can increase the amount of paint needed.

## How to Calculate the Volume and Cost?

To calculate the amount of paint needed to paint a house, you’ll need to determine the total surface area that requires painting and the paint coverage per unit area. Here’s a step-by-step guide on how to calculate the volume of paint and the cost:

### Measure the Surface Area

Measure the house’s exterior walls to get the total surface area that needs painting. Measure the height and width of each wall, then multiply them together to get the area of each wall.

Add up the areas of all the walls to get the total surface area.

### Calculate the Volume of Paint Needed

Divide the total surface area by the paint coverage per unit area to get the volume of paint needed. If the paint coverage is in square feet per gallon, divide the total surface area (in square feet) by the paint coverage (in square feet per gallon).

If the paint coverage is in square meters per liter, divide the total surface area (in square meters) by the paint coverage (in square meters per liter).

### Account for Multiple Coats

If you plan to apply multiple coats of paint, multiply the volume of paint needed by the number of coats you intend to apply. To calculate the cost, multiply the total volume of paint (in gallons or liters) by the cost per gallon or liter of the paint.

Keep in mind that this is an estimation, and actual paint usage may vary based on factors such as the texture of the surface, the condition of the walls, and the application method.
