Painting the exterior of your home can give it a fresh, updated look. But before you start, it’s important to estimate how much paint you’ll need. This can help you avoid running out of paint mid-project or buying too much and wasting money. In this article, we’ll share some tips and tricks for estimating exterior paint needed in 2023.

Factors to Consider

Several factors can affect how much paint you’ll need for your exterior painting project. These include:

Surface Area

The size of your home’s exterior is the most obvious factor in determining how much paint you’ll need. Measure the surface area of each wall, and add them together to get the total surface area. You can use online calculators or ask your local paint store for help.

Type of Surface

Different surfaces require different amounts of paint. For example, if you’re painting over a dark color, you may need more paint to achieve full coverage. Similarly, rough or textured surfaces may require extra paint to fill in the crevices.

Type of Paint

The type of paint you choose can also affect how much you’ll need. High-quality paints often provide better coverage with fewer coats, which can save you money in the long run.

Other Factors

Other factors, such as the condition of the surface, weather conditions, and the skill level of the painter, can also affect how much paint you’ll need.

Calculating Paint Needed

Once you’ve considered these factors, you can use a simple formula to estimate how much paint you’ll need: Total surface area ÷ coverage per gallon = gallons of paint needed Most paint cans will list the coverage per gallon on the label. For example, if your total surface area is 1,500 square feet, and the coverage per gallon is 400 square feet, you’ll need: 1,500 ÷ 400 = 3.75 gallons of paint

Buying the Right Amount

It’s always better to have too much paint than not enough, but you don’t want to waste money either. Once you’ve calculated how much paint you need, consider buying an extra quart or two, just in case. You can always use leftover paint for touch-ups or future projects.


Estimating exterior paint needed may seem daunting, but it’s an important step in any painting project. By considering the factors that affect how much paint you’ll need and using a simple formula to calculate it, you can ensure a successful and cost-effective project. Happy painting!
