Calculating the amount of paint needed for an exterior project can save you time and money. Whether you’re painting a house, a fence, or any other outdoor structure, knowing how much paint to buy is essential. This calculator helps you determine the total gallons of paint required based on the dimensions of the area you plan to paint.
Understanding Paint Coverage
Paint coverage refers to the area that a gallon of paint can cover. This can vary based on the type of paint, the surface texture, and the application method. On average, one gallon of paint covers about 350 to 400 square feet for a single coat. However,
How to Use the Paint Calculator
Using the exterior paint calculator is straightforward. Here are the steps:
- Measure the length and height of the wall or surface you intend to paint. Multiply these two measurements to get the total area in square feet.
- Decide how many coats of paint you will apply. This is important because each coat will require additional paint.
- Check the paint can for the coverage information, which tells you how many square feet one gallon of paint will cover.
- Input these values into the calculator to determine the total gallons of paint needed.
Example Calculation
Let’s say you have a wall that is 20 feet long and 10 feet high. You plan to apply two coats of paint, and the paint you are using covers 350 square feet per gallon. Here’s how you would calculate the total gallons needed:
1. Calculate the area: 20 ft (length) x 10 ft (height) = 200 sq ft.
2. Since you are applying two coats, multiply the area by 2: 200 sq ft x 2 = 400 sq ft.
3. Now, divide the total area by the coverage: 400 sq ft / 350 sq ft per gallon = 1.14 gallons.
In this case, you would need to purchase at least 2 gallons of paint to ensure you have enough for your project.
Why Accurate Calculations Matter
Accurate calculations are crucial for several reasons:
- Cost Efficiency: Buying the right amount of paint helps you avoid overspending on excess paint that you may not use.
- Time Savings: Having the correct amount of paint on hand means you won’t have to make last-minute trips to the store.
- Quality Finish: Applying the correct number of coats ensures a uniform finish and better durability of the paint job.

Common Questions About Exterior Painting
1. How do I prepare the surface before painting?
Preparation is key to a successful paint job. Start by cleaning the surface to remove dirt, dust, and any loose paint. If there are any cracks or holes, fill them with a suitable filler. Sand the surface to create a smooth finish, and if necessary, apply a primer to help the paint adhere better.
2. What type of paint should I use for exterior surfaces?
For exterior surfaces, it’s best to use high-quality exterior paint that is designed to withstand weather conditions. Look for paint that is mildew-resistant and has UV protection to prevent fading. Latex paints are commonly used for their durability and ease of cleaning.
3. How long does exterior paint last?
The lifespan of exterior paint can vary based on several factors, including the type of paint used, the surface it’s applied to, and the local climate. Generally, high-quality exterior paint can last anywhere from 5 to 10 years before needing a repaint.
4. Can I paint over old paint?
Yes, you can paint over old paint, but it’s important to ensure that the old paint is in good condition. If the old paint is peeling or flaking, it should be removed. If the surface is smooth and well-adhered, you can apply a new coat of paint directly over it, but using a primer can help improve adhesion.
5. What is the best time of year to paint the exterior of my house?
The best time to paint the exterior of your house is during mild weather conditions, typically in spring or fall. Avoid painting in extreme temperatures, high humidity, or direct sunlight, as these conditions can affect the paint’s application and drying time.
