Paint Coverage:
What to Expect from a Gallon?


Painting your home is one of the simplest ways to give it a fresh new look. However, before you embark on this DIY project, it’s important to know how much paint coverage you need to avoid running out of paint or having to make extra trips to the store.


So, how much area can one gallon of paint cover? The answer is that it depends. While 1 gallon of paint can typically cover 350 to 400 square feet with one coat, several factors can impact the actual coverage.


In this article, we’ll explore these factors and explain why hiring a professional painter like Wade Paint Co. is the best way to ensure a beautiful, long-lasting finish.

Factors That Affect Paint Coverage

Poor quality paint

The quality of the paint you choose plays a huge role in determining how well it covers. Going for the cheaper option might seem like a good idea at first, but it could end up costing you more in the long run. When you opt for low-quality paint, you’ll need to apply more coats to achieve the same coverage as you would with high-quality paint. Don’t skimp on quality when it comes to painting, or you might be left with a lackluster finish and extra time and money spent on additional coats.

Uneven application

How you apply the paint can also make a big difference in how well it covers. If you don’t apply the paint evenly, you may end up with areas that need an extra coat or two, which can quickly add up in terms of how much paint you need. Make sure to take your time and apply the paint evenly to avoid having to do extra work and spend more money on additional coats.

Using the wrong tools

The tools you use to apply the paint are also important to consider. Using low-quality brushes or rollers might seem like a way to save a few bucks, but it could end up costing you more in paint in the long run. These tools can create a streaky or textured finish, which will require more paint to achieve a smooth and even look. Invest in high-quality brushes and rollers to avoid any issues with coverage and get the best results possible.

Texture of the wall

If you have rough or porous walls, you may need more time to paint to get the coverage you want. Choosing a thick paint that can fill in all those nooks and crannies is important. That way, you’ll be able to create a smooth, even finish without having to go over the same spot multiple times.

Color of the wall

The color of the wall you’re painting over can play a role in how much paint you’ll need. For instance, if you’re painting a light color over a dark color, you’ll likely need more coats of paint to get the coverage you’re looking for. On the other hand, if you’re painting a dark color over a light color, you may need fewer coats of paint.

Tips for Calculating Paint Needs

To help you plan your next painting project, here are a few tips for calculating your paint needs:

  1. Measure the surface area. Before you can calculate how much paint you’ll need, you’ll need to measure the surface area you’re painting. To do this, simply multiply the length and width of the surface.

  2. Check the paint can. The paint can provide information on the coverage rate and the recommended number of coats. Use this information as a starting point for calculating your paint needs.(1)

  3. Factor in additional coats. If you’re planning to apply more than one coat of paint, be sure to factor that into your calculations. Multiply the surface area by the number of coats you plan to apply to get the total surface area you’ll need to cover.

Frequently Asked Questions

Whether you need to use a primer before painting depends on the surface and the type of paint you’re using. If you’re painting over bare wood or an unpainted surface, primer is usually necessary for a smooth finish. But if you’re painting over a previously painted surface with a similar color, the primer may not be needed. It’s always a good idea to consult with a professional to make sure you’re doing it right.


Painting a room in one day is possible, but it depends on factors such as the room’s size and complexity, the number of coats required, and the painter’s skill level. Smaller and simpler rooms can be completed in a day, but larger or more complex rooms may take longer. It’s essential to take enough time to prepare the room, apply the paint, and allow it to dry properly between coats. Rushing the job can lead to mistakes and an unsatisfactory finish.


The amount of paint you need depends on factors like paint quality, surface texture, and application method. One gallon may be enough for two coats, but sometimes you’ll need more. Consulting with a professional can help you determine how much paint is needed for your project.


To figure out how much paint you need for your 1500-square-foot house, there are a few things to consider, like the number of rooms and coats needed. Typically, one coat takes about 10-12 gallons of paint. However, this can change depending on the details of your project. You can get a better estimate by measuring your space and asking a professional for advice.


It takes time to paint a 12×12 room, and it depends on how good the painter is, how many coats are required, and the prep work needed. Typically, a professional can paint a 12×12 room with one coat of paint in about 4-6 hours. But it may take longer, depending on your project’s details. It’s best to speak with a professional to determine how long your specific project will take.
