The answer can vary based on a few factors, including the type of paint, the surface texture, and the color you choose. On average, one gallon of paint covers approximately 350 to 400 square feet. However, this can differ if you're painting textured surfaces or using a darker color that requires more coats.Factors Affecting Paint CoverageSeveral factors influence how much paint you need. For instance, the texture of your walls plays a crucial role. Smooth walls will require less paint than rough surfaces. Additionally, if you're switching from a light color to a dark one, you may need an extra coat, which also affects the amount of paint required.Calculating the Right Amount of PaintTo get a more accurate estimate, measure the total square footage of the area you plan to paint. Then, divide this by the coverage of your paint.
