Typically, a standard-sized exterior door requires about one quart of paint to cover it completely. However, this can vary depending on the type of paint you choose and the door's surface material. For instance, if you’re using a thicker paint or working with a textured surface, you may need slightly more.Before you start, be sure to prepare your door properly by cleaning it and applying a primer if necessary. This will ensure better adhesion and a more vibrant finish. Let’s dive into some calculation tips to help you determine the right amount of paint for your exterior door!Calculating Paint Needed for Your Exterior DoorTo calculate the amount of paint required, you first need to measure the door. A standard exterior door is approximately 80 inches tall and 36 inches wide. Multiply these dimensions to get the total square footage: 80 x 36 = 288 square inches, or about 20 square feet. Most paint covers about 350 square feet per gallon. So, dividing your total square feet by the coverage per gallon gives you the amount of paint needed. For one coat, you would need about 1/10 of a gallon, which is about 1 quart for a solid color.If you're planning to apply two coats for a more durable finish, simply multiply your total by two. Remember to factor in extra paint for touch-ups or if your door has intricate designs that require more detail work. This simple calculation can save you from running back to the store!Considerations for Different Paint TypesThe type of paint you choose can also affect how much you need. Latex paints typically cover better and dry faster than oil-based paints, so you might find that you need less of them for your exterior door.Also, if you are painting a door with a glossy finish, it may require a little more paint than a flat finish due to its smooth texture. Always check the paint can for specific guidelines regarding coverage and application.Lastly, don't forget to consider the color! Dark colors may require an additional coat over light-colored primers, which could alter your paint quantity needs.FAQWhat type of paint is best for exterior doors?For exterior doors, a high-quality exterior latex paint is recommended for its durability and weather resistance.
