How much paint do I need for a 10x10 room: Estimating the right amount of paint for your small spaceLysander GraySep 02, 2025Table of ContentsTips 1:FAQTable of ContentsTips 1FAQFree Smart Home PlannerAI-Powered smart home design software 2025Home Design for FreeWhen it comes to painting a small room, like a 10x10 space, knowing how much paint you need can save you both time and money. First, you need to calculate the total area of the walls you intend to paint. For a 10x10 room with an 8-foot ceiling, you have four walls to consider. The formula for the area of a wall is height multiplied by width. In this case, each wall is 10 feet wide and 8 feet tall, which gives us 80 square feet per wall. Since there are four walls, you will multiply 80 square feet by 4, totaling 320 square feet of wall space. However, you must subtract the area of windows and doors in the room. For example, if your room has one standard door (about 21 square feet) and one window (about 15 square feet), you would subtract these areas from the total wall area: 320 square feet - 21 square feet (door) - 15 square feet (window) = 284 square feet of paintable wall space. Next, understanding how much paint is required per square foot will help you further. A gallon of paint typically covers about 350-400 square feet. Therefore, if you have 284 square feet of area to paint, you would only need a little less than one gallon of paint. It’s always a good idea to purchase an extra quart to account for touch-ups and any unforeseen issues during the painting process. So, for a 10x10 room, one gallon should suffice, with the extra quart serving as a safety net. Also, consider the type of paint finish you choose, as some finishes may require more coats. A flat finish might need two coats for even coverage, while a satin or semi-gloss finish may cover better in one coat, depending on the color and quality of the paint. Lastly, ensure your supplies are ready before starting the project. You’ll need brushes, rollers, painter’s tape, drop cloths, and a paint tray, in addition to your chosen paint. By preparing ahead of time and knowing how much paint you need, you can make the painting process smooth and enjoyable. Remember to take your time, allow for drying between coats, and enjoy the transformation of your 10x10 room!
