Start by measuring the room's length, width, and height. Multiply these measurements to get the total area in square meters. If math isn't your favorite part, many online paint calculators can do the work for you-just enter your numbers, and they'll answer. For walls, measure each wall's width and height, multiply these, and add them together. If your room is around 50 square meters, and each liter of paint covers about 10 square meters, you'll need roughly five liters for one coat. Since most rooms look best with two coats, double that to get a smooth, lasting finish. Remember the ceiling, too! Measure its length and width, add that area to your total, and you're covered. If you're only painting one wall, it's even simpler: measure the width and height, multiply, and you'll know the exact area to cover. To avoid overbuying, take any large doors and windows into account. Measure their height and width, subtract these from your total, and you're set. And if you're freshening up doors, skirting, or radiators, consider using an eggshell or similar durable finish, as it's designed to handle daily use. I recommend you round up a little on your paint order. It's better to have a bit extra than to fall short, and many suppliers offer options to return or recycle leftovers. Just gather your measurements, get your paint, and you'll be ready to go.
For first-time DIYers, one gallon of paint typically covers 350 to 400 square feet. Measure your walls, divide the total square footage by that number, and you'll know how many gallons to buy. Textured walls or darker colors might need more, while smoother surfaces or lighter colors need less. To avoid overbuying, get an extra quart for touch-ups instead of a full gallon.
When calculating the right amount of paint for a project, I always recommend working closely with a professional painter. Typically, one gallon covers about 350 square feet, but factors like the type of surface and whether you're making a significant color change may require additional coats. A professional can help assess the surface area, texture, and condition of your walls, which all impact how much paint you'll need. I also recommend buying slightly more than your estimate-usually an additional quart per room for touch-ups. This ensures you won't run out mid-project while avoiding unnecessary excess.
Measuring the walls and areas being painted is the best way to determine the right amount. The typical paint can will cover 300-400 square feet. I like to be conservative and estimate at 300 square feet then buy the closest amount exactly with no buffer. You can always go back to get more paint and it is more difficult to return unused paint.
