The exterior of your home is a reflection of you and your unique style. What better way to make it look beautiful, than to paint it with the perfect color and coverage? Picking the right color is the fun part, but how do you know how much paint you’ll need? A perimeter calculator for painting can help you estimate the right amount of paint for your home’s exterior, so you don’t end up with too little or too much.

Here’s how it works. First, measure the perimeter of the area that needs to be painted. This includes all flat areas and any wainscotting or trim. You can do this with a handy measuring tape or laser measuring device. Once you have all of your measurements, add them up and multiply the total by 2. This will give you the total square footage of the area that needs to be painted.

Next, you need to figure out the coverage of the paint you’ll be using. Most paints have a coverage rate of 400-450 square feet per gallon. This means that one gallon of paint should cover 400-450 square feet of surface area. Taking your total square footage from the previous step, divide this number by the coverage rate of the paint to get the total number of gallons of paint you’ll need to complete your project.

Finally, make sure to account for any winds or additional coats that may be necessary. It’s always better to have a bit of extra paint on hand, just in case. To round up your final number of gallons, divide your total square footage by the coverage rate of the paint, then add 1 more gallon of paint to account for waste and areas that may need a second coat.

Using a perimeter calculator for painting can help you make sure that you have the right amount of paint for your home’s exterior. This will save you time, energy, and money, so you can get the job done right the first time.
