What You'll Learn
One gallon covers 250-400 sq ft
When planning a painting project, it's important to know how much paint you'll need. Behr paint typically covers 250-400 sq ft per gallon, but this can vary depending on several factors.
The amount of paint needed depends on the surface being painted. Porous, rough, or textured surfaces will generally require more paint, as will surfaces that are being painted for the first time. If you're using a deep, intense colour, you may need multiple coats or a tinted primer for the best results. On the other hand, if you're painting a smooth, primed, or sealed surface, or making a subtle colour change, you may need less paint. It's also worth considering the number of ""unpaintable" features on the surface, such as windows and doors, as these will reduce the overall square footage that needs to be covered.
To estimate the amount of paint needed for a project, you can use Behr's paint calculator tool or follow some simple steps. First, determine the size of the surface by measuring its perimeter and height. Then, multiply the perimeter by the height to get the total square footage. Don't forget to subtract the areas of any doors and windows, which typically average 15 square feet and 20 square feet, respectively. If you're painting trim, multiply the total trim length by 0.5 feet to get the square footage, as the average trim width is six inches. For gutters, one linear foot is equivalent to one square foot.
By considering the unique characteristics of your project and using the appropriate calculation methods, you can accurately estimate how much Behr paint you'll need, ensuring a successful painting experience.

More paint needed for rough surfaces
One gallon of Behr paint can cover between 250 to 400 square feet of surface area with one coat. However, this range serves only as an estimate, as the amount of paint needed depends on several factors. A porous, rough, textured, or previously unpainted surface will generally require more paint. This is because rough surfaces have protrusions and divots that allow dirt, dust, and cobwebs to accumulate, necessitating deeper cleaning and added pressure to reach every crevice and remove debris. For exterior surfaces, pressure washing is recommended to effectively remove dirt and dust. Interior surfaces, on the other hand, require thorough vacuuming, scrubbing with a cleaning solution, and careful handling to avoid surface damage.
Additionally, the type of paint used influences coverage. Behr's stain-blocking paint and primer offer advanced scuff and mar resistance, requiring fewer coats and covering up to 400 square feet per gallon. The BEHR DYNASTY™ & MARQUEE® Interior & Exterior One-Coat Hide Color Collection also promises one-coat coverage of up to 400 square feet per gallon.
The colour of the paint is another factor to consider. Choosing a deep and intense colour may require multiple coats or even a tinted primer for optimal results. In contrast, a subtle colour change may reduce the amount of paint needed. The presence of "unpaintable" features, such as windows and doors, further contributes to decreased paint requirements.
To estimate the amount of paint needed for a project, it is essential to measure the surface area accurately. For exterior projects, measure the perimeter of the house and its height from the foundation to the roofline, excluding gables. Multiply the perimeter by the height and subtract the areas of doors and windows for a more precise calculation. For interior projects, measure the perimeter and height of the room, then multiply these values together before subtracting the areas of doors and windows.
Furthermore, trim and gutter calculations are crucial for determining additional paint requirements. Measure the total length of the trim and multiply it by 0.5 feet to estimate the square footage. Similarly, calculate the total length of the gutter, keeping in mind that one linear foot of gutter approximates one square foot.
While these calculations provide a good estimate, it is worth noting that every project is unique. Surface preparation is vital, and different types of siding may call for a tailored approach. Consulting Behr's paint calculator or seeking assistance from Behr Technical Experts can also help ensure you have the right amount of paint for your project.

Primer: 200-300 sq ft per gallon
When it comes to painting, knowing the right amount of paint needed for your project is essential. Behr's range of paints and primers offers a variety of coverage options, with their primers being particularly notable for their efficiency.
The coverage provided by a gallon of paint is a crucial factor in determining the quantity required for a specific project. Behr primers, in particular, offer an impressive range of 200-300 square feet of coverage per gallon. This means that a single gallon of Behr primer has the capacity to cover an area of 200 to 300 square feet with just one coat. This coverage estimate is based on the assumption of a smooth, primed, or sealed surface and a subtle colour change.
It's important to note that the coverage provided by paint can vary depending on factors such as surface texture, porosity, and the desired colour change. For instance, a porous, rough, or previously unpainted surface may require additional paint to ensure adequate coverage. Similarly, if you're planning a dramatic colour change, you may need to apply multiple coats, which will increase the amount of paint needed.
Behr's primer range is designed to provide a durable base coat for subsequent paint applications. By using a primer, you can enhance the adhesion, coverage, and overall finish of your chosen paint colour. It's worth mentioning that Behr offers a range of primers, including those that are stain-blocking, scuff-resistant, and fast-drying, ensuring that you can find the right product for your specific project needs.
When planning your painting project, it's always advisable to refer to the paint manufacturer's guidelines and recommendations. Behr provides helpful resources, such as a paint calculator, to assist you in determining the precise amount of paint required. By taking the time to calculate your needs accurately, you can ensure that your project stays within budget and avoids unnecessary waste.

Trim and gutter paint calculations
When it comes to trim and gutter paint calculations, there are a few things to keep in mind. Firstly, it's important to understand the coverage of a gallon of Behr paint. Typically, one gallon of Behr paint is enough to cover between 250 to 400 square feet of surface area with one coat. However, this range may vary depending on the specific paint product and the surface being painted.
Now, for trim painting, you'll need to estimate the total length of the trim. This includes the baseboard, door, window, and molding trim. The average trim width is usually around six inches, so you can multiply the total trim length by 0.5 feet to get a square footage estimate for the trim. For instance, if the total length of the trim is 40 feet, you'll need enough paint to cover 20 square feet.
As for gutters, the calculation is relatively straightforward. Determine the total linear length of the gutter, and that will approximate the square footage. So, if you have 20 feet of gutter, you'll need paint for 20 square feet.
Once you have the square footage for both the trim and the gutter, you can add those numbers together to get the total additional paint you'll need. It's worth noting that Behr recommends one gallon of paint for trim and gutters for every eight gallons of body paint. This can serve as a helpful rule of thumb.
