Behr interior lines and coverage

Behr sells several interior lines at Home Depot. Premium lines like Marquee and Dynasty are formulated for better hide, so a dramatic color change may need fewer coats. Cashmere and Ultra are mid-tier, and Premium Plus is the value tier. Coverage for most Behr interior paints lands near 350 to 400 square feet per gallon on smooth, primed walls.

One-coat claims

Behr markets Marquee and Dynasty as one-coat hide in many colors. In practice, keep the calculator at two coats for light-over-dark or for high-traffic rooms; set coats to 1 only for a close color match on a primed surface.

How to plan a Behr project

Start with room dimensions for a bedroom, living room, or office. Switch to total square feet if you already measured wall area from a floor plan. Include the ceiling only when you are painting it too, and add primer when bare drywall, stain blocking, or a big color shift is involved.

DIY vs professional

For DIY, set labor rate to 0 and budget Behr paint, primer, tape, rollers, trays, and drop cloths. For a pro quote, enter a local labor rate per square foot and a minimum charge.

Behr paint calculator FAQ

How much does a gallon of Behr paint cover?

Most Behr interior paints cover about 250 to 400 square feet per gallon. Premium lines like Marquee and Dynasty are formulated to cover in fewer coats, while lower-sheen everyday paints may cover closer to 350 to 400 square feet per gallon on smooth surfaces.

How many coats of Behr paint do I need?

Two coats is the standard for a durable finish and even color. Behr Marquee and Dynasty are marketed as one-coat hide in many colors, but a second coat is still recommended for dramatic color changes or high-traffic areas.

Does the calculator include Behr primer?

Only when you check "Include primer coat." Priming bare drywall or making a big color change usually needs a separate primer gallon, which the estimate adds at the primer price you enter.
