How Much Behr Paint Do I Need?
A gallon of Behr paint covers 250 to 400 square feet in one coat. Most interior repaints land near 350. Deep colors, bare drywall, and texture push you toward the low end, which is why a 12x12 room in two coats usually takes two gallons rather than one. Enter your room below to get a number based on your actual walls instead of the label estimate.

Behr coverage by product line
Behr publishes the same 250 to 400 sq ft per gallon range across its interior lines. The lines differ in how well they hide the old color and how much scrubbing they take, not in how far a gallon goes. Pick the line for durability and one-coat hide, then use the calculator for quantity.
| Behr line | Coverage per gallon | What it is for |
|---|---|---|
| MARQUEE Interior | 250-400 sq ft | One-coat hide on a strong color change |
| Dynasty Interior | 250-400 sq ft | Highest stain and scuff resistance |
| Ultra (Premium Plus Ultra) | 250-400 sq ft | Paint and primer in one on sound walls |
| Premium Plus Interior | 250-400 sq ft | Budget repaints where the color barely changes |
| MARQUEE Exterior | 250-400 sq ft | Siding, trim, and doors |
Ranges are Behr published figures. Deep and saturated colors sit at the bottom of the range, and unprimed or textured surfaces cut coverage by roughly 15 to 35 percent. Always check the label on the can you buy.

Frequently Asked Questions
How many square feet does a gallon of Behr paint cover?
Behr publishes 250 to 400 square feet per gallon for one coat. Plan on about 350 for a smooth, previously painted wall in a similar color. Drop toward 250 for bare drywall, textured walls, or a deep color over a light one.
Does Behr Marquee cover more than Premium Plus?
Not in square feet. Both publish the same 250 to 400 range. Marquee is rated for one-coat hide on many colors, so it can cut the number of coats rather than the gallons per coat. If Marquee genuinely covers in one coat where Premium Plus needs two, you buy roughly half the paint.
How much Behr exterior paint do I need?
Behr exterior lines publish the same 250 to 400 sq ft per gallon. Exterior siding usually lands lower because the surface is rougher and more porous, so budget nearer 250 to 300 on wood, fiber cement, or stucco.
Is Behr a good paint brand?
Behr consistently ranks as a top consumer paint brand. Their Premium Plus and Marquee lines offer excellent coverage, durability, and color selection at a mid-range price point. Behr Marquee is their premium one-coat option.
Where can I buy Behr paint?
Behr paint is sold exclusively at The Home Depot, both in stores and online. They offer over 1,000 colors and custom color matching.
