PAINT CALCULATOR

Door paint calculator

A typical interior door is 21 sq ft per face, 42 sq ft both sides, and panel doors run ~30% higher because of the panel reveal. One quart usually covers four interior doors. Use semi-gloss for cleanability and durability. The calculator returns the amount you need plus a real per-gallon price for any of 15 brands, so you see the paint cost before you shop.

HOW IT WORKS

How much paint per door

A standard 30-by-80-inch door is about 21 square feet per face. The calculator starts from a per-face area for your door type, doubles it if you paint both sides, adds about 25 percent for the jamb if you include it, then multiplies by coats and divides by your paint's coverage. These are the per-face areas it uses:

  • Flush slab interior: about 21 sq ft per face. One quart paints roughly six doors at two coats.
  • Six-panel or shaker: about 28 sq ft per face since panel reveals add area, roughly four doors per quart.
  • Exterior front door: about 25 sq ft per face, and often only the outside needs paint.
  • French door: about 18 sq ft per face because the glass lights subtract area, but expect more brushwork.
  • Garage, barn, or utility: about 21 sq ft per face, usually painted both sides.

Why semi-gloss for doors

Doors are touch points. They get fingerprints, scuffs, kicks, and pet scratches. Semi-gloss wipes clean and resists wear, while flat or eggshell on a door looks tired in two years. The one common exception is a barn-style sliding door painted as a feature wall, which can match the wall finish in satin or eggshell. On steel and fiberglass exterior doors, prime with a bonding primer first or the topcoat will scratch off the factory finish within a season.

Pull the door, lay it flat

Painting a hung door invites drips and visible brush marks on the panel reveals. Pull the door off its hinges, lay it flat across two sawhorses, and roll-and-tip with a foam roller or spray it. On a panel door, paint the recessed panels first, then the rails and stiles, so you can catch any runs before they set. You can usually rehang the door the same day.

Paint cost by brand

Door and trim enamels go on a little thicker than wall paint, so coverage is a touch lower — plan for about 350 to 425 sq ft per gallon. A door job is small, though: a single quart covers four to six interior doors, so the per-gallon price below matters less than buying the right size. These are current per-gallon prices for the door enamels the calculator can price:

Pick a brand and line in the result panel for an exact paint cost; most door jobs only need a quart or two, so buying the right size matters more than the per-gallon price.

What it costs to paint a door

Doing it yourself is cheap. A single door costs about $15 to $40 in paint and supplies, and because one quart covers four to six interior doors, a whole-house door refresh is often just $40 to $100 in materials plus a foam roller and a quart or two of enamel.

Hiring a pro is mostly labor — usually 50 to 70 percent of the bill. Expect about $75 to $150 per interior door and frame, and up to $200 to $300 for a detailed or exterior door that needs bonding primer and extra prep. A steel or fiberglass exterior door costs more because the factory finish has to be sanded and primed first. For a full labor-plus-paint estimate, use thepaint cost calculator.

Frequently asked questions

How much does it cost to paint a door?+
DIY, a single door costs about $15 to $40 in paint and supplies, and one quart covers four to six interior doors. Hiring a pro is mostly labor, roughly $75 to $150 per door and frame, or up to $300 for a detailed exterior door. Pick your brand in the result panel above for an exact paint cost.
Does this work for Sherwin-Williams, Behr, or Benjamin Moore enamel?+
Yes. The result panel prices all 15 brands we track, including their door and trim enamels — Sherwin-Williams ProClassic, Behr Marquee, and Benjamin Moore ADVANCE. Door enamel coverage is a touch lower than wall paint, about 350 to 425 square feet per gallon, and the panel uses each line's real number.
How much paint do I need for one door?+
A standard interior door is about 20 to 21 square feet per face, so roughly 42 square feet for both sides. Two coats use under a quart, and one quart of semi-gloss covers four to six interior doors.
How many doors will a gallon of paint cover?+
At about 400 square feet per gallon, one gallon covers roughly 18 to 20 door faces at a single coat, or about nine to ten doors painted both sides with two coats.
Does a panel door need more paint than a flush door?+
Yes. The raised panels and reveals add surface area, so a six-panel or shaker door runs about 28 square feet per face versus 21 for a smooth flush door, roughly 30 percent more paint.
Can I paint a steel or fiberglass exterior door?+
Yes, but use a bonding primer first. Topcoat applied straight over the bare factory finish will scratch off within a season.
What sheen is best for doors?+
Semi-gloss. Doors are touch points that collect fingerprints, scuffs, and kicks, and semi-gloss wipes clean and resists wear. Flat or eggshell on a door looks tired within a couple of years.
Should I take the door off to paint it?+
For the best finish, yes. Pull the door off its hinges, lay it flat across two sawhorses, and roll-and-tip or spray it. Painting a hung door invites drips and brush marks in the panel reveals.
