Paint for 1,500 sq ft
Covering 1,500 sq ft of wall with 2 coats means spreading paint over 3,000 sq ft in total. At standard paint's ~375 sq ft per gallon, that's about 8 gallons, roughly $240–$360 in paint.
One gallon covers ~350–400 sq ft depending on the grade and how thirsty the surface is. Bare drywall, deep or bright colors, and rough or textured walls all cut coverage, so buy about 10% extra for touch-ups and the inevitable second pass on tricky spots.
What changes how much you need
| Factor | Effect on paint needed |
|---|---|
| Number of coats | Two coats is standard — it doubles the coverage area vs a single coat |
| Paintable area | ~1,500 sq ft here after subtracting doors and windows |
| Paint grade | Economy covers ~350 sq ft/gal, premium ~400 — better paint also hides in fewer coats |
| Surface & color | Bare drywall or a big color change needs primer or an extra coat |
| Openings | Each door (~21 sq ft) and window (~15 sq ft) is area you don't paint |
| Wall texture | Textured, rough, or porous walls drink noticeably more paint than smooth ones |

Painting tips
- Buy about 10% more than the estimate — you'll want it for a second coat on tricky spots and future touch-ups.
- Prime bare drywall, patches, and any drastic color change first; primer stops the topcoat from soaking in unevenly.
- Box your gallons — mix them together in one bucket — so the color stays consistent from the first wall to the last.
- A pricier paint that covers in one or two coats can beat a cheap one that needs three — compare cost per finished wall, not per gallon.
