How Many Gallons of Paint Do You Need for an Exterior House?

Painting your exterior house isn’t just about aesthetics—it’s a key step in protecting your home from the elements. But knowing exactly how many gallons to buy ensures you neither underspend nor overstock, saving both money and hassle.

Determining the right number of gallons depends on wall area, paint coverage, and surface condition. Most exterior paints cover between 400 to 500 square feet per gallon. For a typical 2,000 sq ft house, plan for roughly 5 to 6 gallons. Always add 10-15% extra to account for uneven surfaces, cuts, and touch-ups. Use the formula: (total sq ft ÷ coverage rate) plus 10-15% to estimate accurately.

Several variables influence your paint needs: wall texture (smooth vs. stucco affects absorption), number of coats (two coats typically double the gallons), and paint type (matte finishes may require more coverage than glossy). Inspect your home’s exterior closely before calculating—cracks, weather damage, and previous paint layers can increase consumption.

Start by measuring interior wall heights and total square footage. Divide by average coverage (usually 400-500 sq ft/gal). Then, apply a 10-15% buffer for mistakes and uneven application. Use online paint calculators or consult your paint store for precision. This ensures you buy just enough without waste—ideal for budget control and timely project completion.
