How Many Square Feet Does 5 Gallons of Paint Cover?

If you are planning a home renovation or painting project, one of the most common questions is: how many square feet does 5 gallons of paint cover?

Paint coverage depends on surface type, paint quality, and how it is applied. However, there is a standard industry estimate that helps with planning.

Five gallons of paint typically covers about 1,600 to 2,000 square feet per coat.

This makes a 5-gallon bucket ideal for painting large rooms, multiple rooms, or even small homes.

Quick Answer

Standard paint coverage rate:

$1 \text{ gallon} \approx 350 \text{ to } 400 \text{ square feet per coat}$ 1 gallon≈350 to 400 square feet per coat

Now multiply:

$5 \times (350 \text{ to } 400) = 1750 \text{ to } 2000 \text{ square feet}$ 5×(350 to 400)=1750 to 2000 square feet

Final Answer:

5 gallons of paint covers approximately 1,750 to 2,000 square feet per coat.

Standard Paint Coverage Rate

Most interior latex paints cover:

$1 \text{ gallon} \approx 350 \text{ to } 400 \text{ sq ft}$ 1 gallon≈350 to 400 sq ft

This is for:

Smooth drywall
Properly primed surfaces
One coat of paint

5-Gallon Paint Coverage Calculation

Using the standard range:

Low estimate:

$5 \times 350 = 1750 \text{ sq ft}$ 5×350=1750 sq ft

High estimate:

$5 \times 400 = 2000 \text{ sq ft}$ 5×400=2000 sq ft

Final range:

1,750 to 2,000 square feet

Interior vs Exterior Coverage Differences

Interior painting:

Smooth surfaces
Better coverage
Less paint absorbed

Exterior painting:

Rough surfaces (brick, stucco, wood)
More absorption
Lower coverage per gallon

So exterior coverage may drop closer to:

1,500–1,800 sq ft per 5 gallons

Factors That Affect Paint Coverage

1. Surface texture

Rough walls absorb more paint.

2. Primer usage

Primed walls require less paint.

3. Paint quality

Higher-quality paint spreads further.

4. Application method

Roller = standard coverage
Spray = may vary
Brush = less efficient

How Many Coats You Need

Most projects require:

1 coat primer
1–2 coats paint

So actual coverage needed is doubled:

$1750 \div 2 = 875 \text{ sq ft effective per coat system}$ 1750÷2=875 sq ft effective per coat system

Real-World Painting Examples

Small home interior

1,200–1,800 sq ft walls
5 gallons usually enough for one coat

Large room repaint

300–600 sq ft per room
Multiple rooms per 5-gallon bucket

Exterior siding

Depends heavily on material texture

Common Mistakes When Estimating Paint

Ignoring surface texture

Stucco uses more paint than drywall.

Not accounting for multiple coats

Most projects need at least two coats.

Forgetting trim and ceilings

These add extra square footage.

Expert Tips for Accurate Painting

Always measure wall area

Height × width per wall.

Buy extra paint

Plan for 10–15% waste.

Use primer when needed

Improves coverage efficiency.
