If you’re painting your home, garage, or office, you may be wondering: how many square feet will 5 gallons of paint cover?

The answer depends on the type of paint and the surface being painted, but in most cases:

Five gallons of paint will cover approximately 1,750 to 2,000 square feet with one coat.

Most standard interior and exterior paints cover:

350–400 square feet per gallon

In this guide, you’ll learn how to estimate paint coverage and calculate how much paint you need.

Quick Answer: Paint Coverage for 5 Gallons

The average paint coverage is:

1 gallon = 350–400 square feet

For 5 gallons:

5 × 350 = 1,750 square feet
5 × 400 = 2,000 square feet

Therefore:

Five gallons of paint typically covers between 1,750 and 2,000 square feet.

Paint Coverage Formula

To estimate coverage, use this formula:

Square Feet Covered = Number of Gallons × Coverage per Gallon

For example:

5 gallons × 400 square feet

Calculation:

5 × 400 = 2,000 square feet

Paint Coverage Chart

Paint Amount	Approximate Coverage
1 gallon	350–400 sq ft
2 gallons	700–800 sq ft
3 gallons	1,050–1,200 sq ft
5 gallons	1,750–2,000 sq ft
10 gallons	3,500–4,000 sq ft

How Many Rooms Can 5 Gallons Paint?

Five gallons of paint can usually cover:

4–6 average bedrooms.
A large living room and hallway.
The interior walls of a small apartment.
A garage or basement.

The number of rooms depends on ceiling height and wall size.

One Coat vs. Two Coats

Keep in mind that most painting projects require two coats.

One Coat

Covers 1,750–2,000 square feet.

Two Coats

Covers 875–1,000 square feet.

If you’re painting over a dark color, you may need additional paint.

Factors That Affect Paint Coverage

Several factors can change how much area 5 gallons will cover:

Wall texture.
Paint quality.
Number of coats.
Surface condition.
Primer usage.
Roller type.

Rough surfaces absorb more paint than smooth walls.

Interior vs. Exterior Paint Coverage

Paint Type	Coverage per Gallon
Interior paint	350–400 sq ft
Exterior paint	250–400 sq ft

Exterior surfaces often require more paint because they are rougher.

Example Paint Project

Suppose you are painting a room with:

Four walls.
Total wall area: 1,800 square feet.

Five gallons of paint would be enough for:

One full coat.

For two coats, you would likely need additional paint.

How to Calculate Your Wall Area

Measure:

Length of each wall.
Height of the walls.

Then multiply:

For example:

Wall length: 20 feet.
Wall height: 8 feet.

Calculation:

20 × 8 = 160 square feet

Add all wall areas together to estimate your paint needs.
