The amount of paint needed to cover a two-car garage will vary based on several factors. The homeowner will need to calculate the square footage of the surface that will be painted and research the covering capacity of the paint being chosen. Because garages are usually four-sided rectangular structures, the process is not difficult.

## Calculating Paint Needs for a Garage

Calculate the surface area of the exterior walls of the garage. Start with walls without peaks. The surface area is the length of the wall times the height, measured in feet. A garage wall 24 feet long and seven feet high would have an area of 168 square feet. Subtract large openings, like the garage door, by using the same method to determine the area of the garage door. Small openings like windows and walk-in doors can be ignored when estimating the paint needs for the building.

Walls with a peak are a little more difficult. Start by measuring the width of the wall and the height of the point where the roof starts. Multiply these two numbers to determine the area of the lower part of the wall. Measure the width of the wall at the point where the roof starts and the height of the peak above an imaginary line running between the lower points of the roof on each side. Multiply these two numbers and divide by two.
