Interior Painting Projects

These paint calculators were designed to help you figure out approximately how much paint you will need to purchase for your next home improvement project. Follow these simple steps to use the paint calculator:

For Interior Painting Projects:

1. Measure the distance from floor to ceiling.

2. Measure the length of each interior wall you plan to paint.

3. If you plan to paint the ceiling, measure the length and width of the ceiling. For irregularly shaped rooms, you may need to break the room into sections and measure each section.

4. Measure the length and width of any areas that will not be painted, such as windows, fireplaces, door openings, etc. Note that our paint calculator uses certain default values for size of windows and doors (Single doors - 20 ft2, Double doors . 40 ft2, Small windows - 10 ft2, and Large windows - 25 ft2). If your doors and windows are similar in size, use the default values. Otherwise, measure your doors and windows, and enter the measurements in the "other unpainted area" fields.

5. Decide how many coats of paint you plan to apply.

6. Check with your paint dealer of the paint manufacturer to determine the coverage rate (the number of square feet covered by one gallon of paint) for the paint you plan to use. Keep in mind that the coverage rate may vary depending on the method of application, the condition of the surface being painted, etc. Your paint dealer should be able to help you figure out an approximate coverage rate for your project.

7. Enter the information above into the paint calculator, and press the "calculate" button to figure out how much paint you need to buy!

Note: If the paint calculator does not have enough fields for you to enter the measurements of all of your walls, ceilings, or unpainted areas, divide the room into sections and calculate the amount of paint you need for each section.

Exterior Painting Projects

1. Measure the length and height of each exterior wall you plan to paint. Measure only surfaces you plan to paint (for example, don. t measure brick or stone covered surfaces). For walls with gables, measure the height to the base of the gable.

2. If you plan to paint any gables, measure the base, and the distance from the base to the peak of each gable.

3. Measure the length and width of any areas that will not be painted, such as windows, door openings, garage doors, exterior chimneys, etc. Note that our paint calculator uses certain default values for size of windows and doors (Single doors - 20 ft2, Double doors . 40 ft2, Small windows - 10 ft2, and Large windows - 25 ft2). If your doors and windows are similar in size, use the default values. Otherwise, measure your doors and windows and enter the measurements in the "other unpainted areas" fields of the paint calculator.
