The Benjamin Moore Paint Calculator is a valuable tool designed to simplify the process of estimating the amount of paint needed for a painting project. Whether you’re repainting a single room or tackling a larger renovation project, this calculator provides accurate estimates to help you plan your paint purchase effectively.
Formula of Benjamin Moore Paint Calculator
The formula used by the Benjamin Moore Paint Calculator is as follows:
Total Paint Needed (in gallons) = ((Total Surface Area – Total Area of Doors and Windows) / Coverage per Gallon) * Number of Coats
Where:
Total Surface Area: The combined surface area of all walls to be painted, calculated by adding the areas of each wall.
Total Area of Doors and Windows: The combined area of all doors and windows in the room.
Coverage per Gallon: The coverage provided by one gallon of paint, usually provided on the paint can label in square feet per gallon.
Number of Coats: The number of coats of paint desired for the project, typically 1 or 2 coats.
To calculate the total surface area, you can use the following formula:
Total Surface Area = 2 * (Length * Height) + 2 * (Width * Height)
Variables used:
- Length: The length of the room.
- Width: The width of the room.
- Height: The height of the room.
General Terms Table
| Paint Type | Coverage per Gallon (sq ft) |
|---|---|
| Flat/Matte Paint | 250-400 |
| Eggshell Paint | 200-300 |
| Satin Paint | 300-400 |
| Semi-Gloss Paint | 350-500 |
| Gloss Paint | 400-600 |
| Primer | 300-400 |
Please note that these coverage estimates are approximate and may vary depending on factors such as surface texture, application method, and paint quality. Always refer to the manufacturer’s specifications for the most accurate coverage information for a specific paint product.
Example of Benjamin Moore Paint Calculator
Let’s consider an example to illustrate how the Benjamin Moore Paint Calculator works:
Suppose you’re painting a room with the following dimensions:
- Length: 12 feet
- Width: 10 feet
- Height: 8 feet
You estimate that the total area of doors and windows is 50 square feet. The coverage provided by one gallon of paint is 350 square feet, and you plan to apply 2 coats of paint.
Using the formula mentioned above, you can calculate the total paint needed:
Total Surface Area = 2 * (12 * 8) + 2 * (10 * 8) = 384 square feet
Total Paint Needed = ((384 – 50) / 350) * 2 = 2.17 gallons
So, you would need approximately 2.17 gallons of paint for this project.
