How do you calculate the amount of paint needed for a job?

The correct approach to calculating the amount of paint needed for a job involves measuring the wall area, subtracting the area taken up by windows and doors, and then dividing by the coverage provided by a gallon of paint. This method ensures that you take into account the actual surface area that will be painted, leading to a more accurate estimate of the paint required.

Measuring the wall area provides a clear understanding of how much vertical space needs coverage. It’s important to subtract the areas of windows and doors because these surfaces do not require painting, and failing to do so might result in purchasing excess paint. Each gallon of paint typically covers a specific square footage, which is crucial for determining how many gallons to buy based on the effective wall area.

This logical step reduces waste and ensures the job is completed efficiently without multiple trips to the store for additional supplies.
