How Big A Paint Job Do I Need Inside Williams, Sherwin?

The average size of a 2,000-square-foot house requires about 5 gallons of paint to cover it, which can be calculated using Sherwin-Williams’ Paint Calculator. This tool is easy to use and takes the guesswork out of determining the amount of paint needed for a painting project. To calculate the paint needed, input the measurements of the surface to be painted, such as length, width, and height. The calculator will then calculate the number of square feet and find the paint needed per gallon for your interior room, ceiling, or exterior siding.

The type of paint used depends on the room to be painted and the desired finish. Interior paint is specifically designed for this purpose. The Paint Calculator supports doors and windows, number of coats, and custom paint coverage. It estimates the amount of paint, primer, and ceiling paint needed for any project by calculating the square footage of the walls and estimating the paint and primer needed.

To determine the amount of paint needed, multiply the height by the width of each wall you plan to paint. For example, if your average bedroom is about 360 sq ft, one gallon would likely work (depending on color). If not, two with about a half gallon left is recommended. The general rule of thumb is one gallon per 400 square feet, but for professional interior painting, the cost per square foot typically falls between $9.50 and $20.

To calculate the paint needed for a given surface, first calculate the square feet of space that will be coated. Then, input the dimensions of the room to be painted and click the button to calculate the amount of paint and man-hours needed for the job.
