Tips on Measuring for Paint
Before you begin, take the room measurements in the list below - round to the nearest foot. If you have cathedral ceilings that create sloping walls, follow the special case instructions on how to derive this square footage.
To ensure you will have enough paint, do not worry about excluding areas not to be painted, such as windows and doors. Additionally, a 10 percent waste allowance is automatically added to the total.
Homeowner Tip - One gallon of paint covers approximately 400 square feet.
