**1. Multiply the length of the door by the width of the door to calculate the square footage of one side of the door**

**Door Length X Door Width = Square Footage of One Side of Door**

**2. Multiply the square footage of one side of the door by 2 to determine the square footage of both sides of the door**

**Square Footage of One Side of Door X 2 = Square Footage of Both Sides of Door**

**3. Multiply the square footage of both sides of the door by 2 to determine the square footage for 2 coats of paint (2 coats is always recommended)**

**Square Footage of Both Sides of Door X 2 = Square Footage for 2 Coats of Paint**

**(IF THE DOOR HAS WINDOWS THEN CONTINUE TO STEP 4)**

**4. If the door has a window, multiply the length of the window by the width of the window to calculate the square footage of one side of the window**

**Length of Window X Width of Window = Square Footage of One Side of Window**

**5. Multiply the square footage of one side of the window by 2 to calculate the square footage of both sides of the window**

**Square Footage of One Side of Window X 2 = Square Footage of Both Sides of Window**

**6. Subtract the square footage of both sides of the window from the square footage for 2 coats of paint to calculate square footage for 2 coats of paint of door with window**

**Square Footage for 2 coats of paint - Square Footage of Both Sides of window = Square Footage of 2 Coats of Paint for Door With Window**

**(IF A DOOR HAS MUTLIPLE WINDOWS THEN COMPLETE STEPS 4-6 FOR EACH WINDOW)**
