Here is how to calculate exterior painting area:
Measure Every Wall: Begin by using a tape measure to find the width and height of every exterior wall. Measure in feet, okay?
Calculate Individual Wall Area: Now, you need to calculate the wall area of each wall. To do this, multiply the width by the height for every wall to get the square footage. Use this formula for every exterior wall.
Total Wall Area: After this, add up the square footage of all the walls to get the total wall area of the exterior surface.
Non-Paintable Area: Use the same method and measure the width and height of all the non-paintable regions, which include the doors, windows and other unpaintable surfaces.
Calculate each Area: Then calculate the individual areas by multiplying the width by the height. Add all these areas up and subtract them from the total wall area from the 3rd step.
Measure Trim and Details: Measure linear feet of trims, railings, etc. Multiply by their average width to estimate these areas separately.
Calculate for Coats: Multiply the final net paintable square footage by the total number of coats you plan to apply, which is usually 2 to 3. This will give you the total area needed to be painted.
Add Wastage: You should add about 10 percent extra for spills, touch ups and waste.
This is all about the process to calculate the exterior paint area for a house. I hope you will find this useful.
