Subtract 20 square feet for each door and 15 square feet for every window if you will be painting the trim around these areas with a different color. This gives you an estimate of the entire square foot area of the outside of the house. You must multiply this by two if you intend to apply two coats of paint to the exterior of the house.

Frequently Asked Questions
How do you figure square footage for painting?
To estimate the amount of paint you need in order to cover the walls of a room, add together the length of all the walls and then multiply the number by the height of the room, from floor to ceiling. The number you get is the room's square footage.
How do you calculate square footage for painting a house?
Add the individual sums together. Measure the height and width of each door and each window in a room to be painted. Multiply height by width to find the square footage of each door and window. Combine the totals for each door and window to calculate for house painting.
How to figure out how much paint to use on a door?
As a general estimate, you can subtract about 20 square feet per door and 15 square feet per window. Say a 700 square foot room has one door and two windows. You would subtract 20 for the door, and 30 for the window, resulting in a square footage of 650. Determine how much paint you need. A gallon of paint covers 250 square feet.
