Measure the width of each wall and then add them all together.
This is how you find the perimeter of the room, e.g. 20’+20’+12’+12’ = 64’
Then multiply the perimeter, by the height of the walls.
This is how many square feet you have to cover, e.g. 64’x 8’ = 512 sq/ft
One gallon of Sissons paint covers approximately 400-450 square feet.
Therefore this room would require about 1.5 gallons of paint to cover.
Be sure to purchase enough paint to completely cover the desired area.
