One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom.
Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room. This is the most common amount needed especially when considering second coat coverage.
Three gallon cans of paint cover up to 1200 square feet. This is enough to cover a large room or a couple average sized rooms adjoining each other. You may want to consider this extra can if you are doing a room with vaulted ceilings.
Four gallon cans of paint cover up to 1600 square feet, which is enough to cover several average rooms. You might consider this amount if you have a great room or some other very large room(s).
