Color is always the first consideration when painting a home. Most paint manufacturers offer samples to try that can allow you to make a more informed decision. Because light within a room may vary from wall to wall as well as from day to night, try painting a large piece of poster board in the color or colors you are considering. Move the board from wall to wall and look at it for a minimum of 24 hours at a time in each space to make sure you like the color before committing.
Generally speaking, a gallon of paint will cover about 350 square feet. If this is the first time drywall is painted, it will soak up more paint. And remember to factor in whether your job will require one or two coats of paint. Dark and bright colors will require more coats of paint, as will painting a lighter color over an existing darker color. Divide the paintable wall surface by 350 to determine how many gallons of paint you will need to buy. If there’s an odd number with less than .5 leftover, round down, if it’s over .5 round up.
