As a general guideline, consider both dry and wet environments. A 12×12 room covers 144 square feet. For a 584 sq ft area, like a 12×12 space, you’ll need approximately 0.003 x 584 = 1.75 gallons of paint. So, for a fresh coat in a 12×12 room, plan on 1.75 gallons or 6.63 liters to cover ceilings, walls, and trim.
