How Much Paint Is Needed to Paint Your Room?
To estimate how much paint you need for any interior paint job, you need to know the square footage of your wall and the number of square feet per gallon of the paint you are planning to use. The label on the gallon of paint will specify how many square feet each gallon will cover. Walls and ceilings are determine by the area, multiply length by width. To calculate the square footage of walls, measure the perimeter of the room and multiply this figure by its height. The result is the square footage of the wall space to be covered. Remember you might need more then one coat. When painting a deeply saturated color, you may even need a third coat of paint. Take the square footage and muliple by the number of coats, the result will determine your coverage per gallon.
