Use the following formula to estimate the amount of wall paint you need. Double the result if the walls require two coats.
1. Add together the length of each wall.
14 + 20 + 14 + 20 = 68 feet

2. Multiply the sum by the wall height, to find the total wall area.
68 × 8 = 544 square feet

3. Subtract 20 square feet for each door (20 × 2 = 40) and 15 square feet for each window (15 × 2 = 30) to find the actual amount of wall area you're painting.
544 – 70 = 474 square feet

4. Divide this figure by the paint coverage (350 square feet per gallon), and the result is the number of gallons to purchase.
474 ÷ 350 = 1.4

For this example, you want to buy 1 gallon and 2 quarts of paint for a single coat.
