How much paint do you need?

  1. Determine the total square feet of each area to be painted*:

    1. For each wall, multiply the height by the width:
      ft. x ft.= sq. ft.
    2. For each ceiling multiply the length by the width:
      ft. x ft. = sq. ft.

  2. Add up the total sq. ft. for all walls and ceiling to be painted:

    0 + 0 = 0 total sq. ft.

  3. Determine the number of gallons needed for one coat:

    Divide the total sq. ft. by 400:
    Total sq. ft./400 = 0 gallons of paint

0 gallons of paint per coat

*Keep in mind varying ceiling heights, window and door openings.
