Paint Calculator

Save money and avoid leftovers. Use this calculator to figure out the amout of paint needed for your next painting job.

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.
