Pond Volume Calculator

Our pond volume calculator will determine how much water your pond, regardless of shape, will hold.

If you have a kidney shaped pond, or any other unusual shape, visualize the shape as an oval, and then enter the figures into our calculator.

The objective is to determine an estimated total width and length of your unusually shaped pond.

For a round pond, the length and width will be the same.

Figuring the volume of your pond impacts all aspects of pond keeping.
