Surface Area Calculator

Our surface area calculator will help you determine the overall surface area of your pond, a very important calculation for determining the number of aquatic plants to use.

This figure is also important for determining fish load and algae control.

The calculator will determine the surface area on either a square pond or irregularly shaped pond. 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 numbers requested when using this calculator will be length times width. In figuring a round pond, these two numbers will be exactly the same, therefore use the corresponding calculator.
