How to calculate the square foot surface area of your pond

• Tape measure
• Calculator
• A place to make note of your measurements

1. Measure your ponds length (L); note size
2. Measure your ponds width (W); note size
3.  Multiply them together L X W= sq ft; note size.

A 10 x 8 pond would have a square foot surface area around 80 sq ft.

Circle ponds and irregular shaped ponds are a bit more challenging to calculate. The below steps assume your pond is a perfect circle. If it is not you may need to estimate.

1. Measure the widest distance across the pond this to get the diameter; note size
2. Divide the diameter in half to get the radius; note size
3. Multiply the radius by the radius
4. Multiply the product in 3 by Pi (3.14), note size.

If your pond has a diameter of 10 ft it has a radius of 5 ft it would roughly have a square foot surface area of 78.5 sq ft.  (5x5=25x3.14=78.50)
