Pond Size And Depth. by Tom Burton. Once the where is decided, we need to determine size and depth. An ideal pond for the average hobbyist is between 23 and 25 feet long by 12 to 13 feet wide and 3 to 4 feet deep.
2. Multiply the length radius by the width radius by 3.14 by the depth in feet. This will give you the volume in cubic feet. An oval pond thatâs 4 feet deep, 20 feet long and 10 feet wide has a length radius of 10 feet and a width radius of 5 feet.You multiply 10 feet by 5 feet by 3.14 by 4 to get 628 cubic feet.ultiply the radius of the pond by itself and then by 3.14. Multiply this product by the depth in feet to find the cubic feet of water. A circular pond 4 feet deep and 20 feet in diameter has a radius of 10 feet.
