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.
To calculate the size follow these simple guidelines: 1  Measure the length of the pond at the longest point. 2  Measure the width of the pond at the widest point. 3  Measure the depth of the pond at its deepest point.  Take twice the maximum depth and add it to the length at the longest point to get the overall length.
