What is The Average Pond Size?

Not to sound too complicated, but before we dive into answering “What is an average pond size?” we’d like you to first decide whether you believe in anything average in life. We understand the importance of a perfect sized pond to complement its surrounding, however we also know that each pond is individually designed taking into account the preferences of homeowners.

This is why giving an average of a pond size is not as simple as it may sound.

Every homeowner has his/her own preferences when it comes to decorating the exterior of their residence. More importantly each home has a different space available for installing the pond. Therefore, the very first step in determining the right size of pond for your home would be to see how much space you have for this feature.


Some people may have an entire acre of land for installing the pond, while others may just have a small side to their home. In both scenarios, with a little measurement and hard work you can have a perfect sized pond for your home.

If you are looking to find out the average size of a pond in statistics then the most common size of a pond with a waterfall feature is about 10’ x 15’. However, we would like you to give attention to the surface area of the pond.

As you decide to add a waterfall, the overall surface area of the pond will be increased. Given this situation, the statistics we just provided you will be skewed. This is exactly why keeping the water stream into consideration is highly important while deciding the size of your pond.

The depth of an average pond, however, is about 24 inches at the deepest points.


While the size of the land where you are planning to install the pond matters a lot, there is a certain way you can find the right size of the pond for your garden or backyard.

First, we recommend that you take several measurements to determine the average width and length. Don’t forget to get both the shortest as well as longest distances while you are calculating the average length. Same goes for calculating the width, measuring the narrowest as well as widest distances.

The more measurements you take, the more accurate will be the result.

When you are looking to convert the square feet, divide your calculated measurements by 43,560 ft2 per acre. The final results will be dependent on the length and width and the actual pond surface area will be about ±20 percent.


First thing’s first, the volume of water in the pond is measured in acre feet. So one acre foot represents a single acre of surface which is roughly one foot deep.

The key point here is that the acre feet of every pond is different according to its shape. This is why for a typical bowl shaped pond, the average depth will be calculated at 0.4 times the depth of the pond.

Given these stats, a 12 feet pond will have an average depth of 4.8 feet approximately.


If you are aware of ponds, you must know that almost every pond has shelves placed inside to support the plants.

So to determine the placement of shelves in an average pond, let’s do a quick maths. The bottom of an average sized pond is 24 inches deep. Given this measurement, the shelves will be placed at 12 inches with an approximate width of 24 inches.

This way your plants will be sat in an upward position in the pond.


The shape of the pond is another important factor you need to consider before installing it. While you can be as imaginative with the shape as possible, it will play a significant role in the structuring and placement of the pond. We have jotted down some of the most common yet famous shapes of pond for you.


A round shaped pond is the most common one, it is also easy to decorate. Also a circular shaped pond is likely to complement small spaces giving them a fuller yet elegant look. It will prevent the small space from looking over stuffed.


The simpler, the better. This notion cannot be truer. A rectangular shaped pond is not only easy to manage but it also goes easy on your budget. The simpler shape you choose, the easier it will be for you to manage. A plus point is, with a rectangular pond, you can add different decorative pieces to all four sides.
