These Are The Sizes For Koi Ponds That Will Help Your Koi Fish Live Happily And Healthily

Nobody wants to be put into a house that’s too small; it’s uncomfortable! Koi fish don’t either, which is why it’s important to have the right size pond for them.

In this post, you can find out the best backyard koi pond sizes and depths that a Kansas City, MI, koi pond builder uses. You can also find out what can change the average koi pond size.

What Are The Best Koi Pond Sizes?

Backyard koi pond sizes can range from 6 feet by 8 feet to 20 feet by 30 feet and larger. The size of the average pond can change from area to area but it’s usually about 150 square feet. Ponds smaller than 6 by 8 feet aren’t good homes for koi fish.

Smaller backyard koi ponds are at least 6 feet by 8 feet. This is usually a little over 1,000 gallons of water if the pond is 3 feet deep. Your pond can be smaller if you don’t want to put koi in it.

The average size backyard koi pond is about 10 feet by 15 feet. This is somewhere around 3,300 gallons if the pond is 3 feet deep.

Large backyard koi ponds are around 20 feet by 30 feet. This is about 13,500 gallons if the pond is 3 feet deep.

*These measurements are for rectangular ponds. Not all ponds come in nice, neat shapes like this. Many are irregularly shaped as it makes them look more natural and interesting.

What 3 Main Factors Can Change The Average Size Of A Backyard Koi Pond?

  1. Amount of available land per area. The average backyard pond size changes based on how much land is available in houses in an area. Some areas don’t have as much land available in homes. This decreases the average size of backyard ponds as they have to have smaller ones.
  2. Pond basin shape. Ponds can be circular, square, irregular, and other shapes. This can change what the average size can be in an area.
  3. Additions. Some pond contractors will count streams, wetland filters, and other additions as part of the pond. Others just count the actual pond basin. This can change the average size per area.

How Deep Should A Backyard Koi Pond Be?

Backyard koi ponds need to be at least 2 feet deep. This keeps the bottom part from freezing during the winter if you’re where winters get that cold. Some pond contractors recommend making backyard koi ponds 3 feet deep.
