SIZE

The decision for the size and shape of the pond should be determined by your own preference, and the size of the garden and the intended location.

In any case, the size of the pond plays an important part for the biological balance of the pond: the larger the pond is, the more natural the visual effect, and the better the conditions for plants and animals. If you intend to keep fish, your pond will need a minimum depth of 3 ft. to provide an ideal living environment especially in the winter. The table is designed to give you some rough guidelines for the calculation of the pond size and water volume.

Guidelines for pond sizes
Surface area	Depth
32 - 53 sq. ft.	23 - 31 inches
53 - 160 sq. ft.	31 - 39 inches
above 160 sq. ft.	more than 39 inches

A further consideration should be whether you intend to construct your pond with the help of flexible pond liner or a preformed pond. Preformed ponds have the advantage of a quicker and simpler installation.

As a rule, for ponds with less than 36 square feet you would choose a preformed pond with a minimum depth of 3 ft. Pond liner, however, has the advantage of infinite design possibilities.
