Choose the Right Pond Liner

What Size Liner Do I Need?

The formula for sizing a pond liner is simple.

Pond Length + (2 Times Depth) + 2' = Liner Length
Pond Width + (2 Times Depth) + 2' = Liner Width

So...if you want a finished pond 12' long and 7' wide and 3' deep then the liner size you need is:

12' + (2 x 3') + 2' Long
7' + (2 x 3') + 2' = 15' Wide

This basic formula will work for all pond shapes.

How Many Gallons is My Pond?

The formula for determining the number of gallons of water in a pond is also simple.

For Square and Rectangular Ponds
Length times Width times Depth times 7.5 = Gals

For Round Ponds:
Radius times Radius times 3.14 times 7.485 = Gals

The gallons in our sample pond (left) is:

112 x 7 x 2 x 7.485 = 1,260 Gals
