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
