To determine pond liner measurements use the following equation.

Length + (Depth x 2) + (Overlap x 2)
Width + (Depth x 2) + (Overlap x 2)

Example: Pond measures 12’ long x 17’ wide x 3’ deep.

12 + (3x2) + (1x2) = 20
17 + (3x2) + (1x2) = 25
Pond liner calculation equals a 20’x25’.

A 20’x25’ liner is recommended for this pond installation.
