How Big should a liner be... ?

Remember when calculating the size of the liner you need, that it is not only the overall length of the pond, but also the width and depth. For example you are building a pond 12ft x 10ft x 4ft deep and allowing for an adequate overlap around the pond - you will need a liner *24ft long x 22 ft wide.

*To order a custom liner please remember all sizes are in five-foot increments, so for the above example you will need to round up and order a liner that is 25 x 25 ft. in size.
