To calculate the correct dimensions for your pond liner you need to account for the depth of your pond, as well as its width and length. To save you from the headache of calculating this yourself we’ve created the Pond Liner Calculator.

Simply use the sliders on the calculator below then select the amount of overlap you need based on the size of your pond.

Now you know the size of liner you will need, simple select the type of liner you require: FIRESTONE PONDGARD™, SEALECO EPDM 0.75MM POND LINER, SEALECO EPDM 1MM POND LINER
