Liner Size Calculator

Our liner size calculator requires just 4 measurements.

Example of the measurements that you will have to have on hand are the length, width, depth and the amount of overlay you may need.

The overlay is the amount of liner material needed beyond the edge of the pond. If you want 2 feet, for rock and plant placement around the edge of your pond, enter 2 in the overlay box below.

You will need an underlayment, under your liner, the square footage figure will help you to determine the size of underlayment required.

Example:

EPDM pond liners are available in widths of 5 foot increments up to 30 foot in width. The length will be cut according to your requirements.
