Make sure you have the right size pond liner for your pond. Pond liners are never a perfect fit for your hole, so some excess will always need trimming. Our pond liner calculator helps you find the closest match.

Simply provide your pond’s maximum length, width, and depth. The calculator includes a 12” (30 cm) overlap around the edges, so you can secure the liner in place. Enter your measurements in the top three boxes, and your pond calculations will appear below.

If you provide your email address, we’ll also send the results to you for future reference. Then, visit our Pond Liners page to select your liner and underlay. (This link opens in a new tab so you can refer back here.)

Need to convert meters to feet? Multiply your measurements by 3.28. For example, 3 m × 3.28 = 9.84 ft.
