PVC pond liners are the least expensive choice when it comes to water containment. The size of a pond liner required is determined by measuring the width, length and depth of your pond. This calculation is also used to determine the volume of water to fill said pond size.

Garden space is usually what determines the dimensions of a pond build, which ideally needs to be in proportion to the other elements that make-up the space in its entirety. When planning your pond, it is important to remember to maximise the space available because larger ponds are easier to maintain. The greater the volume the longer it takes to warm-up in the summer months, whereas a small, shallow pond warms up quickly in sunny weather which then provides the perfect conditions for algae and bacterial growth. Ponds need to be at least 2 feet deep (0.6m) to avoid these issues. In Northern Hemisphere cold winter climates, ponds should also be more than 3 feet (0.91m) deep to avoid freezing over.

To calculate pond volume use the following formula: Length x Width x Depth x 7.4

How to order your PVC pond liner

Use our pond liner calculator to work out what size pond liner and protective underlay liner you need for your pond. Enter pond length, width and depth plus a recommended overlay of 30cm or 12 inches. The calculator will then determine how much pond liner you need.

Once you have calculated the pond liner size, visit PVC pond liner page to input your order requirements and then do the same to order your Geotextile protective underlay liner.

Please note: Orders for a PVC liner must be between 2 and 10 meters in width. The width must be rounded up to the nearest whole number and length to the nearest half.
