How do I choose the right size of pond liner for my pond?
Measure the maximum length, width, and depth of your intended pond shape. Then, allow extra overlap (typically 20–30 cm) on all sides to accommodate trenches, edging, and anchoring.
For example, a 2 m × 1.5 m rectangular pond that's 0.6 m deep would need a liner roughly 2.6 m × 2.1 m.
