How to Calculate Pond Liner
What is Pond Liner?
A pond liner calculator estimates the size of liner needed for a garden pond, including the overlap required to secure the liner over the edges. The standard formula: liner length = pond length + (2× max depth) + 0.6m overlap; similarly for width.
Step-by-Step Guide
- 1Liner length = Pool length + (2 × maximum depth) + 0.6m
- 2Liner width = Pool width + (2 × maximum depth) + 0.6m
- 3For irregular shapes, calculate based on maximum dimensions
Worked Examples
Input
Pond 2m × 1.5m · depth 0.7m
Result
Liner: 4m × 3.5m
2+(2×0.7)+0.6=4.0m; 1.5+(2×0.7)+0.6=3.5m
