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

  1. 1Liner length = Pool length + (2 × maximum depth) + 0.6m
  2. 2Liner width = Pool width + (2 × maximum depth) + 0.6m
  3. 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
