Use the result as a planning estimate and verify project-specific measurements, product information and site conditions where relevant.
How it works
Twice the maximum depth and twice the edge overlap are added to both the pond length and width.
liner length = pond length + 2 × depth + 2 × overlapWorked example
For a 10 ft × 8 ft pond, 2 ft deep with 1 ft edge overlap, the minimum liner rectangle is 16 ft × 14 ft.
Assumptions
- The formula assumes the maximum depth is applied conservatively to both dimensions.
Limitations
- Complex shelves, vertical walls and irregular profiles may require extra liner; confirm final dimensions before ordering.
