POND LINER PROJECT PLANNER
From pond dimensions to a one-piece liner order.
Calculate the required liner rectangle from maximum pond dimensions, depth and overlap; rotate it against stock roll widths, add underlay, check an existing liner, compare the exact project with a budget, or compare suppliers with different roll widths.

WHY THIS PLANNER IS DIFFERENT
Size the liner, then size the roll purchase.
The basic liner formula only gives a rectangle. The buying decision depends on whether that rectangle fits the supplier's stock roll in one piece, whether rotating it reduces linear footage, and whether underlay and delivery change the better quote.
Plan the orderCalculate liner dimensions, roll footage, underlay, pond perimeter and an optional water-volume reference.
Check an existing linerTest the piece in both orientations and see whether it covers the required one-piece rectangle.
Check the budgetCompare the exact liner-and-underlay system with the amount you plan to spend.
Compare suppliersAccount for different roll widths, linear-foot prices, underlay, tax and delivery.
