Pond Liner Measuring Tips
These pond liners are flat sheets meaning that the entire girth of the pond cavity needs to be included in the sheet measurements to ensure that your sheet is large enough.
Using a flexible tape measure (or rolling measure), measure across the pond at its widest point whilst following the contour of the bottom of the pond - be sure to include:
(overlap area + slope/wall + across bottom + slope/wall + overlap area)
** This is the minimum total sheet width that you require **
Repeat above for the length
