Pond Liner Estimator

To estimate the amount of material needed:

  • Measure the length and width of the pond.
  • Measure the depth of the pond and double it. Add this number to both the length and width measurements.
  • Now add 5 feet (2 1/2 feet per side) to the length and to the width for the apron (see the illustration below) on a small pond. (Length x Width is less than 1000 sq. ft.). Add 10 feet for the apron and trench on a large pond.
  • OR, If the pond has already been dug, measure across the bottom (length & width) and add material for the apron.
