You'll need some overlap on the pond banks to secure the liner in place, so add an additional 1-1/2 to 2 feet to these figures. For example: For a finished pond that measures 10 ft long x 15 ft wide x 1-1/2 ft deep, you'll need a 15' x 20' liner.The following Pond Sizes are based on 2' depth with 1' overlap for securing:Liner SizePond Sizeandnbsp;Liner SizePond Size8' x 10'-->2' x 4'-->15' x 20'9' x 14'10' x 10'4' x 4'15' x 25'9' x 19'10' x 15'4' x 9'20' x 20'14' x 14'15' x 15' --->9' x 9' --->20' x 25'14' x 19'
