Pond Liner Size Calculator

Use our calculator to determine the size of pond liner needed for your pond. To use this tool, enter the maximum width, length and depth in feet with decimal and not fraction. Example - a maximum depth of 30" would be entered as 2.5 feet. Pond liners are sold in increments of 5 feet. Be sure to round, the values below, to the next 5 feet. Example - a liner of 12' x 24' would require purchasing a 15' x 25' liner. The calculater also determines the approximate total gallons and minimal pump flow rates for proper water movement. Ponds with a heavy fish load will require even higher flow rates.
