Plan with confidence
Use these tools to get quick, practical estimates before you plan or shop for your pond. They are a helpful starting point, but final equipment choices should always be confirmed against the specific product’s own specifications.
Pond Volume Calculator
Estimate how much water your pond holds from its shape and dimensions. Knowing your pond’s volume is the first step toward sizing pumps, filtration, and treatments.
Use the Pond Volume Calculator
Pond Pump Flow Calculator
Estimate the pump flow rate your pond may need based on pond volume, desired turnover time, vertical lift, and optional waterfall flow targets. Always check a pump’s actual performance curve before making a final selection.

Pond Liner Size Calculator
Estimate the liner size you need from your pond’s length, width, maximum depth, and an edge overlap allowance. Ponds with shelves, slopes, streams, or irregular shapes typically need extra material beyond this baseline.

Waterfall & Stream Flow Calculator
Estimate a starting waterfall-flow target from your spillway width, before accounting for pump lift and plumbing losses. Confirm final pump selection against its performance curve at the total dynamic head.

Pond Rock & Gravel Calculator
Estimate boulders and river gravel for a standard pond using length, width, and maximum depth. Planning formulas reference dense natural stone such as granite or weathered limestone.

Results from these calculators are planning estimates. Actual pond conditions and equipment performance vary, so confirm final equipment choices against the manufacturer’s product specifications.
