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.
Use the Pond Pump Flow Calculator
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.
Use the Pond Liner Size Calculator
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.
Use the Waterfall & Stream Flow Calculator
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.
Use the Pond Rock & Gravel Calculator
Pondless Waterfall Basin Calculator
Estimate water in motion in a Pondless Waterfall stream, then compare standard and higher-capacity basin storage using PondScape AquaMatrix Small or Large modules.
Use the Pondless Waterfall Basin Calculator
Pipe Friction & Total Dynamic Head Calculator
Estimate total dynamic head by combining vertical lift, straight-pipe friction, and fittings allowance. Use the result to compare against a pump’s performance curve before selecting equipment.
Use the Pipe Friction & Total Dynamic Head Calculator
Wetland / Bog Filter Sizing Calculator
Estimate a recommended planted-wetland footprint from water-feature type, shape, length, and width. The tool accounts for an 80% adjustment for natural or irregular shapes and provides a planning estimate for PondScape AquaMatrix modules.
Use the Wetland / Bog Filter Sizing Calculator
Lake & Pond Aeration Sizing Calculator
Estimate a starting number of diffuser zones for a typical dirt-bottom pond or lake using surface area and average depth. The tool recommends PondScape Faux Rock or Cabinet Aeration Systems and flags shallow-water review.

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.
