1 cubic meter = 1,000 litres = 264.17 gallons
Tip: For complex shapes, break into multiple sections
Standard rectangular pond with straight sides. Perfect for formal ponds and raised beds.
Inputs: Length × Width × Depth
Equal-sided rectangular pond. Common for small garden features and koi ponds.
Inputs: Side × Side × Depth
Circular pond from edge to edge. Classic choice for wildlife ponds and fountains.
Inputs: Radius × Depth
Elliptical or egg-shaped pond. Natural-looking option for landscape ponds.
Inputs: Length × Width × Depth (calculates as an ellipse)
Part of a circle cut by a straight line. Use for ponds against walls or partial circles.
Inputs: Full circle radius × Height from chord to arc × Depth
Wedge-shaped section from center to edge. Like a slice of pie from the middle.
Inputs: Radius × Angle in degrees × Depth
Pie slice that doesn't reach the center. For corner ponds or sections with an island.
Inputs: Outer radius × Inner radius × Angle × Depth
Enable "Variable Depth" checkbox for ponds with sloped bottoms. Perfect for natural ponds with shallow plant areas and deeper fish zones.
Calculates volume using average depth: (Shallow + Deep) ÷ 2
This calculator provides estimates only and should not be relied upon for critical applications such as chemical dosing, medication, or any treatment that could affect pond life. Actual pond volumes can vary due to irregular shapes, construction variations, and measurement inaccuracies.
Always: • Double-check calculations manually • Start with lower chemical doses than calculated • Consult product instructions and professionals • Test water parameters regularly
