In the case of a kidney shaped pond you would form a rectangle around all outer perimeters and estimate a percentage of what is dry land. This value should be multiplied by 1000 to give a value in litres.Ĭomplex ponds such as kidney shapes will need to be closely estimated. The surface area is then multiplied by the pond depth to give the volume in m3. You will need to firstly work out the surface area of the pond by multiplying the radius by itself and then by Pi ( πr² ). Rectangular pond: 3m L x 1.5m W x 0.75m DĬircular ponds are calculated differently.
The volume in m3 then needs to be multiplied by 1000 to give a measurement in litres. The simplest way to calculate your pond volume would be to work out the surface area in m2 (square metres) and then multiply it by the depth to produce m3 (cubic metres). Volume Calculator View our Pond Filters Wizard here. Below the calculator is a link to our Pond Filters Wizard which will automatically select the right filter for your pond, once you know the water volume. Most pond filter choices are based around Litres (not gallons) so make a note of your volume in Litres for future use. Note: This calculator calculates the total area within the red line.
The calculator uses imperial measurements for the calculations. Includes results for the pool surface square footage and a reasonable close perimeter measurement. For circular ponds, calculate as a square, then reduce the pond volume stated by 20% (1/5th).
