Pond Volume Calculator
It is very important to know the volume of your pond. You will need the volume in order to calculate things like, how much salt to add or how much medication to put in your pond when treating a sick fish, for example. It can also be very useful when selecting suitable equipment for your pond set up. Many pumps and filters are rated for a maximum pond volume and will not be able to do their job if they are fitted to a system where the volume of the pond is too large.
Use our pond water volume calculator below to see how much water your pond holds. Simply input the length, width, and depth of your rectangular pond or the diameter and depth of your circular pond. Select the measurement units you have used, meters or feet, and click calculate. The calculator will then give you the volume of your pond in both litres and imperial gallons.
If you have an irregularly shaped pond that is not round or rectangular, or you want to see how to do the calculations yourself, have a look at our blog post How to Calculate the Water Volume of your Garden Pond. The blog article also talks about how to calculate the volume of your pond using a water meter or by adding salt to the pond and measuring the salinity, so take a look if you are interested in these methods.
