Working out the size of your pond

When measuring your pond, bear in mind that your results will probably be an approximation: It's unlikely that your pond will have vertical sides, the bottom wont be flat and in most cases the width and length measurements will be an average. However it's still important to use it as a guide especially when looking for a pond pump, filter or using treatments.

To find the average length measure across the length of the pond at three points, add the values together and divide by three. Repeat the same process to find the average width and depth.

Once you have your measurements you can calculate your pond volume here.
