This is why some of our containers might be taller or wider but labeled the same size. Plants with deeper roots will need deeper pots, while those with more shallow roots will be fine in a container that’s wide but shallow. At, we strive to match the container to the needs of the plant and choose to measure by volume. So, how do we make sense of it all if there’s no decided system? The answer is to focus on the plant’s needs and the volume over the dimensions or look of the container.ĭifferent nurseries have come up with their own system, often numbering or lettering the pots as they increase in size, while some just generalize and measure by volume instead. Instead, containers are measured by volume (how much soil they can hold) therefore, comparing a gallon of milk to a gallon of soil will look quite different. This is also why there might be several different-looking 1 gallon containers out there.

There is no nursery-wide standard for pot sizes, meaning that container manufacturers can make pots with slightly different dimensions and designs as they see fit.
