Deciding which pot size to use when a plant needs to be up-sized can give someone a headache. Pot sizes often come in different sizes. You will probably find some in inches, some in gallons, and even some in fluid ounces, which can make the process quite confusing.
When the time comes to choose a new pot, you have to keep in mind that the container volume will affect the maintenance. Generally, larger plants would require additional space for roots. Larger, thicker pots or insulated pots can frequently do a better job protecting roots.
Also, the shape you use when planting or up-sizing will matter. Tall containers will work better forplants that form deep root ball such as palms, shrubs, among many others. On the other hand, wide pots are ideal for plants with thin roots such as ferns, succulents, and cacti.
The general accepted standard pots sizes are similar in that the deepness equals the diameter at the rim. Some of the larger sizes are prone to variances in height, width and depth of the pot. See our table of conversion with the standard various sizes and measurements for pot sizes.
