About Nursery Plants Pots
Nursery containers come in a number of sizes. Oftentimes, the particular plant and its current size determine the pot sizes used in nurseries. For instance, most shrubs and trees are sold in 1-gallon (4 L) pots – otherwise known as a #1 pot size.
Grade of Nursery Plant Pots
In addition to the various pot sizes, some nursery growers include grading information. As with the variations among sizes, these too may vary among different growers. These are usually dependent on how a particular plant has been grown (its conditions). That said, the most common grades associated with plant pots are:

How big are trees in containers?
You will find trees, shrubs, and evergreens in sizes as small as #5 containers and as large as #25. Once you surpass a #25 Container size, shrubs and evergreens measure by height (in inches or feet), and trees measure in caliper.
What is a caliper tree?
Caliper is the measurement of the diameter of a tree trunk, in inches. These trees are planted as babies in farm fields and grown to more mature sizes. When they’re harvested, the root zone is wrapped in burlap, set in a wire cage to protect the root mass, and safely held together with twine – called balled & burlapped (B&B) plant stock. Johnson’s Nursery measures caliper at 6” above the root flare. In our inventories, you’ll see 1.5” caliper (the smallest size we’re willing to sell a field-grown tree) and up. A homeowner is likely able to transport a smaller tree from 1.5” to 2.5” caliper without professional help. We recommend delivery beyond that size.

Plants listed in caliper or height sizes are raised in the ground on the farm - they sit for many years (before you're aware they exist) to become a larger - instant gratification - size.

ANSI
The American National Standards Institute -- or ANSI -- now regulates pot sizes to standardize what size pot you are getting. Even indicating the pot's width, such as a 10-inch pot, doesn't tell you what the volume -- and therefore the potential root size -- of the pot is.
Large Pot Classes
Manufactured pots have to fall within the ranges that define their classes. This allows for variations in heights and widths from different manufacturers to suit different growers needs, but still standardizes the volume. Manufacturers indicate large container classes by the pound sign, #, followed by a number 1 through 100.
Smaller Pot Sizes
Small plant containers, usually holding perennials or annuals, are indicated by "SP" followed by the length of the side of the pot for square pots -- or the diameter, for round pots -- measured in inches.
What Size Pot to Buy
Nurseries sell annual plants in the #SP 1 through 5 sizes. The larger the pot, the more room the roots have had to grow and the sooner the plant will be able to flower. You can find lower-priced perennials in #SP 4 or #SP 5 pots, but they may not bloom the first year.
