Small trees
Smaller nursery-sized trees that are readily transplanted are usually measured by their "trunk caliper" (diameter) anywhere from 6 to 12 inches above the soil surface, depending on their caliper size. Example: a 2 to 2-1/2 inch caliper tree is measured 6 inches above the ground.

Diameter is the relationship between the circumference of the a circle (in this case the trunk) and the number π (3.14).
It can be expressed as: Diameter = Circumference ÷ π
Example:
- The circumference of the tree is measured at 46.5 inches,
- Diameter = 46.5 ÷ 3.14
- Diameter = 14.8
