(a) Caliper - Caliper refers to the trunk diameter of a nursery stock or younger tree. The measurement is taken 12 inches above the ground.
(b) Diameter at Breast Height (DBH) - Tree dbh is a standard method for measuring the trunk of a standing tree. When measuring dbh, measure approximately 4.5' from the ground up along the trunk. If the tree's branches or bumps interfere with the dbh measurement, take the measurement below the branch or bump. If a diameter tape is not available, measure tree circumference by wrapping a normal tape measure around the tree at 4.5' from the ground, then divide the resulting circumference in inches by 3.14 to determine dbh.
