WebUse of diameter tapes. Diameter tapes are used to measure tree stems (trunk or bole); other parts of trees such as branches and roots; and logs (cut stems).Standard Diameter Height (SDH) is the height at which tree diameter is measured, and is normally called diameter at breast height (DBH). DBH is measured at a fixed height of 4.5 feet (1.4 m) … WebThis height is considered “breast height.” At this height, measure around the tree trunk to get its circumference. To calculate the tree’s diameter, divide the circumference by Pi, which is approximately 3.14. In the example shown, this tree has a circumference of 41 inches and a diameter, or DBH, of 13.1 inches.
