Detailed explanation-1: -Diameter at breast height (DBH) is measured by holding the stick a fixed distance, usually 25 inches (64 cm), from the eye, and at breast height, which in the United States is 4.5 feet (1.4 m) up the bole of the tree. The left side of the stick is flush with the left side of the tree.
Detailed explanation-2: -Hold the stick vertically 25 in. (62.5 cm) from your eye with the lower end approximately at eye level and with the scale for measuring heights facing you. Line up the zero end of the stick with the stump height-the height of the stump if the tree were cut. This is usually not more than 1 ft.
Detailed explanation-3: -Hold the Biltmore stick against the tree at DBH, 25 in. (62.5 cm) from your eye. Make sure the edge of the stick that reads diameter is facing you. Sight past the zero end of the stick and the edge of the tree.
