Diameter at breast height

Measurement of tree circumference, the tape calibrated to show diameter, at breast height, making sure that the tape is perfectly level and that the tape is not kinked, so as not to skew the reading of the diameter.

Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements.

Electronic calipers can measure diameter at breast height and send measured data via Bluetooth to a field computer.

Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately 1.3 m (4.3 ft) above ground.[1][2]
