**measuring**tape,

**measure**4.5 feet up the

**trunk**of the

**tree**from the ground. Use a thumb tack to mark the height on the

**tree**. Wrap your string around the

**tree trunk**at 4.5 feet. Make sure the string is straight and tight around the

**trunk**, and mark or cut the circumference on the string.

In this way, what is the diameter of a tree trunk?

Trunk diameter on large trees is measured at “breast height” which is 4-1/2 **feet** above the ground, and is more commonly referred to as DBH or Diameter Breast Height. To find the DBH, stand next to the trunk of the tree and measure at 4.5 **ft**. above ground. Wrap a measuring tape around trunk and make sure tape is level.

One may also ask, what does the diameter of a tree mean? A **tree's diameter is** used to describe the **tree's** size, calculate its fertilizer requirements and determine the **tree's** potential value as a source of wood. For this reason, the **diameter of a tree is** often referred to as its DBH, or **diameter** at breast height.

Consequently, what is the circumference of a tree?

**Circumference**: Measure around the trunk of the **tree** at four and a half feet (4.5') above the ground on the **tree's** uphill side (if not on even ground). If the **tree** forks below or bulges at 4.5', measure the **circumference** where the **tree** reaches normal size or tapers below the 4.5' foot point.

What is the height of a tree?

The **height of a tree** would be the **height** of its root node, or equivalently, the depth of its deepest node. The diameter (or width) of a **tree** is the number of nodes on the longest path between any two leaf nodes. The **tree** below has a diameter of 6 nodes.
