The tree, which partially stood in the front yard of a private residence, also had a 20-foot circumference and (until mid-2008) a 93-foot crown spread.

The average crown spread was 176 feet and the total height was 80 feet.

The original parent tree (located on a roadside in Ohio) is already over 20 m high, with a slightly greater crown spread.

A tree has three crucial measurements: height, trunk circumference and crown spread.

The two values are averaged to calculate crown spread.

The crown spread is the twice the average of all of the spokes.

These three basic parameters can be expressed as a ratio of height to girth to average crown spread.

Average crown spread can be determined with a simple formula:

If these values are relatively close, simply averaging the two axis to obtain an average crown spread.

The diameter of each disk can be expressed as some fraction of the average crown spread.
