Field units
Trunk input

Measure the trunk girth at standard measuring height.

If you measure DBH instead, the page converts it to circumference for scoring.

Use the same unit system selected above.

Average crown spread is the mean of the widest spread and the widest spread at right angles.

Why this page is useful

Big-tree scoring usually sounds simple until you have mixed notes, a diameter instead of circumference, or crown measurements scribbled separately. This page keeps the actual score formula visible and translates field notes into a clean total.

  • Targets searches around champion tree calculator, big tree points, and how to measure a tree for nomination.
  • Keeps metric input practical even though the common U.S. points system is scored in inches and feet.
  • Shows the score breakdown so measurement disputes are easier to inspect.
