Tree Height Calculator
Calculate living tree height using clinometer angles (trigonometry) or the stick method.
Input Parameters
Enter details for calculation.
Estimated Tree Height
Expert Tip
For best accuracy with the trigonometry method, stand at a distance roughly equal to the estimated height of the tree.
Calculation Methodology & Details
Formula
Angle to base is subtracted. If looking down to the base, ฮธ_bottom is negative, making -tan(ฮธ_bottom) positive, which adds the eye height. Make sure angles are measured in degrees.
