Tree Height Calculator

Angle method is most accurate and works any time. Shadow method is easiest but requires sunshine and flat ground. Stick method needs only a straight rod and works on slopes.
If the tree grows on a slope, choose whether its base is higher or lower than where you stand.
Measure along the ground from where you stand to the base of the tree. Use a tape measure, rangefinder, or paced estimate.
m
Tilt your phone or clinometer upward until the crosshair lines up with the tip of the tallest branch. Record the angle displayed.
degrees
Only needed when the tree base is above or below you. Tilt the clinometer down (or up) to the base and record the angle.
degrees
Your eye level above the ground. Typical adults measure about 1.55-1.75 m (5.1-5.7 ft). Set to 0 if you are measuring from ground level.

Estimated tree height: 18.4 m (60 ft / 18 m)

  • At 18.4 m this is a medium-sized tree, typical of a mature oak, maple, or ash in a park setting.
  • This is roughly equivalent to a 6-storey building (assuming 3 m per floor).
  • The angle method is the most accurate field technique. Keep the distance roughly equal to the expected tree height for the best angle range (30-60 degrees).
  • The portion of the tree above your eye level is 16.8 m. Adding your eye height gives the full tree height.

Next stepFor professional arboricultural surveys, confirm the measurement with a laser hypsometer or a second method, and record the slope of the ground to apply the appropriate terrain correction.
