Distance to tree

Angle to treetop (degrees)

Eye height

Calculated Output

Tree height 47.455

Formula: height = distance × tan(angle) + eye height

Step-by-Step Breakdown

1. Values used:

2. Distance to tree = 50

3. Angle to treetop = 40 degrees

4. Eye height = 5.5

6. Tree height = 47.455

Did this calculator solve your problem today?

The math behind it

height = distance × tan(angle to top) + your eye height.

50 ft away, 40° up, eye 5.5 ft → ~47.5 ft.

Measure the angle?

Use a clinometer or a phone app to sight the treetop.
