How to Use Angle of Elevation Calculator
The Angle of Elevation Calculator is a flexible right-triangle solver designed to calculate heights, distances, and elevation angles.
- Pick what to solve for — Angle of elevation, vertical height, or horizontal distance.
- Enter the two known values — The calculator hides the field you are solving for.
- Keep units consistent — Use the same unit (meters, feet) for height and distance.
- Read the result — View the calculated value, angle in degrees and radians, and the direct line-of-sight distance.
Formula & Theory — Angle of Elevation Calculator
The Angle of Elevation Calculator uses standard trigonometry for right-angled triangles:
tan(θ) = vertical / horizontal
vertical = horizontal × tan(θ)
horizontal = vertical / tan(θ)
slant = √(vertical² + horizontal²)| Symbol | Meaning |
|---|---|
| θ | Angle of elevation (from horizontal upwards) |
| vertical | Height of the target above eye level |
| horizontal | Horizontal distance to target base |
| slant | Direct line-of-sight (hypotenuse) distance |
Eye Level Consideration
In real-world observations (e.g., measuring a tree or building), remember to add the observer’s eye height to the calculated vertical height to find the total height above ground.
