Vertical Field of View Calculator

Vertical Field of View Calculator calculator can be used to calculate the vertical field of view for a given eye height, distance to the object, and object height. This is useful for photography, film production, and visual measurements.

Calculation Formula

FOV = 2 * arctan((Object Height / 2) / Distance) + arctan(Eye Height / Distance)

Where:
FOV = Vertical Field of View (degrees)
Object Height = Height of the object being viewed
Distance = Distance from viewer to the object
Eye Height = Height of the viewer's eyes from the ground

Vertical Field of View Calculator Calculator Usage Guide

Learn how to use the Vertical Field of View Calculator calculator and its working principles

How to Use This Calculator

  1. Enter the height of your eyes from the ground in meters (e.g., 1.5 meters).
  2. Enter the distance from you to the object you're viewing in meters.
  3. Enter the height of the object you're viewing in meters.
  4. Click the "Calculate" button to compute the vertical field of view.
  5. The result will be displayed in degrees.

Principle of Calculation

This calculator uses trigonometry to determine the vertical field of view. The formula accounts for both the height of the object and the observer's position.

Applications

  • Photography: Determining the angle of view for landscape shots
  • Film production: Setting camera angles for optimal framing
  • Architecture: Planning viewing angles for buildings
  • Navigation: Calculating visibility ranges in surveying

Example

If you're standing 10 meters away from a tree that is 5 meters tall, and your eyes are 1.5 meters above the ground, the calculator will determine that you can see approximately 26.57 degrees of the tree's height vertically.
