Calculation Formula

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

Where:
FOV = Vertical Field of View (degrees)
Object Height = Height of the object (meters)
Distance = Distance to the object (meters)
Eye Height = Height of the observer's eye (meters)

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

How to Use the Calculator

  1. Enter the eye height in meters. This is the height of your eyes from the ground when you are looking at the object.
  2. Enter the distance to the object in meters. This is the horizontal distance from you to the object.
  3. Enter the height of the object in meters. This is the vertical height of the object you are observing.
  4. Click the "Calculate" button to compute the vertical field of view.
  5. The result will be displayed in degrees.

Working Principle

The vertical field of view is calculated using trigonometric functions. The formula used is:

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

Where:

  • FOV = Vertical Field of View (degrees)
  • Object Height = Height of the object (meters)
  • Distance = Distance to the object (meters)
  • Eye Height = Height of the observer's eye (meters)

This formula calculates the total vertical field of view by considering the angles subtended by the top and bottom halves of the object at the observer's eye height.
