Vertical Field of View Calculator

Vertical Field of View Calculator calculator can be used to calculate the vertical field of view (FOV) based on the height of the observer and the distance to the object. This is useful in fields such as photography, astronomy, and virtual reality.

Input Parameters

Calculation Results

Calculation Formula

FOV = 2 * arctan((observerHeight / 2) / distance)

Where:
FOV = Vertical Field of View (degrees)
observerHeight = Height of the observer from the ground (meters)
distance = Distance from the observer to the object (meters)

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 the Calculator

  1. Enter the height of the observer from the ground in meters.
  2. Enter the distance from the observer to the object in meters.
  3. Click the "Calculate" button to compute the vertical field of view.
  4. The result will be displayed in degrees.

Principle of Calculation

The vertical field of view is calculated using the formula:

FOV = 2 * arctan((observerHeight / 2) / distance)

This formula assumes that the observer is looking directly at the top of the object, and the object is at a perpendicular distance from the observer.

Applications

This calculator is useful in various fields such as:

  • Photography: Determining the angle of view for capturing landscapes or buildings.
  • Astronomy: Calculating the field of view for telescopes or binoculars.
  • Virtual Reality: Designing VR experiences with appropriate field of view settings.
