The Visual Angle Calculator is a valuable tool used to determine the visual angle subtended by an object based on its size and the distance from the observer. It helps in understanding how large or small an object appears from a specific viewpoint, aiding various fields such as vision sciences, optics, and design.
Formula of Visual Angle Calculator
The formula used for calculating the visual angle is:
θ = 2 * arctan(S / (2 * D))
Where:
- θ is the visual angle in degrees.
- S represents the size of the object.
- D stands for the distance from the observer to the object.

Example of Visual Angle Calculator
Let's consider an example to illustrate the application of the Calculator. If an object measures 2 meters in size and is placed 6 meters away from the observer, the visual angle can be calculated using the formula mentioned earlier.
Substituting the values into the formula:
θ = 2 * arctan(2 / (2 * 6))
Upon calculation, the visual angle is determine to be approximately 16.70 degrees.
