# Visual Angle Calculator

## About Visual Angle Calculator (Formula)

The Visual Angle Calculator is a useful tool that enables users to calculate the visual angle of an object based on its visual size and distance. The visual angle is an important concept in fields such as psychology, vision science, and human-computer interaction.

The visual angle refers to the angular size of an object as perceived by an observer. It is measured in degrees and represents the span of the object as it appears in the visual field. The visual angle is determined by two factors: the visual size of the object and the distance between the observer and the object.

The formula used to calculate the visual angle is as follows:

Visual Angle (degrees) = atan(Visual Size / Distance) * (180 / π)

In this formula, “atan” represents the inverse tangent function, “Visual Size” denotes the size of the object being observed, and “Distance” represents the distance between the observer and the object. The result is then converted from radians to degrees by multiplying it by (180 / π).

By inputting the visual size and distance values into the Visual Angle Calculator, users can quickly obtain the corresponding visual angle. This information can be valuable for various applications, such as determining the legibility of text on a screen, evaluating the visibility of objects in a visual scene, or understanding the perception of size and distance in virtual reality environments.

With the Visual Angle Calculator, users can conveniently compute visual angles, enabling them to make informed decisions and design considerations based on the visual properties of objects.
