About This Tool

Field of View (FOV) is the extent of the observable world seen at any given moment. A correct FOV is crucial for an immersive and fair gaming experience. This calculator helps you find the mathematically correct FOV based on your screen size and viewing distance. The advanced Game Converter also allows you to seamlessly transfer your preferred FOV settings between different games, which often use different scaling methods.

How to Use

1. Enter Screen Details: Input your screen's diagonal size, aspect ratio (or a custom one), and your distance from the screen.
2. Review Results: The calculator instantly provides the Horizontal (HFOV), Vertical (VFOV), and Diagonal (DFOV) values, along with a visual representation.
3. Convert for Games (Optional): Use the Game FOV Converter to translate your FOV to a new game's format. Select the 'From' and 'To' games and enter your current FOV value.
