Field of View (FOV) Converter
Convert between Horizontal and Vertical Field of View across display aspect ratios.
70.53°
How It Works
- Applies trigonometric tangent formulas to calculate angular relationships.
Formula & Technical Standard
Horizontal FOV = 2 * arctan(tan(Vertical FOV / 2) * Aspect Ratio)
Practical Example
103 H-FOV on 16:9
Input: 103° Horizontal
Output: 70.53° Vertical FOV
Matches geometry in games using vertical FOV (R6 Siege).
Frequently Asked Questions
Why use Vertical FOV?
Vertical FOV keeps framing constant while ultrawide screens expand horizontally.
