What is the difference between Horizontal and Vertical FOV?

Horizontal FOV measures peripheral view angle horizontally across the screen, whereas Vertical FOV measures top-to-bottom viewing angle. Games like Overwatch and BF use Vertical FOV, while Valorant uses fixed 103° Horizontal FOV.

What FOV does Valorant use?

Valorant locks Horizontal FOV strictly to 103° on 16:9 widescreen displays (which equals ~70.53° Vertical FOV).

Does a higher FOV give an advantage?

Higher FOV gives broader peripheral vision to spot flankers, but makes central targets appear smaller and harder to hit at long range.

How do I convert between Horizontal and Vertical Field of View (FOV)?

Direct Answer: To convert Horizontal FOV to Vertical FOV: V-FOV = 2 × atan(tan(H-FOV / 2) / Aspect Ratio) × (180 / π). Conversely, H-FOV = 2 × atan(tan(V-FOV / 2) × Aspect Ratio) × (180 / π).

Pro Tips & Best Practices

103° Horizontal FOV (16:9) is the esports standard across Valorant and Overwatch.
In CS2 and Apex Legends, setting FOV to 90 uses a 4:3 base, which equals ~106.3° on 16:9 widescreen monitors.
