What is standard FOV in competitive FPS games?

Standard 16:9 horizontal FOV is typically 90° to 103° (equivalent to approximately 59° to 71° vertical FOV).

Understanding Your Results

Calculates exact equivalent FOV degrees across standard 16:9, 21:9 Ultrawide, 32:9 Super Ultrawide, and Vertical FOV (vFOV).

Practical Guidance & Next Steps

Games like CS2/CoD use Horizontal FOV based on 16:9, whereas Overwatch and Rainbow Six Siege use Vertical FOV.

What is this?

A gaming hardware utility that calculates Field of View (FOV) scaling across monitor aspect ratios.

How does it work?

1. Enter target FOV angle (in degrees). 2. Select measurement axis (Horizontal or Vertical). 3. Select your display ratio (16:9, 21:9, 32:9) to view matching FOV values.

Why use it?

Maintains identical visual scale and muscle memory when upgrading from 16:9 to Ultrawide monitors.

Technical Scope & Calculation Limitations

Uses standard rectilinear lens projection trigonometry.

Frequently Asked Questions

If a game locks Horizontal FOV rather than Vertical FOV, wider screens can crop the top and bottom of your view. Converting to a matching vertical FOV restores your sightlines.
