Why Does The Game Not Match Exactly?

Some games label FOV differently, clamp values, use a custom projection or apply their own aspect scaling. This tool uses standard rectilinear geometry.

The converter uses rectilinear perspective. Confirm whether your game exposes horizontal, vertical, or a 4:3-based FOV before copying the result. Curved displays and game-specific projection corrections need the game's own calibration model.

What Is the Gaming FOV Converter?

The Gaming FOV Converter translates rectilinear horizontal and vertical field of view and carries the view to a new display aspect ratio. It can preserve vertical FOV for Hor+ behavior or preserve horizontal FOV and displays the target frame geometry.

How It Works

Enter the game's stated FOV and axis, choose source and target aspect ratios, then select which axis the conversion should preserve.

When to Use It

Use it when moving between 4:3, 16:10, 16:9, ultrawide and super-ultrawide displays or comparing games that label different FOV axes.
