How FOV Calculator Works

Conversions between horizontal, vertical, and aspect-ratio-based FOV

Convert field of view values between different measurement types used by different games, accounting for your monitor's aspect ratio.

  1. 1

    Step 1

    Enter your current FOV value

  2. 2

    Step 2

    Select the FOV type (horizontal or vertical)

  3. 3

    Step 3

    Choose your aspect ratio

  4. 4

    Step 4

    View converted FOV values for different systems

Use Cases

Matching FOV settings across different games

Optimizing for your monitor and seating distance

Reducing motion sickness from wrong FOV

Transferring settings to new monitors

Tips

  • 1

    Higher FOV sees more but targets appear smaller

  • 2

    90-110 horizontal FOV is common for PC gaming

  • 3

    Console games often use lower FOV defaults

  • 4

    Too high FOV can cause fisheye distortion

Common Mistakes

  • Not knowing if game uses vertical or horizontal FOV

  • Setting FOV too high causing distortion

  • Not adjusting FOV when changing monitors

  • Copying pro settings without understanding why

Frequently Asked Questions

What FOV should I use?
Most PC players prefer 90-110 horizontal FOV. Lower if you sit far from the screen, higher if close. Find what feels natural and doesn't cause motion sickness.
Does FOV affect performance?
Higher FOV renders more of the world, which can slightly reduce FPS. The impact varies by game and is usually minimal.
Why do games use different FOV systems?
Some use horizontal FOV (based on screen width), others use vertical (based on height). This affects how FOV changes with aspect ratio.
