FOV Calculator for Sim Racers

Easily calculate the correct FOV (Field of View) and triple screen angles for a variety of racing simulators including Assetto Corsa, iRacing (hFOV), Assetto Corsa Competizione, RaceRoom, F1, Project Cars and more.


How to use: Input your monitor and distance measurements, being sure to know the screen ratio of your monitor (this makes a really big difference!)

Understanding Your FOV Result

Once you’ve entered your monitor measurements and seating position, you’ll see a list of FOV (Field of View) values for various sim racing games. These numbers represent the optimal angle of vision for your setup, helping to create a more immersive and realistic driving experience.

A properly set FOV ensures that objects in the game appear at the correct size and distance relative to your real-world perspective. This can significantly improve your spatial awareness on the track, allowing for better judgement of corners, braking points and overtaking opportunities.

For most simulators, you’ll see a horizontal FOV (hFOV) value. This is the side-to-side angle of vision and is typically what you’ll need to input in your game settings. Some games, like Assetto Corsa, use vertical FOV (vFOV) instead, which represents the top-to-bottom angle.

FOV Settings for iRacing Users

For iRacing, you’ll want to use the hFOV value listed under “Project CARS 1/2”. Despite the different game name, this calculation method aligns perfectly with iRacing’s FOV settings. Simply input this number into the FOV setting in iRacing’s graphics options.

Remember, while a correct FOV might initially feel unusual if you’re used to a wider, unrealistic setting, give yourself time to adjust. Many sim racers report improved consistency and faster lap times after adapting to a properly calculated FOV. Correct FOV means better laptimes!

If you have a triple screen setup, pay attention to the “Triple Screen Angle” value in the calculator results. This helps you set up the correct angle between your monitors for a seamless view across all three screens.

Ultimately, these calculations provide a strong starting point. Feel free to make minor adjustments based on personal preference, but try to stay close to these values for the most authentic driving experience.
