Sim Racing FOV Calculator

Calculate optimal field of view for iRacing, Assetto Corsa, rFactor 2, and other sims based on screen size and viewing distance.

🏎️ FOV formula: FOV = 2 × arctan(0.5 × screen_width / viewing_distance). Correct FOV creates 1:1 real-world scale, improving depth perception and consistency.

💡 Pro tip: Most sim racers use FOV between 45°-65° for single screen. Triple screens allow wider FOV (120°-180°) for peripheral vision. Sit as close as comfortable to the screen.
