Sim Racing FOV Calculator
Enter your screen size, aspect ratio and how far your eyes are from the screen. Get the geometrically correct vertical and horizontal field of view for sim racing, and for triple screens the angle to turn the side monitors.
Frequently asked questions
Why does the correct FOV look so zoomed in?
Most games default to a wide view so you can see more. The correct FOV makes the screen act like a window, so the car, speed and distances appear at their real size. It helps judge braking points and corner speed; most drivers get used to it in a few sessions.
Vertical or horizontal FOV?
It depends on the game. Assetto Corsa, Assetto Corsa Competizione, rFactor 2 and Le Mans Ultimate ask for vertical degrees. Others ask for horizontal degrees or use their own scale or slider. Check what your game's setting means before entering the number.
How do I set up triple screens?
Turn each side screen inwards by the angle shown so it faces your eyes square on, then use the triple-screen setting in your game with the same screen size, distance and bezel width. The total horizontal view is about three times one screen's.
How do I measure the distance?
From between your eyes to the centre of the screen, sitting as you drive. Closer screens give a wider correct FOV, which is why rigs put the monitor just behind the wheel.
