Stop overshooting corners and locking brakes. Here is how to measure eye-to-panel distance, compute exact mathematical vFOV and hFOV angles, and set up triple monitor side arcs for Assetto Corsa and iRacing.
Sit in your driving cockpit in your standard racing posture with hands on the wheel. Measure with a tape from the bridge of your nose directly to the center of your primary monitor screen in centimeters.
Use the formula vFOV = 2 * arctan((Screen Height in cm / 2) / Distance in cm) * (180 / π). For a 27-inch 16:9 screen at 60cm distance, this yields exactly 28.4° vFOV.
Angle your left and right side monitors so their screen planes point perpendicularly toward your eyes. Calculate the side angle using the formula SideAngle = 90° - (Total_hFOV / 4), ensuring side mirrors appear in your true peripheral vision.
Measure the physical bezel width of adjacent monitor bezels combined (typically 10-15mm). Enter this value in Assetto Corsa or iRacing to offset pixels behind the plastic seam, ensuring guardrails connect seamlessly.
Test, convert, and benchmark your gaming settings right in your browser:
Most arcade default camera angles are artificially wide (60°-70° vFOV) to create an exaggerated sensation of speed. Once your eyes adapt to true 1:1 FOV, corner apexes, braking distances, and tire slip angles become predictable and consistent.
Yes! Single curved ultrawide monitors (like 34" or 49" panels) use a single continuous arc radius (e.g. 1000R or 1500R) rather than segmented angles, which our calculator handles automatically.
