iRacing FOV Calculators

iRacing FOV Calculator
– FOV CALCULATORS – with thanks to David Tucker.
  • Calculators work in cm or mm or inches.
  • Enter your monitors horizontal width and the distance from your eyes to the monitor to calculate the correct field of view for your seating position.
  • Reducing the distance form your monitor to your eyes will increase the field of view.
  • On games that use a vertical FOV instead of a horizontal one, enter the monitors height to calculate the correct FOV.
  • If you have triple monitors configured to render as if they were one large monitor then line the monitors up in a flat row and use the total width of all three monitors to calculate the FOV.
  • If you are rendering a separate image to each monitor, then use the triple monitor calculator below.
  • On a single monitor you want to use the width of the viewable part of the monitor.
  • On a triple monitor, single renderer, setup you want to use the width of the viewable image as well, but include the center bezels.
    That is treat it like one large monitor with some annoying black lines on it.
    Then in your video card you want to enable bezel correction so the central bezels are taken into account when rendering the image.
  • If you choose to render each monitor separately (which I do)
    then only measure the viewable width on the center monitor and don’t apply any bezel correction in your graphics card.
    Typically your graphics card will provide two resolutions to you, one with bezel correction turned on and one without it. The smaller horizontal width is the one without bezel correction.

    I like the distance calculation and I would like to suggest an optional schematics – where the side monitors will be mounted with overlapping the middle monitor bezels … in iRacing that works very easy – you have 2 values – 1 without bezel and 1 with …
    in overlapping you add only 1 bezel to the value without.
