If your sim feels “fast but floaty,” if corners look stretched, or if braking zones feel weirdly far away, your FOV is probably off. FOV is one of the most important settings in sim racing - and one of the most misunderstood. Most drivers either crank it up for visibility or copy someone else’s number without realizing that FOV depends on their monitor and their seating distance.
GripDial built a free Sim Racing FOV Calculator that uses your real setup (screen size, aspect ratio, distance, single or triple screens, and even curved monitors) to output correct FOV values for popular sims. It also shows a visual of the viewing cone so you can understand what the number actually represents.
What FOV Actually Means in Sim Racing
FOV stands for Field of View. In sim racing, it is the angle of the virtual world that the game renders through your “camera.” Your monitor is basically a window into that world.
The goal of correct FOV is simple:
- Match the virtual viewing angle to the real-world angle your screen occupies from your eyes.
When FOV is correct, distances look believable. Turn-in points feel more natural. The car’s speed and sense of rotation become easier to judge. When FOV is wrong, the sim can still be drivable - but it becomes harder to be consistent.
Why “Just Turn It Up” Usually Backfires
Many drivers increase FOV to see mirrors, apexes, and side-by-side action. The trade-off is perspective distortion:
- Too wide: objects look smaller and farther away - braking points feel late and speed feels exaggerated
- Too narrow: the view feels zoomed - speed feels slow, and you can lose peripheral context
The most common symptom of too-wide FOV is “I keep overslowing or I miss braking markers.” The most common symptom of too-narrow FOV is “I feel locked forward and I cannot judge rotation.”
Correct FOV is not about comfort alone - it is about giving your brain a consistent visual model of distance and motion.
hFOV vs vFOV – The Reason People Keep Getting It Wrong
Sim racing gets confusing because not every game uses the same FOV type:
- hFOV (Horizontal FOV) - most sims use this
- vFOV (Vertical FOV) - some games and settings use this instead
A number that is correct as hFOV can be wildly wrong if the game expects vFOV. That is why copying a friend’s “72 FOV” can feel perfect in one sim and terrible in another.
GripDial’s calculator outputs both, and labels which games typically use which type, so you can set it correctly the first time.
What the GripDial FOV Calculator Uses
The calculator is built around the things that actually determine correct FOV:
- Aspect ratio (16:9, 21:9 ultrawide, 32:9 super ultrawide, and more)
- Monitor size (diagonal in inches)
- Viewing distance (how far your eyes are from the screen)
- Single or triple screens
- Curved monitor options (with radius input)
- Bezel thickness (for triple setups)
Once you enter those, the tool calculates:
- hFOV - for sims that use horizontal values
- vFOV - for sims that use vertical values
- Recommended triple screen side angle - when triples are selected
Triples – Why the Angle Matters as Much as the FOV
With triple monitors, people often focus only on getting a higher FOV number. The real magic is correct geometry.
If your side screens are not angled appropriately toward your eyes, you can get odd distortions at the seams where screens meet. Even if the FOV number looks “close,” the perspective across the three panels will not line up the way it should.
GripDial’s calculator includes a recommended per-side angle for triples. This gives you a solid starting point so your physical rig matches the camera math.
Curved Monitors – Helpful, But Not “Automatic Correct FOV”
Curved monitors can feel more natural because the edges stay closer to your eyes. But curved setups still need the correct relationship between:
- the monitor’s physical width
- the curve radius (like 1000R)
- your seating distance
That is why the calculator includes a curved option and curve radius input. It gives you a more realistic FOV estimate than treating the monitor as perfectly flat.
How to Use the Calculator in 60 Seconds
- Select your screen ratio (16:9, 21:9, 32:9, etc.)
- Choose single screen or triple screens
- Set your screen size (diagonal inches)
- Set your distance to screen (cm) - measure from your eyes to the display
- If triples, set bezel thickness and apply the suggested angle
- If curved, enable curved and enter your radius
- Copy the output FOV value into your sim - using the correct type (hFOV or vFOV)
After you set it, do a quick sanity check in a familiar car on a familiar track. The view should feel less “gamey” and more like a real driving perspective.
What Changes When FOV Is Correct
Correct FOV will not instantly make you faster by itself, but it usually improves the things that create speed:
- Depth perception - better judgement of distance to apex, curb, and braking markers
- Consistency - less “guessing” because visual cues match reality
- Confidence in traffic - side-by-side spacing becomes easier to read
If you have been driving with an extreme FOV, give yourself a session or two to adapt. Many drivers feel “slower” at first because the speed distortion is gone - then they start braking more accurately.

Conclusion – FOV Is Setup, Not Preference
Once you see FOV as geometry instead of a “comfort slider,” it gets a lot easier. Your monitor has a real size. You sit a real distance away. The correct FOV is the angle that matches those two facts.
GripDial’s calculator makes that quick - then outputs the value in the format your sim actually uses. Less distortion, better distance judgement, and a rig that feels like it is working with you instead of against you.
