Simulator Field Of View Calculator

Measure your rig, check the viewing geometry and apply the right setting in your simulator. Everything below is calculated from your own measurements, not from assumed hardware specifications.

Step 1 — Choose your simulator

Unverified mapping

Display configuration

Screen orientation

Applies to every screen in this arrangement.

VR headsets

Headset projection is controlled by the headset and its runtime, so this monitor calculator does not produce a replacement VR field-of-view value. Flat-screen maths does not apply to a headset. Set your seating position and scale inside the game's VR options instead.

Ultrawide and super ultrawide describe aspect ratios, not separate projections. Each can be flat or curved, and every mode shares the same geometry engine.

AI Setup Assistant

Optional assistance for filling calculator inputs. The field of view is always calculated by the geometry engine.

AI is off by default and sends nothing until you switch it on. Manual setup and monitor lookup remain available.

Measurements

Measure from between your eyes, in your normal driving position, to the centre of the centre screen surface. Not from the seat or wheel.

Screen

88 researched models with maker sources (checked 2026-09-29). Not a popularity ranking, price or stock list.

Width and height are derived from the diagonal and aspect ratio (813 mm diagonal). Manufacturer active-image dimensions or your own measurements are more accurate than rounded marketing sizes.

mm

Active image to housing edge. Shown on the diagram for scale — a bezel around a single screen never changes the field of view.

Shortcuts are typical values, not verified monitor-model specifications.

Schematic only, drawn to relative scale. Drag the blue handles to change distance or fold angle, or type exact values in the inputs. It is not a substitute for physical measurement. Side angle 0° means all panels are in one flat plane.Thick coloured line: lit (active) imageThin grey segments: bezel — black border plus casingSpace between casings: physical gapDot: your eye, with sightlines to the image edges

Schematic only. Eye height is treated as level with the centre of the screen, which is the assumption used by the calculations.

Interactive 3D rig view

Click a display or the head to highlight it. Drag the head to change eye distance; drag inside the circle to orbit or pan; scrolling moves the page.

Physical measurements, not a single FOV number

This simulator takes measured screen geometry and computes the projection itself. Enter the physical values shown below.

Physical values to enter in game

  • Active image width, centre screen: 708 mm
  • Active image height, centre screen: 398 mm
  • Eye to screen distance: 700 mm

Angle convention: Side monitor angle entered as the rotation of the side panel towards the driver
