FOV Calculator
Use Optimal FOV for physical setup math or Convert for horizontal/vertical conversion.
What is Field of View?
Field of View (FOV) is the visible angle of the virtual world on your monitor. Lower FOV feels zoomed in with bigger objects but less peripheral awareness. Higher FOV shows more surroundings but distant targets appear smaller. The ideal value balances awareness, scale, and visual comfort.
hFOV vs vFOV
hFOV is horizontal field of view (left-to-right). vFOV is vertical (top-to-bottom). Games ask for one or the other — use converter mode to translate between them correctly instead of copying raw numbers.
FOV Ranges
- Below ~75 hFOV: Very narrow, cinematic zoom, limited side vision.
- ~75 to ~85 hFOV: Narrow to moderate, usable on desk setups.
- ~85 to ~110 hFOV: Balanced range for most single monitor users.
- ~110 to ~125 hFOV: Wide view with stronger edge stretching.
- Above ~125 hFOV: Very wide, can look unnatural unless setup supports it.
FOV for Sim Racing vs FPS
Sim racing: Geometry-based FOV is best for realistic scale. This calculator uses your real monitor specs and distance to derive recommended values. Single-monitor rigs use lower hFOV than triple setups.
FPS games: Wider FOV helps map awareness and target acquisition, but too wide makes long-range tracking harder. Start from a comfortable base and adjust in small increments.
Frequently Asked Questions
Why does one game's FOV not match another?
Games use different FOV definitions (horizontal vs vertical) and aspect assumptions. Use converter mode to translate correctly.
Should I always use physically calculated FOV?
For sim racing, physical FOV is best for realism. For FPS, some players prefer slightly wider for awareness. Use the physical value as a baseline, then tune for comfort.
Is iRacing FOV the same as other sims?
Many sims use compatible formats, but UI labels differ. Always confirm the expected FOV type before applying values.
