Calculate the right FOV for your monitor and seating distance.
Physically correct FOV depends on screen size and viewing distance. For a 27-inch monitor at 60 cm, the mathematically correct horizontal FOV is about 53 degrees, but most players prefer 90-110 for competitive games. Enter your setup above to get your exact physical FOV plus a game-type offset.
Inputs: Monitor diagonal (inches or cm), viewing distance, aspect ratio, and game type.
Output: Recommended FOV in degrees, horizontal and vertical, with a game-type adjustment.
Limitations: Some games (CS2, Valorant) lock FOV to the aspect ratio and ignore custom values. Game-type offsets are common starting points, not fixed recommendations.
Physical and competitive FOV values for common monitor sizes and distances.
| Monitor | Distance | Physical HFOV | Competitive range |
|---|---|---|---|
| 24-inch 16:9 | 50 cm | 56° | 90-105 |
| 24-inch 16:9 | 60 cm | 48° | 90-105 |
| 27-inch 16:9 | 50 cm | 62° | 90-110 |
| 27-inch 16:9 | 60 cm | 53° | 90-110 |
| 27-inch 16:9 | 70 cm | 46° | 90-110 |
| 32-inch 16:9 | 60 cm | 61° | 95-110 |
| 34-inch 21:9 | 60 cm | 67° | 95-110 |
Physical HFOV is the mathematically correct angle for your screen and distance. Competitive range is what most players use in adjustable-FOV games like Apex, CoD, and Overwatch 2.
Field of view determines how much of the game world you see at once.
Every game renders its world through a virtual camera. The FOV setting controls how wide that camera's lens is. Set it too low and you're looking through a tunnel. Set it too high and everything fish-eyes at the edges.
The correct FOV is the one that matches the physical angle your monitor occupies in your vision. A 27-inch monitor at 60 cm covers about 53 degrees horizontally. Setting in-game FOV to that value means objects appear at their true size. Most competitive players add 40-60 degrees above the physical value for peripheral awareness.
Most competitive players add 5-10 degrees on top of the calculated value. The slight distortion is worth the extra peripheral awareness in fast games like Apex or Warzone.
Games handle FOV differently. Knowing which type your game uses matters.

How the FOV calculation works.
Formula: HFOV = 2 × arctan(screen_width / (2 × distance)). The physical monitor width is derived from the diagonal size and aspect ratio. This is standard trigonometry, not a game-specific approximation.
Game-type offsets: FPS competitive adds a common offset for peripheral awareness. Tactical shooters (CS2, Valorant) lock FOV by aspect ratio. Sim racing uses exact physical FOV with no offset.
