Calculate your optimal field of view based on monitor size and viewing distance. Convert FOV between games and find the perfect balance between awareness and precision.
Enter your monitor specifications and viewing distance to calculate the optimal FOV that matches your physical setup. This minimizes distortion and creates natural perspective.
Balanced, natural perspective
Your FOV is in the optimal competitive range (90-110°). Fine-tune based on personal preference.
Field of View (FOV) is the extent of the observable game world visible on your screen at any given moment, measured in degrees. It determines how much you can see horizontally and vertically without moving your view. FOV is one of the most important yet often overlooked settings in PC gaming.
Most games use horizontal FOV, which measures the viewing angle from left to right. Vertical FOV measures top to bottom. The relationship between them depends on your aspect ratio. A 16:9 monitor at 90° horizontal FOV has approximately 59° vertical FOV. Ultra-wide monitors (21:9) maintain the same vertical FOV but have much wider horizontal FOV.
FOV directly affects your gameplay experience, aim precision, spatial awareness, and even physical comfort. Too low FOV creates tunnel vision and can cause motion sickness. Too high FOV provides better awareness but causes fish-eye distortion and makes targets appear smaller. The optimal FOV balances peripheral vision with target clarity and matches your physical viewing setup.
The "perfect" FOV theoretically matches the angle your monitor occupies in your real-world vision. If you sit 60cm from a 24-inch monitor, it occupies roughly 90 degrees of your vision. Using 90° FOV in-game creates a 1:1 relationship between physical and virtual space, minimizing distortion and improving aim consistency. This is why the formula considers both monitor size and viewing distance.
Larger targets, easier to aim at distance, better for controllers
Limited peripheral vision, feels slow, less situational awareness
Console gaming, single-player games, long-range combat
Natural perspective, minimal distortion, good target size
Less peripheral awareness than higher FOV
Tactical shooters, balanced gameplay, first-time PC players
Great peripheral vision, better awareness, competitive advantage
Targets appear smaller, slight edge distortion
Competitive FPS, fast-paced games, aggressive play
Maximum awareness, excellent for ultra-wide monitors
Significant distortion, small targets, performance impact
Ultra-wide monitors (21:9, 32:9), battle royales
Games like CS2, Valorant, and Rainbow Six Siege benefit from moderate FOV that balances awareness with precise aim. Most pros use 90-103 FOV.
Battle royale games (Apex, Warzone, PUBG) favor higher FOV for better situational awareness to spot enemies in open areas.
Fast-paced arena shooters (Quake, Diabotical) use very high FOV for maximum awareness during rapid movement and vertical gameplay.
Games like Overwatch prioritize team awareness and ability tracking, benefiting from moderate-high FOV.
Use this calculator to find your optimal FOV based on monitor size and viewing distance. This gives you a scientifically sound starting point that minimizes distortion.
Apply the calculated FOV and play for 30-60 minutes. Pay attention to: Can you see enough peripherally? Are targets too small? Does it feel natural? Any discomfort or nausea?
Aggressive players may want +5-10° for better awareness. Precision aimers may prefer -5° for larger targets. Adjust in small increments (3-5 degrees) and test each change.
Fast-paced games benefit from higher FOV. Tactical games with precise aim favor moderate FOV. Some games have locked FOV or perform better at certain ranges.
Once you find a comfortable FOV, stick with it for at least a week to build muscle memory. Constantly changing FOV disrupts your spatial awareness and aim consistency.
