This field of view (FOV) calculator will help you determine the viewing angle for your camera setup based on sensor size and lens focal length.
Field of View Calculator
This calculator helps you to find the horizontal field of view (FOV) given the vertical FOV, screen width, and height. Follow the steps below to calculate the horizontal FOV.
How to Use the Calculator
- Enter the vertical field of view (in degrees) in the first input.
- Input your screen width in pixels in the second input.
- Provide your screen height in pixels in the third input.
- Click the “Calculate” button to get your result.
How it Calculates the Results
The calculator converts the vertical FOV from degrees to radians, then calculates the horizontal FOV based on the aspect ratio derived from your screen’s width and height.
Limitations
This calculator assumes a simple pinhole camera model and does not account for lens distortion or other advanced effects that may be present in actual camera systems or specific software applications.
