What is an FOV Calculator?
An FOV (Field of View) Calculator determines optimal gaming and simulation settings based on monitor size, distance, and viewing angles.
How to use
Enter your monitor size, aspect ratio, and viewing distance. The calculator recommends the ideal FOV setting for your setup.
Frequently Asked Questions
What is a Field of View (FOV) Calculator used for?
This calculator determines the angular extent of the scene that is visible through a camera lens. It helps photographers and cinematographers understand how much of the world will be captured based on the lens focal length and the camera sensor size.
What inputs do I need to calculate the FOV?
You typically need two main inputs: the Focal Length of your lens (in millimeters) and the dimensions of your camera's Sensor (Width and Height in millimeters).
How does sensor size affect the Field of View?
A larger sensor captures a wider portion of the image projected by the lens. If you keep the same focal length but switch to a smaller sensor, the field of view becomes narrower (often described as a 'crop factor').
What is the difference between Horizontal, Vertical, and Diagonal FOV?
Horizontal FOV measures the angle across the width of the frame, Vertical FOV measures across the height, and Diagonal FOV measures across the corner-to-corner. The aspect ratio of your sensor dictates the relationship between these values.
Does this calculator account for lens distortion?
No, this calculator assumes a standard rectilinear lens where straight lines appear straight. Fisheye or wide-angle lenses with significant barrel distortion may have a different effective real-world field of view than the calculated geometric result.
Why do I get different results for the same lens on different cameras?
This is due to the 'Crop Factor'. If Camera A has a Full Frame sensor (36mm wide) and Camera B has an APS-C sensor (23.5mm wide), the same 50mm lens will appear zoomed in (narrower FOV) on Camera B.
