How it works
Calculate horizontal and vertical field of view from focal length and sensor width.
Who it's for: Videographers and photographers choosing lenses for a desired framing.
Horizontal FOV = 2·arctan(sensorWidth / (2·focalLength)).
Vertical FOV assumes 3:2 aspect ratio.
Default sensor width 36 mm = full-frame.
How to use
- Enter Focal length (mm) and Sensor width (mm).
- Read Horizontal FOV, Vertical FOV, and approximate Diagonal.
