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

  1. Enter Focal length (mm) and Sensor width (mm).
  2. Read Horizontal FOV, Vertical FOV, and approximate Diagonal.
