← Camera FOV & Calibration
Camera FOV Calculator
Pick a sensor size (or enter your own), a focal length, and a working distance to get the field of view and the imaged coverage at that distance — useful for picking a lens/camera combo or planning where to mount one.
How to use the FOV Calculator
- 1Choose your camera sensor (or type its size) and the lens focal length.
- 2Set the working distance to your target.
- 3Read the horizontal, vertical and diagonal field of view and the area the camera covers, then copy the results.

Uses the pinhole-camera approximation (angle of view = 2·atan(sensor dimension / (2·focal length)), coverage = distance·sensor dimension / focal length) — ignores lens distortion, so results are most accurate for rectilinear lenses without strong barrel/fisheye distortion.
