Camera Field of View Calculator

Find a lens's angle of view.

Calculated Output

Horizontal field of view (deg) 39.598

Formula: FOV = 2 * atan(sensor / (2 * focal))

Step-by-Step Breakdown

1. Values used:

2. Sensor width = 36

3. Focal length = 50

5. Horizontal field of view = 39.598deg

Did this calculator solve your problem today?

The math behind it

FOV = 2 x arctan(sensor width / (2 x focal length)). Longer lenses see a narrower angle.

Full-frame 36 mm sensor with a 50 mm lens gives about 39.6 degrees.

Why does sensor size matter?

A larger sensor captures a wider view at the same focal length.
