HOW IT IS CALCULATED
Calculate angular field of view
Larger sensors or shorter focal lengths give wider FOV

01Values
022 × atan(sensor ÷ (2 × focal))
03Result
Larger sensors or shorter focal lengths give wider FOV
Field of view depends on the sensor dimension being measured
Horizontal, vertical and diagonal FOV use different sensor dimensions.

In short
What logic does the calculator use?
2 × atan(sensor ÷ (2 × focal))
Example?
Larger sensors or shorter focal lengths give wider FOV
