## Angle of View Formula

The following formula is used to calculate the angle of view of a camera.

AOV = 2arctan (d/2f)

- Where AOV is the angle of view
- d is the chosen dimension (often film or sensor size)
- f is the effective focal length.

To calculate the angle of view, divide the sensor size by 2 times the effective focal length, take the inverse tangent of this result, then multiply by 2.

## Angle of View Definition

An angle of view, or AOV for short, is defined as the angular extent of a scene that can be captured by a camera.

## Angle of View Example

How to calculate an angle of view?

**First, determine the film size.**Calculate or measure the chosen dimension, usually the film size.

**Next, determine the focal length.**Calculate the effective focal length.

**Finally, calculate the angle of view.**Using the equation above, calculate the AOV.

## FAQ

**What is an angle of view?**

An angle of view is the total extent of a scene that a camera can see. This term is also sometimes referred to as field of view.
