# Calculate FOV and imaging distance

Using our online calculators you can determine which Zivid camera best fits your application in terms of the FOV and distance of imaging. To get a visual representation, you can download CAD files of Zivid cameras with FOV from https://www.zivid.com/downloads. If you are looking for the FOV and working distance information in a written form, please check out our datasheet, which is on the same webpage.

Zivid defines the **working distance** as "the distance from the camera lens to the object of interest". For a 3D object, there will be a large number of these distances. This is because it only applies to a single z-value, and all points in the corresponding x-y plane.

**FOV calculator** - outputs the size of the FOV (width and height) and spatial resolution for a given Zivid camera model and the imaging working distance.

**Distance calculator** - outputs the distance of imaging that a given Zivid camera requires to achieve a given size of the FOV (width and height).

For cases where two camera models are both in the optimal working distance for your application, chose the one with lower point precision (it is lower because the working distance is closer to the focus point).
