Theoretical view angle calculator based on pinhole camera model. Helpful to determine field of view (FOV) for particular camera sensor and lens combination.

Chose camera to fill sensor size

Calculated view angles

Horizontal field of view, °
Vertical field of view, °
Diagonal field of view, °

Known limitations:

  • Does not take into account that some lenses can cover image partly
  • Gives inacurate results for fisheye and wide angle (>90°) lenses
