Calculateur de Camera Crop Factor
Calculate crop factor from sensor diagonal compared with full frame.
Formula and method
This calculator computes Crop factor, Full-frame equivalent directly in your browser without sending data to an external server.
Mathematical formula
- Crop factor:
43.266615305567875 ÷ √(sensorWidth × sensorWidth + sensorHeight × sensorHeight) - Full-frame equivalent:
lens × 43.266615305567875 ÷ √(sensorWidth × sensorWidth + sensorHeight × sensorHeight)
Variables and parameters
- Sensor width (sensorWidth): default value 23.6 mm.
- Sensor height (sensorHeight): default value 15.7 mm.
- Lens focal length (lens): default value 35 mm.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
