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.
Examples
- Example: with Sensor width = 23.6 mm, Sensor height = 15.7 mm, Lens focal length = 35 mm, this calculator returns Crop factor = 1.53 x, Full-frame equivalent = 53.4 mm.
Calculation Guide for Camera Crop Factor Calculator
The Camera Crop Factor Calculator computes Crop factor, Full-frame equivalent directly from Sensor width, Sensor height, Lens focal length. Calculate crop factor from sensor diagonal compared with full frame.
Domain Guidance: Engineering specs should always include appropriate safety tolerances and hardware overhead beyond theoretical calculation baselines.
Validation & Privacy: All calculations execute in real-time within client-side WebAssembly and JavaScript engines. No input values are sent across external network requests.
