Scaling behaviors of critical current density \(J_{c}\) in \(\hbox {MgB}_{2}\) thin films are investigated on different films with thickness of 100 nm, in comparison with 50- and 10-nm films based on a comprehensive scaling formula. Experimental data are reduced and analyzed with the formula over a wide range of magnitudes. In 100- and 50-nm films the single scaling function has been able to fit experimental \(J_{c}\) data up to ten orders of magnitudes with appropriate flux pinning parameters. On the other hand, for the 10-nm film, different \(J_{c}\) dependences were found on temperature and magnetic field, concerning anomalous or granular superconductivity.
