Several direct and indirect methods for the determination of stellar apparent diameters have been developed in the past; they are summarized in Table 1 by Fracassini, et al. (1981) with a code number and references. So far, no detailed comparison of the methods has been carried out, the main difficulty being the extremely small number of common stars. Nevertheless, from the stars listed in CADARS (Fracassini, et al. 1981), we have obtained some correlations in order to test the reliability of some methods and to define the regions of the HR diagram where they can be applied.
