Calibrators for optical interferometric observation must have properties (in position, magnitude and color) close to those of the scientific target. As a general rule such object doesn't have direct determination of theirs angular radius. A surface brightness relation should be used to compute, from photometry, theirs angular radius. We have compiled stellar diameter (from interferometric measurement, lunar occultation or eclipsing binaries) and BVRIJHK photometry for a large sample of stars of spectral type O to M and for all the luminosity class. Angular radius versus photometry relation have been established, they are used in JMMC Evolutive Search Calibrator tool to compute angular diameter of calibrators. Same for calibrators for which the luminosity class is unknown, the angular diameter is determined with an accuracy between 5 to 10%.
