We report measurements of the angular scale of cosmic homogeneity ($\theta_{h}$) using the recently released luminous red galaxy sample of the sixteenth data release of the Sloan Digital Sky Survey (SDSS-IV LRG DR16). This consists on a model-independent method, as we only use the celestial coordinates of these objects to carry out such an analysis. The observational data is divided in thin redshift bins, namely $0.67<z<0.68$, $0.70<z<0.71$, and $0.73<z<0.74$, in order to avoid projection biases, and we estimate our uncertainties through a bootstrap method and a suite of mock catalogues. We find that the LRGs exhibit an angular scale of homogeneity which is consistent with the predictions of the standard cosmology.
