Abstract: Using the CHARA Array and NPOI interferometers, we measured the angular diameters of 37 G and K giant stars. The combination of these measurements and Hipparcos parallaxes produce physical radii for the sample. Except for a few outliers, our values match angular diameters estimated using photometric methods to within the associated errors with the advantage that our uncertainties are significantly smaller. We also calculated the effective temperatures for the stars using the newly-measured diameters, and then estimated masses and ages for the stars using our temperatures combined with metallicity measurements from the literature and a stellar model.
