Using the visual surface brightness technique, we have determined radii for 63 Cepheids. The resulting P-R relation is in better agreement with the P-R relations determined from theory and the cluster Cepheids than the older Boade-Wesselink solutions. We find no evidence that the long and short period Cepheids have different temperature scales.
