Abstract: This review examines progress on the Pop I, fundamental‐mode Cepheid distance scale with emphasis on recent developments in geometric and quasi‐geometric techniques for Cepheid distance determination. Specifically I examine the surface brightness method, interferometric pulsation method, and trigonometric measurements. The three techniques are found to be in excellent agreement for distance measures in the Galaxy. The velocity p‐factor is of crucial importance in the first two of these methods. A comparison of recent determinations of the p‐factor for Cepheids demonstrates that observational measures of p and theoretical predictions agree within their uncertainties for Galactic Cepheids.
