Clara Bow, Loretta Young, and Norma Shearer. Loretta Young's height is given as 5'3.5", same as Clara Bow.
About the same height was given for a number of screen stars. The coroner gave 5'3" as Thelma Todd's height, which is close to the same height. Although I don't think that Clara Bow and Loretta Young were taller than Thelma Todd. It looks like someone gave the wrong figures.
