Samuel Reshevsky was another very short player (it says 5' 2" in my notes, though I haven't recorded the source for that).
Max Euwe was 6' 2" (he looks taller than that in some pictures).
He looks taller than that because he played Sammy a lot.
There's a picture in the 1948 WC match book with all five candidates. Botwinnik looks like average length, but Euwe, Smyslov and Keres all tower over him - Keres looks about an inch shorter than Smyslov and Euwe is somewhere in between. Sammy in the foreground comes up to Keres' shoulder. Vidmar, the chief arbiter, is slightly shorter than Botwinnik, but makes up for it with corpulence.
Edit: and from the 1935 match book, Alekhine looks about the same size as Botwinnik (at least, assuming Max didn't change size in between), while Salo Flohr must've been even shorter than Reshevsky.
