Hmm...I just checked MXy's 1980s and 1990s Who's Who pages. The original Who's Who has the Earth-Two Mxyztplk as 2'11" and the Earth-One Mxyzptlk as 3'9". Update '88 and the 1990-1992 loose-leaf edition have the Post-Crisis New Earth Mxyzptlk as Variable.

If the 4'6" stat is legit it comes from a Secret Files entry, a DC Enyclopedia-type entry or an actual story. Meanwhile, I'm changing/removing that stat until it is properly cited.
