Issue with that question is that Europe itself has a much larger variation in height in a small geographical area than it seems most of the world does, but all of those fall under "white." A solid 2-3 inch difference from just a few hundred miles.

I'd wager that 5'9 to 5'11 just depending on area is a safe bet for anyone.

Either way, most white guys are taller by a head than most white girls, and any non-Scandanavian girl period, which is what the majority of the height care matters. And women are so bad at judging numbers you can just say 6'2 at 5'9 and they believe it, which is probably where the overestimation gets born.
