Interesting. I checked Wikipedia again, and apparently the issue of Napoleon's height is in dispute.

http://en.wikipedia.org/wiki/Napoleon_Bonaparte#Napoleon.27s...

"Many historians have recently argued that, contrary to popular belief, Napoleon was not short as often depicted in popular culture. Although historians disagree on Napoleon's precise height, it has been suggested that he was actually slightly taller than the average early 19th-century Frenchman.[27] Some historians claim the French emperor's height was recorded as 5 ft. 2 in French units, corresponding to 1.68 meters or 5 ft. 6 in Imperial units."

I remember reading that the officials he was surrounded with were mostly taller than he was, so he looked short relative to tall people.
