No, he was 5'7" (after converting French feet to modern feet), and that was slightly taller than average for the time. If you don't care about "average height for the time", then you're just being intentionally obtuse. The average height of the time and place is the only thing that matters for defining "short" and "tall". (He was likely shorter than his Imperial Guards, who were chosen on the basis of height, which would have made him look short by comparison when seen in public, much like Arnold Schwarzenegger looks like a little person when he's seen next to Andre the Giant and Wilt Chamberlain.) By the standards of the Dutch, you're probably a short, tiny little person too. But by the standards of modern America, Napoleon was average: the average height of a man in America in 2017 is 5'7" (last time I checked). Standards vary from place to place and time to time. In modern Japan, he'd probably be considered a little tall. In modern Netherlands, most of us are short.
