I wonder how the visual density of Hanzi vs. Pinyin (or English) compares. On the one hand, each hanzi is approximately equivalent to about 4 letters of Pinyin, and Hanzi text uses no spacing (which would otherwise be needed approximately every 2 Hanzi). On the other hand, apparently Hanzi text should be approximately 1.3 times the vertical height of Roman text, according to the article, and Hanzi are square, so significantly wider than a Roman character. From my observations, it seems that Chinese text ends up slightly denser than the equivalent English text, but not overwhelmingly so, but surely there should be an actual comparison somewhere...
