Chapter 7: Typography

Various sizes on the G scale relate to one another in terms of being either half or double

the size of other sizes in the same scale. e following sizes on the G scale relate to one

another in terms of being pure or close multiples of one another:

1G and 4G•

• G (Initial G), 2G, 5G, and 7G

3G, 6G, and 8G•

Table 7-3 provides these same G units together, as used in Japan and China, along with the

equivalent sizes in points so that it is clear how they are related. For the values as used in

China, the fractional or “small” values are provided in parentheses.

Needless to say, the G is a typographic unit of measurement whose scale limits the maxi-

mum size of a character to 42 points. It is also no longer used.

Some page-layout systems also use the notion of “character” as a typographic unit. Found-

er FIT and Canon EDICOLOR, for example, allow the user to specify dimensions in terms

of number of characters, for both the horizontal ...
