2.11 Character size and Spacing
There are two basic elements for character layout for text. One is character size and the other is line spacing.
rem-1: Spacing between characters is not as significant as line spacing or character size.
2.11.1 Character size (CHARACTER SIZE)
There are three measurement systems available for font size.
Didot point (European size) (D)
Pica point (English-American type) (P)
Local Size (ex. 号 in Japan) (L)
Also, in some countries, there are popular range of character size. 9-12 Pica points are usually considered as normal sizes because of their popularity (in US). A review was done to see if there are any specific preferences other than 9-12.
