What is the average font size for the main body of text?
The average font size for the main body of text is 11- or 12-point font. It depends on the particular font and your preference whether 11 or 12 would be more appropriate. Keep in mind that various fonts can look very different at the same point size depending on the style. We generally advise against printing as small as a 10-point font for the main body, but it could be acceptable for some books.
