Possible formula for thesis text with 7 heading levels:
Body Copy = 12pt all type sizes are based off this measure (in increments of 2 points)
Line Spacing 24pt = 1.5 spaced (32pt would be double-spaced) all spaces are based on this measure
Body copy set with no indents, instead uses 1/2 line space as space between (para space) in this case = 12pt*
Headings all use the same typeface (which may differ from body text typeface):
Section Head = 18pt (8 pts larger than body copy) usually set all caps, on a page by itself
Chapter Head = 16pt (4 pts larger than body copy) Bold, looks best with 3 to 5 para spaces below (so 36pt/60pt)
A Head (14pt) = set bold, 2 para spaces above, one para space below (24pt above/12 below)**
B Head (14pt) = set bold italic, 2 para spaces above, one para space below (24pt above/12 below)
C Head (12pt) = Set bold, 1.5 line space above, one para space below (18pt above/12pt below)
D Head (12pt) = Set regular, 1 para space above, 1 para below (12pt above and below)
E Head (12pt) = Set italic, 1 para space above, 1 para below (12pt above and below)
Footnotes and Page Numbers set in body text @ 8–10pt
* Paragraphs above headings should be set with no space below.
**When one heading is above another, delete the space below the top heading.
