Publication typography

The rule of 30 / 18 / 9

In CIWA publications, font sizes are standardized to ensure clarity and balance. Main titles are set
at 30 points, subheadings at 18 points, and body text at 9 points. This hierarchy is guided by the
principles of the golden ratio, creating a visually harmonious layout.

This rule is also applied to text spacing wherein the spacing between different text is measured
using font size as distance e.g. the distance between the Main Title and Heading is a full line 30pt
text and so on.
