The Parchment Era: Birth of Perfect Proportions

Golden Ratio in Manuscripts

Medieval masters created a proportional system based on the golden
ratio (1:1.618), which is still considered the standard of beauty and
functionality.

Canonical Margin System:

Inner margin: 1 part
Top margin: 1.5 parts
Outer margin: 2 parts
Bottom margin: 3 parts

Reasons for this system:

Functionality:

Text protection from finger wear
Space for reader’s notes
Binding convenience
Preservation during page trimming

Aesthetics:

Visual page balance
Optical perspective compensation
Harmonious spread proportions
Text perception comfort

Page Layout Method:

Division into 9 parts vertically and horizontally
Text block isolation
Margin proportion calculations
Lines and columns marking
