Golden Ratio of Proportionality

This resource is summarised for our purposes here and pertains to Line length, Line height and Font Size:

• The Golden Ratio is approximately = 1.618
• Line height increases with increasing font size, and increasing line length.
  • Landscape view has long line lengths
  • Portrait view has short line lengths
• The screen orientation should be sensed to determine optimal line width: use media queries.
• Font style will have implications on perceived line widths, as stunted fonts versus tall fonts produce a different overhead whitespace.
