[edit]Book design
Depiction of the proportions in a medieval manuscript. According to Jan Tschichold: "Page proportion 2:3. Margin proportions 1:1:2:3. Text area proportioned in the Golden Section."[37]
Main article: Canons of page construction
According to Jan Tschichold,[38]
There was a time when deviations from the truly beautiful page proportions 2:3, 1:√3, and the Golden Section were rare. Many books produced between 1550 and 1770 show these proportions exactly, to within half a millimeter.
[edit]Finance
The golden ratio and related numbers are used in the financial markets. It is used in trading algorithms, applications, and strategies. Some typical forms include: the Fibonacci fan, the Fibonacci arc, Fibonacci retracement, and the Fibonacci time extension.[39]
[edit]Industrial design
Some sources claim that the golden ratio is commonly used in everyday design, for example in the shapes of postcards, playing cards, posters, wide-screen televisions, photographs, and light switch plates.[40][41][42][43]
