The Golden Ratio represents the perfectly symmetrical relationship between two proportions.
Its most famous application is the golden rectangle, which can be split into a perfect square, and a smaller rectangle that has the same aspect ratio as the initial one.
It is claimed that the designs following the golden ratio are the most pleasing layouts to the eye. The golden ratio has earned a tremendous reputation: The Pyramids of Giza, Da Vinci’s Mona Lisa, Twitter and Pepsi logos are all said to be designed using the Golden Ratio.
However, many designers do not follow the Golden Mean and identify it as a myth, arguing that the Golden Ratio is always going to be a little off.
