Within this universe, we see a lot of order—order reflecting its Creator. And that order can be seen manifested in the mathematical constants of e, π (pi), or φ (phi). This real number called phi has an interesting characteristic.
When this is called the golden ratio of 1.61803399…
It turns out, this certain ratio has a characteristic that appears often throughout this universe. Furthermore, this ratio—when applied to design—creates a form general pleasing to the human eye. The Greeks (intentionally or not) used this ratio in their architectures, we see this appearing in medieval book designs, and even in the ratio of the human face.
We can also use this same ratio in designing the web. In this modest(*cough*) example above, the red logo at the top right corner has a rectangular shape with the height 1.618 times the length of its width. Similarly, the box at center has a width with the golden ratio to the height. The length of the image box is also a golden ratio to the length of the text box to its right. Finally, the entire website has a general shape that corresponds to the golden ratio.
Some have even used the “golden angle” with the arc divided by the ratio, in design. Golden ratios can also be found in other forms such as the curious Fibonacci sequence.
I won’t go into that in this post as that deserves a post on its own. However, if you look around, I’m sure you will start to see aspects of this interesting mathematical constant appearing around you in industrial, graphic, print, and web design.
