What is golden ratio

And here is a surprise: when we take any two successive one after the other Fibonacci Numbers, their ratio is very close to the Golden Ratio. In fact, the bigger the pair of Fibonacci Numbers, the closer the approximation. Let us try a few:. We don't have to start with 2 and 3 , here I randomly chose and 16 and got the sequence , 16, , , , , , , , , , , , , I believe the Golden Ratio is the most irrational number.

Here is why No, not witchcraft! The pentagram is more famous as a magical or holy symbol. You can also take this idea and create a golden rectangle. Take a square and multiple one side by 1. If you lay the square over the rectangle, the relationship between the two shapes will give you the Golden Ratio. If you keep applying the Golden Ratio formula to the new rectangle on the far right, you will end up with an image made up of increasingly smaller squares.

Now that the math lesson is over, how can you apply this knowledge to the work you do on a daily basis?

Here are four ways to use the Golden Ratio in design:. The Golden Ratio can help you figure out what size font you should use for headers and body copy on a website, landing page, blog post, or even print campaign. If you multiply 12 by 1. If you want to figure out how big your body text size should be, you could do the opposite.

If your header text is 25px, you can divide it by 1. But, how do you make sure the image is still balanced after you resize it? For example, if you overlay the Golden Spiral on an image, you can make sure that the focal point is in the middle of the spiral. Designer Kazi Mohammed Erfan even challenged himself to create 25 new logos entirely based on the Golden Ratio.

The result? Simple, balanced, and beautiful icons. What do you think the proportions of a golden rectangle are? A golden rectangle uses the golden ratio: 1 short side by 1. Fibonacci sequences are everywhere in your body. Look at yourself in the mirror: two eyes , two ears , two nostrils in one nose , five fingers on an arm with three segments hand, forearm, upper arm.

Fibonacci numbers are even encoded in your DNA. Each DNA molecule is 34 angstroms long and 21 angstroms wide: a golden ratio. Don't look too closely, though! Just like the four-leaf clover, there are plenty of natural sequences that do not correspond to the golden ratio.

A full set of permanent teeth, for instance, is 32—not a Fibonacci number. Your heart has four chambers—not a Fibonacci number.
