The golden ratio isn’t exact when it comes to the Fibonnacci sequence-the difference between two numbers on the sequence isn’t always exactly equal to the golden ratio, but it’s pretty close. From the Fibonacci sequence, the Greeks developed the golden ratio to better express the difference between any two numbers in succession within the sequence. Starting with 0 and 1, add the last number of the sequence to the number that came before it to create the next number in the sequence. The Fibonacci sequence is easy to remember. It can also be found in famous works of art and architecture and even in our own faces. The ratio itself is derived from the Fibonacci sequence, a naturally occurring sequence of numbers that can be found practically everywhere in nature, from the number of leaves on a tree to the spiral shape of a seashell. Of course, the mathematical equation at work here is much more complicated than that. The golden ratio is probably best understood as the proportions 1:1.618. The golden ratio is a little more complicated, so we recommend you first read our guide to the rule of thirds if math isn’t your forte. Much like the rule of thirds, this mathematical concept can be applied to your graphic designs to make them more visually appealing to the viewer. They expressed this mathematical phenomenon with the Greek letter phi, but today, we call it the golden ratio-also known as the divine proportion, the golden mean, and the golden section. The Ancient Greeks were one of the first to discover a way to harness the beautiful asymmetry found in plants, animals, insects and other natural structures. Want to be on the same creative level as Leonardo Da Vinci, Salvador Dali and the designers of the Parthenon? They all have one simple concept in common.
