Considering rebranding, What is missing in your promotions?or a new logo? Then definately ask for design based on golden ratio (also called the golden rectangle and golden mean) is a shape with a proportion of 1 to 1.618. More complexly, the math can be described like this as explained by the Interaction Design Foundation: Each number in the Fibonacci sequence is simply the sum of the two numbers before it.
So if you remove the left-hand square from the rectangle above, you’ll be left with another, smaller Golden Rectangle. This could continue infinitely. Similarly, adding a square equal to the length of the longest side of the rectangle gets you increasingly closer to a Golden Rectangle and the Golden Ratio.
Golden ratio has been considered to be used by architects and mathematician to construct one the most famous buildings and interiors.
Basically, everything beautiful in the world uses curves created by the the golden ratio. From galaxies to flowers, everything has a sense of golden ratio to it!
