# Golden ratio

Golden ratio is often used for make the most aesthetically appeasing rectangles and spirals for design.

‘Golden ratio is a special number approximately equal to 1.618′(mathsisfun,2017).

‘The golden ratio—which is 1:1.618—occurs on its own in the natural world. It appears everywhere from nautilus shells to the human face. But people didn’t start harnessing its power until a mathematician named Fibonacci created the sequence of numbers that describes the ratio.'(Ifhan Ahmad,2016)

The Golden ratio was created from the fibonacci sequence. The fibonacci sequence is a sequence of numbers in which the previous two numbers are added together to get the next number. (0 1 1 2 3 5 8 13 21…).

All golden ratio shapes, if continued long enough, will create a spiral.

The golden ratio is used in everything from nature, architecture, art to design. Being used in most, if not all, famous logos and historic artwork. This can also be found in design when laying out typography with the positioning and the sizing of the fonts.

I will be using the golden ratio often throughout my design, I will measure out the correct sizing of the book’s size and shape using the ratio in order to achieve the best shape to increase the appeal of the book and I will use the ratio to get the perfect positioning and size for the typography and illustrations. Trying to use every way possible to make the book special, however I will try not to go over the top with using too much creating a negative effect.

Making a rectangle from the golden ratio

Make a square.

Halve the square

Draw a diagonal line through one rectangle.

Rotate the line to extend from the base of the square.

Matching the top of the square make a new rectangle which reaches to the end of the new line.

Now you should have a rectangle made from using the golden ratio.
