This ratio is the ideal ratio for designs and has been used at multiple places by a number of designers and architects.
Why is the golden ratio so special?
Now that you know what the Golden Ratio is, you might as well be wondering, why this ratio is so
There is a really interesting answer to it. We are subconsciously used to looking at things that have the golden ratio. YES!! Unbelievable but True. The golden ratio is available abundantly in nature. Right from the spikes of the pine cones, a blooming rosebud,
A number of ancient and great sculptors and artists have used this factor in their structures and paintings for years to make them more pleasing and attractive to the human eye. Paintings like the Da Vinci’s Mona Lisa & The last supper and popular & ancient structures like the Greek Parthenon, The Eiffel Tower & even the great pyramids of Giza follow the Golden ratio.
Shapes using the Golden ratio:
A few shapes can be made using the Golden Ratio, the most popular of which is the Golden Rectangle and the Golden Spiral. Both these shapes are discussed in detail below.
– The Golden Rectangle:
A rectangle, the ratio of whose sides is approximately equal to the Golden Ratio, i.e 1.618 is called a Golden Rectangle. It is the ideal rectangle. The idea of the Golden Rectangle can be seen in the structure of the Greek Parthenon.
To understand this better, let’s play a game. Take a pencil and paper and make a rectangle of 34⨯21 cm. Notice that the ratio of these numbers is approximately equal to 1.618. So this is a Golden Rectangle. Now, divide this rectangle by drawing a segment at 21 cms, thus you have a 21⨯21 cm and a 21⨯13 cm rectangle. Now, if you notice carefully, this new rectangle is also a Golden Rectangle. Again divide this new rectangle at 13 cms, creating a 13⨯13 cms square and a 13⨯8 cms rectangle, which is another Golden rectangle. Keep repeating this process and see how each smaller rectangle is a Golden Rectangle. This is the beauty of the Golden Rectangle.
This is a key feature of Golden rectangle, as you keep dividing you get smaller and smaller golden rectangles.
– The Golden Spiral:
The best example of the omnipresence of the Golden Ratio is the Golden Spiral. RIght from a blooming rosebud to the Nautilus Shell a lot of natural phenomenon show this spiral. It is formed as the ratio of the radii of consecutive spirals in it form the golden ratio. It is not the perfect spiral but is much more attractive than it.
A good example of the Golden Spiral being used in the art is that of the famous painting Mona Lisa.
