When used in technical analysis, the golden ratio is typically translated into three percentages: 38.2%, 50%, and 61.8%. However, more multiples can be used when needed, such as 23.6%, 161.8%, 423%, and so on. Meanwhile, there are four ways that the Fibonacci
Fibonacci number
In mathematics, the Fibonacci numbers, commonly denoted Fₙ form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1. That is, F₀=0, F₁=1, and Fₙ=Fₙ₋₁+Fₙ₋₂, for n > 1. One has F₂ = 1. In some books, and particularly i…

Why is 1.618 so important?
The Golden Ratio (phi = φ) is often called The Most Beautiful Number In The Universe. The reason φ is so extraordinary is because it can be visualized almost everywhere, starting from geometry to the human body itself! The Renaissance Artists called this “The Divine Proportion” or “The Golden Ratio”.
What is Fibonacci Golden Ratio?
The Golden ratio--1.618--is derived from the Fibonacci sequence, named after its Italian founder, Leonardo Fibonacci. In the sequence, each number is simply the sum of the two preceding numbers (1, 1, 2, 3, 5, 8, 13, and so on).
Is 1.625 a golden ratio?

Is the golden ratio infinite?
The number phi, often known as the golden ratio, is a mathematical concept that people have known about since the time of the ancient Greeks. It is an irrational number like pi and e, meaning that its terms go on forever after the decimal point without repeating.
What is the golden ratio for women's bodies?
1.618The Golden ratio says that the perfect proportion is 1.618, and was calculated by looking at famous womens' bust, waist and hip measurements.

Who has the perfect golden ratio face?
Amber HeardAmber Heard is not very popular right now but she does have the most perfect face in the world, according to a doctor who utilized the Greek Golden Ratio of Beauty to support his claim. This ratio of 'Phi' was discovered by the Greeks and it is used in mathematics, art, design, film, photography and much more.
Why is the golden ratio important?
Images: Golden Ratio (or Rule of Thirds) The composition is important for any image, whether it’s to convey important information or to create an aesthetically pleasing photograph. The Golden Ratio can help create a composition that will draw the eyes to the important elements of the photo.
How to crop images using the Golden Ratio?
Another (and slightly simplified) way to crop images via the Golden Ratio is to use the Rule of Thirds. It is not as precise as the Golden Ratio but it will get you pretty close. For the Rule of Thirds, set up all vertical and horizontal lines to 1:1:1 so that all spaces are equal and even.
What is the ratio of a line divided into two parts?
Putting it as simply as we can (eek!), the Golden Ratio (also known as the Golden Section, Golden Mean, Divine Proportion or Greek letter Phi) exists when a line is divided into two parts and the longer part (a) divided by the smaller part (b) is equal to the sum of (a) + (b) divided by (a), which both equal 1.618.
What is the golden spiral?
The Golden Spiral can be used as a guide to determine the placement of content. Our eye is naturally drawn to the center of the spiral, which is where it will look for details, so focus your design on the center of the spiral and place areas of visual interest within the spiral.
Is the Golden Ratio a subconscious attraction?
The Science Forum. In fact, our brains are seemingly hard-wired to prefer objects and images that use the Golden Ratio. It’s almost a subconscious attraction and even tiny tweaks that make an image truer to the Golden Ratio have a large impact on our brains. The Golden Ratio can be applied to shapes too.
Can the golden ratio be used to create circles?
Just like the Golden Ratio can be harnessed to create squares and rectangles that are in harmonious proportion to each other, it can also be applied to create circles. A perfect circle in each square of the diagram will follow the 1:1.618 ratio with the circle in the adjacent square.
What is the golden ratio?
Many books produced between 1550 and 1770 show these proportions exactly, to within half a millimeter. According to some sources, the golden ratio is used in everyday design, for example in the proportions of playing cards, postcards, posters, light switch plates, and widescreen televisions.
What are the angles of a golden triangle?
The angles in a triangle add up to 180°, so 5α = 180, giving α = 36°. So the angles of the golden triangle are thus 36°-72°-72°. The angles of the remaining obtuse isosceles triangle AXC (sometimes called the golden gnomon) are 36°-36°-108°. Suppose XB has length 1, and we call BC length φ.
What is the ratio of a triangle?
If the side lengths of a triangle form a geometric progression and are in the ratio 1 : r : r2, where r is the common ratio, then r must lie in the range φ −1 < r < φ, which is a consequence of the triangle inequality (the sum of any two sides of a triangle must be strictly bigger than the length of the third side). If r = φ then the shorter two sides are 1 and φ but their sum is φ2, thus r < φ. A similar calculation shows that r > φ −1. A triangle whose sides are in the ratio 1 : √φ : φ is a right triangle (because 1 + φ = φ2) known as a Kepler triangle.
What is the difference between a green and red spiral?
Approximate and true golden spirals. The green spiral is made from quarter-circles tangent to the interior of each square, while the red spiral is a Golden Spiral, a special type of logarithmic spiral. Overlapping portions appear yellow. The length of the side of one square divided by that of the next smaller square is the golden ratio.
Is the golden triangle an ABC?
The golden triangle can be characterized as an isosceles triangle ABC with the property that bisecting the angle C produces a new triangle CXB which is a similar triangle to the original.
What is the golden ratio?
The golden ratio describes predictable patterns on everything from atoms to huge stars in the sky. The ratio is derived from something called the Fibonacci sequence, named after its Italian founder, Leonardo Fibonacci. Nature uses this ratio to maintain balance, and the financial markets seem to as well. The Fibonacci sequence can be applied ...
How to find the high and low of a Fibonacci chart?
Finding the high and low of a chart is the first step to composing Fibonacci arcs. Then, with a compass-like movement, three curved lines are drawn at 38.2%, 50%, and 61.8% from the desired point. These lines anticipate the support and resistance levels, as well as trading ranges.

Applications and observations
The Swiss architect Le Corbusier, famous for his contributions to the modern international style, centered his design philosophy on systems of harmony and proportion. Le Corbusier's faith in the mathematical order of the universe was closely bound to the golden ratio and the Fibonacci series, which he described as "rhythms apparent to the eye and clear in their relations with one another. A…
Disputed observations
Examples of disputed observations of the golden ratio include the following:
• Some specific proportions in the bodies of many animals (including humans) and parts of the shells of mollusks are often claimed to be in the golden ratio. There is a large variation in the real measures of these elements in specific individuals, however, and the proportion in question is often significantly differ…
