The golden ratio is the ideal ratio because it is consistent throughout many aspects in nature - proportions of the human body, the crests and troughs of a heartbeat, the stripes on a tiger's head, et cetera. The value of the Golden Ratio is 0.5*[1 + sqrt(5)] = 1.61803 (to 5 dp)
The average human body height to arm span ratio is approximately one to one. The arm to body ratio in a human is two to one.
the ratio of the mean diameter of the body of a rocket or missile to its length
The golden ratio is also known as 'phi' (a Greek letter written like an 'o' with a vertical line through it. It is an irrational number, but not a transcendental number like e and pi. You can find its value on a calculator by entering (sqrt5 + 1)/2 = 1.6180339887499..... If you break a stick into two unequal parts so that the ratio of the large part to the small part is the same as the ratio of the original stick to the large piece, then that ratio is the golden ratio. The golden ratio was known to Greek mathematicians as long as 2400 years ago. Luca Pacioli wrote about in 1509, sparking modern fascination . The golden ratio is said to be used in the proportions of Greek temples, and to be found in the ratio of various parts of an ideal human body. It is found in many places in nature, such as the pattern of the seeds in a sunflower, and the shape of a snail shell. As far as the pyramids go, many things have been said about the dimensions, proportions and orientation of the Egyptian pyramids, but my view is that this may be our imagination as much as it was actually the method of the builders of the pyramids. This is not to deny that the pyramids are an amazing feat of engineering. By the way, the first pyramids were built about 4600 years ago, 2200 years before the writings of the Greek mathematicians.
The "golden ratio" is simply a number with certain properties. Claims that this number appears all over the place are, to a great extent, exaggerated - no "freak coincidence".

The Greek letter Phi is used to represent the Golden ratio. Some scientists believe that the Golden ratio plays a part in the perception of human beauty, so if one is considering cosmetic surgery, one may want to take the Golden ratio into account.
The golden ratio is 1:1.1618...... This is used in art when making the proportion of the body and the legs. Normally the legs would be 1.1618.. and the top will be the 1. This is counted as the most beautiful proportion
A ratio, by definition, compares two quantities. You might ask what is the ratio of blood to lymph, or what is the ratio of blood to total body weight, or any number of other comparisons. But if you just as what is the ratio of blood, that is a meaningless question.
The average human body height to arm span ratio is approximately one to one. The arm to body ratio in a human is two to one.
The ant has a brain to body mass ratio of 1:7.
the ratio of the mean diameter of the body of a rocket or missile to its length
The ratio is 1: the motion is symmetric.
The Golden Ratio is a mathematical relationship that exists in art, shapes, nature and patterns. This ratio is thought to be aesthetically pleasing and beneficial to the objects that posess them.The Golden Ratio denoted by the Greek letter phi, usually lower case (φ) states that the division of a line segment into two creates a ratio of the shorter part to the longer equal to that of the longer to the whole. It works out to about 1.61803 and is derived from the Fibonacci sequence.For example:The ratio of the short and long sides of a rectangle should be 1.618 (rounded) to be "right".This ratio is used in doors, windows, pictures, books and many other commonly seen rectangular objects.The seeds in a sunflower are 53 to the right and 33 to the left diagonal creating a 1.6 proportionthe swivel of a snail's shellthe length of our body parts in proportion to the whole anatomical bodyacorn seedsThe Golden ratio is also known as the:golden sectiongolden meanextreme and mean ratiomedial sectiondivine proportiondivine sectiongolden proportiongolden cutgolden number
The highest brain to body ratio among large animals is that of the horse, with a ratio of 1.6. Not far behind is the elephant at 1.56, then the lion at 1.55.
