The Golden Ratio, also known as Divine Proportion and Golden Section and represented by the Greek letter “phi”, is a number (1.618) that occurs in nature that can be seen even in architecture. Golden ratio in the face is abundant.
The whole head forms a golden rectangle with the eyes in the middle, one end at the top of the head and the bottom of the chin as the other end. Forming a line from the top of the head to the tip of the nose with the center of the brow intersecting the line.
Now measure the distance from the tip of the nose to the midpoint of the brow and label it as b. From the midpoint of the brow to the top of the head and label is a. Now divide a with b and you will get the golden ratio, or close enough for some individuals with less symmetry.
Taking the same line, add a and b and divide by a will also give you the divine proportion. This just two of the many naturally occurring phenomenon just on the face alone. Facial symmetry, however, does not connect to beauty.
