Human Beauty

"Beauty is in the phi of the beholder."

It has long been said that beauty is in the eye of the beholder and thought that beauty varies by race, culture or era. The evidence, however, shows that our perception of physical beauty is hard wired into our being and based entirely on how closely one's features reflect phi in their proportions. Take another look at beauty through the eyes of medical science.

A template for human beauty is found in phi and the pentagon

Dr. Stephen Marquardt has studied human beauty for years in his practice of oral and maxillofacial surgery. Dr. Marquardt performed cross-cultural surveys on beauty and found that all groups had the same perceptions of facial beauty. He also analyzed the human face from ancient times to the modern day. Through his research, he discovered that beauty is not only related to phi, but can be defined for both genders and for all races, cultures and eras with the beauty mask which he developed and patented. This mask uses the pentagon and decagon as its foundation, which embody phi in all their dimensions. For more information and other examples, see his site at Marquardt Beauty Analysis.

Even with a perfectly proportioned face though, there are endless variations in coloring and the shapes of each facial feature (eyes, eyebrows, lips, nose, etc.) that give rise to the distinctive appearance of each race and provide for endless variations in beauty that are as unique as each individual.

The human face communicates an incredible array of emotions which are an integral element of one's total beauty. The human face conforms most closely to phi proportions when we smile. You'll be perceived as more beautiful with a warm smile than with a cold-hearted look of anger, arrogance or contempt.

The Human Face

George Clooney The human face abounds with examples of the Golden Section or Divine Proportion. We'll use our building blocks again to understand design in the face:

Fibonacci Building Blocks

"The Golden Ruler" a Fibonacci Measuring Stick by "Evolution of Truth"

The head forms a golden rectangle with the eyes at its midpoint. The mouth and nose are each placed at golden sections of the distance between the eyes and the bottom of the chin. The beauty unfolds as you look further.

Paula ZahnHuman beauty is based on the Divine Proportion

The blue line defines a perfect square of the pupils and outside corners of the mouth. The golden section of these four blue lines defines the nose, the tip of the nose, the inside of the nostrils, the two rises of the upper lip and the inner points of the ear. The blue line also defines the distance from the upper lip to the bottom of the chin.

The yellow line, a golden section of the blue line, defines the width of the nose, the distance between the eyes and eye brows and the distance from the pupils to the tip of the nose.

The green line, a golden section of the yellow line defines the width of the eye, the distance at the pupil from the eye lash to the eye brow and the distance between the nostrils.

The magenta line, a golden section of the green line, defines the distance from the upper lip to the bottom of the nose and several dimensions of the eye.

Click on the photo to the left to see another photo which illustrates the following golden sections in the human face:
  • Center of pupil : Bottom of teeth : Bottom of chin
  • Outer & inner edge of eye: Center of nose
  • Outer edges of lips : Upper ridges of lips
  • Width of center tooth : Width of second tooth
  • Width of eye : Width of iris

Phi defines the dimensions of the human profile

The Divine Proportion in the Facial Profile Even when viewed from the side, the human head illustrates the Divine Proportion.

The first golden section (blue) from the front of the head defines the position of the ear opening. The successive golden sections define the neck (yellow), the back of the eye (green) and the front of the eye and back of the nose and mouth (magenta). The dimensions of the face from top to bottom also exhibit the Divine Proportion, in the positions of the eye brow (blue), nose (yellow) and mouth (green and magenta).

The ear reflects the shape of a Fibonacci spiral.

Even the dimensions of our teeth are based on phi

The front two incisor teeth form a golden rectangle, with a phi ratio in the heighth to the width.

The ratio of the width of the first tooth to the second tooth from the center is also phi.

The ratio of the width of the smile to the third tooth from the center is phi as well.

Phi ( Ø )

Phi for Neo-phi-tes
What is Phi?

Phi ( Ø ), is simply an irrational number like pi (p), but one with many unusual mathematical properties. Phi to the first 15 places is 1.618033988749895. What makes it more unusual is that it can be derived in many ways and shows up in relationships throughout the universe.
Phi Ø can be derived through:

*A numerical series discovered by Leonardo Fibonacci



Phi Ø appears in:

*The proportions of the human body
*The proportions of many other animals
*The solar system
*Art and architecture
*Population growth
*The stock market
*The Bible and in theology

The ratio, or proportion, determined by Phi (1.618...) was known to the Greeks as the "Golden Section" and to Renaissance artists as the "Divine Proportion"

Phi with an upper case "P" is 1.618033987..., while phi with a lower case "p" is 0.6180339887, the reciprocal of Phi and also Phi minus 1.
