How to Calculate the Golden Ratio

Remember back in 2019 when the internet lost its mind when Bella Hadid was named the prettiest woman in the world? We have learned over time the most gorgeous Hollywood celebrities have a very symmetrical faces when analyzing their beauty with the “Golden Ratio.” What exactly is the Golden Ratio of Beauty? The following article will provide an in-depth review of the golden ratio and how you can use it in your medical practice for improving symmetrical results.

What is the Golden Ratio?

The golden ratio, often denoted by the Greek letter phi (φ), is a mathematical ratio that is approximately 1.618033988749895. It occurs when a line is divided into two parts such that the longer part divided by the shorter part is equal to the whole length divided by the longer part. Mathematically, if $a$ and $b$ are lengths with $a>b$, then the golden ratio is expressed as:

a+ba=ab=ϕaa+b​=ba​=ϕ

This ratio has unique properties and appears in various areas of mathematics, art, architecture, and nature. It is often associated with aesthetically pleasing proportions and can be found in the proportions of the Parthenon, the pyramids of Egypt, and in the spirals of shells and galaxies.

In terms of an equation, the golden ratio satisfies the quadratic equation:

x2−x−1=0x2−x−1=0

The positive solution to this equation is:

ϕ=1+52≈1.618033988749895ϕ=21+5​​≈1.618033988749895

How can you measure the golden ratio in medical esthetics?

In medical aesthetics, the golden ratio is often used as a guideline to achieve harmonious and balanced proportions in facial features and body structures. Here’s how the golden ratio can be measured and applied in medical aesthetics:

• Facial Proportions

  • Vertical Proportions
    • Forehead to Chin: The face can be divided into three equal vertical sections using the golden ratio:
    • From the hairline to the top of the eyebrows.
    • From the top of the eyebrows to the bottom of the nose.
    • From the bottom of the nose to the bottom of the chin.
  • Horizontal Proportions
    • Width of the Face: The width of the face at the cheekbones should be approximately 1.618 times the width at the jawline or the width at the temples.

• Symmetry and Balance

  • Eye Position: The distance between the eyes should be about the width of one eye.
  • Eye to Mouth Distance: The distance from the eyes to the mouth should be about 1.618 times the distance from the chin to the mouth.

• Lip Proportions

  • Upper to Lower Lip Ratio: The height of the upper lip compared to the lower lip should be in the golden ratio, approximately 1:1.618.
