Enter the ratings for symmetry of facial features, evenness of skin tone, normality of facial features, measure of facial proportions, and clarity of skin into the calculator to determine the Facial Attractiveness Index.

Facial Attractiveness Index Formula

The following formula is used to calculate the Facial Attractiveness Index.

FAI = (S + E + N + M + C) / 5

Variables:

• FAI is the Facial Attractiveness Index
• S is the symmetry of facial features (rated 1-10)
• E is the evenness of skin tone (rated 1-10)
• N is the normality of facial features (rated 1-10)
• M is the measure of facial proportions (rated 1-10)
• C is the clarity of skin (rated 1-10)

To calculate the Facial Attractiveness Index, add the ratings for symmetry of facial features, evenness of skin tone, normality of facial features, measure of facial proportions, and clarity of skin. Then, divide the total by 5 to get the average score.

What is a Facial Attractiveness Index?

A Facial Attractiveness Index is a numerical value or score that is used to quantify the attractiveness of a person’s face. This index is often calculated using various factors such as symmetry, proportions, and features that align with societal or cultural standards of beauty. It is often used in scientific research, cosmetic surgery, and in some cases, artificial intelligence and machine learning to train algorithms in facial recognition.

How to Calculate Facial Attractiveness Index?

The following steps outline how to calculate the Facial Attractiveness Index (FAI).

1. First, determine the symmetry of facial features (S) rating (rated 1-10).
2. Next, determine the evenness of skin tone (E) rating (rated 1-10).
3. Next, determine the normality of facial features (N) rating (rated 1-10).
4. Next, determine the measure of facial proportions (M) rating (rated 1-10).
5. Next, determine the clarity of skin (C) rating (rated 1-10).
6. Finally, calculate the Facial Attractiveness Index (FAI) using the formula: FAI = (S + E + N + M + C) / 5.
7. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Symmetry of facial features (S) rating = 8

Evenness of skin tone (E) rating = 7

Normality of facial features (N) rating = 9

Measure of facial proportions (M) rating = 6

Clarity of skin (C) rating = 8
