## About Midface Ratio Calculator (Formula)

The Midface Ratio Calculator is an important tool in the fields of cosmetic surgery, orthodontics, and facial aesthetics. It helps professionals assess facial proportions by comparing the interpupillary distance to the distance from the pupil center to the top of the lip. Understanding midface proportions is crucial for achieving balanced and harmonious facial aesthetics, whether for surgical planning, orthodontic treatment, or aesthetic evaluations. This article will discuss the formula for calculating the midface ratio, guide you on how to use the calculator, and provide practical examples.

### Formula

The formula for calculating the midface ratio is Midface Ratio = Interpupillary Distance / Distance from Pupil Center to Top of the Lip. This ratio provides insights into facial proportions and helps guide aesthetic evaluations.

### How to Use

To effectively use the Midface Ratio Calculator, follow these steps:

- Measure the interpupillary distance (the distance between the centers of the pupils) in millimeters.
- Measure the distance from the pupil center to the top of the lip in millimeters.
- Insert these values into the formula: Midface Ratio = Interpupillary Distance / Distance from Pupil Center to Top of the Lip.
- Calculate the midface ratio to assess facial proportions.

### Example

Suppose the interpupillary distance is 60 mm, and the distance from the pupil center to the top of the lip is 30 mm. Using the formula:

- Interpupillary Distance = 60 mm
- Distance from Pupil Center to Top of the Lip = 30 mm

Calculating the midface ratio: Midface Ratio = 60 mm / 30 mm = 2

Thus, the midface ratio in this example is 2, indicating that the interpupillary distance is twice the distance from the pupil center to the top of the lip.
