1. What is Midface Ratio?

Midface Ratio is a facial measurement that compares the length of the midface to the width of the face. It is used in anthropometry and facial analysis to assess facial proportions and symmetry.

2. How Does the Calculator Work?

The calculator uses the Midface Ratio formula:

Where:

• Midface Length — Vertical distance between specific facial landmarks (mm)
• Face Width — Horizontal distance between the widest points of the face (mm)

Explanation: The ratio provides a standardized measurement of midface proportion relative to overall facial width.

3. Importance of Midface Ratio

Details: Midface ratio is important in facial analysis, orthodontics, and craniofacial surgery. It helps assess facial harmony, diagnose craniofacial abnormalities, and plan surgical interventions.

4. Using the Calculator

Tips: Enter midface length and face width in millimeters. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What are typical midface ratio values?
A: Normal midface ratio values typically range between 0.8-1.2, though this can vary based on ethnicity, age, and individual facial characteristics.

Q2: How is midface length measured?
A: Midface length is typically measured as the vertical distance from the glabella (between eyebrows) to the subnasale (base of the nose).

Q3: How is face width measured?
A: Face width is typically measured as the horizontal distance between the zygomatic arches (cheekbones) at their widest point.

Q4: What does a high midface ratio indicate?
A: A high ratio may indicate a relatively long midface compared to facial width, which could suggest certain craniofacial conditions or specific facial types.

Q5: Can this ratio be used for aesthetic assessment?
A: Yes, midface ratio is one of several measurements used in facial aesthetic analysis to assess facial balance and proportions for cosmetic and reconstructive purposes.
