Midface Ratio Calculator: Measure Facial Proportions

The midface ratio measures the middle part of your face to check its balance. It compares distances like between your eyes and from your pupil to your lip. An ideal ratio is about 0.9 to 1.1. Our Midface Ratio Calculator lets you enter measurements to find your ratio. It’s an easy tool to understand your facial proportions and symmetry.

How to Calculate Midface Ratio

The midface ratio assesses the proportions of the middle third of your face, a key aspect of facial aesthetics. It uses the midface ratio formula to compare the interpupillary distance (IPD) to the distance from the pupil to the top of the upper lip. Here’s how to measure and calculate it:

How to Measure Midface Ratio

  1. Measure Interpupillary Distance (IPD):
    Use a ruler or calipers to measure the distance between the centers of your pupils in millimeters (mm). Look straight ahead for accuracy, ideally with assistance or a mirror.
  2. Measure Pupil to Top of Lip Distance:
    Measure the distance from the center of one pupil to the top of your upper lip in millimeters (mm). Ensure the measurement is straight.
  3. Apply the Midface Ratio Formula:
    Divide the IPD by the pupil-to-lip distance:
    Midface Ratio = IPD ÷ Pupil-to-Lip Distance

Illustrative Example Table

MeasurementValue (mm)Notes
Interpupillary Distance (IPD)65 mmDistance between pupil centers
Pupil to Top of Lip Distance60 mmFrom pupil center to top of upper lip
Midface Ratio1.08Calculated as 65 ÷ 60 = 1.08

Example Calculation:

Using the values above, the midface ratio is 65 ÷ 60 = 1.08.

Ideal Midface Ratio

The ideal midface ratio is around 1.0, suggesting balanced proportions. Some sources, like Reddit discussions, indicate 0.8–0.9 can also be attractive, depending on individual features and cultural preferences.

  • Ratio ~1.0: Balanced midface.
  • Ratio < 1.0: Shorter midface.
  • Ratio > 1.0: Longer midface.

Factors to Consider

  • Subjectivity: Beauty standards vary across cultures and individuals.
  • Other Ratios: The midface ratio is one factor; others, like the facial width-to-height ratio (FWHR), also matter.
  • Individual Variation: Natural differences in facial proportions are normal.

Using the midface ratio formula and the example table, you can calculate your midface ratio to evaluate facial harmony.
