What Are Facial Thirds?
Facial thirds describe vertical balance across the face. Because a hairline is not reliably visible in facemesh, this free test compares the measurable middle third to the lower third.

Why It Matters
Middle-to-lower facial balance can affect whether a face reads as vertically harmonious in front-facing photos. It pairs naturally with jaw, chin, nose, and midface measurements.
How It Is Calculated
The test measures glabella-to-subnasale height and subnasale-to-chin height, then reports the middle-to-lower ratio.
