Harmony
Proportion — how the parts of your face relate to each other. The only pillar that is pure geometry, and the largest one.
Harmony asks one question in forty-four different ways: do the parts of this face agree with each other?
Not whether any single feature is good. A nose is not too big on its own — it is too big relative to a mouth, a midface, a facial height. Harmony is the pillar that measures those relationships.

What it actually measures
| Family | Examples |
|---|---|
Thirds and proportion | Upper, middle and lower third · midface ratio · lower-third split |
Widths | Bitemporal, bizygomatic and bigonial width · eye separation · mouth-to-nose width |
Eyes | Canthal tilt · eye aspect ratio · upper-eyelid exposure · orbital vector |
Nose | Nasal projection · nasofrontal, nasofacial and nasolabial angles · tip rotation |
Jaw and chin | Gonial angle · mandibular plane · ramus-to-mandible · chin projection against the Frankfort plane |
Profile lines | E-line, S-line and H-line lip positions · total facial convexity · Z angle |
The side photo carries 23 of the 44, which is why a scan with no usable side profile loses so much: it is not a rounding error, it is more than half the pillar's evidence about your projection, your jaw angle and your chin.
How a measurement becomes points
Each measurement is compared against a range, and lands in a band. Closer to the ideal range earns more of that measurement's available points; the bands are graded rather than pass/fail, so a value just outside is not treated like one wildly outside.
Not every measurement is worth the same. The ones that carry more weight are the ones that change how a face reads most — and they are not always the ones people obsess over.
What moves it
Honestly: mostly structure. Harmony is the most skeletal of the five pillars, and a gonial angle is not something a routine changes.
That does not make it useless to know. It makes it the pillar that tells you which structural things actually matter on your face, in what order — which is exactly what the Protocol ranks. And a handful of the 44 do move: anything involving soft tissue around the eyes and mouth, anything the fat pad sits on, and everything on the list that was never really about your face at all — a tilted head, a covered tragus, a landmark in the wrong place.
Before you conclude that a Harmony measurement is telling you something about your bones, check that it is telling you something about your photo.
