Facial Thirds
Whether your face divides into three equal horizontal bands — jointly the heaviest metric in the score.

The classical rule of equal thirds
A classical proportion rule holds that the face divides into equal thirds: hairline to brow, brow to the base of the nose, and nose base to the bottom of the chin. Real faces rarely divide perfectly, and where the imbalance falls changes the impression substantially — a long lower third reads very differently from a long upper third even when the numeric deviation is identical.
Scoring the worst third, not the average
MogTracker computes all three proportions and scores the largest single deviation from 0.333 rather than the average. Scoring the average would let a long upper third cancel a short lower third and return a misleadingly good result. The metric reports the same maximum deviation it scores on, so the number you see is the number being judged.
Tied for the heaviest weight in the set
This metric uses linear scoring rather than the Gaussian curve most others use. A 1,700-photo calibration run showed the curve was too punishing here, scoring ordinary faces near zero for modest deviations. Its 12% weight ties canthal tilt for the largest share of the composite. Note that the upper third depends on hairline position, so a receding or unusually low hairline shifts this metric independently of any change in bone structure.
How 123,813 people score on facial thirds
This has the most evenly spread distribution of all sixteen metrics — scores populate every band with no pile-up at either end. Combined with joint-heaviest weight, that makes it the single biggest driver of where you land relative to other people. If you want one number to explain your composite, it is this one, and unlike most of the set it is genuinely separating faces rather than assigning nearly everyone the same result.

How to improve your facial thirds
Ideal faces divide evenly into three equal horizontal thirds: forehead, midface, and lower face.
Recommendations are grouped by how invasive they are. Non-invasive options change how the feature reads to an observer; surgical options change the underlying structure and therefore the measurement itself.
If you scored Excellent
Your facial thirds are near-perfectly balanced. This is your strongest structural feature.
Non-invasive
- Maintain current weight — significant weight changes can shift facial proportions
- Hairstyles that frame the face evenly continue to showcase this balance
If you scored Good
Your facial thirds are well-proportioned with minor imbalance. Easy to optimize.
Non-invasive
- Hairstyle volume adjustment: add height if upper third is slightly short
- Beard length tuning can fine-tune lower third proportion by millimeters
Minimally invasive
- Cheekbone filler to add midface projection if midface is the short zone
If you scored Average
Your facial thirds show moderate imbalance. Correcting this has high impact on your overall score.
Non-invasive
- If upper third is short: voluminous hairstyles add perceived height
- If lower third is long: shorter beard shape compresses it visually
Minimally invasive
- Targeted filler (cheekbone or chin) to rebalance the uneven zone
Surgical
- Genioplasty or hairline lowering surgery for structural correction
If you scored Below average
Your facial thirds are significantly imbalanced — this is the highest-weighted metric. Addressing it will have the largest effect on your Harmony Score.
Non-invasive
- Strategic hairstyle: height for short upper third, width for long face
- Beard shaping is essential — match beard length to balance the lower third
Minimally invasive
- Combination of cheekbone + chin filler for non-surgical rebalancing
Surgical
- Hairline lowering surgery for a short upper third
- Sliding genioplasty for precise chin repositioning
- Le Fort I osteotomy for severe midface imbalance
Common questions about facial thirds
Does my hairline affect this score?
Yes. The upper third is measured from the hairline, so recession lengthens it and lowers the score without anything else having changed.
Why does one bad third tank the whole metric?
The score is based on the largest deviation of the three. Averaging would let a long upper third mask a short lower one and hide a visible imbalance behind a good number.
