The chin is the strangest feature in the dataset, and understanding why makes the phrase "weak chin" much less frightening than it sounds online.
Across 17,032 AI face analyses run between January and August 2026, the chin is a person's single highest-scoring feature 0.1% of the time. That is the lowest figure of any of the twelve measured features, by a distance. The same feature is a person's single lowest-scoring feature 8.4% of the time. Whatever else the chin does, it does not win.
A feature that only points downward
Comparing how often each feature is someone's best against how often it is their worst sorts the twelve into three kinds. Some features carry people. Some are neutral. A few only ever subtract.
| Feature | Best feature | Worst feature | Mean |
|---|---|---|---|
| Eyebrows | 29.3% | 1.9% | 5.94 |
| Eyes | 20.1% | 0.1% | 5.97 |
| Jawline | 16.0% | 9.1% | 5.59 |
| Skin | 11.8% | 38.0% | 5.30 |
| Lips | 11.4% | 6.2% | 5.65 |
| Cheeks | 1.0% | 6.6% | 5.42 |
| Nose | 0.5% | 9.0% | 5.36 |
| Chin | 0.1% | 8.4% | 5.39 |
The chin sits at the bottom of the best-feature column and near the top of the worst-feature column. The nose behaves similarly, at 0.5% best and 9.0% worst. These are the two features that essentially only cost points.
That asymmetry is the single most useful thing to know if you are worried about your chin. Nobody's face is being carried by their chin. The upside you may be imagining for a stronger one does not exist in this data. What exists is a downside, and it is a real one, but it is one item among twelve rather than a verdict.
How much a weak chin actually costs
The spread is genuinely wide. People scoring 8.0 or above overall average 8.48 on the chin; people scoring under 5.0 average 4.43. That is a gap of 4.05 points, the fifth-widest of the twelve features, behind the jawline at 4.36, bone structure at 4.32, skin at 4.28 and facial harmony at 4.11.
But the chin also correlates with the overall score at 0.96, which is high. In practice that means the chin score tends to travel with everything else rather than moving on its own. A low chin score in a face that otherwise scores well is uncommon; far more often, a low chin score is one reading of the same underlying structure that the bone structure and harmony scores are also reading.
The chin averages 5.39 out of 10, below the overall mean of 5.59, and only 10.6% of people score 7 or above on it. So a middling chin score is the normal case, not a diagnosis. The population it belongs to is very large.
Two things worth putting next to your chin score
The first is how ordinary tied features are. Across everyone, 58.0% of people tie for their worst feature, meaning more than half do not have one clear weak point at all - they have several features sitting at the same low value. If your chin came back as your weakest feature, there is a good chance it is sharing that position rather than standing alone in it.
The second is the size of the whole spread. The average distance between a person's best and worst feature is 1.38 points. That is the width of the thing being discussed. A chin at the bottom of your own face is typically about a point below your top feature, not a chasm, and the overall score is built from all twelve.
Is a weak chin fixable?
The chin is marked improvable "No" in this data, and that assessment is honest rather than defeatist. The chin is part of the mandible. It is bone. No routine, exercise, posture habit or device changes adult bone, and the online claims that they do are not supported by evidence.
What does change is the outline. Facial hair alters the visible silhouette of the lower face substantially, and for many people that is the entire practical lever. Head angle changes it too: a camera held below eye level shortens the apparent chin and thickens the area beneath it, while a straight-on shot at eye level is the honest one. Body composition affects the region under the chin rather than the chin itself, which is a different thing being read in the same part of the photograph.
This guide does not recommend cosmetic surgery. If that is a serious question for you, it is a conversation with a board-certified surgeon about your anatomy and your health, and no score from any app, ours included, is a reason to start it.
Keeping the number in proportion
It is worth being direct about who reads a page like this. People do not look up "weak chin" because they feel good about their face. So two things are worth stating plainly.
First, the research on facial attractiveness does not support the idea that any one structural feature decides how a person is perceived. Rhodes (2006), reviewing the evidence, found that even the strongest structural factors have moderate effects on how faces are rated, not decisive ones. That cuts in the reassuring direction here: a single feature at the bottom of the twelve is not carrying the weight the forums assign it.
Second, this is one model scoring geometry in one photograph. It does not see expression in motion, voice, warmth or how a person actually comes across, and those carry enormous weight in real life. A chin score is a measurement, not a judgement about you.
To see your own number rather than an impression of it, the chin rating tool scores this feature on its own against the 5.39 average and the 10.6% who clear a 7. Because the chin correlates so tightly with everything around it, the more informative version is the full face rating, which returns all twelve features and shows whether the chin is genuinely your weak point or simply tied with several others. The jawline rating covers the neighbouring region, which is scored separately and has far more room to move.
