What the bone structure score reads
The skeleton under the face, as far as a photograph can show it: cheekbone projection and where it sits, the width of the zygomatic arches relative to the rest of the face, the definition of the orbital rims and brow ridge, and how the whole framework carries from temple to jaw. Jawline, chin and cheeks are scored separately, so bone structure is specifically the underlying architecture rather than any one landmark on it.
Across 17,032 analyses it averages 5.6, just above the overall mean of 5.59, with a standard deviation of 1.16 — one of the widest of the twelve. 16.7% of people score 7 or above. It correlates with the overall rating at 0.96, matched only by facial harmony (0.99), which is closer to a summary of the face than a feature of it.
The highest ceiling of any feature we measure
For each of the twelve features we took the 560 faces rated 8 or above overall and the 4,307 rated under 5, and measured what each group averages. Two numbers are worth pulling out of that table: how high the feature goes in the top group, and how far apart the two groups end up.
| Feature | 8+ faces (ceiling) | Under-5 faces | Gap | Correlation | Changeable? |
|---|---|---|---|---|---|
| Bone structure | 8.9 | 4.58 | 4.32 | 0.96 | No |
| Jawline | 8.89 | 4.53 | 4.36 | 0.92 | Partly |
| Facial harmony | 8.66 | 4.55 | 4.11 | 0.99 | Barely |
| Eyes | 8.62 | 5.04 | 3.58 | 0.95 | Partly |
| Symmetry | 8.54 | 4.74 | 3.81 | 0.95 | Barely |
| Chin | 8.48 | 4.43 | 4.05 | 0.96 | No |
| Skin | 8.33 | 4.05 | 4.28 | 0.87 | Yes |
| Eyebrows | 8.27 | 5.11 | 3.16 | 0.9 | Yes |
| Cheeks | 8.25 | 4.5 | 3.75 | 0.96 | Partly |
| Nose | 8.01 | 4.51 | 3.5 | 0.97 | No |
| Lips | 8 | 4.65 | 3.35 | 0.9 | Partly |
| Forehead | 7.66 | 4.84 | 2.82 | 0.93 | Partly |
Bone structure sits at the top of that first column: 8.9 among faces rated 8+, the highest figure any feature reaches anywhere in the dataset. It is also second on separation with a gap of 4.32 points, behind only the jawline's 4.36 — close enough to call a tie. And it does that while marked "No" in the changeable column.
That combination is the whole point of this page. Bone structure is the most decisive feature on the face that you have no ability to alter. It is the single clearest statement the data makes about how much of a face rating is decided before you get any say in it — and the honest response to it is not despair, it is redirection.
Figures use analyses from January 2026 onward (n=17,032), after the Dec 2025 model recalibration. Earlier analyses used a different scale.
The flattest feature and the most decisive one
Bone structure and the forehead are the two ends of the same table, and reading them together is the fastest way to understand what a feature score is worth. Bone structure reaches 8.9 in the top group and separates high from low scorers by 4.32 points. The forehead reaches only 7.66 — the lowest ceiling of any feature — and separates the same two groups by 2.82, the smallest gap of the twelve, with a spread of just 0.78 across everybody.
So a low bone structure score is real information and a low forehead score mostly is not. Everyone is bunched together on the forehead; nobody is bunched together on bone structure. If you are auditing your own face and deciding what to take seriously, that distinction matters more than any single number.
Why a low forehead score means almost nothingYou cannot change it, so change what moves
Adult facial bone does not remodel. Not with mewing, not with chewing gum or hard mastic, not with facial exercise, not with supplements. Every visible "bone structure transformation" is one of three things: lost body fat exposing structure that was always there, a better camera angle, or surgery. The first is worth doing for other reasons. The second is free. The third is a conversation with a qualified surgeon, not a website.
Of the twelve features, only 2 are marked fully changeable — skin and eyebrows — and they are not consolation prizes:
- Skin separates high and low scorers by 4.28 points. That is within 0.04 of bone structure's 4.32 — the same order of importance, on a feature that responds to a basic routine. Skin is also the most common weakest feature by a distance, dragging 38% of faces down as their lowest score, and the lowest-scoring feature of the twelve at a mean of 5.3. It is the largest pool of recoverable points on the face.
- Eyebrows are someone's best feature 29.3% of the time — the highest rate of any feature — and their worst only 1.9%. They average 5.94, one of the highest means of the twelve, and they are the cheapest thing on this list to change.
- Body fat, which sits between the two. It does not change bone structure but it changes how much of it the camera sees, and it moves the jawline (partly changeable) and cheeks (partly changeable) at the same time.
The arithmetic is not subtle. 8.1% of people score 7 or above overall and 3.3% reach 8. If your bone structure is average, you are not getting into that top band on bone structure — but the points available on skin are almost as large a quantity as the points bone structure is holding back, and unlike bone, they are actually on offer.
Getting an accurate bone structure reading
Bone structure is read through soft tissue, so the photo has to let the structure show without inventing it.
- Directional light, not flat light. Structure is visible because it casts shadow. A ring light straight on erases cheekbone projection; light from slightly above and to one side reveals it. Harsh overhead light exaggerates it — that is the "model lighting" effect, and it is not your face.
- Camera at eye level. Shooting from above narrows the lower face and inflates the mid-face; from below it does the reverse. Neither reads your actual skeleton.
- Neutral expression, mouth closed. Smiling lifts the cheek pad over the zygomatic arch and hides the very landmark being scored.
- Hair back from the temples. Temple width is part of the framework; hair covering it removes half the read.
- No contour makeup for a true reading. Contour exists specifically to fake this feature. It will work on the model too, which tells you it works — but the number will not be yours.
Why your score moves between photos
Bone does not change between two photos taken five minutes apart, but the score can. Lighting direction alone is worth a meaningful swing on this feature, more than on most. Take three photos in different light, and treat the middle of the range as your real number rather than the flattering one.
Frequently asked questions
What is good bone structure?
Measured rather than described: bone structure averages 5.6 out of 10 across 17,032 analyses, so anything above that is above average, and 16.7% of people reach 7 or higher. The distinguishing number is the top end. Faces rated 8 or above overall average 8.9 on bone structure — the highest any feature reaches in the entire dataset. Good bone structure means cheekbone projection, orbital and brow-ridge definition, and the width of the underlying skeleton relative to the soft tissue over it.
Can you improve your bone structure?
No, and the study labels it exactly that: "No". It is one of only 3 features marked unimprovable, alongside chin and nose. Adult facial bone does not remodel in response to exercise, tongue posture, chewing or supplements. What genuinely changes is the soft tissue over the bone — body-fat percentage changes how much of the structure is visible — and that is a real effect, but it reveals bone rather than building it.
Does bone structure matter more than other features?
It is the most decisive feature we measure that is also fixed. Bone structure correlates with the overall rating at 0.96, the tightest of the twelve, and separates faces rated 8+ from faces rated under 5 by 4.32 points — second only to the jawline (4.36), and the top group is close enough to call a near-tie. Compare the forehead, which separates the same two groups by only 2.82.
How is bone structure scored differently from jawline and cheeks?
They are three separate scores. Jawline reads the mandibular line from ear to chin (mean 5.59); cheeks read the mid-face soft tissue and its fullness (mean 5.42); bone structure reads the underlying skeletal framework as a whole — cheekbone projection, orbital rims, brow ridge, zygomatic width — independent of how much tissue is sitting on it. A face can score well on cheeks and poorly on bone structure, or the reverse.
Does losing weight improve bone structure?
It does not change your bone structure, but it changes how much of it is visible, which is what a photo reads. That is the honest version of every "bone structure transformation" before-and-after. Worth knowing where the limit is: faces rated under 5 overall average 4.58 on bone structure and faces rated 8+ average 8.9. Revealing structure moves you within that range; it does not move the skeleton.
What score means I have exceptional bone structure?
Anything at 8 or above. Only 16.7% of people reach 7 on bone structure at all, and 8.9 is what the top overall scorers average — a group that is 3.3% of everyone. Bone structure is somebody's single best feature only 3.2% of the time and their worst only 2.6% of the time, which tells you it rarely stands out in either direction; it usually moves with the rest of the face.
Is the bone structure test free?
Yes. The bone structure score comes with the free rating, alongside eleven other feature scores — symmetry among them — and your percentile. You sign in first — Google or Apple, one tap — and it is free.
