Across 17,032 AI face analyses, the forehead averages 5.39 out of 10, a little below the overall average of 5.59. That number on its own is not interesting. What is interesting is how little the forehead score moves, in either direction, for anybody.
The forehead has the most compressed distribution of the twelve measured features. It has the smallest spread, the lowest ceiling of any feature on the face, and the smallest distance between the people scoring highest overall and the people scoring lowest. If you are here because a report told you your forehead was your weakest feature, the honest reading of the data is that this is the least consequential place on the face to be weak.
The tightest distribution on the face
Standard deviation measures how far scores scatter around their average. A high number means the feature separates people; a low number means almost everybody lands in the same narrow band.
| Feature | Average | Standard deviation |
|---|---|---|
| Skin | 5.30 | 1.29 |
| Jawline | 5.59 | 1.24 |
| Bone structure | 5.60 | 1.16 |
| Facial harmony | 5.58 | 1.07 |
| Chin | 5.39 | 1.09 |
| Symmetry | 5.62 | 1.01 |
| Lips | 5.65 | 1.00 |
| Cheeks | 5.42 | 0.99 |
| Eyes | 5.97 | 0.99 |
| Eyebrows | 5.94 | 0.94 |
| Nose | 5.36 | 0.93 |
| Forehead | 5.39 | 0.78 |
The forehead sits at the bottom at 0.78, and the distance to the next feature up is larger than the distance between most neighbouring pairs in the table. Skin, at 1.29, scatters people roughly 65% more widely.
In plain terms: skin and jawline are features that sort faces. The forehead mostly does not. Almost everyone is clustered together, slightly below the middle.
The lowest ceiling anywhere
The compression is not symmetric. It is not that low scorers do unusually well on the forehead; it is that high scorers do unusually badly.
Take the 560 people who scored 8.0 or above overall. Their averages on the other eleven features run from 8.00 to 8.90. Their forehead average is 7.66. It is the only feature in the entire dataset where the top of the distribution fails to reach an 8.
Look at the same thing from the other end. The 4,307 people scoring below 5.0 average 4.84 on the forehead, which is the second-highest figure that group posts on any feature. So the strongest faces are pulled down here and the weakest faces are pulled up here, and the two effects meet in the middle.
| Feature | 8+ scorers | Under-5 scorers | Gap |
|---|---|---|---|
| Jawline | 8.89 | 4.53 | 4.36 |
| Bone structure | 8.90 | 4.58 | 4.32 |
| Skin | 8.33 | 4.05 | 4.28 |
| Facial harmony | 8.66 | 4.55 | 4.11 |
| Chin | 8.48 | 4.43 | 4.05 |
| Symmetry | 8.54 | 4.74 | 3.81 |
| Cheeks | 8.25 | 4.50 | 3.75 |
| Eyes | 8.62 | 5.04 | 3.58 |
| Nose | 8.01 | 4.51 | 3.50 |
| Lips | 8.00 | 4.65 | 3.35 |
| Eyebrows | 8.27 | 5.11 | 3.16 |
| Forehead | 7.66 | 4.84 | 2.82 |
A 2.82-point gap is the smallest on the board. The jawline separates the top from the bottom by 4.36 points, more than half again as much. Whatever the forehead is measuring, it is measuring something that high-scoring faces are not notably better at.
So why is it so often the worst feature?
It is. The forehead is the second most common single worst feature, at 15.0% of analyses. Only skin is more common, and skin is far ahead at 38.0%.
These two findings are not in tension, they are the same finding seen twice. Because the forehead average sits slightly below the overall average and the score almost never runs high, it ends up at the bottom of a lot of reports by default. It is the feature most likely to be your lowest number and the feature where being lowest costs the least.
One more piece of context makes that concrete. Across everyone, the average distance between a person's best and worst feature is 1.38 points, and 58.0% of people tie for their worst feature rather than having one clear weak point. Most "worst features" are not dramatic outliers. They are the low end of a narrow band.
Size is not really what is being scored
The question people arrive with is usually about size, and the honest answer is that a forehead score is a proportion measure rather than a measurement in centimetres. It reads how the upper third of the face sits against the middle and lower thirds. A tall forehead on a long face reads differently from the same forehead on a short one, which is why comparing your hairline against a photograph of somebody else tells you very little.
This also sets the limits on what can change. The forehead is partly improvable, but the improvable part is apparent proportion, not size. A fringe, a different parting, or more volume at the sides changes where the visible outline of the face begins. Brow shaping changes where the eye reads the bottom edge of the upper third. None of that alters bone, and the data suggests the available movement is small in any case, because the whole feature only spans 2.82 points from the top of the distribution to the bottom.
What we would not do is treat a forehead score as a reason to consider anything invasive. There are eleven other numbers on the report, several of them with three or four times the range, and two of them genuinely responsive to effort.
What to do with a low forehead score
Read it in context rather than in isolation. If your forehead is your lowest feature and it is 5.1 while your other features sit around 5.6, that is the ordinary shape of a report, not a diagnosis. Only 7.9% of people score 7 or above here and only 2.4% have it as their best feature, so there is no large group of people quietly winning at foreheads that you are being compared against.
If you want the number itself, the forehead rating scores this region on its own, which is more useful than trying to infer it from an overall figure. If you want to know where your effort actually pays, the highest-yield low score to work on is skin, which is both the most common worst feature at 38.0% and the widest-spreading feature on the face; the AI skin analysis tracks that one separately. And to see the full twelve-feature breakdown with your overall score against the distribution, run the face rating tool.
The summary is unglamorous and, we think, genuinely reassuring: the forehead is the one place on the face where nobody is winning much, so losing there costs less than losing anywhere else.
