Taking the measurement
1
Take a square-on photo
This one is worth getting right. Any rotation of your head reads partly as asymmetry, so square to the camera with a neutral expression.

Read the groups
A low group score with high scores elsewhere usually points at the photo rather than the face. Retake it before drawing conclusions.
Example
Paired landmarks, measured against the midline.
Drawn from the landmarks our own measurement reads off this photo, not
placed by hand. It is a generated face, not a real person, and nothing
here is a verdict about it.
This compares twenty paired landmarks across your face's midline and scores five feature groups out of 100: brows, eyes, nose, mouth and jaw. Symmetry is one of the better-evidenced components of facial attractiveness, and a review in Annual Review of Psychology found it attractive across cultures.
How this is worked out
The midline
An axis from the top of your face outline to the bottom of your chin. Every pair is compared against this line rather than against raw coordinates, so a head turned slightly in frame does not read as a crooked face.
Twenty paired landmarks
Grouped into brows, eyes, nose, mouth and jaw. Each pair should sit equal distances either side of the midline, and the score is how close they come.
Per-group scores
Reported separately as well as combined, because the group scores tell you where the asymmetry is, which the total cannot.
What each measurement is
Reference bands are this tool's own, chosen for the landmarks it uses.
Where research reports a figure it is given separately, with the source,
because the two are different claims. And each one says what actually
moves it, which for most facial measurements is the more useful half.

Research
symmetry is attractive in both sexes and across cultures - Rhodes (2006)
Nobody scores 100. Asymmetry is universal and mostly invisible at conversational distance.
What moves it Aim at the photograph before you aim at your face. A score below the eighties here almost always means the head was turned, and a straight-on shot of an ordinary face lands in the nineties. Of the asymmetry that is real, the postural, dental and muscular kinds can be addressed by a physiotherapist, dentist or orthodontist; the skeletal kind does not move. Facial exercises marketed for symmetry have no evidence behind them, which is worth knowing before a year goes into them.
Brows /100
Formula
3 paired landmarks against the midline
What moves it Brow asymmetry is often muscular and habitual, which makes it one of the few here that can shift.
Eyes /100
Formula
4 paired landmarks against the midline
Nose /100
Formula
3 paired landmarks against the midline
Mouth /100
Formula
3 paired landmarks against the midline
Jaw /100
Formula
4 paired landmarks against the midline
Usually the lowest group, because the jaw outline is where head rotation shows first.
This compares twenty paired landmarks across your face’s midline and scores five
feature groups: brows, eyes, nose, mouth and jaw.
Symmetry is one of the few measurements in looksmaxxing where the research is
genuinely strong, so it is worth stating plainly before the caveats.
What the research found
Rhodes reviewed the field in Annual Review of Psychology in 2006, combining a
critical review with meta-analyses. The conclusion: averageness, symmetry and
sexual dimorphism are all attractive, in both male and female faces, and across
cultures.
She also noted that preferences appear early in development and that
cross-cultural agreement undercuts the idea that beauty standards are purely
arbitrary cultural inventions.
That is a top-tier journal and a review rather than a single study, which is why
symmetry carries the heaviest weight in our
attractiveness test. The weights there follow the
evidence grading rather than tradition.
The honest follow-up belongs next to it: a population-level effect is not a
prediction about one person, and Rhodes does not claim otherwise.
Nobody is symmetrical
This is the part most symmetry tools leave out.
Facial asymmetry is universal. Everyone has it, most of it is invisible at
conversational distance, and a tool that finds some in your face is working
rather than diagnosing.
Mirrored composites are misleading and this tool deliberately does not use
them. Doubling one side of a face doubles every difference simultaneously, and
the result looks strange even for people whose faces do not. It is a party trick
that reliably makes ordinary faces look wrong, which is a poor foundation for a
measurement.
Why the midline matters, and what it protects you from
Every pair here is compared against an axis running from the top of your face to
your chin, rather than against raw coordinates.
That choice has a consequence worth knowing: a head turned slightly in frame
reads as less asymmetric than a naive measurement would make it. The tool
under-reports rather than over-reports.
That is the failure worth having. This returns a number about a photograph, and
a photograph taken at a slight angle should not be allowed to tell somebody
their face is crooked.
It does not remove the problem entirely. Rotation is still the single biggest
cause of a low score, so if one group comes back far below the others, retake
the photo square-on before believing it.
What moves and what does not
Postural and dental asymmetry can shift, and a dentist, orthodontist or
physiotherapist is the right person to look at those.
Skeletal asymmetry does not change without surgery, which is an adult
decision for a qualified surgeon with real risks attached.
Exercises marketed for facial symmetry do not have evidence behind them, and
saying so is cheaper than finding out over a year.
Where to go next
The attractiveness test shows how this score combines
with averageness and balance, weighted by evidence. The
face shape detector works on the same outline, and the
canthal tilt calculator covers the eye area in more
detail than the group score here can.
This scores it out of 100 across five feature groups. Bear in mind that nobody is perfectly symmetrical and a score in the high nineties is already unusual, mostly because photography introduces error of its own.
Does facial symmetry actually matter?
It is one of the better-evidenced parts of this field. Rhodes reviewed the literature in Annual Review of Psychology and found symmetry, averageness and sexual dimorphism all attractive in both sexes and across cultures.
Is anyone perfectly symmetrical?
No. Asymmetry is universal and largely invisible at normal conversational distance. A measurement that finds it is working correctly, not finding a problem.
Why is my symmetry score low?
Check the photo first. Head rotation is the biggest single cause of a low score, and it is also the easiest to fix. If one feature group is far below the others, that pattern usually points at the camera.
Can you improve facial symmetry?
Some asymmetry is postural, dental or muscular and a professional can address those. Most of it is skeletal and does not change. Exercises marketed for it do not have evidence behind them.
Does chewing on one side cause asymmetry?
Chewing loads the masseter, and a muscle worked harder on one side can grow thicker on that side, so a visible difference is plausible. What we have not found is a study measuring how much. A dentist who can look at you is better placed than a calculator here.
What is a good symmetry score?
Nobody scores 100 and a straight-on photo of an ordinary face usually lands in the nineties, because asymmetry is universal and the measurement is sensitive. Scores below the eighties on this tool almost always mean the head was turned rather than that the face is unusual. Retake the photo square-on before reading anything into it.
Why do the two halves of my face look so different mirrored?
Mirrored composites exaggerate asymmetry dramatically, because doubling one side doubles every difference at once. They make an ordinary face look strange, which is why this tool scores landmarks instead.
Does symmetry change with age?
Soft tissue changes over a lifetime and sun exposure is unevenly distributed, so some drift is expected. We do not have a vetted figure for how much.
Is my photo uploaded?
No. Everything runs in your browser and the content security policy blocks connections to any other domain.
