AI Eye Shape Detector: Almond, Hooded, Upturned, Downturned

This page is part of our AI facial analysis, and it defines every class by measurement, with a self-check you can run in a mirror. Your free scan reads 478 landmarks on your device and scores the symmetry of the eye region today; the eye shape class itself, with the three readings behind it, is measured in your Attractiveness Report. A class is a description, not a verdict.

The Short Version

The Three Readings That Decide Eye Shape

The eye opening, the palpebral fissure in clinical language, is wider than it is tall in every published adult sample. In 200 South Indian adults aged 18 to 26, it averaged about 30 to 31 mm wide against 11 to 12 mm tall, roughly two and a half times wider than tall, with corners tilted a few degrees upward on average. Every class below is a different way of departing from that baseline.

Reading one: crease visibility

Crease visibility separates the almond and round family from hooded and monolid eyes. The crease is the fold where the lid doubles as the eye opens; the lid platform is the strip of skin between crease and lash line. A hooded eye has a crease with soft tissue above it draping over the platform. A monolid has no crease line at all. Both are ordinary anatomy with published numbers behind them: in one Malaysian study, every Malay volunteer and 70.1% of Chinese volunteers had a crease on both eyes, with mean crease heights of 8.33 mm and 4.91 mm. Crease height and pretarsal show also differ by race, sex and age in the American sample that measured them.

Reading two: corner angle

Corner angle separates upturned from downturned eyes, and it is the one reading with its own instrument on this site. The angle of the line from inner corner to outer corner is your canthal tilt: positive means the outer corner sits higher, negative means it sits lower. That free tool measures the angle in degrees, per eye, on your device. Upturned is a positive tilt and downturned is a negative one, so this mirror question has a number behind it.

Reading three: width against height

Width against height separates almond from round. An almond eye is clearly wider than tall, and its outline tapers toward both corners. A round eye carries more height for the same width, holds a more open curve, and often shows white above or below the iris. Depth is the quiet fourth reading: deep-set eyes sit farther back in the orbit, under a stronger brow shadow. Depth is also the reading a flat photograph handles worst, which is worth remembering before you accept any 2D verdict about it.

The Six Eye Shapes, Defined by Measurement

Each eye shape is defined by which reading departs from the baseline, and the table states that reading for all six classes, plus monolid, which earns its own row because a crease reading is not an outline reading.

Real eyes hold more than one label at once. Hooded and downturned describe different readings, so one eye can be both, and a chart that forces a single answer is rounding you to its nearest row. When two rows fit, read the crease first and the corner angle second.

How to Find Your Eye Shape With a Mirror and a Photo

You can find your eye shape in about two minutes with one straight-on photo and three checks.

1. Photograph your face straight on with the lens at eye height, expression flat, hair clear of both eyes.
2. Check the crease: a visible lid platform points to almond or round, a fold covering the platform reads hooded, no crease line reads monolid.
3. Check the corners against a horizontal drawn between your two inner corners: outer corners above it read upturned, below it downturned.
4. Compare width to height: closer to three times wider than tall, with tapered corners, reads almond; taller and more open reads round.
5. Check depth in side light: a strong brow shadow across the upper lid points to deep-set.

Write down every label that fits rather than the one you were hoping for. The corner check is the one you never have to eyeball, because the canthal tilt tool returns it in degrees while you wait.

What the Free Scan Measures Around Your Eyes

The free scan measures the symmetry of your paired eye landmarks today, and it does not print an eye shape class. What it does measure is real and checkable: it maps 478 landmarks in your browser, scores symmetry against a fitted midline, and uses your eye width as the ruler for its facial fifths reading. Symmetry, thirds, fifths, golden ratio proximity and harmony come back scored in about a second, and photos never leave your browser. The full face analysis explains all five components in one place.

The classification itself (crease show, corner angle in degrees, and width against height, resolved into a named class) is measured in your Attractiveness Report, beside every other measurement and the weight each one carries.

What the Evidence Says About Eye Shape and Attractiveness

The evidence says less than the internet does: no published study ranks the six eye shape classes against each other. The rating literature that exists measures continuous features, mostly corner angle, on edited photographs, and its two strongest studies point in opposite directions: the same kind of edit one panel preferred, another panel marked down. Those studies sit, with citations, on the canthal tilt page.

Population norms are just as unhelpful to a verdict. Fissure dimensions and inclination differ by sex and by population in every sample that measured them, so most attractive eye shape is a question with no stable reference group. An industry that retires eye shapes every few seasons has still not agreed on a winner. Measurement is slower, and calmer.

Can You Change Your Eye Shape?

You cannot change your eye shape at home, because the orbital bone, the canthal tendons and the lid structures that set all three readings do not respond to exercise or massage. What changes is the read: liner, lash and brow work shift how crease and corner register in a photograph, and eyeliner matched to your canthal tilt covers the technique. Hooding also drifts slowly with age as the soft tissue above the crease descends. Eyelid surgery exists and belongs with a qualified clinician after an examination: a lid that droops suddenly, changes on one side only, or gets in the way of vision is a question for that clinician, not for a chart.

What This Score Cannot Tell You

The measurement conventions and the failure modes sit in how we measure, and where the measurement fails.

You Know Your Eye Shape: What Next?

Treat the label as one photograph's answer and confirm it before you act on it: retake the photo at eye level in different light, and keep every label that survives both frames. The corner reading is the one worth pinning down in degrees, since it moves with camera height. And a class is not a score: what a 1-10 attractiveness score really means covers that scale separately, including what your score means and what it cannot.

Not medical advice. This is a chart and a measurement method for a photo, not a diagnosis, a clinical assessment, or a verdict on you.
