Eye spacing
The gap between your eyes relative to the width of one eye (the classic "one eye-width apart" check).
Why it matters
Eye spacing strongly shapes how harmonious and "averaged" the centre of the face looks — a key driver of attractiveness perception.
What eye spacing actually measures
Eye spacing describes the horizontal gap between the inner corners of your eyes, judged against the width of a single eye. In anatomy the inner corner is the medial canthus, where the upper and lower lids meet beside the bridge of the nose; the inter-canthal distance is simply the span from one medial canthus to the other. On its own that span tells you little, because a larger face carries larger features, so the metric divides it by the average width of one eye to give a scale-free ratio.
This is the quantity behind the familiar studio rule that the eyes sit about 'one eye-width apart'. The tool reads the landmark points for both inner corners and both eye openings from the face mesh, corrects for any head tilt, and reports the gap as a multiple of one eye-width. Because everything is relative to your own eye, the number does not change just because you move closer to or further from the camera.
Why the centre of the face reads on it
The eyes are usually the first region a viewer settles on, and the spacing between them sets the rhythm of the whole central face. When the gap is close to the width of an eye, the brows, nose bridge and eyes tend to feel evenly distributed; when it is much wider or much narrower the midface can read as either spread out or crowded. That is why eye spacing appears in almost every classical drawing canon as a proportion worth checking.
It helps to be precise about what these conventions are. Farkas 1994 catalogued head and face measurements across large samples, and that work is used here as an anthropometric reference point, not as proof that one spacing is objectively more beautiful than another. Spacing is one harmony cue among many, and it carries no information about a person's character or worth.
The conventional ideal and its honest limits
The neoclassical canon puts the inner-eye gap at exactly one eye-width. On the measurement mesh used here that 'equal' point actually lands near a ratio of 1.24 rather than a tidy 1.0, an artefact of where the landmarks fall, and the scored band runs roughly 1.1 to 1.28. The band leans slightly below the mesh average because, among the rated faces this tool was checked against, marginally closer-set eyes tracked very slightly higher ratings.
The canon itself is openly debated. Farkas et al. 1985, in their revision of the neoclassical canons, found that these tidy equalities rarely hold exactly in real adults and vary with ancestry and sex. Treat 'one eye-width' as a useful reference line rather than a target you must hit, and remember that many widely admired faces sit outside it.
Reading your own result, and what can change
A result a little inside or outside the band is unremarkable; eye spacing varies normally, and head tilt or an off-centre camera can shift the reading by more than the real difference between two people. For a fair number, use a relaxed, front-on photo taken at eye level, and treat the figure as a description of your proportions rather than a grade.
Eye spacing is set by the position of the bony orbits, so it is essentially fixed structure. The honest levers are about how it reads, not what it is: brow shaping and eye makeup can nudge the apparent gap a little, and framing or hairstyle can rebalance the surrounding face. Surgery that repositions the orbits themselves exists only for medical reasons and is not a cosmetic procedure; it is noted here only for completeness.
Typical range
~one eye-width between the eyes (mesh-calibrated)
Inter-eye gap relative to one eye width. Classically the gap between the eyes equals the width of one eye.
What your reading means
- Typical
- Your eyes sit about one eye-width apart — the classical harmonious spacing.
- Less common
- Your eye spacing is close to the one-eye-width ideal, with a slight deviation.
- Distinctive
- Your eyes sit noticeably closer together or further apart than the one-eye-width convention.
How we measured it
We measure the distance between the inner eye corners and divide it by the average width of your eyes, after correcting for any head tilt.
The evidence
The classic "equal to one eye width" ideal lands near ~1.24 on the mesh (not 1.0). In our rated faces, closer-set eyes tracked slightly higher ratings, so the band leans below the mesh median.
