Eye spacing describes how far apart your eyes are, measured as the gap between their inner corners — what anatomists call the intercanthal or interocular distance. It's one of the most important horizontal proportions in the face, because the eyes are usually the first thing people look at.
The classic guide is the rule of fifths: looking at the face straight on, its width across the eyes should be about five eye-widths. One eye-width for each eye, one for the gap between them, and one on each side between the outer corner of the eye and the edge of the face. In other words, the space between your eyes should be about as wide as one of your eyes.
This free eye spacing calculator measures both and tells you whether your eyes are ideally spaced, slightly wide-set or close-set.
The calculator runs Google's MediaPipe Face Mesh in your browser (your photo isn't uploaded) and places landmarks on the corners of both eyes and the edges of your face. It then measures:
From those, it calculates two ratios:
| Ratio | Formula | Ideal |
|---|---|---|
| Inter-eye ratio | Gap between your eyes ÷ eye width | 1.0 |
| Rule of fifths | Face width ÷ eye width | 5.0 |
Your score out of 100 is the average of how close you are to both ideals, and your results show your face split into five segments, each expressed in eye-widths, so you can see exactly where the extra or missing space is.
| Score | Result |
|---|---|
| 88–100 | Ideal spacing |
| 72–87 | Well-spaced |
| 55–71 | Slightly off-centre |
| Below 55 | Wide- or close-set |
Separately, the calculator labels your eyes as wide-set if the gap between them is more than 1.2 eye-widths, close-set if it's less than 0.8, and ideally spaced in between.
Wide-set eyes have a gap between them noticeably larger than one eye-width. They're common, and slightly wide-set eyes are often seen in fashion models — they tend to read as open, youthful and approachable. Very wide spacing can make the face look less defined in the middle.
Styling tips: makeup that's darker towards the inner corners of the eyes, and brows that start a little closer to the nose, visually pull the eyes together.
Close-set eyes have a gap smaller than one eye-width. They can give a focused, intense look, and in some faces they make the nose look longer or narrower.
Styling tips: a lighter shade on the inner corners and a darker shade or wing on the outer corners visually widens the gap. Brows that start slightly further from the nose help too.
In everyday use, "wide-set" and "close-set" are cosmetic descriptions. The medical terms hypertelorism (abnormally wide-set eyes) and hypotelorism (abnormally close-set eyes) refer to the distance between the bony eye sockets, diagnosed by a doctor with precise measurements — usually alongside other features. A photo-based calculator can't diagnose them, and having eyes on the wider or closer side of normal is not a medical condition.
For reference, the distance between the pupils (interpupillary distance) averages about 63 mm in adults, according to a 2004 review of the research by Neil Dodgson. Opticians measure it when fitting glasses.
Eye spacing is a good example of averageness: faces with typical proportions tend to be rated as more attractive than faces at either extreme. A 2010 study by Pallett, Link and Lee found that faces looked most attractive when the distance between the pupils was about 46% of face width — close to the average face. That lines up with the rule of fifths.
Eye spacing is also hard to judge by eye, because brows, eyelid shape, nose bridge and eye makeup all change how far apart the eyes seem.
The distance between your eyes is set by the bones of your skull and doesn't change after you're grown. What you can change is how it looks — through brow shaping, makeup and, for glasses wearers, frame choice. Frames with a dark or heavy bridge make wide-set eyes look closer together; a clear or thin bridge makes close-set eyes look further apart.
The ideal is usually given as one eye-width between the eyes — the rule of fifths, where the face is about five eye-widths wide across the eyes. This calculator scores spacing highest when the gap between your eyes equals the width of one eye.
Compare the gap between the inner corners of your eyes with the width of one eye. If the gap is noticeably larger — more than about 1.2 eye-widths — your eyes are wide-set. This calculator measures it for you from a photo.
If the gap between the inner corners of your eyes is noticeably smaller than one eye-width — less than about 0.8 eye-widths — your eyes are close-set.
Slightly wide-set eyes are often considered attractive and are common among models, because they read as open and youthful. Very wide spacing, like very close spacing, is further from the average and tends to be rated a little lower.
Interocular distance is the distance between the eyes. In this calculator it's the gap between the inner corners of your eyes, measured relative to your eye width.
No. Wide-set eyes are a normal cosmetic variation. Hypertelorism is a medical term for an abnormally wide distance between the eye sockets, diagnosed by a doctor with precise measurements.
