Facial fifths test: eye spacing and width balance
Last updated: September 2026
The rule of fifths says a face at eye level should divide into five equal eye widths: from the edge of the face to the outer corner of the eye, the eye, the gap between the eyes, the other eye, and out to the other edge. Upload one front-facing photo and the test draws the six vertical lines on your face, gives each fifth as a share of face width, and tells you whether your eyes are set wide, close or classic. Free, in your browser, nothing uploaded.
How to read your fifths
| Eye spacing (gap as a share of one eye width) | Reads as | Notes |
|---|---|---|
| under 100% | Close set | Eyes read intense and the nose reads narrow. Common; rarely a problem below about 90%. |
| 100 to 130% | Classic | The gap is about one eye width, which is where most faces measure with this method. |
| over 130% | Wide set | Eyes read open and the nose reads wide. Above about 145% it starts to show in photos. |
The outer fifths (face edge to outer eye corner) usually come in slightly larger than a fifth because the face edge at eye level includes the temple. What raters notice is the middle three: eye, gap, eye.
How the test measures fifths
A face landmark model finds the four eye corners and the two edges of the face at eye level. The test levels the head, corrects for a small turn (which compresses the far side and is the most common reason the two outer fifths differ), and measures the five segments as shares of the total width. The balance score combines how even the five segments are with how close the eye spacing sits to the classical proportion.

Why eye spacing matters
The eye area is the region raters weigh most, and spacing is the measurement that sets how every other feature in it reads. Close set eyes make a nose look wider and a brow heavier; wide set eyes make a nose look narrower and the face look broader. Neither is better. The classical band is where most faces measure, and faces rated attractive sit throughout it.

How to get an accurate measurement
- Camera at eye level, at arm's length or further. A low camera lengthens the chin and widens the jaw; a high camera shrinks them.
- Even light from the front. A window behind you or a lamp above you puts shadows exactly where the landmarks are.
- Face the camera straight on with a neutral expression, mouth closed, hair off the forehead.
- No filters, no beauty mode, no crop that cuts the chin or the ears.
- Use the same setup when you compare two photos. Different setups produce different numbers on the same face.
FAQ
Is the facial fifths test free?
Yes. It runs in your browser from one photo with no signup and no upload.
What is the rule of fifths?
A face at eye level divides into five equal parts, each the width of one eye: edge to eye, eye, gap, eye, eye to edge.
What is normal eye spacing?
With this method, a gap between 100 and 130 percent of one eye width. Most faces measure there.
Are wide set eyes attractive?
Within the classic band, spacing does not decide attractiveness; faces rated attractive sit throughout it. Very wide or very close spacing changes how the nose and brow read more than it changes the rating itself.
Why do my two outer fifths differ?
Usually a slightly turned head: the far side compresses. Face the camera straight on and retake.
Is my photo uploaded?
No. The measurement runs on your device.
