Midface ratio from a front-facing photo
A midface ratio is the distance between the pupils divided by the height from that line to the top edge of the upper lip. This page measures the midface ratio in your browser from one front-facing photo. The number is a geometric estimate of that photo, not a judgment of you.
Measure your midface ratio
Tick the box above to choose a photo.
Your photo stays on your device. It is analyzed in your browser and never uploaded.
For the best result
- Face the camera straight on and keep your head level.
- Keep a neutral expression with your lips closed.
- Use even light, and keep hair and glasses off your face.
It is free, needs no account, and the photo is not sent off your device.
What the midface ratio is
The midface ratio uses two lengths. Take the distance between the two pupils. Divide it by the height from the pupil line down to the top edge of the upper lip. That quotient is the midface ratio.
A larger midface ratio means the height is smaller next to the eye spacing, so the midface in the photo is relatively short. A smaller midface ratio means the height is larger next to the eye spacing, so the midface in the photo is relatively long. Skin, hair, teeth, and expression are not in the formula.
On this site, the midface ratio is one of 12 ratios in the home page psl rating. It sits in the Harmony group. The home page also returns a score from 0 to 8, a tier, and four category scores. This page reports the midface ratio only.
How this tool measures the midface ratio
This midface ratio calculator runs in your browser. Pick the male version or the female version. Check the box that says "I'm 18 or older and this is a photo of my own face." Upload a front-facing photo, or take one with your camera. The midface ratio does not run until that box is checked. The photo stays on your device.
The browser finds the pupils and the top edge of the upper lip. It draws the line between the pupils, and a vertical line from that line down to the upper lip. The midface ratio is the first length divided by the second, shown to three decimal places. The lines stay on the photo.
Side to side tilt means the head leaning toward one shoulder. That lean is already removed from the midface ratio. Looking up, looking down, and turning the face away are not removed. Use a front-facing photo, eyes toward the camera, mouth at rest. The same photo on the same device gives the same midface ratio. A different photo, different light, or a different angle can change it.
Men's and women's midface ratio ranges
The formula for the midface ratio is the same on both versions. The reference range changes. The male version uses 0.98 to 1.02. The female version uses 0.98 to 1.06. Read the band for the version you picked.
Above the band, the midface in the photo is shorter relative to the eye spacing than that range. Below the band, it is longer relative to the eye spacing. A number inside the band sits in the reference range. As a plain example, 1.04 is above the male band and inside the female band. The example only shows where 1.04 falls. It does not compare you with anyone else.
Long and compact midface
Looksmaxxing talk uses compact midface, and sometimes short midface, for a midface that is short relative to the eyes. Here, that shorter midface is a higher midface ratio. The height under the pupil line is the smaller number in the division, so the midface ratio comes out larger.
A long midface is the other proportion. The height from the pupil line to the upper lip is large next to the eye spacing, so the midface ratio comes out smaller. Those names are labels for the proportion in the photo. A midface ratio outside the reference range is not a grade.
This page will not tell you how to shorten a midface. It does not recommend a procedure, a treatment, or a product. If you have a medical concern, ask a licensed professional.
What moves a midface ratio reading
The midface ratio moves when the photo changes the two lengths, or when the points land in a different place. These conditions move a midface ratio:
- Looking up or looking down changes the apparent height from the pupil line to the upper lip.
- A smile lifts the upper lip, so the height in the formula gets shorter and the midface ratio tends to rise.
- Eyes off the camera can shift the pupil points, and the reading can shift with them.
- A close shot on a wide angle lens can stretch the middle of the face, so both lengths can change.
- A hard shadow on the lip, or glare on the eyes, can move where the lines land.
The same photo on the same device gives the same midface ratio. This page does not claim a match on a second device.
What a midface ratio cannot tell you
A midface ratio is not a judgment of you. It is two lengths in one photo. The midface ratio is not a medical finding, and it is not a psychological finding. Outside the reference range, the proportion in that photo simply sits outside the band you selected.
The midface ratio also cannot tell you to change your face. This site does not generate a new face, and it does not edit your photo into a different face. You get the photo you added, the two lines, and the midface ratio. The page does not show an edited face.
One midface ratio is not the home page score from 0 to 8. Eye angle is a separate reading on the canthal tilt page. Jaw angle is a separate reading on the gonial angle page. This page stays with the midface ratio.
