00Facial proportions
Facial proportions: measure your fWHR, midface ratio and more
Take or upload one front-facing selfie. We measure seven ratios, including fWHR and the midface ratio, plus your facial fifths and thirds. Every number is drawn on your photo and shown beside the range most real faces fall in. Your photo stays on your device.

01The seven facial proportions we measure
Each facial proportion is one length divided by another, both measured between points found on your face. Widths are straight lines; heights are measured along your face, so a slightly tilted photo reads the same.
- fWHR
- Facial width-to-height ratio: the width across your cheekbones, divided by the height from between your inner brows down to your upper lip.
- Midface ratio
- The distance between the centres of your irises, divided by the height from the point between them down to your upper lip.
- Face length ÷ width
- From the top of your forehead (as far as we can detect it, not your hairline) down to your chin, divided by the width across your cheekbones.
- Jaw ÷ cheekbone width
- The width across the corners of your jaw, divided by the width across your cheekbones.
- Eye spacing
- The gap between the inner corners of your eyes, divided by the average width of one eye.
- Mouth ÷ face width
- The width of your mouth from corner to corner, divided by the width across your cheekbones.
- Nose ÷ mouth width
- The width of the base of your nose, divided by the width of your mouth.
02fWHR: facial width-to-height ratio
fWHR divides the width across your cheekbones by the height of your upper face. Research papers measure that height in different ways; we use the inner brows to the upper lip, the usual version from the original study. In our reference photos most faces read between 1.59 and 1.87. Studies linking fWHR to personality or behaviour find small, mixed effects, so this fWHR calculator reports a measurement, not a verdict on you.
03The midface ratio
The midface ratio here is the common online version: the distance between your pupils divided by the height from your pupils to your upper lip. A higher number means a shorter-looking midface for its width. Most faces in our reference photos read between 0.96 and 1.15. Other midface ratio calculators use other points, so compare numbers only between tools that use the same formula.
04Facial fifths and thirds
The rule of fifths, from drawing and portrait guides, splits the width of a face into five parts: each eye, the gap between them, and the space out to each cheek edge. The rule says each is one fifth (20%). Real faces rarely split evenly: in our reference photos the gap between the eyes was usually the widest part, around 24%. The facial thirds split face length at the brows and the base of the nose; your result shows them as one line.
05Reference ranges, not ideal facial proportions
Each range is where the middle 80% of faces fell in a set of 102 front-facing photos of adults we measured the same way. Falling outside it means your proportion is less common in those photos, not that it is wrong. There is no proven set of ideal facial proportions, and a facial harmony test can't turn these numbers into a beauty score. None of them goes into your attractiveness score.
06How to take the photo
- 01Face the camera straight on with the phone at eye level. Tilting your chin up or down changes every height, including fWHR and the midface ratio.
- 02Keep a neutral face with your lips relaxed: a smile widens your mouth.
- 03Look at the camera with your eyes open, so your irises can be found.
- 04Pull hair back off your forehead and cheeks.
- 05Hold the phone at arm's length; very close photos stretch the middle of the face.
07How the facial proportions are measured, and the limits
Your browser finds 478 points on your face and measures between named points: cheekbones, jaw corners, inner brows, iris centres, eye and mouth corners, the sides of your nose, the top of your upper lip and your chin. Every number is a ratio, so it doesn't depend on photo size. It is still one 2D photo: camera distance, head angle, expression and hair all move the points. The top of the face we can detect is not your hairline. If a point can't be found, that proportion shows as missing rather than as a guess.
08Facial proportions questions
01How does the facial proportions test work?
Take one straight-on selfie with a neutral face. Your browser finds 478 points on your face, measures seven ratios, including fWHR and the midface ratio, plus your facial fifths and thirds, and draws each one on your photo next to the range most faces fall in.
02What are ideal facial proportions?
There isn't one set. Drawing guides use rules such as equal fifths and thirds, but measured faces rarely match them, and attractive faces come in many proportions. We show where your numbers sit among real faces instead of against an ideal.
03What is a normal fWHR?
With our formula (cheekbone width ÷ inner brows to upper lip), most faces in our reference photos read between 1.59 and 1.87, with a median of 1.72. Published studies report values from about 1.6 to 2.2, but they measure height from different points, so only compare numbers that use the same formula.
04What is a good midface ratio?
There isn't a good or bad one. With the pupil-distance formula, values around 1.0 are common: most faces in our reference photos read between 0.96 and 1.15. The number changes with camera angle, so take photos at eye level.
05Is this a facial harmony test?
It measures the proportions facial harmony tests are built on, but it doesn't add them into one harmony score. Each proportion is shown on its own, with its formula and lines, so you can see what was measured.
06Is my photo uploaded?
No. The test runs entirely in your browser and never uploads your photo or the points found on your face.
