FWHR calculator: facial width to height ratio
Last updated: September 2026
FWHR is the width of the face at the cheekbones divided by the height from the upper lip to the eyelids. It is the one facial measurement with a research literature behind it, linking wider faces to perceived dominance and aggression. Upload one front-facing photo and the calculator measures yours from 478 landmarks in your browser and tells you where it sits. Free, no signup, nothing uploaded.
What your FWHR means
| FWHR | Reads as | Notes |
|---|---|---|
| under 1.8 | Narrow | A longer face for its width. Reads as elegant or delicate. |
| 1.8 to 2.0 | Average | Where most adult faces measure. |
| 2.0 to 2.15 | Wide | A broad midface. Reads as dominant and, in the studies, is rated as more aggressive and more trustworthy at the same time, depending on the context. |
| above 2.15 | Very wide | Uncommon. Often a short midface rather than an unusually wide face. |
How the calculator measures FWHR
The standard definition is bizygomatic width (cheekbone to cheekbone) over upper face height (the top of the upper lip to the highest point of the eyelids). A face landmark model finds the cheek edges, the upper lip and the upper eyelids; the test levels and frontalizes the face and divides one by the other. The result matches the definition used in the research, so you can compare your number with the published averages.

What the research says, and what it does not
Higher FWHR has been associated in studies with perceived dominance, with aggression ratings from strangers, and in some samples with testosterone exposure during growth. Later, larger studies found the effects small and inconsistent, and the link to actual behaviour weak. What holds up is perception: people rate wider faces as more dominant and more formidable. It is not an attractiveness measure, and on the PSL scale a very wide face can read as a short midface, which raters mark down. Treat FWHR as a description of your face type, not a score.

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 FWHR calculator free?
Yes. It runs in your browser from one photo with no signup and no upload.
What is a normal FWHR?
Most adult faces measure between 1.8 and 2.0 with the standard definition (cheekbone width over lip to eyelid height).
Is a high FWHR attractive?
Not by itself. It is linked to perceived dominance, not to attractiveness ratings. A very high FWHR often means a short midface, which raters mark down.
How do I measure FWHR myself?
On a front photo, measure the distance between the cheekbones and divide by the distance from the top of the upper lip to the top of the eyelids. The calculator places those points the same way each time.
Does FWHR change?
Weight adds width at the cheeks and raises it slightly. The bone does not change.
Is my photo uploaded?
No. The measurement runs on your device.
