Bizygomatic width
The visible cheekbone-to-cheekbone width at its widest measured point.
Local ratio tool
fWHR Calculator
fWHR is bizygomatic width divided by upper-face height. This calculator measures both, prints them, and shows where the result sits relative to published adult ranges.

Calculate your fWHR
Cheekbone width and brow-to-lip height are measured locally and reported next to the ratio.

What it measures
Evidence behind this result
The output is built from inspectable photo geometry and a separate image-quality signal.
Upper-face height
The vertical distance from the brow line down to the top of the upper lip.
Range context
The value is placed against the roughly 1.7–2.1 range that published adult samples cluster in.

How this tool works
Detect
A local model places the cheek, brow and lip landmarks.
Align
The height is taken in an eye-line-aligned frame to reduce roll sensitivity.
Divide
Width divided by height produces the scale-independent fWHR.

What the result cannot tell you
01
Research linking fWHR to behaviour or personality is contested and has failed to replicate consistently; treat it as a measurement, not a prediction.
02
Soft-tissue landmarks in a photo are not the skeletal points used in the original studies.
03
Weight, age, expression and camera perspective all move the visible ratio.
What is fWHR?+
Facial width-to-height ratio: the width of the face across the cheekbones divided by the height from the brow line to the upper lip. It is a proportion measurement, usually falling between about 1.7 and 2.1 in adults.
Does a higher fWHR mean anything about personality?+
No conclusion you should rely on. The studies that popularised that idea have been widely challenged and have not replicated reliably. This page reports the geometry only.
Why does my fWHR change between photos?+
Smiling widens the visible cheek line, and camera distance changes vertical compression. Use a neutral expression and consistent framing when comparing values.
