Facial width-to-height ratio
 Facial thirds charcoal study (Astra, 2026). FWHR is bizygomatic width over upper-face height — a measurement, not a PSL score.

Facial width-to-height ratio (fWHR) is bizygomatic width (cheekbone to cheekbone) divided by upper-face height (usually brow/upper-lid landmarks to upper lip — studies disagree on anchors).[1] Social-psychology papers have linked higher male fWHR to ratings of dominance and aggression; effect sizes are modest and contested. Looksmaxxing treats a high fWHR as “more Chad,” i.e. a wider, squarer midface.
It is not a PSL score. It does not measure jaw. Changing it in an adult means width (implants, fat) or the vertical denominator (hairline, lip position, surgery) — not a chewing block.
What it is not
A rating app’s FWHR is a template match. Anthropometry is calipers or a calibrated photo. See bizygomatic width and facial thirds.
