'''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).<ref name="carre">Carré & McCormick and later perception papers; scene glossaries recycle ~1.8–2.1 for men. Different landmarks give different numbers.</ref> 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]].
