The Classical Facial Thirds (Rule of Thirds)
In aesthetic surgery and classical art, an idealized face is vertically divided into three equal segments:
- Upper Third: From the trichion (forehead hairline) to the glabella (inter-eyebrow point).
- Middle Third: From the glabella to the subnasale (base of the columella below the nose).
- Lower Third: From the subnasale to the menton (lowest contour point of the chin).
Understanding fWHR (Facial Width-to-Height Ratio)
fWHR is an extensively researched metric in anthropometry. It is calculated by dividing bizygomatic width (distance between the outer cheekbones) by midface height (distance from upper eyelid/brow down to the upper lip line). For golden proportion analysis, check our Golden Ratio Face Calculator.
Frequently Asked Questions
Facial thirds divide the face into three vertical intervals: forehead (trichion to glabella), midface (glabella to subnasale), and lower face (subnasale to menton).
fWHR is the ratio of bizygomatic cheek width divided by upper facial height (eyebrow level to upper lip). It is widely studied in craniofacial anthropometry.
