Jaw width to cheekbone width
The width of the jaw at the angle of the mandible, divided by the width across the cheekbones. Lower values read as a tapered face, higher values as a squarer one.
Educational method only. Personal numerical values are currently unavailable in the free preview and reports under the current offer. Existing purchases retain their purchased scope.
Also called face taper, bigonial to bizygomatic ratio.
Reference range
None.
We have not validated a population reference interval for this photographic method. Published anatomical measurements do not automatically validate mesh-based estimates.
How we calculate it
Distance between the left and right jaw-angle landmarks over the distance between the left and right cheekbone landmarks, on the roll-corrected mesh.
What moves the number
Head turn most of all — even a small yaw foreshortens one side of the jaw. Also weight, jaw clenching, and whether the hair or a collar obscures the jaw angle.
What it cannot tell you
It cannot separate bone from the soft tissue sitting over it, and it does not identify a face shape category. Both tapered and square faces are common and neither is a defect, and with no published population range behind it the number describes your photograph rather than placing you anywhere.
References
None. We have not found a published population range for this measurement, so there is nothing here to cite. We would rather show an empty list than a decorative one.
A width ratio gives one description of an image. Styling decisions need more context.
