The relationship of vertical facial height to facial width is an important indicator of overall facial shape.

There are three methods of evaluating the vertical facial height - to - width proportion. These may be presented as proportions, percentages or indices: • craniofacial height (vertex - menton) to facial width (zy -Zy): the craniofacial height is measured from vertex (the highest point of the head, with the subject in nhp) to menton. Bizygomatic facial width, measured from the most lateral point of the soft tissue overlying each zygomatic arch (zygion), is approximately 60% of vertical craniofacial height. • physiognomical face height (trichion - menton) to facial width (zy - zy): bizygomatic facial width is approximately 70 – 75% of vertical facial height. In addition, bitemporal width, measured from the most lateral point on each side of the forehead, is 80 – 85% of bizygomatic width. Bigonial width, measured from the soft tissue overlying the most lateral point of each mandibular angle (soft tissue gonion), is usually 70 – 75% of bizygomatic width. • morphological face height (nasion - menton) to facial .Width (zy - zy).
