The problem with feature-relative ratios such as the 1.618 mouth-to-nose width ratio is that they don’t work if the reference feature (in this case, the nose) is of subhuman dimensions.
That’s why we need all ratios standardized. All horizontal ratios should be in relation to the bizygomatic width, and all vertical ratios should be in relation to the facial height (hairline to chin distance).
Why are standardized ratios superior? Take the ES ratio for example. Before PSL, people used the rule of thumb that eyes should be one eye width apart. Obviously this doesn't mean shit if you have a narrow PFL. It’s pretty clear that ES ratio mogs “one eye width between” into oblivion.
Standardized ideal horizontal ratios:
*Another mouth width guideline is that the corners of the lips should line up with the inside edges of the irises. Using an iris diameter of 12mm, the result is a mouth width ratio of 0.376 which is very close to 0.38.
