Summary

The chin to philtrum ratio compares the height of the chin with the length of the philtrum, the groove between the nose and upper lip, and on Jeffrey Dean Morgan's face it measures 2.38x, scoring 10.0. Chin height relative to philtrum length is what determines chin harmony, with balanced proportions considered ideal and slightly taller chins favoring male dimorphism. His value sits inside its ideal range of 2.15 to 2.45x and is higher than 60% of the men on the wiki, with 35% of men measuring inside the same range. He shares this exact ratio with Hugh Laurie and Anthony Mackie, while Casey Neistat sits at the highest end at 3.73x and Lee Jung-jae at the lowest at 1.50x.
