The following ratios between facial triangles are calculated: The formula used to determine the extent to which the proportions of an adolescent or adult face approximate the proportions of faces commonly regarded as having classical beauty is: CAUTION: The ratings produced by Rating Faces may not be used to solicit dates.

It is tempting to collect data about the proportions of faces, and to measure that data against well known faces about which there is common agreement as to beauty or lack thereof. Of course, any attempt to use a mathematical evaluation of facial structure as a means of determining beauty is at best just an amusement controlled by entirely random and woeful illusions. Nevertheless, Rating Faces provides that amusement by calculating the degree to which the facial proportion ratios of any face approach the ratios of people who are commonly regarded as reflecting classic beauty. Rating Faces is simple to use: 1. Import a picture of a face whose proportions you want to evaluate. 2. Click at the exact center tip of the nose to divide the facial graphic into quadrants. 3. Then just click your mouse at the locations indicated by the Rating Faces automated guide. The format of the app is intended to calculate extremely accurate facial proportions, not merely to use a grid to scan the general contours of your face. Rating Faces also offers an accurate means by which to compare facial proportions between family members, friends, and folks with different ethnic backgrounds. Just set the triangle proportion lines of one person's face and then click the thumbnail pictures to overlay those lines on other faces for comparison. Data is saved for the proportions of each face that is measured, reflecting the ratios between the 4 most illuminating and accurate triangles of facial measurements: the chin triangle, the mouth triangle, the inner eye triangle, and the outer eye triangle, along with 6 separate linear dimensions (LT).
