About
Choosing the right glasses or haircut depends almost entirely on geometry. This Face Shape Analyzer compares four critical measurements of your face to categorize it into one of seven archetypes: Oval, Square, Round, Heart, Oblong, Diamond, or Triangle. Instead of subjective guessing, it uses strict algorithmic ratios.
For example, a Square face is defined by a jawline width roughly equal to the cheekbone width, whereas a Diamond shape requires cheekbones to be significantly wider than both the forehead and jawline. Accurate measurements (in cm or inches) are essential for a correct classification.
Formulas
The algorithm evaluates the relationship between Face Length (L), Forehead Width (fw), Cheekbone Width (cw), and Jawline Width (jw).
