Frequently Asked Questions

How is face shape determined?

Face shape is classified by comparing the relative widths of your forehead, cheekbones, and jawline against your face length -- for example, a face much longer than it is wide tends toward Oblong, while roughly equal widths and length suggest Round or Square depending on how sharp the jawline is.
