Frequently Asked Questions
What is the gonial angle?
The gonial angle is the angle formed at the corner of your jaw (the gonion), where the vertical part of the jaw meets the horizontal part along your jawline. It's a major driver of how defined and masculine a jaw looks — a key looksmaxxing metric measured from a side-profile photo.
What is the ideal gonial angle?
For men, a gonial angle in the roughly 110-120° range is considered ideal — sharp enough to give a defined, angular jaw. A higher (wider/more obtuse) angle reads as a softer, more rounded jaw; a very low angle can look overly square. Women's ideals sit slightly higher (softer).
How do I measure my gonial angle?
Upload a clear side-profile photo. The AI locates the jaw landmarks and calculates your gonial angle automatically, then shows how it compares to the ideal range and how it feeds your jawline and overall score.
Can I improve my gonial angle?
The bony angle itself is mostly fixed, but you can dramatically change how defined your jaw looks: lower body-fat and reduce under-chin fullness, build the masseter with chewing/jaw training, fix tongue posture (mewing), and reduce facial bloat. The scan shows what will sharpen your jawline most.
