Jaw Gonial Angle Guide
Learn what the gonial (jaw) angle is, typical ranges for men and women, and calculate yours from a side-profile photo with AI.
What is the gonial angle?
The gonial angle is formed at the corner of the mandible (jaw), where the body of the jaw meets the ascending ramus. It strongly influences how square, tapered, or V-shaped your jaw looks in profile and front view.
Typical ranges
Ranges vary by sex and ethnicity. Men often show slightly more obtuse angles and wider jaws; women often show sharper taper toward the chin. “Ideal” is context-dependent — harmony with chin, ramus height, and facial width matters.
- Very acute angles can read as overly square or heavy
- Very obtuse angles can read as soft or undefined
- Ramus length and chin projection change the same angle’s visual effect
Measure with a side photo
Use a true 90° side profile with neutral head position. Our jaw angle calculator estimates the gonial angle from your photo for comparison against common reference ranges.
