We analyzed 12,847 faces to find the exact gonial angle range that correlates with peak attractiveness — for both men and women.
"What jawline angle should I aim for?" is the most common question we get from jawline test users. The answer is not simply "as sharp as possible." Our data reveals a specific sweet spot that differs between men and women — and going below it actually hurts your score. Here is what 12,847 measured faces tell us about the ideal gonial angle.
Key finding
The ideal gonial angle is 120-130° for men and 125-135° for women. Angles sharper than 115° scored 12% lower than the ideal range, proving that "sharper is always better" is a myth. The sweet spot balances definition with facial harmony.
The gonial angle (also called the mandibular angle or jawline angle) is formed at the corner of the jaw where the vertical ramus meets the horizontal body of the mandible. In simpler terms, it is the angle at the "corner" of your jaw — the point just below your ear where the jaw turns from going backward to going forward toward your chin.
A smaller (sharper) angle creates a more defined, angular jawline. A larger (wider) angle creates a softer, rounder jaw appearance. The average human gonial angle is approximately 128° at age 20, and it tends to increase (become wider) with age due to bone resorption and muscle atrophy.
Our AI measures this angle automatically from a front-facing photo by detecting the mandibular landmarks. The jawline test gives you your exact angle in degrees and compares it to the distribution across our dataset.

We categorized measured gonial angles into ranges and correlated them with overall facial attractiveness scores. Here is what the data shows:
Very sharp
Too angular, can appear harsh or gaunt
Sharp
Strong definition, works well with masculine faces
Ideal (men)
Peak attractiveness range for male faces
Ideal (women)
Peak attractiveness range for female faces
Average
Most common range, room for improvement
Wide
Weak jawline definition, often improvable
The key insight is that the relationship is not linear. Going from 140° to 130° produces a significant score increase. Going from 130° to 120° produces a moderate increase. But going below 115° actually decreases scores — the face starts to look overly angular, gaunt, or harsh. The ideal is defined, but balanced.
The 5-degree offset between the male ideal (120-130°) and female ideal (125-135°) aligns with research on sexual dimorphism in facial attractiveness. Sharper jawlines signal higher testosterone and are disproportionately valued in male faces. Slightly softer jawlines in women signal femininity and are associated with higher estrogen markers.
This does not mean women should avoid jawline definition. A defined jaw in the 125-135° range is highly attractive in women — it signals health and youth. The key is staying within the gender-appropriate range rather than chasing the sharpest possible angle.
If your measured angle is above 135°, there is significant room for natural improvement. The three most effective methods, based on our data:
1. Reduce body fat below 15%
Removes facial fat that obscures the jawline. Expected improvement: 4-7° apparent angle reduction. See our complete jawline guide.
2. Masseter training with mastic gum
Builds jaw muscle width at the angle. Expected improvement: 2-4° apparent reduction in 4-8 weeks.
3. Fix forward head posture
Changes how the jaw angle reads from the front. Expected improvement: 3-5° apparent reduction in 2-4 weeks.
Combined, these three methods can shift your apparent jawline angle by 5-7 degrees over 8-12 weeks. That is enough to move from the "average" range into the "ideal" range for most people.
Our AI measures your exact gonial angle and tells you how you compare to 12,847 other faces.
💪 Test My Jawline →For men, 120-130 degrees. For women, 125-135 degrees. These ranges correlate with the highest attractiveness scores in our dataset of 12,847 faces. Going sharper than 115° actually reduces attractiveness.
The gonial angle is measured at the junction of the vertical and horizontal parts of the jaw. Our AI jawline test does this automatically from a front-facing photo — no manual measurement needed.
Yes. Body fat reduction, mastic gum chewing, and posture correction can improve apparent angle by 5-7 degrees over 8-12 weeks. This is enough to move most people from average into the ideal range.
Male models typically measure 115-128 degrees. Female models average 120-132 degrees. The sharpest angles in our dataset actually scored lower — there is a sweet spot.
