"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 peer-reviewed reference data measured faces tell us about the ideal gonial angle.
How does your jaw shape score?
Upload a photo — the analysis reads your jaw shape from 68 landmarks as jaw taper and chin proportion. The gonial angle itself needs a side-profile photo.
Key finding
The ideal gonial angle is 120-130° for men and 125-135° for women. "Sharper is always better" is a myth: below about 115° a jaw starts to read harsh rather than defined. The sweet spot balances definition with facial harmony.
What is the gonial angle?
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 detects the mandibular landmarks from a front-facing photo, but deliberately does NOT print a gonial angle from them: the front-vs-lateral limit means a front photo cannot measure this honestly, so the report names it as needing a profile shot rather than guessing a number. The jawline test shows where your front-view jaw reading sits among the people who have scanned here; the full report scores jaw shape itself as jaw taper and chin proportion. Jawline Angle is one of the 17 measurements the engine calculates — all 17 measurements are explained honestly here, including which ones respond to effort and which are fixed bone structure.

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.
Why the "ideal" differs by gender
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.
How to improve your jawline angle
If your measured angle is above 135°, there is significant room for natural improvement. The three most effective methods:
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. Users tracking measurable progress often pair the angle reading with a wider facial geometry assessment with PDF, which may help understand whether jawline gains are translating into changes in adjacent proportions.

What is the ideal jawline angle?
For men, 120-130 degrees. For women, 125-135 degrees. These ranges align with published orthodontic and anthropometric reference standards (Proffit, 2018; Arnett & Gunson, 2004). Going sharper than 115° actually reduces attractiveness.
How do you measure jawline angle?
The gonial angle is measured at the junction of the mandibular ramus (vertical part of the jaw) and the mandibular body (horizontal part), normally on a side-profile X-ray or photo. A front-facing photo cannot measure it, so our free AI jawline test reads your jaw outline from a front photo and returns a front-view band rather than a gonial angle.
Can you improve your jawline angle?
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.
What jawline angle do models have?
Male models typically measure 115-128 degrees. Female models average 120-132 degrees. The sharpest angles (below 115°) read as overly angular and score lower in perception studies (Naini, 2011) — there is a sweet spot.
