WHAT YOU RECEIVE
Your free jawline rating and supporting readings
The free result shows the jaw-balance dimension and five supporting readings. It focuses on selected front-view relationships, with separate values for contour alignment and the lower visible band.
Two jaw-pair differences
Inspect reflected jaw-contour and lower-jaw differences as a percentage of cheek width.
Lower-face and pose context
See the lower visible band and head-roll reading, with five open photo measurements in total.
Interpret jawline photos and compare styling choices
For a useful comparison, keep the visible outline and camera conditions consistent. Then compare the presentation choice you prefer rather than maximizing a width ratio.
Keep pose and expression consistent
Raising the chin, turning toward the light or opening the mouth can change the apparent outline. Use an eye-level camera, relaxed lips and even light. A photograph with a more dramatic shadow may look sharper without supporting a meaningful change in measured width.
A beard can frame and obscure the same contour
Facial hair can change the visible silhouette and cover the skin edge used by the detector. If the points follow hair instead of the visible jaw region, treat the ratio cautiously. Styling comparisons can be useful, but this scan cannot infer the hidden bone contour beneath a beard.
Use the result for a visible, reversible comparison
Compare a neckline, hair volume or facial-hair frame you prefer under matched capture conditions. The free result already includes the jaw-specific readings; buying the wider report does not reveal a hidden profile measurement. Whole-face paired alignment is available in the symmetry tool.

Jawline measurements: a front view is different from a profile
Read the quantity the photograph can support. More precise-sounding language does not add depth or physical units to a front-facing image.
| Question | Available here | What is outside this result |
|---|---|---|
| How wide does the jaw appear? | Jaw-anchor width relative to cheek width. | Bone width in millimetres. |
| How do the sides align? | Two reflected jaw-contour pair differences. | The cause of a visible difference. |
| How tall is the mapped lower region? | Lower visible band as a share of mapped height. | An anatomical lower-third diagnosis. |
| What is my gonial angle? | No true profile-angle measurement. | The ramus/body relationship requires a different view and method. |
What can a jawline rating measure from a front photo?
This jawline rating summarizes a selected front-view width relationship. Supporting contour and height readings help you inspect the image rather than treating one number as a complete anatomical assessment.
How the jaw span relates to cheek width
The jaw/cheek ratio compares the distance between selected jaw contour points with the visible cheek span. A value of 0.80 means the jaw span is four fifths of that cheek span. It describes frontal width, not whether the jaw is sharp, strong or healthy.
Whether selected left and right points align
Two pair readings compare reflected jaw-contour and lower-jaw coordinates across the fitted axis. Their values are normalized to cheek width. They help locate a visible difference but do not reveal whether it comes from structure, expression, head turn or a hidden contour.
The lower visible band supplies context
The lower band runs from a selected nose-area landmark toward the chin along the roll-corrected vertical span. It is a share of the visible landmark interval, not a measurement of ramus length, a true hairline-based lower third or an anatomical diagnosis.
Read how the visible face bands are defined ↗How the jawline balance score is calculated
The jaw-balance dimension uses one width ratio and a declared band. It is separate from the whole-face score and from the paired contour differences shown alongside it.
The same score used in the complete report
This page reuses the Jaw balance dimension from geometry-v1.1. It does not create a second jaw scoring engine. That dimension uses jaw/cheek width with a product reference band of 0.67–0.95 and a midpoint of 0.81. These constants are explicit product choices, not validated universal ideals.
The midpoint and edges have defined values
Inside the reference band, the score is 100 minus 18 times the squared distance from the midpoint, normalized by the half-band width of 0.14. It is rounded to a whole number. The midpoint returns 100; either edge returns 82. Wider is therefore not automatically higher-rated.
Outside the band and separate alignment readings
Beyond either edge, the score falls from 82 by 100 points for every additional 0.38 ratio units, clipped to 0–100. The paired jaw differences and lower band are shown separately and do not change this jaw-balance dimension. The overall face score uses additional dimensions.

FROM PHOTO TO REPORT
Use a front view with both jaw sides visible, read the width relationship and inspect the supporting contours. Keep a profile-angle question separate.
- 01
Show the chin and both jaw edges
Choose a clear adult front portrait with a relaxed mouth, camera at eye level and the chin fully in frame. Strong beard coverage or deep side shadows can hide contour points. Confirm photo permission first.
- 02
Check width before interpreting the score
Read jaw/cheek width and select it to inspect both spans. The jaw-balance score comes from that ratio and the declared product reference function. It is not a separate visual AI judgment of jawline quality.
- 03
Explore alignment and lower-face proportion
Open the two jaw-pair differences and lower visible band. Compare an upright matched photo if one side appears different. A frontal result does not reveal the side-profile gonial angle or chin projection.
Use a jawline rating for a clear front-view comparison
A USEFUL NEXT STEP
A score is easier to interpret when you know whether you are exploring width, alignment or photo presentation. Pick one question before retaking the image.
Compare the lower outline
Use an eye-level portrait with the chin and both jaw sides visible. Check whether hair, a beard or shadow changes which contour the detector follows. The measured surface is what is visible in this image.
Compare grooming or a neckline
Keep distance and posture fixed while trying a reversible framing choice. Judge the whole portrait rather than pushing the jaw/cheek ratio upward; a wider ratio does not always receive a higher score in this formula.
Keep a profile question separate
If you want to understand a side-profile angle, a front-view ratio cannot answer it. Do not use this rating to choose a procedure, infer anatomical structure or predict a physical change from a grooming exercise.
Jawline research: why an “ideal jaw” needs a defined study
Published preference studies use specific images, viewpoints and observer samples. They cannot silently become universal targets for every jawline calculator.
A preference study can have a very narrow stimulus set
Moradinejad and colleagues used manipulated images of one woman, rated by 127 observers, to study jawline preferences. Results from that design do not establish a universal ideal ratio or validate FaceRater’s jaw-balance reference band.
Our midpoint is a product assumption
The current jaw/cheek reference band is 0.67–0.95. Its midpoint is 0.81; the dimension decreases with distance from that midpoint. The number is a declared comparison choice, not a clinical threshold or an observer-population average.
Check width and alignment separately
A broad jaw can be paired with a visible left/right difference; a narrower jaw can appear closely aligned. This tool keeps the width ratio and pair readings separate, allowing you to see which relationship you are actually discussing.

Jawline analysis is different from a gonial angle test
A front portrait does not contain the same information as a standardized profile view. The tool states this boundary before a more precise-sounding angle could be inferred.
A frontal contour does not expose a profile angle
A side-view gonial angle depends on the direction of the mandibular body and ramus in profile. Connecting three points on a frontal photograph would create a different projected angle. This tool does not label that substitute as your actual gonial angle.
Chin projection and ramus length are not scored
A front portrait cannot establish how far the chin projects in profile or measure a hidden three-dimensional jaw length. There is no calibrated physical scale here, so the tool also does not output jaw dimensions in millimetres. The visible readings keep their actual ratio, percentage and angle units.
Outline classification answers a neighboring question
A broad frontal jaw can contribute to a square outline label, but an outline label is not a profile assessment. The face-shape page combines ordered width and length rules. Use that page when your goal is choosing a visual frame rather than inspecting jaw-specific spans.

Jawline rating questions, answered
These answers cover the jawline rating questions that affect how you use and interpret the result. Open a question for its measurement definition or a practical next step.
Can you rate my jawline for free?
+
Yes. The result includes the existing jaw-balance score, width ratio, two jaw-pair differences, lower visible band and head-roll context. You can inspect all five readings on your photo without buying a report.
What is a good jawline rating?
+
A higher score here means closer to the declared product reference around a jaw/cheek ratio of 0.81. It is not an established attractiveness standard. Read the ratio and capture conditions rather than treating a score as a universal verdict.
Can the tool measure my gonial angle?
+
No. This version uses a front portrait and does not claim a true side-profile gonial angle. A separate supported profile workflow would be needed for a properly defined profile measurement.
Does a wider jaw always get a higher score?
+
No. The current score is highest near its selected midpoint and declines in either direction. The declared function is shown on this page so you can understand the product choice.
Can jawline analysis tell bone structure from body fat?
+
No. A visible frontal contour cannot establish bone geometry or body composition. Lighting, expression, pose and facial hair can affect its appearance and detection.
What does paying add to the jawline result?
+
The optional $17.49 full report adds the rest of the geometry readings, regional explanations, a styling plan and PDF. It does not add a hidden gonial-angle model.
