Method

How it works and the exact formula

A jawline rating needs more than one number. A jaw can be wide but soft, narrow but sharply angled, or strong because the whole face is broad. This test rates your jawline with three measurements from the same 478-landmark scan: how wide the jaw is relative to the cheekbones, how sharp the angle at the jaw corner is, and how broad the face is relative to its height.

The jaw-to-cheek ratio divides the distance between the two jaw corners (gonion proxies, landmarks 58 and 288) by bizygomatic width, the distance between the cheekbones (234 and 454). A ratio near 0.80 is balanced; higher values mean a squarer jaw, and lower values a tapered V-shape. This ratio drives the square, heart and diamond decisions in our face-shape classifier.

The jaw angle is measured at each jaw corner between two rays: one up toward the cheekbone, approximating the ramus, and one toward the chin (menton, 152), approximating the mandibular body. Left and right are averaged. On a true lateral cephalogram the gonial angle averages roughly 120–130° in adults; from a front photo our angle is a projected estimate, which is why it is labelled jaw angle rather than true gonial angle. Lower values read sharper and more defined.

Finally, facial width-to-height ratio (fWHR) divides cheekbone width by the distance from the brow center to the top of the upper lip. Typical adult values are 1.8 to 2.0. A higher fWHR makes the whole lower face read stronger and more dominant in first-impression research. All three numbers are computed after levelling your head on the iris line, entirely in your browser.

Formulas

Jaw-to-cheek: |L58 − L288| ÷ |L234 − L454| (balanced ≈ 0.80)
Jaw angle (per side): ∠(L234 − L58, L152 − L58) in degrees, averaged left and right
fWHR: |L234 − L454| ÷ |L168 − L0|
Scores: jaw: Gaussian(0.80, 0.09) · angle: Gaussian(125°, 14°) · fWHR: Gaussian(1.9, 0.18)

MediaPipe landmarks used

Anatomical point	Index	Role
Iris centers	468 / 473	Define the interpupillary line used to level the whole face before any ratio is computed.
Gonion (proxy)	58 / 288	Jaw corners: jaw width and the vertex of the jaw angle.
Zygion	234 / 454	Cheekbone width and the upper ray of the jaw angle.
Menton	152	Chin point: lower ray of the jaw angle and bottom of face length.
Chin edges	172 / 397	Chin width, used for the symmetry pair and chin shape.

Benchmarks

Jawline bands and how the scanner scores them

Jawline bands and how the scanner scores them
Metric	Band	Value range	Tool score	Modelled percentile
Jaw ÷ cheek	Square	0.87 – 0.95	25–74	3rd–78th
Jaw ÷ cheek	Balanced	0.75 – 0.85	86–100	93rd–99th
Jaw ÷ cheek	Tapered (V)	0.65 – 0.74	25–80	3rd–87th
Jaw angle	Sharp	105° – 115°	36–77	9th–83rd
Jaw angle	Defined	115° – 130°	77–100	83rd–99th
Jaw angle	Soft	135° – 150°	20–77	1st–83rd
fWHR	Broad	2.00 – 2.20	25–86	3rd–93rd
fWHR	Typical	1.80 – 2.00	86–100	93rd–99th

Front-photo jaw angles are projections; a side photo or cephalogram is needed for the true gonial angle. Percentiles are modelled from the reference distribution our scorer uses (scores are mapped through a normal curve, mean 60, SD 18), not from a database of user faces. We don't build one: selfies are deleted within 2 hours and free scan results after 48 hours.

Styling

Styling and virtual try-on by result

Hair, beards and necklines sit right next to the jaw, which makes the jawline the easiest feature to sharpen or soften with styling.

Square jaw (ratio 0.87+)

Show it off with short sides and texture on top, or soften it with waves and layers that fall below the jaw. Scoop and cowl necklines and round frames add curves against the angles.

See necklines for a square jaw

Tapered jaw (below 0.75)

Add width at jaw level: chin-length bobs, side-swept volume, a fuller beard at the sides. Boat, square and wide crew necklines echo width that the jaw lacks.

Try jaw-length cuts

Soft jaw angle (135°+)

Tight fades or sleek sides above the ear add contrast that makes the jaw corner read sharper. A short, well-edged beard line along the jaw creates definition; V-necks draw the eye down and lengthen.

Preview tapered sides

Very sharp angle (under 115°)

Your jaw already reads strong. Medium-length cuts with movement and rounder frames keep the face approachable; very boxy styles can look severe.

Find balancing frames

Low fWHR (under 1.8)

A longer, narrower face benefits from width: side volume, horizontal necklines and frames as wide as the cheekbones.

Jawline Rating Test: frequently asked questions

How do I know if I have a good jawline?

A well-defined jawline usually combines a jaw-to-cheek ratio between about 0.75 and 0.90, a jaw angle that is not too obtuse and low soft-tissue fullness under the jaw. The test measures the first two; body fat and posture affect the third.

What is a normal gonial angle?

On side-view X-rays the adult gonial angle averages roughly 120–130°, with lower angles reading sharper and more square. Our front-photo jaw angle is a projected estimate and runs on its own scale, so compare your result with the bands in the table rather than with radiographic values.

Can I measure my gonial angle from a selfie?

Only approximately. The true gonial angle is measured in profile between the ramus and the mandibular body. From the front we approximate both lines with landmarks, which is consistent for tracking but not equivalent to a cephalometric measurement. For a profile view, use the side profile analysis tool.

Does mewing change your jawline?

There is no good evidence that mewing changes adult bone structure. Lower body fat, posture and grooming (beard shaping, haircut) change how the jawline looks much more reliably.

What hairstyle makes your jaw look sharper?

Short or faded sides with volume on top increase the contrast between the side of the head and the jaw corner, which reads as sharper. For longer hair, layers that start below the jaw and a deep side part do the same.

Why does my jaw look wider in selfies?

Phones held close to the face exaggerate whatever is nearest the lens, usually the nose and midface, and compress the sides of the face. Some angles from below also widen the jaw. Take the scan photo at arm's length at eye level for an accurate ratio.

What is fWHR and why is it in a jawline test?

Facial width-to-height ratio compares cheekbone width with upper-face height. Together with jaw width it determines how strong the lower face reads. Higher fWHR has been associated with perceived dominance in research by Carré and McCormick.
