Diamond Face Shape — AI Score & Traits Explained (2026)
High, prominent cheekbones are the widest point — narrower forehead and a tapered, often pointed chin create a four-corner silhouette that reads as sculpted on camera.
Last updated 2026-05-03 · 4 min read
Diamond is the shape casting directors and editorial photographers tend to chase, because the cheekbone-as-widest-point geometry creates depth under directional light that other shapes have to fake with contouring. Our metric distribution shows diamond faces clustering at the top of cheekbone protrusion and midface ratio — but they are unusually sensitive to camera height. A shot taken from below the chin can flip a strong diamond score into a "too-sharp" read.
What defines a diamond face shape
Geometric traits that distinguish diamond from the other five shapes. These are the markers our AI uses to classify your face.
- ✓Cheekbones are the widest part of the face — wider than both the forehead and the jaw.
- ✓Forehead is narrower than cheekbone width — this is the trait that most clearly distinguishes diamond from heart-shaped.
- ✓Chin tapers to a point or near-point rather than rounding off.
- ✓Face length is moderate — usually slightly longer than wide but not dramatically so.
- ✓Cheekbone protrusion (lateral) tends to be high — the silhouette reads as "high-cheekbone" rather than "round-faced".
Not sure if you're diamond? Walk the tree
Three yes/no questions, no ruler needed. Look in a mirror with hair pulled back and a neutral expression, then follow the branches. The leaf you land on is your closest shape match.
Length vs width
Is your face length clearly more than 1.5× your face width?
Eyeball check: if your face looks distinctly long and narrow, answer yes.
Yes → long face
Continue to Q2. You’re heading for Oblong or Oval.
No → compact face
Skip to Q3. You’re heading for Round, Square, Heart, or Diamond.
Long-face branch
Are your forehead and jaw roughly the same width (parallel sides)?
Yes → parallel sides
Oblong
Long, straight-sided face with forehead, cheek, and jaw within a few mm of each other. Minimal taper.
Open Oblong page →No → cheekbones widest
Oval
Long face with the cheekbones as the widest point and gentle tapering at forehead and chin.
Open Oval page →Compact-face branch
Where is your face widest — forehead, cheekbones, or all roughly equal?
Forehead widest
Heart
Wide forehead tapers to a narrow, pointed chin. Confirm with the cheek-tilt test.
Open Heart →Cheekbones widest
Diamond
Cheek clearly wider than both forehead and jaw — narrow at both ends, double taper.
Open Diamond →All equal · angular jaw
Square
Forehead, cheek, and jaw similar width with a strong, angular jawline and visible corners.
Open Square →All equal · soft jaw
Round
Similar widths but no hard angles — full cheeks and a soft, rounded chin and hairline.
Open Round →Borderline answers? The AI face-shape test on /face-shape-test uses 68-landmark measurement and resolves cases the eye-only tree can’t.
Where diamond faces photograph best
- →Editorial and fashion photography — the high cheekbones and tapered chin photograph as sculpted under directional lighting.
- →Profile and three-quarter shots — diamond shapes often look strongest in side-lit angles that emphasize cheekbone protrusion.
- →Hairstyles with width at the temples — softens the diamond geometry into a more oval read.
How diamond faces score on our 17 metrics
Our scoring engine measures 17 facial-geometry markers. Some metrics correlate strongly with face shape — here's what diamond faces typically score on the metrics where the overlap is most pronounced.
Cheekbone Protrusion
↑ HigherBy definition the diamond shape has the cheekbones as the widest point — this metric scores at the top of the distribution for this shape.
Midface Ratio
↑ HigherHigh cheek-width over narrow jaw-width pushes midface ratio above the population mean.
FWHR
↓ LowerDiamond shapes tend to be longer than wide — FWHR scores trend lower than square or round shapes, which can read as higher trustworthiness in research literature.
Jawline Definition
↑ HigherThe taper toward a pointed chin creates a defined gonial line that scores well on jawline definition.

What each score band means for diamond faces
Our audit returns a 0–100 score broken into four bands. Score bands mean different things depending on shape — here's what each tier typically reflects when the face is diamond.
Top-band diamond faces compound on the metrics our scoring engine weighs most heavily — high cheekbones and a defined jaw both load positively. Improvement plans here focus on photo selection rather than feature-level changes.
High-band diamond faces often have a "soft fail" on one trait — usually the forehead reading as too narrow under flat lighting, or the chin reading as too sharp on a low-angle shot.
Mid-band diamond scores often reflect photo angle more than geometry — diamond shapes are unusually sensitive to camera height. A photo retake at chin-height typically moves the score notably.
Low-band diamond scores are usually lighting-driven — the high cheekbones cast shadows under harsh overhead light that the engine reads as gauntness. Soft, slightly elevated lighting fixes this.
