Reference

The Six Face Shapes

Every face is a blend, but nearly all of them lean toward one of six classic shapes. Here's what defines each one — the signature proportions, how to tell it apart from its neighbors, and the styling direction that flatters it.

Square

A strong, angular jawline with forehead, cheekbone and jaw widths all similar. Soft, rounded styles offset the angles.

Signature proportions: Length is close to width, and forehead, cheekbones and jaw all measure nearly the same.
How to tell it apart: A strong, angular jawline with a defined corner at the jaw angle, plus a squared hairline, are the giveaways.

Round

Length and width are close to equal, with soft curved lines and full cheeks. Angles and vertical volume add definition.

Signature proportions: Length is close to cheekbone width (around 1.1–1.18×) with soft, curved sides and full cheeks.
How to tell it apart: A rounded hairline and rounded chin. The face reads almost as wide as it is long, with no sharp angles anywhere.

Heart

A wide forehead and cheekbones that taper to a narrow, pointed chin. Volume around the jawline balances the taper.

Signature proportions: The forehead is the widest zone (roughly 75–80% of cheekbone-to-length proportion), and the jaw tapers to a pointed chin.
How to tell it apart: High, wide cheekbones over a noticeably narrower chin — the outline resembles an upside-down triangle.

Oval

Slightly longer than it is wide, with balanced proportions and a softly rounded jaw. The most versatile shape — most styles work.

Signature proportions: Face length is roughly 1.2–1.25× cheekbone width; the forehead and jaw taper gently and stay close in width.
How to tell it apart: No single feature dominates. Cheekbones are slightly wider than the forehead, but the jawline stays rounded — never square.

Diamond

Prominent cheekbones dominate, with a narrower forehead and jaw. Fringe and collar detail add width at the top and bottom.

Signature proportions: Cheekbones are the widest point of the face; forehead and jaw both measure clearly narrower.
How to tell it apart: Narrow forehead and temples with a pointed chin — often the narrowest forehead of all six shapes.

Oblong

Noticeably longer than it is wide, often with a high forehead. Side volume and horizontal lines visually shorten the face.

Signature proportions: Length clearly exceeds width (1.28× or more) while forehead, cheekbones and jaw stay similar in width.
How to tell it apart: An elongated midface and relatively straight sides; the face looks stretched vertically rather than wide.

At a Glance

Face Shape Comparison Chart

The three ratios below are the same ones the detector computes. Ranges are typical reference values — real faces drift outside them, which is why the result also shows a full shape breakdown.

Shape	Length / width	Forehead / cheekbone	Jaw / cheekbone	Quick cue
Oval	1.18–1.25	≈0.76	≈0.80–0.85	Smooth, gently tapered outline; jaw slightly narrower than cheekbones
Round	1.10–1.18	≈0.73	≈0.80–0.83	Full cheeks and soft curves; length barely exceeds width
Square	1.10–1.20	≈0.73–0.75	≥0.85	Forehead, cheeks and jaw nearly equal; angular jaw corner
Heart	1.15–1.22	≥0.77	≤0.78	Widest forehead of the six; jaw tapers to a pointed chin
Diamond	1.12–1.20	≤0.72	≈0.78–0.82	Cheekbones widest; both forehead and jaw narrow
Oblong	≥1.28	≈0.75	≈0.80	Clearly longer than wide; straight sides, similar zone widths

DIY Method

How to Measure Your Face Shape Manually

Prefer a tape measure? Stand in front of a mirror at eye level and take these four measurements, then divide as described in the comparison chart above. A flexible sewing tape works best; a phone photo with a straight-on angle also works — that's exactly what the detector does for you.

01Face length

Measure from the center of your hairline straight down to the tip of your chin. If a fringe covers your hairline, start at the point where your forehead becomes visible.

02Forehead width

Measure across the widest part of your forehead, roughly halfway between your eyebrows and your hairline, from one side of the forehead curve to the other.

03Cheekbone width

Measure across the top of your cheeks, just below the eyes, from the outermost point of one cheekbone to the other. This is usually the widest measurement.

04Jaw width

Measure from just below one ear, where the jaw angles upward, down to the center of your chin — then double it. Keep the tape at the jaw's widest sweep.

Then compute two ratios: face length divided by cheekbone width, and forehead width divided by cheekbone width. A ratio above roughly 1.28 leans Oblong; a forehead-to-cheekbone ratio of 0.77 or more with a narrow jaw leans Heart. Everything in between is where Oval, Round, Square and Diamond live — and where the detector's six-way comparison is genuinely faster than a tape.

Styling

The Style Playbook for Every Face Shape

Hairstyles, necklines, glasses and accessories all obey the same principle: add width where the face is narrow, soften it where it's angular. Expand your shape below for the full playbook.

Styling a square face shape

Hairstyles

·Side-swept fringes and textured layers round off sharp corners.
·Styles that add height on top stretch the face vertically.
·Avoid blunt, straight-across bobs that echo a heavy jaw.

Necklines & Collars

·Round, scoop and V-necks soften angular lines.
·Open collars with a soft roll look more relaxed than stiff points.
·Skip square and boat necks — they mirror the jawline.

Glasses

·Round, oval and aviator frames counterbalance angular features.
·Thin metal rims keep the look light.
·Avoid sharp square or rectangular frames.

Accessories

·Hoop or drop earrings add curves near the jaw.
·Rounded watches and soft-knotted scarves over structured ties.

Styling a round face shape

Hairstyles

·Volume on top — quiffs, pompadours, long layers below the chin — elongates the face.
·Side parts break up circular symmetry.
·Avoid chin-length bobs and full volume at the cheeks.

Necklines & Collars

·V-necks and long open plackets draw the eye vertically.
·Structured collars add angles to soft features.
·Avoid chokers and tight high necks that shorten the face.

Glasses

·Rectangular and wayfarer frames add definition.
·Angular browlines lift the face.
·Avoid perfectly round frames that echo the shape.

Accessories

·Long pendant necklaces and vertical scarf lines stretch the look.
·Angular, geometric earrings over round studs.

Styling a heart face shape

Hairstyles

·Chin-length bobs and jaw-level waves add width where the face narrows.
·Side-swept fringes soften a broad forehead.
·Avoid slicked-back styles that expose the full forehead.

Necklines & Collars

·Soft V-necks and scoop necks follow the taper instead of fighting it.
·Spread-collar shirts balance a wider brow.
·Avoid wide, square collars that repeat the forehead line.

Glasses

·Bottom-heavy and aviator frames add width to the lower face.
·Rimless styles keep the forehead area light.
·Avoid bold, decorative top rims.

Accessories

·Teardrop and chandelier earrings fill out a narrow chin.
·Medium-brim hats sit comfortably over a broader forehead.

Styling a oval face shape

Hairstyles

·Almost everything works — layers, bobs, slick-backs, crops.
·Keep proportions balanced; avoid overly heavy fringes hiding the symmetry.
·Experiment: this shape tolerates trends well.

Necklines & Collars

·Every neckline works — crew, V, boat, turtleneck.
·Choose collars for the outfit, not for face correction.
·Statement collars are safe territory.

Glasses

·Most frame shapes suit — wayfarer, oval, rectangle, aviator.
·Pick frames by personal style and coloring.
·Match frame width to face width for the cleanest fit.

Accessories

·Minimal rules — statement pieces land well on balanced proportions.
·Both round and angular jewelry complements.

Styling a diamond face shape

Hairstyles

·Fringes cover a narrower forehead and shorten the cheek line.
·Volume at the crown and jaw balances prominent cheeks.
·Avoid tight, slicked styles that expose the hairline taper.

Necklines & Collars

·Boat necks and off-shoulder cuts widen the shoulder line.
·Detailed collars draw attention away from the cheekbones.
·Avoid deep V-necks that narrow the face further.

Glasses

·Browline frames widen the upper face.
·Oval and rimless styles soften sharp cheekbones.
·Avoid narrow rectangles that repeat the taper.

Accessories

·Statement earrings celebrate the cheekbones — they are an asset.
·Wide scarves and collars balance the lower face.

Styling a oblong face shape

Hairstyles

·Fringes and side parts visually shorten a long face.
·Build volume at the sides, not on top.
·Avoid long, straight styles and tall pompadours.

Necklines & Collars

·Crew necks, boat necks and wide collars add horizontal width.
·Horizontal stripes and layered scarves work well.
·Avoid deep V-necks and long open plackets.

Glasses

·Tall, oversized frames (big squares, aviators) add depth to the face.
·Wide frames bridge more of the cheek line.
·Avoid small, narrow rectangles.

Accessories

·Short, wide necklaces and wrapped scarves keep lines horizontal.
·Wide-brim hats compress height and widen the silhouette.

Accuracy

How Accurate Is an AI Face Shape Detector?

The detector maps 478 facial landmarks with a face mesh model and converts them into four ratios, so the measurements themselves are precise and repeatable: the same photo always produces the same numbers, on any device.

Real-world accuracy depends on the photo, not the model. Three things cause most misreads: a fringe that hides the hairline (shortens face length), a full beard that widens the jaw outline, and camera angles that flatter one side of the face. A straight-on photo solves all three at once.

Also remember that the six shapes are categories drawn over a continuum. Plenty of people sit between two shapes — the shape breakdown in your result is there precisely so a boundary case is visible instead of hidden.

Privacy

Your Photo Never Leaves Your Device

The face shape detector runs on-device. The AI model is downloaded to your browser once, and every detection — landmark mapping, measurement, classification — happens on your own hardware.

No photo is uploaded, stored or sent to any server, and there is no analytics on image content — the page has no way of seeing what you uploaded. Close the tab and the photo is gone from memory.

This is the same privacy model as the PSL rating calculator on our home page: the analysis is free, anonymous and account-free.

By Audience

Face Shapes in Men vs Women

The six shapes and the measuring method are identical for everyone — bone structure doesn't have a gender. What differs is the distribution. On average, male faces show wider and more angular jaws relative to the cheekbones, so Square and Oblong readings are somewhat more common, while female faces more often land in the Oval and Heart ranges with a tapering lower third.

Styling norms then amplify the difference. Beards add visible width to the jaw and chin — a beard can make an Oval face read Square, or soften a very angular jaw the other way. For men who want the detector to see bone structure rather than styling, a short, trimmed beard is the most neutral state. Long hair swept forward can narrow the apparent forehead for anyone, which is why the photo tips ask for the hairline to stay visible.

Whatever your gender, treat the result as a description of proportions, not a rulebook. The styling playbook works the same way for all six shapes: balance width against length and echo or soften the jawline depending on the look you want.

In Photos

Which Face Shape Is the Most Photogenic?

None of them, intrinsically — camera favoritism is mostly a lighting and angle story. Classical art favored balanced Oval proportions, and that bias lingers in style writing, but every shape has faces that photograph beautifully because the photographer found the right angle for the bone structure.

Practical shortcuts per shape: Oval suits nearly any angle; Heart faces shine front-on where the wide forehead frames the eyes; Square and Diamond faces gain the most from a three-quarter turn, which softens the jaw corner and cheekbone width; Round and Oblong faces benefit from a slight chin forward-and-down tilt to lengthen or shorten the midface respectively. Diffused frontal light flatters rounder faces; side light adds definition to angular ones.

FAQ

Frequently Asked Questions

How does a face shape detector work?

It plots dozens of facial landmarks on your photo and reduces them to a few proportions: face length versus cheekbone width, forehead width versus cheekbone width, jaw width versus cheekbone width, and chin width versus cheekbone width. Those ratios are compared against the six classic face shapes — Square, Round, Heart, Oval, Diamond and Oblong — and the closest statistical match wins.

Which face shape is most common?

Oval is generally considered the most common face shape, which is why most hairstyles and glasses are designed around it. That said, most faces are a blend of two shapes — the shape breakdown in your result shows how close you sit to each one.

Can my face shape change over time?

Your bone structure stays the same, but weight changes, muscle tone, hairstyle and aging can shift how wide or long your face reads. If your face changes noticeably, run the detector again — it takes seconds and the same photo will always score the same way.

Is my photo uploaded anywhere?

No. The face shape detector runs entirely in your browser using on-device AI. Your photo is never uploaded, stored or sent to any server — once you close the page, it's gone.

What kind of photo works best?

A front-facing photo with your eyes level, even lighting, and hair away from your forehead and temples. Glasses, heavy shadows and extreme camera angles can skew the measurement of your forehead and jaw.

Does my hairstyle affect the result?

It can. A heavy fringe that covers the forehead makes the face-length measurement read shorter than it really is, which can push results toward Round. If you can, tie your hair back before taking the photo so the hairline is visible.

Does a beard change my face shape?

Visually, yes — a full beard adds width along the jaw and chin, which can make an Oval or Oblong face read more Square. The detector measures the outline it can see, so for the most accurate reading of your bone structure, a short or freshly trimmed beard works best.

Can I use a group photo?

No — the detector works on photos containing exactly one face. If more than one face is found, it stops and asks for a solo photo rather than guessing which face you mean.

Why did I get a different shape than an online quiz told me?

Most quizzes ask you to self-describe features ('Is your jaw angular?'), which is subjective. A face shape detector measures actual pixel distances and compares ratios, so it's more consistent — though faces near a boundary between two shapes can legitimately sit on either side.

Why is my confidence below 60%?

A lower match usually means your proportions blend two shapes. That's common and not an error — read the shape breakdown to see the runner-up, and use the styling advice for whichever description fits you best in the mirror.

How long does detection take?

Usually a few seconds, depending on your device. The AI model loads once in your browser and then runs on your own hardware — there is no network round-trip, which is also why it works offline after the first load.

Do I need an account to use the face shape detector?

No. Detection is completely free and anonymous. An account is only needed if you want to save results from the full PSL rating calculator on the home page.

What's the difference between face shape and a PSL rating?

Face shape is a category — which of six proportion families your measurements fall into. A PSL rating is a graded attractiveness score across symmetry, proportions and features. Think of face shape as the map and PSL as the terrain analysis; the two work well together.

I know my face shape — how do I get a full PSL rating?

Face shape is just the first step. A full PSL rating scores your symmetry, proportions and features on the classic scale and turns them into a prioritized improvement plan. Run the free PSL rating calculator on our home page: upload a photo and it measures 15 facial metrics in about a minute. Start with the face shape detector here, then continue to the full facial analysis when you're ready.

Is the detector suitable for children?

The tool is designed for adult faces. Children's facial proportions are still developing — the lower face in particular grows for years — so a result for a child should be treated as a snapshot, not a fixed classification.
