Method

How it works and the exact formula

Face shape is one of the most searched beauty questions because it drives almost every styling decision: haircut, glasses, necklines, even earrings. The usual advice is to trace your reflection on a mirror with lipstick, which is subjective and easily thrown off by hair, lighting and how far you stand from the glass. This detector replaces guesswork with three measured ratios.

MediaPipe Face Landmarker places 478 landmarks on your face in the browser. After converting to pixel space and levelling your head on the line between your irises, we measure face length (upper forehead to chin), cheekbone width, forehead width and jaw width. Every width is divided by cheekbone width, which makes the result independent of how large your face appears in the photo.

The classifier is a rule-plus-vector model. Each of the six shapes (oval, round, square, heart, diamond and oblong) has a prototype vector of the three ratios, computed as the average of reference faces of that shape. Your ratios are compared with every prototype using a weighted distance, converted into probabilities with a softmax, and nudged by a few unambiguous rules: a length-to-width ratio of 1.55 or more favors oblong, a jaw nearly as wide as the cheekbones with a sharper angle favors square, and a forehead far wider than the jaw favors heart.

Because most people sit between two prototypes, you see a probability for each shape rather than a single label. A result like 52% oval and 31% heart tells you to start with oval advice but borrow the heart-shape tricks for balancing a narrower chin. If two shapes are within 10 points, treat yourself as a blend and use the try-on to decide.

For an accurate result, pull your hair back so the forehead edges are visible, keep your chin level and hold the camera at eye level from arm's length. A fringe hides landmarks 103 and 332, which pushes results toward diamond, and a raised chin shortens the face, which pushes results toward round.

Formulas

Length-to-width: LWR = |L10 − L152| ÷ |L234 − L454|
Forehead-to-cheek: F2C = |L103 − L332| ÷ |L234 − L454|
Jaw-to-cheek: J2C = |L58 − L288| ÷ |L234 − L454|
Shape probability: p(shape) = softmax(−½ · Σ wᵢ · ((ratioᵢ − prototypeᵢ) ÷ scaleᵢ)² + rule prior)

MediaPipe landmarks used

Anatomical point	Index	Role
Iris centers	468 / 473	Level the face so widths are measured on a true horizontal.
Trichion (proxy) / menton	10 / 152	Face length.
Zygion	234 / 454	Cheekbone width: the reference width for every ratio.
Forehead edges	103 / 332	Forehead width (heart vs. diamond).
Gonion (proxy)	58 / 288	Jaw width (square vs. tapered).

Benchmarks

Face-shape prototypes used by the classifier

Face-shape prototypes used by the classifier
Face shape	Length ÷ width	Forehead ÷ cheek	Jaw ÷ cheek	Signature
Oval	≈ 1.48	≈ 0.83	≈ 0.79	Balanced length, gently tapered jaw
Round	≤ 1.30	≈ 0.84	≈ 0.83	Length close to width, soft jaw
Square	≈ 1.39	≈ 0.85	≥ 0.87	Wide jaw with a sharper angle
Heart	≈ 1.41	≈ 0.86	≤ 0.72	Forehead clearly wider than jaw
Diamond	≈ 1.44	≤ 0.80	≤ 0.77	Cheekbones are the widest point
Oblong	≥ 1.55	≈ 0.82	≈ 0.76	Noticeably long with straight sides

Prototype values are the centroids of the reference set used for celebrity matching, so the classifier and the bone-structure match share one metric space. Rule thresholds (≤ 1.30, ≥ 1.55, ≥ 0.87) add small priors for clear-cut cases.

Styling

Styling and virtual try-on by result

Once you know your shape, the rule is simple: add what your proportions lack and soften what dominates. Each link opens the matching try-on.

Oval

Almost every cut and frame works. Show off balance with a middle part, sleek lob or classic side part; most necklines suit you, so choose by color season.

Try 6 cuts on your photo

Round

Add length and angles: height at the crown, long layers starting below the chin, deep side parts, rectangular frames and V-necklines.

See angular frames

Square

Soften the jaw with waves, layers that fall past it, round or oval frames, and scoop, cowl or sweetheart necklines.

Preview softening necklines

Heart

Add width at the chin: chin-length bobs, curtain bangs, bottom-heavy frames and boat or square necklines.

Try chin-length cuts

Diamond

Widen the forehead and chin around strong cheekbones: side-swept fringes, browline or oval frames, sweetheart necklines.

Find browline frames

Oblong

Add width and shorten length: fringes, side volume, waves, wide frames and horizontal necklines such as boat and square.

Face Shape Detector: frequently asked questions

What is my face shape?

Upload a front-facing selfie with your hair pulled back and the detector measures your length-to-width, forehead-to-cheek and jaw-to-cheek ratios, then shows the probability of each of the six shapes. Most people get a clear first choice and a secondary shape.

How do I know if my face is oval or round?

Length is the difference. Oval faces are about 1.4–1.5 times longer than they are wide, measured from the upper forehead; round faces are 1.3 or less and have a softer jaw. The detector shows both probabilities so you can see how close you are.

Can you have two face shapes?

Yes. Faces are continuous, and many sit between two prototypes, for example oval-heart or square-round. That's why we show a probability for every shape instead of forcing a single label.

Is the most common face shape oval?

Oval and round are the most frequently reported shapes in styling literature, but there's no reliable population census of face shapes. In practice, many people classify as oval because it sits in the middle of the ratio space.

Why does my face shape change between photos?

Lens distance and head angle change measured widths. Close phone cameras narrow the jaw and enlarge the center of the face; tilting your chin down shortens the face. Use a straight-on photo at arm's length with hair off your forehead.

What is the most attractive face shape?

No single shape is most attractive. Oval is often called 'ideal' only because almost every style suits it. Harmony between features matters more than outline, which is what the attractiveness test measures.

How accurate is a face shape detector compared with a stylist?

The ratios are measured more consistently than by eye, but the shape labels are conventions, not anatomy. A stylist also considers hair texture, neck length and lifestyle, which is why the try-on shows you the cuts rather than just naming them.
