Face Shape Analyzer
Upload a photo and the outline of your face is traced automatically, then measured from the brow line down: temples, cheekbones, jaw and chin. See the widths on your own photo before anything is named.

Your photo stays on this device
The face model runs in your browser. Nothing is uploaded, nothing is stored, and closing the tab is all it takes to be rid of it.
For the truest reading: square-on to the camera, hair back off the forehead and jaw, no strong angle from below or above.
What is actually being measured
Face shape is not a fact about you the way your height is. It is a shorthand for five measurements and the ratios between them, and every published definition — “oval is about one and a half times as long as it is wide” — is a statement about those ratios. So this page measures them first and names them second.
Length
Brow line to the bottom of the chin
Temples
Width across the outline at the brows
Cheekbones
The widest point below the brows
Jaw
Width at about seven tenths of the way down
Chin
Width just above the point of the chin
Jaw corner
How sharply the outline turns toward the chin
The dashed line is the brow. The four widths use the same colours here as the lines drawn over your photo.
Only the ratios matter. The numbers on screen are pixels, and a photo taken a step closer changes every one of them while changing none of the ratios — which is the point.
Why the trace stops at your forehead
The face mesh has no hairline points. Hair is not a facial feature — it moves with a haircut, it recedes, and on a shaved head it is not there at all — so the model does not try to find it, and the top of the traced outline is a fixed point that lands somewhere in the middle of a real forehead.
Rather than invent an outline up to a hairline nothing detected, everything here is measured from the brow line down. The brow is a real feature, found as reliably as the eyes, so brow-to-chin means the same thing on every face. It also means your length ratio will read lower than the figures in style guides, which measure from the crown — compare your reading to the other six shapes on this page, not to a published number.
The seven shapes
Real faces sit between these far more often than on them, so the tool scores all seven and reports the gap to the runner-up. A four-point gap means the two descriptions fit about equally well, and both are worth reading.
Oval
Noticeably longer than it is wide, widest at the cheekbones, tapering gently to a rounded chin. It is the shape the other six are usually described against.
- · Clearly longer than it is wide
- · Forehead a little wider than the jaw
- · No hard corner anywhere on the outline
Round
About as long as it is wide, widest through the cheeks, with a soft outline and no visible jaw corner.
- · Length and width close to equal
- · Widest point at mid-face
- · Soft, continuous outline
Square
Forehead, cheekbones and jaw close to the same width, with a strong corner where the jaw turns toward the chin.
- · Three widths nearly equal
- · Sharp jaw corner
- · Length close to width
Rectangle
The square proportions stretched: three widths close to equal, but the face is markedly longer than it is wide. Also called oblong.
- · Three widths nearly equal
- · The longest of the seven for its width
- · Defined jaw
Heart
Widest at the forehead, narrowing through the cheekbones to a small, often pointed chin.
- · Forehead the widest measurement
- · Clear taper to the chin
- · Narrow chin relative to the jaw
Diamond
Cheekbones clearly the widest point, with both the forehead and the jaw narrower than them.
- · Cheekbones the widest measurement
- · Forehead narrower than the cheeks
- · Narrow jaw and chin
Triangle
Jaw the widest measurement, narrowing upward to a smaller forehead. Sometimes called pear.
- · Jaw wider than the cheekbones
- · Forehead the narrowest measurement
- · Weight low in the face
Why the outline is drawn on your photo
A shape name on its own cannot be checked. Told “heart”, most people nod; told “diamond”, most people nod at that too. A traced jaw that misses the jaw, on the other hand, is obvious in a second — so the trace is shown, along with the exact lines the four widths were read from.
The trace comes from a 478-point face mesh running in your browser. If the outline hugs your jaw and cheeks, the numbers under it mean something. If it wanders into your hair or cuts across your cheek, they do not, and no amount of confident naming fixes that. The one place it is meant to stop short is the top: it ends partway up the forehead, and nothing above the brow line is measured.
What makes a photo readable
- Square-on. A head turned even slightly reads narrower on one side, and the jaw ratio is the first thing to go.
- Hair back. The outline follows skin, not hair. Loose hair over the jaw is the one that matters, since the jaw and chin widths are three of the five ratios.
- Level with the face. Shot from below the jaw widens; from above the temples do.
- Tilt is fine. A head tilted in the frame is levelled before measuring, so that one you can ignore.
What the styling advice is, and is not
The frame, hair and neckline suggestions all come from one old rule: a shape reads as balanced when what you put near it contrasts with what it already does. Round frames soften a square jaw; a strong brow line fills a narrow forehead. That rule is convention, not evidence, and it is a starting point rather than a verdict.
Plenty of people look best in exactly what the rule says to skip. Treat it as a way to understand why something looked wrong on you last time, not as a list of things you are now allowed to wear.
Where the numbers come from
The mesh is Google’s MediaPipe Face Landmarker, and the outline is its own published face-oval contour rather than a hand-picked list of point numbers — a wrong assumption then shows up as a visibly wrong trace instead of a plausible number taken from the wrong place.
Before anything is measured the face is rotated so the eyes are level, because every width is read along the horizontal and a tilted head would otherwise measure wider and shorter than the same head held straight. Each width is then found by intersecting the outline with a horizontal line at a fixed fraction of the face length, so the same face gives the same ratios at any resolution.
Matching is a weighted distance across all five ratios rather than a chain of thresholds. A rule chain gives one answer with no sense of how close the call was; a distance gives every shape a score, and the gap between the top two is the honest measure of how firm the answer is.
The reference point for each shape was measured, not copied. Writing the published definitions in directly made the tool answer “round” or “heart” for almost everyone, because five of the seven targets sat at a length ratio this method never produces. Instead, nine outlines were drawn per shape — each one that shape by construction, varied in size, corner sharpness and taper — and pushed through the same measuring path the page uses; each shape’s reference point is the centre of its nine. Fed back in, those sixty-three outlines return their own shape 87% of the time, and every miss falls inside the oval, heart and diamond group, which is the trio people disagree about as well.
That calibration set is drawn rather than photographed, so the absolute numbers may sit a little differently for real faces even though the order of the shapes holds. It is the reason this page shows you the trace over your own photo and the raw widths underneath it, instead of asking to be taken at its word.
