What Is My Face Shape? Measure It From One Photo
6 min read
Short answer
Face shape comes down to four measurements: face length, forehead width, cheekbone width, and jaw width. Two comparisons do most of the work. Whether the face is longer than it is wide, and which of the three widths is largest. Everything else is interpretation.
Classify your face shape
Upload front-facing photo. Returns the four measurements, the length-to-width ratio, the classification, a confidence score, and the two nearest alternative shapes when the result is near a boundary.
Classify my face shapeWhy the mirror method does not work
Almost every face shape guide asks you to look in a mirror and decide whether your jaw is soft or angular, or whether your face is long or average. Some suggest tracing your outline on the glass with a marker.
This does not work, for three reasons.
You cannot see your own face objectively. You have seen it thousands of times, always mirror-flipped, always from the same distance and angle. Familiarity is the enemy of assessment.
The distinctions are small. The difference between a square face and a round face is often ten degrees of gonial angle, which nobody eyeballs accurately. The difference between round and oval can be a length-to-width ratio of 1.22 against 1.31.
The categories are described in adjectives, not measurements. "Soft jaw" and "strong jaw" mean different things to different people, which is why the same man gets classified as square on one site and round on another.
The four measurements below remove all of that.
The four measurements
Face length. From the trichion, the point where your hairline begins at the centre of the forehead, straight down to the bottom of the chin.
Forehead width. Across the widest point of the forehead, roughly at the level of the brow.
Cheekbone width. Across the widest point of the zygomatic arches, usually level with the outer corner of the eye or slightly below.
Jaw width. Measured at the gonion on each side, the corner where the jaw turns upward toward the ear. Not at the chin.
From these you get one ratio and one ranking. The ratio is length divided by the largest width. The ranking is which of the three widths is biggest, and by how much.
The seven shapes
| Shape | Length-to-width | Widest at | Jaw character |
|---|---|---|---|
| Round | Under about 1.25 | Cheekbones, modestly | Soft, gonial angle above ~125° |
| Square | Under about 1.3 | All three near-equal | Sharp, gonial angle under ~120° |
| Oval | About 1.4 to 1.5 | Cheekbones, moderately | Moderate, tapers gently |
| Oblong | Above about 1.5 | All three near-equal | Moderate |
| Heart | Longer than wide | Forehead | Narrow, pointed chin |
| Diamond | Longer than wide | Cheekbones, sharply | Narrow, and forehead narrow too |
| Triangle | Varies | Jaw | The widest point of the face |
The four pairs people confuse
Round against oval is decided by length. Both are widest at the cheekbones with a soft jaw. Under about 1.25, round. Above about 1.4, oval. This is the single most common misclassification, and it matters because the styling advice differs substantially.
Square against round is decided by the jaw, not the outline. Both can be roughly as long as they are wide. Square has a gonial angle under about 120 degrees, meaning a visible corner where the jaw turns upward. Round has an obtuse angle above about 125 degrees and no visible corner. Two faces with identical outlines can be different shapes because of this.
Square against oblong is decided by length alone. The width profile is identical, three near-equal measurements. Under about 1.3, square. Above about 1.5, oblong.
Diamond against heart is decided by the forehead. Both have narrow chins. Heart has a wide forehead, wider than the cheekbones or close to it. Diamond has a narrow forehead, which is exactly why the cheekbones read as so pronounced.
Why the boundaries are fuzzy, and why that is fine
Face shape is a category imposed on a continuum. Real faces land between labels, and a man with a 1.32 ratio is genuinely between square and oblong rather than secretly one of them.
This matters for what you do next. If you sit near a boundary, the styling guidance for both neighbouring shapes will contain useful ideas and neither will be wrong. What does not work is picking a label, following its rules rigidly, and ignoring your own proportions.
We report your actual ratios alongside the classification, and flag a lower confidence score when your measurements sit near a boundary. Two nearest alternatives are shown in that case, so you can read both guides.
Why different tools classify you differently
The trichion problem. Face length is measured from the hairline, and hairlines recede. On a mature or receding hairline there is no stable point to measure from, and where a tool places the trichion can change your length-to-width ratio by enough to move you between categories. This is the biggest single source of disagreement between face shape tools, and almost nobody mentions it.
What we do: detect hairline recession and, where it is present, lower the confidence score on the classification and report the ratio range rather than a single value. If your result comes back with low confidence and you have a receded hairline, that is why.
Camera distance. A phone held close introduces perspective distortion that widens the centre of the face relative to the edges. Your cheekbones read wider and your jaw reads narrower than they are. Shoot from arm's length or further.
Head rotation. Any yaw makes one side of the face read narrower. We detect this and reject photos beyond a rotation threshold rather than returning a bad number.
Where the jaw is measured. Some tools measure jaw width at the chin, which produces completely different classifications. The gonion is the correct landmark.
Full method: Methodology
What face shape does and does not tell you
It is useful for: choosing a haircut, choosing a beard shape, choosing glasses frames. All three are decisions about visual balance, and knowing your proportions genuinely helps.
It is not useful for: predicting anything about you as a person, or ranking your face against others. Face shape is a description of geometry. Attractiveness is not a shape and none of the seven is the good one, whatever the internet implies about ovals.

FAQ
How do I find my face shape accurately?
Measure rather than judge. You need face length, forehead width, cheekbone width, and jaw width at the gonion, then the ratio between length and the largest width. Doing this by eye in a mirror is unreliable because the differences that separate shapes are often small.
What is the most common face shape for men?
Oval and oblong are the most frequently reported in men, though this varies by population and by how a given study draws its category boundaries. There is no single reliable figure.
Can your face shape change?
The underlying bone structure is stable in adulthood. What changes is the soft tissue over it. Significant weight change alters the apparent width of the lower face and can shift how a face reads between categories without any change to the skeleton. Ageing also affects it through soft tissue descent.
Which face shape is best?
None. Oval is often described that way because it is the shape other advice tends to steer toward, but that is a convention within styling guidance rather than a finding about attractiveness.
Why does every website give me a different face shape?
Usually the hairline. Face length is measured from the trichion, and on a receded hairline that point is a judgement call that can shift your ratio across a category boundary. Camera distance and where the jaw is measured also contribute.
Do I measure my jaw at the chin or the corner?
The corner, at the gonion, where the jaw turns upward toward the ear. Measuring at the chin gives a completely different classification.
