"Diamond" is the third check the analyzer runs, and it's the only category defined purely by the cheekbones being the widest point of the face. Here's exactly what triggers it and how to style it.
As with every result on this site, that measurement comes from a photo processed entirely on your device via MediaPipe's on-device model — it's never uploaded, stored, or seen by anyone but you. See the privacy policy for the full picture.
Diamond is assigned when your measured cheek width is more than 5% wider than both your forehead width and your jaw width — specifically, cheek width exceeds forehead width × 1.05 and jaw width × 1.05 at the same time. In plain terms: your cheekbones are clearly the widest measurement on your face, with both your forehead and jaw narrower than that by a meaningful margin, rather than one or the other being close to cheekbone width.
It runs after the heart and triangle checks (which look at forehead-vs-jaw imbalance) but before the length-based oval/oblong checks. That ordering means a face could have cheekbones that are the widest point and be notably long, but as long as it doesn't also show a heart or triangle forehead/jaw imbalance, the cheekbone-dominance pattern takes priority and it's classified as diamond rather than oval or oblong.
Styles that add width at the forehead or jaw — like a soft fringe, side-swept bangs, or layers that flare out at jaw length — help balance prominent cheekbones by adding visual width elsewhere. Center parts with hair pulled straight back can emphasize cheekbone width since nothing softens or adds width at the temples. Chin-length bobs with waves are a commonly cited flattering option, since the waves add jaw-area width precisely where this shape is narrowest.
High, defined cheekbones are frequently highlighted as a desirable feature in makeup and styling content generally (contouring techniques exist specifically to create the appearance of more cheekbone definition) — the suggestions above are about balance and framing options, not correcting a flaw. Plenty of diamond-shape style guidance is about highlighting the cheekbones rather than minimizing them.
Because diamond is checked before the length-based rules, a face with pronounced cheekbone width but also a long length-to-width ratio will still be labeled diamond rather than oval or oblong — the cheekbone-dominance pattern is treated as more specific and takes priority. If your result surprised you because your face also looks notably long, that's why — see the full threshold breakdown for the complete decision order.
This category depends on clean forehead, cheek, and jaw width measurements all at once — hair covering any one of those three areas can shift the comparison. See how to take a photo for an accurate result.
Is diamond rare compared to other shapes? This tool doesn't track aggregate statistics across users — each analysis is private and independent, so there's no data here on category frequency.
What if my cheekbones are only slightly wider than my forehead and jaw? If the difference is under 5%, the diamond condition won't trigger, and the classifier moves on to the length-based checks instead — you might land in oval, oblong, square, or round depending on your other measurements.
Does makeup contouring affect the photo analysis? The model reads landmark geometry from skin-surface edges it detects visually, so heavy contouring that creates strong shadow lines could, in principle, slightly influence detected edges — a bare-face, even-lit photo gives the most geometrically accurate reading.
