Heart vs Diamond Face Shape
Heart and diamond faces both taper toward the chin, but heart faces lead with a wider forehead while diamond faces peak at the cheekbones with a narrower hairline.
Quick answer
Same narrow chin. The forehead decides.
Both can taper to a narrow chin, so the forehead decides: diamond's is narrow, heart's wide. Diamond always needs a forehead no more than 0.73 of cheekbone width; heart scores most on a chin of 100° or tighter, whatever the forehead.
Check your shape from a photoKey difference: Whether the forehead or cheekbones dominate width
Divide forehead width by cheekbone width. Both diamond routes need a narrow forehead: 0.71 or less on a shorter face, or 0.73 or less on a longer face with a chin of 110° or tighter. Heart's strongest condition is a chin angle of 100° or tighter; temples at least 1.14 times jaw width add points.
So a very pointed chin under a narrow forehead meets both. A forehead wider than 0.73 rules diamond out.
These are photo-landmark ratios; for tape measurements, use the face shape calculator.
Which one are you? The mirror check
Use a mirror or front-facing photo, hair off your forehead and temples.
- Is your forehead about as wide as your cheekbones? Yes points to heart.
- Is your forehead noticeably narrower than your cheekbones? Yes points to diamond.
- Are your temples wider than your jaw? Yes points to heart.
- Are your cheekbones clearly the widest point, with narrow forehead and chin? Yes points to diamond.
Heart and diamond side by side
The first three rows are what a mirror shows.
| Aspect | Heart | Diamond |
|---|---|---|
| Forehead | Wider than jaw | Narrower than cheeks |
| Cheekbones | High, not always widest | Widest point |
| Chin | Narrow, sometimes pointed | Narrow, tapered |
| How the detector scores it | ∠chin ≤ 100° (strongest); + W_temple / W_jaw ≥ 1.14; + W_temple / W_jaw ≥ 1.15 with ∠chin ≥ 115° and W_forehead / W_cheek ≥ 0.70 | W_forehead / W_cheek ≤ 0.71, ∠chin 115°–122°, ∠jaw 133°–137°, L/W ≤ 1.15; or ∠chin ≤ 110°, W_forehead / W_cheek ≤ 0.73, W_jaw / W_cheek ≤ 0.89, L/W ≥ 1.18 |
| Styling aim | Balance a wider top with a narrower chin: fullness at the jaw, and frames wider at the bottom. | Add width at the forehead and chin: fringes, volume at the ends, and frames with a strong top line. |
These are scoring rules, not gates: the highest score leads.
When photos sit between both
Because both rules accept a narrow chin, many narrow-chinned faces score on both. The detector names both and shows how close you are to each.
The read tips when hairline and cheek highlight are ambiguous. A fringe or low hairline hides forehead width; overhead light makes cheekbones read wider. Pull your hair back and face even light.
Mostly heart, some diamond? The chin-weighted cuts on both lists are a safe start.
Styling implications
Both shapes want weight at the chin and both use fringes, for opposite reasons. The frame advice splits on the top bar.
Hair
Heart: a Chin-length bob, Side-swept bangs that reduce forehead width, and a Crop with fringe for men's cuts. Diamond: Chin-grazing layers, Soft bangs that fill a narrower forehead, and a Short crop with a little fringe for men's cuts. Heart avoids crown volume with a tight chin; diamond avoids tight pulled-back styles that expose the widest cheekbone line.
Frames
Oval and Rimless sit on both lists. Heart skips heavy top-bar frames that widen the forehead; diamond's men's list includes Browline, whose brow bar fills a narrower forehead. Heart adds bottom-heavy Aviator; diamond skips frames widest at the cheekbone line. Use the glasses finder, or read glasses for a heart-shaped face and glasses for a diamond face.
Beard (if you grow one)
Both put density at the chin: Fuller chin, lighter cheeks for heart, Chin-focused fill for diamond. Each avoids a sparse chin: heart under heavy cheeks, diamond under hollow ones. See the men's face shape guide.
For a blend, the hairstyle recommender ranks cuts from both lists.
Not sure if you're heart or diamond?
Upload a front-facing photo with your forehead clear. The face shape detector compares forehead, temple and jaw widths with cheekbone width, checks your chin angle and names your likely shape, or both, with a confidence label. Landmarks are found in your browser first; your photo isn't stored.

Frequently asked questions
Why does the detector show both scores?
Front-facing photos often sit between families when cheek highlight and hairline are ambiguous. The rules also overlap: a narrow chin under a narrow forehead can earn both.
Do glasses advice differ?
Heart faces avoid heavy top bars; diamond faces skip frames widest at the cheekbone line and can wear a strong top line, such as a Browline.
What if I'm somewhere between the two?
That is common. When your measurements sit near the line between two shapes, the face shape detector names both and shows how close you are to each, and styling ideas from either will work.
Does a pointed chin mean heart?
Not on its own. Both shapes can taper to a narrow chin; your forehead decides, because diamond also needs a forehead no more than 0.73 of cheekbone width.
Why does the heart rule have two routes?
Heart scores most strongly through a chin angle of 100° or tighter, plus temples at least 1.14 times jaw width. A second route rewards a wide top, temples at least 1.15 times jaw width and a forehead at least 0.70 of cheekbone width, with a broader chin of 115° or wider.
Why did my result say Medium or Lower confidence?
A fringe, temple shadow or overhead light on your cheeks held the read back, or heart and diamond scored close. Lower confidence is an honest result, not an error; a straight-on photo in even light usually firms it up.
