Heart or diamond? Start above the chin.
Both outlines can taper at the chin. Compare the upper face and cheekbones to understand the useful difference.
Compare one clue at a time
Tap a feature. This explains the diagrams; it does not classify your face.
Heart: the upper face often looks broad relative to the jaw. Diamond: the forehead looks narrower than the cheekbone area.

The main difference
Heart-shaped faces tend to keep more width through the upper face compared with a narrower jaw. Diamond-shaped faces put more emphasis on cheekbones that are wider than both forehead and jaw. A tapered chin can appear in both, so the chin alone does not separate them.
More width through the upper face.
More width through the cheekbones.
These are styling descriptions rather than precise anatomical classes. Some guides use different definitions, and a person can reasonably fit more than one description. The heart guide and diamond guide explain how our photo comparison treats the two profiles.
Compare the whole outline
| Clue | Heart tendency | Diamond tendency |
|---|---|---|
| Upper face | Relatively broad, sometimes close to cheekbone width. | Clearly narrower than the cheekbone area. |
| Cheekbones | May be prominent without being the sole widest feature. | The strongest width emphasis of the outline. |
| Jaw and chin | Narrower toward the lower face. | Also narrows toward the lower face. |
| Hairline | A widow’s peak may be present, but is not required here. | Hairline alone does not decide the category. |
| Face length | Can vary; length alone is not enough. | Can vary; compare the width pattern as well. |
A square or round face can also have prominent cheeks. “High cheekbones” describes their vertical position, not the same thing as a diamond outline. Use the eight-shape chart if neither description fits well.
A simple way to check without chasing a label
- Use a neutral view. Face forward with your head level and avoid a very close wide-angle selfie.
- Move hair away from the temples. Hidden upper-face edges can make the forehead look artificially narrow.
- Compare upper, middle and lower width. Look for the pattern, not a tiny difference between two lines.
- Notice uncertainty. A beard, shadow or turned head can hide the lower outline. Do not guess what you cannot see.
- Choose a practical next step. Compare hair or frames for both descriptions if they are close.
If you prefer an automatic starting point, the photo detector compares eight profiles. It does not force you to pick one of these two. No manual measurements are needed for the normal photo flow.
Why tools can disagree
Two tools can choose different upper-face boundaries, measurement points and scoring rules. Even with the same landmarks, one classifier may use a strict widest-point rule while another combines length, widths and the lower outline. Their score labels can also mean different things.
On GoldenRatioFace, profile match scores are not probabilities or accuracy percentages. A small gap between the two leading profiles signals a close comparison under our rules. It is not proof that your face is a fixed percentage heart or diamond.
Our automatic length includes an estimated upper boundary; the model does not detect a true hairline. Results can change with photo angle or covered features. Check the measurement overlay and the photo instructions before treating a change in label as meaningful.
What should you do with the answer?
For hair, decide how much forehead you want to show and where you like movement. A fringe, a side sweep or a shorter cut can all be intentional choices for either outline. Texture, density and daily effort remain important. See heart hairstyles for men or the diamond hairstyle guide for practical starting points.
For glasses, compare shapes in a mirror and check physical fit. Bridge stability, frame width and whether the lenses or rims touch your cheeks matter more than matching a label. Use the glasses fit guide rather than buying from a shape chart alone.
Neither label is more attractive or more desirable. If two descriptions help you find styles you like, you do not need to settle the classification before making a choice.
Quick questions
Can I have a mix of heart and diamond features?
Yes. These are simplified descriptions of continuous variation. A broad upper face and prominent cheekbones can make both labels useful.
Does a widow’s peak mean heart shape?
Not by itself. It describes the hairline. On this site it is not required for a heart-style outline.
Does a pointed chin mean diamond?
No. Both heart and diamond descriptions can include a tapered chin. Compare the forehead and cheekbone pattern too.
Which is rarer?
This comparison does not establish rarity. Online percentages are not a substitute for a clearly defined, representative population study.
Should I keep retaking photos until the result is clear?
Take a useful photo and inspect the measurement lines. A real near tie may remain. Repeated scans are not needed to earn a more definite label.
