The golden ratio — written as the Greek letter phi (φ) — is approximately 1.618. It's the proportion you get when a line is divided so that the whole length relates to the longer part in the same way the longer part relates to the shorter one. It turns up in mathematics, architecture and art, and for centuries people have suggested that the most beautiful faces are built from it too.
A "golden ratio face" is one where key features relate to each other in roughly that 1.618 proportion — for example, a mouth that's about 1.6 times as wide as the nose. The idea was popularised in modern times by maxillofacial surgeon Stephen Marquardt, whose "beauty mask" overlay maps dozens of φ-based proportions onto a face.
This free golden ratio face calculator measures three classic golden ratio proportions on your face from a single photo and tells you how close each one is to 1.618.
When you upload a front-facing photo, the calculator runs Google's MediaPipe Face Mesh in your browser — your photo isn't uploaded — and places 478 landmarks on your face. It then measures three ratios that golden ratio guides commonly use:
| Ratio | How it's measured | Golden ideal |
|---|---|---|
| Mouth vs nose width | Width of your mouth ÷ width of your nose at the nostrils | 1.618 |
| Chin proportions | Nose base to chin ÷ lower lip to chin | 1.618 |
| Eye vs mouth width | Distance between your outer eye corners ÷ width of your mouth | 1.618 |
Each ratio gets a score out of 100. A ratio that exactly matches 1.618 scores 100; one that's 10% away scores 85; one that's 20% away scores 70. Your overall golden ratio score is the average of the three, and you can see each ratio's actual value next to the 1.618 target.
All three are ratios between distances on your own face, so the result doesn't depend on how large your face is in the photo.
| Score | What it means |
|---|---|
| 90–100 | Your measured proportions align almost perfectly with the golden ratio |
| 80–89 | Excellent facial balance, close to golden proportions overall |
| 70–79 | Good proportions with some individual variation |
| Below 70 | Distinctive proportions that depart from the golden standard |
What does an 80% golden ratio score mean? It means that, on average, your three ratios are within roughly 13% of 1.618. That's a strong result — very few real faces land close to φ on every measurement, and a score in the 70s is already well within the normal range for attractive faces.
The golden ratio makes a great story, but the research behind it is weaker than its popularity suggests:
So use your golden ratio score as an interesting, structured look at your proportions — not as a beauty verdict. A face can score in the 60s here and still be very attractive.
People often use "golden ratio" loosely to mean any measure of a well-proportioned face. These are actually different measurements, and each has its own tool:
For a single number that combines several of these, the facial harmony score blends seven proportions.
If your results vary between photos, that's usually down to expression, angle or distance — use the photo that best follows these tips.
The proportions measured here are mostly set by bone structure, so they don't change with exercises. Some things do shift the numbers:
A golden ratio face is one where key features relate to each other in the proportion 1.618 (phi) — for example, a mouth about 1.6 times as wide as the nose. It's a classical ideal of beauty, popularised by Stephen Marquardt's golden ratio "beauty mask".
Upload a straight-on, neutral-expression photo to this calculator. It measures three classic ratios — mouth to nose width, nose-to-chin to lip-to-chin, and outer eye distance to mouth width — and compares each with 1.618.
A score of 80 or above is excellent, and 70–79 is good. Above 90 means your measured proportions align almost perfectly with the golden ratio, which is rare.
It means your three measured ratios are, on average, within about 13% of the 1.618 ideal. That's a strong result — most attractive faces don't match the golden ratio closely on every measurement.
Not really. Research suggests that averageness and symmetry predict attractiveness better than the 1.618 ratio. A 2010 study found faces looked most attractive at proportions close to the average face — eyes-to-mouth at about 36% of face length — rather than at phi.
This calculator focuses on proportions rather than left–right symmetry. To measure how symmetrical your face is, use the free face symmetry test, which compares eight left–right feature pairs.
Lists ranking celebrities by how closely they match the golden ratio appear in the media regularly, but they're usually based on a single photo and a particular choice of measurements. No real face matches 1.618 on every proportion.
There's little evidence of it. Da Vinci's famous Vitruvian Man drawing is based on the Roman architect Vitruvius's body proportions, which use simple fractions rather than the golden ratio. The da Vinci connection is mostly a modern myth.
No. A lower score just means your proportions differ from the 1.618 standard. Many very attractive faces score in the 60s or 70s, because real-world attractiveness depends far more on overall harmony, symmetry, skin and expression.
Golden ratio guides also describe profile proportions, such as the relationship between nose, lips and chin. This calculator measures the front of the face only, so use a straight-on photo.
