Free AI Tool — Ratio-by-Ratio Breakdown
Golden Ratio Analyzer
A golden ratio analyzer is an AI tool that maps your facial landmarks, measures three specific proportions against φ (roughly 1.618), then scores each one on how close it lands — instead of folding everything into a single average that hides which one is actually off.
Two people can post the exact same overall score for opposite reasons: one because every ratio sits near 1.618, the other because two strong ratios are propping up a weak one. Upload a photo and this tool tells you which situation you're looking at, using the same 68-point landmark map that runs every measurement tool on the site. Two free scans a day, no account needed, and nothing you upload sticks around after the result comes back.

The Three Measurements
Ask three separate questions about a face instead of one, and the answer tells you a lot more than a single blended score ever could.
Lower vs mid-face
Nose-to-chin length set against eyes-to-nose length.
Inside the lower face
Nose-to-chin length set against mouth-to-chin length.
Scored by distance
The nearer a ratio lands to 1.618, the higher it scores.
Phi (φ) comes out to roughly 1.618 — the split where the whole relates to the larger piece the same way the larger piece relates to the smaller one. It turns up in geometry, in a handful of growth patterns, and in an enormous amount of writing about facial beauty.
What that writing usually leaves out: nobody has produced solid evidence that faces sitting closer to 1.618 get rated as more attractive. The claim gets repeated often enough to sound settled, and it isn't. So this tool sticks to what it can measure — three proportions, three numbers — and stops there.
Each of the three measurements comes back with its own ratio and its own distance from 1.618, never collapsed into one figure. That distinction matters: an overall average can look perfectly healthy while one ratio sits far outside the range, and that outlier is usually the more useful thing to know.
Reading the Numbers
A score near 100 means one specific thing: that ratio sits close to 1.618. It isn't a verdict on how your face looks.
Within 0.15 of φ
Very close
That ratio lands almost exactly on 1.618.
Within 0.35 of φ
Near
In the range most faces fall into.
Further than 0.35
Well away
Common, and nothing to read into. Faces vary this much as a matter of course.
Getting Reliable
Measurements
Every one of these three ratios comes from a vertical distance, so anything that tilts your chin up or down distorts the whole set before the math even starts.
Camera at eye level
Shooting from above or below compresses the vertical gaps this tool depends on.
Whole face in frame
Your brow line and your chin both need to be visible and uncropped.
Neutral expression
An open mouth shifts the chin measurement more than most people expect.
Hair off the forehead
The brow line anchors two of the three ratios, so covering it costs you accuracy twice over.

Where the Golden Ratio Claim Comes From
Trace the idea that beautiful faces follow φ back far enough and you land on Renaissance art on one side and a batch of 20th-century measurements of so-called "ideal" faces on the other. It stuck around because it's memorable, and because a mathematical explanation for beauty makes a satisfying story.
Here's the catch: a human face offers dozens of distances you could divide against each other. Test enough pairs and a few will land near 1.618 on almost anybody, which makes the pattern easy to find after the fact and useless for predicting anything beforehand.
This tool doesn't go pair-hunting for a flattering result. It runs the same three fixed ratios on every photo, which makes your numbers comparable to someone else's in a way a hand-picked set of measurements never could be.
Why We Show Each Ratio Separately
An overall figure is a weighted average, and averages smooth over exactly the detail worth seeing. On one reference measurement we ran ourselves, the overall score came out at 85.6 — while one of the three ratios sat at 2.058, more than 0.4 away from 1.618, scoring just 61.9 on its own.
Report only the 85.6 and that face "closely matches the golden ratio." Report all three and a different picture shows up: two proportions sitting near φ, one clearly not. The second version is the useful one, so it's the one this page gives you every time.
What This Cannot Tell You
It can't tell you whether your face is attractive. Symmetry and proportion happen to be two of the only things about a face you can measure from a photograph, which is exactly why so much writing treats them as though they were what matters most. They're simply the measurable ones — that's the entire basis for their reputation.
It also can't measure your forehead height with any accuracy, because the 68-point landmark standard — the same one behind the landmark map — has no point for the hairline. Every measurement on this page starts at the brow line for that reason; nothing above it factors into the result.
About This Tool
Who's behind the math on this page? Ahsan Fayyaz, who trained the measurement engine in-house on real faces and benchmarked it against other proportion-analysis tools rather than licensing one from a third party. It's the same engine behind every landmark-based tool on the site, including the phi-mask overlay and the landmark map. It's a geometric measurement offered for informational and entertainment purposes only, not medical, clinical, or professional advice of any kind.

Frequently Asked Questions
It places 68 landmark points on your photo, measures five vertical distances between them, turns those into three ratios, and scores each one by how close it sits to 1.618.
It's a proportion, roughly 1.618, where the whole relates to the larger of two parts the same way that larger part relates to the smaller one. Mathematicians call it φ (phi).
No. It means one or more of your three measured ratios sit close to 1.618 — nothing more. There's no solid evidence tying that proportion to attractiveness, so treat the score as a geometry reading, not a beauty verdict.
Because an average can hide a lot. On one measurement we ran ourselves, the overall came out at 85.6 while a single ratio sat at 2.058 — over 0.4 away from φ — and scored only 61.9 alone. Reporting all three catches that; reporting one number would have buried it.
Upper vs lower face (brow-to-chin over nose-to-chin), lower vs mid-face (nose-to-chin over eyes-to-nose), and inside the lower face (nose-to-chin over mouth-to-chin).
They're distance bands from 1.618: within 0.15 is Very close, within 0.35 is Near, and anything further out is Well away. Well away is the most common result and isn't a problem — faces vary that much naturally.
No. The 68-point landmark standard has no hairline point, so forehead height can't be measured reliably. Every ratio here starts at the brow line instead.
Your photo is processed by our own in-house model, not a third-party service, and deleted from the server immediately after your result is generated. What you see afterward lives only in your browser's cache — refresh the page and it's gone for good on both ends.

Yes, more than most people expect. All three ratios come from vertical distances, so tilting your chin up or down compresses those distances and skews every ratio at once. Shoot at eye level.
It can. A wide smile or open mouth shifts the chin landmark, which feeds directly into two of the three ratios. A neutral, ID-photo-style expression holds up better.
Same 68-point measurement, different presentation. This page gives you the three raw ratios and their scores as numbers; the phi-mask tool draws that same geometry as an overlay directly on your photo so you can see where each measurement falls.
Because faces aren't uniformly proportioned, and there's no reason they should be. One ratio landing at 61.9 while the other two sit above 90 just means that particular distance pair happens to sit further from 1.618 on your face than the others do — common, and not something to fix.
Yes. The brow line anchors two of the three ratios, so hair falling across it can throw off both at once. Push it back before you scan.
Up to your two free scans. Small changes in angle or lighting between attempts are usually enough to shift the numbers slightly, so a second try with a cleaner photo can give a steadier read.
Yes. The underlying model runs the same 68-point detection and the same three ratios regardless of who's in the photo.
Mostly Renaissance art and a set of 20th-century measurements of "ideal" faces. It stuck around because it's a memorable, satisfying explanation — not because it's been proven. A face offers dozens of distances to divide against each other, and some will always land near 1.618 by chance.
