Six ratios · ten reference shapes · zero uploads
Your face has a geometry.
Let’s measure it.
Type in five measurements or hand it a photo — on-device AI finds your landmarks, does the math, and shows you exactly why it landed on your shape. Nothing is ever sent anywhere.
Quick answer
This free face shape calculator finds your face shape from five facial measurements — face length, forehead width, cheekbone width, jaw width and chin width. Enter them manually or let on-device AI read them from a photo. It’s built for anyone choosing a haircut, glasses or beard style and wants a proportion-based answer rather than a guess. You get a top match plus a full confidence breakdown across all ten recognized face shapes, so you can see how close a call it was — not just one label.
Step one
Take your measurements
Use a soft measuring tape against a mirror, or let the camera find your landmarks automatically.

Method
How the calculation works
Measure six ratios
Length-to-width, forehead-to-cheekbone, jaw-to-cheekbone, chin-to-jaw, forehead-to-jaw, and jaw angle.
Compare to ten profiles
Each ratio is scored against reference values for oval, round, square, heart, diamond and more.
Weight by reliability
Ratios that vary less between people carry more weight in the final confidence score.
Show the working
You see every shape’s score, not just the winner — so you can judge a close call yourself.
The five measurements above follow standard craniofacial anthropometric landmarks — trichion, zygion, gonion and gnathion — the same reference points used in clinical facial-proportion research. Photo mode locates them with Google’s open-source MediaPipe Face Landmarker model (a 468-point face mesh); manual mode uses the same landmarks measured by hand with a tape. Face-shape names are a styling convention, not a formal medical classification — treat the result as styling guidance rather than a diagnosis.
Questions
Frequently asked
Is my photo uploaded anywhere?
No. Face detection runs entirely inside your browser using TensorFlow.js. No image data is sent to a server, ever.
How accurate is the result?
It’s ratio-based, not a black box: the same six measurements a stylist would take are compared against reference profiles for ten shapes, and you can see the full confidence breakdown, not just the top pick.
What if the camera doesn’t detect my face?
Use even, front-facing light, remove glasses if they cause glare, and keep your full face and hairline inside the frame. Manual measurements always work as a fallback.
Does this work on mobile?
Yes — both the manual form and the camera flow are fully responsive and support front/rear camera switching on phones.
