Face Shape Detector: Find Your Exact Face Shape with AI
Upload or capture a clear photo and our on-device AI maps 478 3D facial landmarks (including 10 iris landmarks) to precisely analyse your face length, jawline, cheekbones and forehead — then reveals your face shape along with personalised hairstyle, beard and glasses recommendations.
Quick answer: A face shape detector uses AI to map facial landmarks in a photo and compare forehead, cheekbone, jaw and length proportions to identify your face shape — free, instant, and processed entirely in your browser.

What Is Face Shape Detection?
Face shape detection is the process of analysing the geometric proportions of a human face — including the width of the forehead, cheekbones and jaw, overall face length, and jaw angle — to classify it into a recognised category such as oval, round, square or heart. Historically done by eye by hairstylists and makeup artists, it can now be automated using computer vision: an algorithm identifies dozens of specific points on the face (called landmarks) and measures the distances and angles between them.
This tool uses that same landmark-based approach, applying it instantly and privately inside your browser so you get an objective, repeatable analysis rather than a subjective guess. Prefer not to use a camera at all? You can also check your face shape manually with a tape measure.
How This Tool Works
Every analysis runs in four simple, fully automated steps:
Upload or Capture
Provide a clear, front-facing photo by uploading a file, dragging and dropping, or using your device camera.
Landmark Mapping
An on-device AI model maps 478 3D facial landmarks across your forehead, eyes, cheeks, jaw and chin, including 10 iris landmarks (5 per eye).
Proportion Analysis
Key ratios are calculated — length-to-width, forehead-to-jaw, cheekbone-to-jaw, and jaw angle/curvature.
Shape Classification
Your proportions are matched against ten defined face shape profiles to find the closest match, with a confidence score.
Detection Technology
The detector uses a 478-point 3D facial landmark model. Every landmark is a point on your face with x, y and z coordinates. The 478 points cover the face outline, forehead, eyebrows, eyes, nose, lips and jaw, and include 10 iris landmarks (5 for each eye). It is the MediaPipe Face Landmarker, and it runs entirely in your browser.
What this means for your result: your face shape is worked out from a small set of these points: the top of the forehead, temples, cheekbones, jaw corners, chin and jaw angle. From these the tool calculates length-to-width, forehead-to-jaw and similar ratios. The iris landmarks are part of the model’s output but are not used in the current classification, and the tool does not use all 478 points to decide your shape. A more detailed landmark model does not by itself guarantee a more accurate result: accuracy still depends on photo angle, lighting, expression and hair coverage, and this tool’s classification has not been independently validated.

How to Check Your Face Shape Manually
Prefer not to upload a photo? You can estimate your face shape with a soft tape measure or a washable marker and a mirror. Pull your hair back and take these four measurements:
Forehead Width
Across the widest part of your forehead, roughly one finger above the eyebrows.
Cheekbone Width
Between the highest points of your cheekbones, just below the outer corners of your eyes.
Jawline Width
From one jaw corner to the other, across the widest part of your jaw.
Face Length
From the center of your hairline straight down to the tip of your chin.
Compare the four numbers against the reference chart below — the two signals that separate most shapes are your length-to-width ratio and which width measurement is largest. Manual measurement is a reasonable estimate; the AI detector above accounts for more points and curvature, so the two methods can differ slightly — that’s normal, not an error in either one.
How Accurate Is the Detection?
This tool relies on real geometric measurement — not a randomized or hardcoded output — so results are consistent for photos taken under similar conditions. It classifies your face by comparing measured proportions (length-to-width, forehead-to-jaw, cheekbone-to-jaw, and jaw angle) against defined face shape profiles, and shows a confidence score so you can see how close a match it is.
Accuracy can be affected by: photo angle and distance, lighting and shadows, hair covering the forehead or jaw, facial expression, and image quality. Many real faces sit between two categories — that’s a normal outcome, not a flaw in the measurement. This tool is a styling aid, not a medical or clinical measurement device, and it does not store or transmit your photo.

Frequently Asked Questions
What is a face shape detector and how does it work?
A face shape detector analyses the geometry of your face — including forehead width, cheekbone width, jaw width and face length — using facial landmark detection, then compares those proportions against known face shape categories such as oval, round, or square.
How accurate is this face shape detector?
It uses real facial landmark detection to measure over ten facial proportions, producing highly consistent results for clear, front-facing photos. Accuracy can vary slightly with lighting, hair coverage, and camera angle.
What face shapes can this tool detect?
It can detect ten face shapes: oval, round, square, rectangle, oblong, heart, diamond, triangle, pear, and inverted triangle.
Is my uploaded photo stored or shared with anyone?
No. All processing happens directly in your browser via on-device AI. Your photo is never uploaded to a server or stored anywhere.
What is the best type of photo to upload for accurate results?
Use a clear, well-lit, front-facing photo with hair pulled back, a neutral expression, and no sunglasses or hats.
Can I use this tool on my phone?
Yes, it is fully mobile-optimised and supports both photo upload and direct camera capture on smartphones and tablets.
Is this face shape detector free to use?
Yes, the tool is completely free with no sign-up or payment required.
