How does the AI face shape detector work?

Our tool uses face-api.js powered by TensorFlow.js to detect 68 facial landmark points directly in your browser. It then calculates key measurements — face width, length, forehead, cheekbones, and jawline — and classifies your face shape using proven geometric ratios. All processing happens locally on your device.

Is my photo stored or uploaded anywhere?

No. Your photo never leaves your device. All AI analysis runs entirely in your browser using WebAssembly and TensorFlow.js. We don't have a server that receives your image. This is a core feature of our privacy-first design.

What are the 6 face shape types?

The six main face shapes are: Oval (balanced, slightly longer than wide), Round (nearly equal length and width with soft curves), Heart (wider forehead, narrower jaw), Square (strong angular jaw, similar forehead/jaw width), Diamond (prominent cheekbones, narrow forehead and jaw), and Oblong (significantly longer than wide with similar top/bottom width).

How accurate is the face shape detection?

Our AI is highly accurate for clear, front-facing photos with good lighting. The detection uses 68 anatomical landmark points and geometric ratio analysis. For best results, use a photo where your full face is visible, you're looking straight at the camera, and there are no accessories covering key facial features.

What photo should I use for best results?

For the most accurate results: use a front-facing photo with your face fully visible, ensure good, even lighting (avoid harsh shadows), pull your hair back if possible, look straight at the camera, and make sure your face takes up at least 30% of the frame. Avoid glasses or face coverings.

Can I use this tool on mobile?

Yes! FaceShape AI is fully mobile-responsive and works on all modern smartphones and tablets. You can upload a photo directly from your camera roll or take a new photo using your device camera.

What do the hairstyle recommendations mean?

Each face shape has hairstyles that are most flattering for it based on established beauty principles. These recommendations aim to create visual balance — for example, adding height for round faces or width for oblong faces. They're starting points, not strict rules — personal style always wins!

What is the facial symmetry score?

Your symmetry score measures how evenly balanced your facial features are from left to right, how your proportions compare to the golden ratio (1.618:1), and how defined your jawline is. Higher scores indicate greater facial harmony. No face is perfectly symmetrical — variation is natural and beautiful.

Do I need to create an account?

No account required. FaceShape AI is completely free and requires zero sign-up. Just visit the site, upload your photo, and get your results instantly.

Why does it take a few seconds on the first use?

On your first visit, the AI model files (~6MB) need to be downloaded from our server to your browser. This is a one-time download — after that, your browser caches the models and all subsequent analyses are instant. We use lazy loading so models only download when you interact with the tool.

Can I use my camera to detect my face shape?

Yes! Our face shape detector includes a built-in camera feature. Just click 'Take Selfie', allow camera access, and capture your photo directly in the browser. Your camera turns off immediately after the photo is taken and nothing is stored.

What Is My Face Shape? Take This 60-Second Quiz

Figuring out your face shape doesn't have to be complicated. You don't need a photo, a ruler, or a math degree. Answer five simple questions about your features and you'll know your face shape in under a minute.

For the fastest, most accurate result, you can also use our free AI face shape detector — it analyzes 68 facial landmark points and gives you a definitive answer in seconds.

Why Your Face Shape Matters

Your face shape is the foundation of your personal style. It determines:

Which hairstyles will elongate, balance, or harmonize your features
Which glasses frames will complement rather than clash
Which makeup techniques will sculpt and highlight your best features
Which beard styles will define your jawline (for men)
Which earring shapes will draw the eye to your strengths

Once you know your shape, you unlock a whole new level of intentional styling.

The 5-Question Face Shape Quiz

Work through these questions honestly. If you're unsure, use a mirror or a front-facing selfie.

Question 1: What best describes your jawline?

A. Gently rounded, no sharp angles B. Soft, pointed — like a soft V or heart C. Square and defined — distinct angles at the sides D. Tapers to a narrow point — more angular than soft E. Rounded or slightly squared — about as wide as your cheekbones

Question 2: How wide is your forehead compared to your jaw?

A. About the same width B. Noticeably wider — my forehead is the broadest part C. Slightly narrower than my cheekbones D. Narrower than both my cheekbones and jaw E. Similar to my jaw, both fairly wide

Question 3: What's the widest part of your face?

A. My cheekbones — they gently curve outward B. My forehead C. My jaw — it's very prominent D. Definitely my cheekbones — they're notably wider than everything else E. Hard to tell — everything is roughly the same width

Question 4: How long is your face compared to its width?

A. About 1.5× longer than wide — balanced but slightly oval B. Shorter — my face is almost as wide as it is long C. About equal — it's a compact face D. Noticeably longer than wide E. About the same, with prominent cheekbones

Question 5: What shape best describes your hairline?

A. Slightly curved — a gentle arc B. A widow's peak or a curved V in the center C. Relatively straight across D. Straight or slightly narrow at the top E. Curved with wide temples

Quiz Results

Mostly A's — Oval Face Shape

Congratulations, you likely have an oval face — often considered the most balanced and versatile face shape. Your cheekbones are gently wider than your forehead and jaw, with a face length about 1.5× the width. Almost every hairstyle, glasses frame, and makeup look works well on oval faces.

Try: Use the AI detector to confirm your oval face shape

Mostly B's — Heart Face Shape

You likely have a heart face shape: wider forehead, prominent cheekbones, and a narrower, pointed chin — like an inverted triangle. The goal with heart-shaped faces is to minimize forehead width and add visual width around the jaw.

Best styles: Side-swept bangs, chin-length bobs, off-shoulder tops, and triangular or oval glasses.

Mostly C's — Square Face Shape

A square face shape means your forehead, cheekbones, and jaw are all roughly the same width, with a defined angular jaw. This strong, structured shape benefits from styles that soften angles and add height.

Best styles: Long layers, curls, side parts, and oval or round glasses.

Mostly D's — Diamond or Oblong Face Shape

Two possibilities here. If your cheekbones are dramatically the widest part of your face with a narrow forehead and jaw — you have a diamond face. If your face is simply much longer than it is wide with relatively consistent width — you have an oblong face.

Mostly E's — Round Face Shape

You likely have a round face: soft curves, full cheeks, and a face width nearly equal to its length. The styling goal for round faces is to create the illusion of length and definition.

Best styles: High ponytails, long layers, angular glasses, and vertical makeup techniques.

Still Not Sure?

Many people have blended face shapes — for example, an oval-round or a heart-square. That's completely normal. The quiz and the AI detector both look at the dominant characteristics of your face.

If your results feel mixed, look at your jawline first — it's usually the most distinctive feature that determines your face shape category.
