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.

How to Find Your Face Shape: The Complete Guide

Knowing your face shape is the foundation of personalized beauty and grooming. It guides everything from which hairstyles will flatter you most to how you should apply makeup or shape your beard.

The 6 Main Face Shapes

There are six primary face shapes: Oval, Round, Heart, Square, Diamond, and Oblong. Each has distinct characteristics that make certain styles more flattering.

Method 1: Use Our Free AI Tool

The fastest and most accurate method is to use our AI face shape detector. Simply upload a front-facing photo and the AI will analyze 68 facial landmark points to classify your face shape with precision.

Method 2: Measure Your Face at Home

If you prefer not to use a photo, you can measure your face with a flexible tape measure or ruler:

Forehead width — Measure across your forehead from hairline to hairline at the widest point
Cheekbone width — Measure from the outer corner of one eye to the outer corner of the other
Jawline width — Measure from the tip of your chin to below your ear, double it
Face length — Measure from the middle of your hairline to the tip of your chin

Interpreting Your Measurements

Oval: Face length is about 1.5× the width. Forehead slightly wider than jaw
Round: Width and length nearly equal. Soft, curved lines
Heart: Forehead is wider than jaw. Narrow, pointed chin
Square: Forehead, cheekbones, and jaw are roughly equal. Angular jaw
Diamond: Cheekbones are widest. Narrow forehead and jaw
Oblong: Face length is significantly greater than width

Which Face Shape Is Most Common?

Oval is often considered the most common face shape among women, while square and round shapes are more common in men. However, most people's faces are a blend of shapes rather than a perfect example of one type.

Does Face Shape Change with Age?

Yes, face shape can shift subtly over time due to changes in bone structure, fat distribution, and skin elasticity. Many people find their face becomes slightly more oval-shaped as facial fat redistributes with age.

Getting the Most Accurate Result

For the best AI detection:

Use a high-resolution, front-facing photo
Ensure even, natural lighting
Pull your hair back so your face outline is fully visible
Look directly at the camera
Avoid tilting your head
