What’s your face shape?

Face shape detector: a quick overview

The DetectMyFaceShape face shape detector is a free online tool that identifies your face shape in seconds using artificial intelligence. Instead of asking you to guess from a set of diagrams or answer a personality-style quiz, it takes real measurements from your photo or live camera feed and compares them against the geometric proportions of the seven recognized face shapes: oval, round, square, oblong, heart, diamond, and triangle. The result is a fast, objective answer to one of the most-searched beauty and grooming questions online — “what is my face shape?” — backed by actual numbers rather than opinion.

How the detection works

Under the hood, the detector runs Google’s MediaPipe Face Landmarker, a machine-learning model that maps 478 facial landmarks across your face. From those points it calculates the ratios that define a face shape: overall face length versus width, forehead width, cheekbone width, jaw width, the angle of the jawline, and how sharply the chin tapers. Each measurement is scored against every shape’s ideal profile, so you not only see your best match but also a confidence score that tells you how clear-cut the result is. Because many faces sit naturally between two categories — round and oval, or heart and diamond — that score is often just as useful as the label itself.

Private by design

Privacy is built into the design. Everything happens on your device, directly in the browser, using on-device machine learning. Your camera feed and any photo you upload are never sent to a server, never stored, and never shared. There is no sign-up, no watermark, no ads, and no limit on how many times you can use it, which makes the tool equally suited to a quick one-off check or careful experimentation with different photos and lighting. It also works entirely in modern desktop and mobile browsers — Chrome, Safari, Firefox, and Edge — so you can analyze your face on a phone using the front camera or on a laptop using a favourite photo, with no app to install and nothing to download.

Why your face shape matters

Knowing your face shape is the practical starting point for almost every personal-styling decision. It helps you choose hairstyles and haircuts that balance your proportions, glasses and sunglasses frames that complement your features, beard styles that flatter your jawline, and makeup and contouring techniques suited to your bone structure. Hairstylists, barbers, opticians, and makeup artists all rely on face shape as a reference, so having an accurate answer turns vague advice like “add some layers” into concrete choices that genuinely suit you.

Whatever you call it — every shape covered

People find this page in many different ways, and it works the same whatever you call it. Whether you search for a face shape detector, face shape analyzer, face shape finder, face shape calculator, face shape identifier, or an AI face shape scanner, this is the tool for the job. It answers the common questions people type — “what is my face shape”, “how to find my face shape”, “what face shape do I have”, and “how to determine my face shape” — and it works equally well as a face shape test for men and women. Every one of the seven types is covered in depth, so you can confirm whether you have an oval, round, square, oblong (rectangle), heart, diamond, or triangle (pear) face shape, along with the traits that set each one apart.

Styling and measuring by face shape

Because face shape drives so many styling choices, the guidance here connects naturally to the searches that follow. That includes hairstyles and haircuts for your face shape, the best glasses, eyeglasses, and sunglasses frames for your face shape, beard styles for your face shape, and makeup and contouring by face shape. If you would rather measure by hand, the tool also supports the how-to-measure-your-face-shape cluster — face length, forehead width, cheekbone width, and jaw width — and the face-shape-from-a-photo approach, letting you detect your shape from an uploaded picture or a live camera scan.

Getting the most accurate result

To get the most accurate reading, use a sharp, well-lit photo taken straight on at eye level, pull your hair away from your face and ears, keep a neutral expression, and remove glasses. From there, the guide above and the detailed sections below walk through each of the seven shapes, how to measure your face manually if you prefer, and the styling tips that work best for every type — so you can go from “I’m not sure” to a confident, informed decision in under a minute.

How the face shape detector works

Our free face shape detector uses Google’s MediaPipe Face Landmarker, a machine-learning model that maps 478 precise landmarks across your face in real time. Unlike quizzes that rely on guesswork, the tool takes actual measurements from your photo or camera feed and compares them against the geometric proportions of the seven recognized face shapes.

Face shapes explained: which one are you?

Every face is unique, but nearly all faces fall into one of seven broad categories defined by the relationship between face length, forehead, cheekbones, jawline, and chin. Knowing your category makes choosing hairstyles, beard styles, glasses, and makeup dramatically easier, because most styling advice is written per face shape.

How to determine your face shape manually

Don’t want to use the camera? You can measure your face shape the old-fashioned way with a soft measuring tape and a mirror. Take these four measurements:

1. Face length — from the middle of your hairline to the tip of your chin.
2. Forehead width — across the widest part of your forehead, usually halfway between your eyebrows and hairline.
3. Cheekbone width — from the sharpest point below the outer corner of one eye to the same point on the other side.
4. Jaw width — from one corner of your jaw (below the ear) to the other, following the jawline.

Then compare: if length is noticeably greater than width with balanced features, you’re likely oval or oblong. If length and width are similar, you’re round or square depending on how angular your jaw is. A forehead wider than the jaw points to heart, the reverse points to triangle, and cheekbones far wider than both suggest diamond. Our detector runs exactly this comparison — just with pixel-level accuracy and no measuring tape.

Why knowing your face shape matters

Your face shape is the starting point for almost every personal-styling decision. Hairstylists use it to choose cuts that balance your proportions, opticians use it to recommend frames that complement rather than repeat your features, makeup artists contour based on it, and barbers shape beards around it. Knowing whether you’re round, oval, or heart-shaped turns vague advice like “get layers” into concrete choices that actually suit you. It’s also just fun — face shape is one of the most-searched beauty questions in the world, and now you can answer it in seconds with real measurements instead of a guess.
