Face Shape Detector — Know Your Face Shape in Seconds

FaceShapeSnap is a free AI face shape detector that analyzes a front-facing photo to identify which of seven face shapes matches your facial proportions. It runs entirely in the browser, requires no account, and returns a result in about a second along with links to matching style guides.

What is FaceShapeSnap?

FaceShapeSnap is a browser-based face shape detector that takes a single front-facing photo (JPG or PNG, up to 10 MB, uploaded or captured with your camera) and outputs one of seven face shape labels: oval, round, square, heart, diamond, oblong or triangle. The analysis runs locally on your own device rather than on a server, and the result links directly to hairstyle, glasses and makeup guides for that shape.

How does the face shape detector work?

The detector locates dozens of facial landmarks — forehead edges, cheekbone points, jaw corners and chin tip — then measures the real distances between them and the angle of the jaw. Those measurements become ratios comparing forehead width against cheekbones and jaw, and face length against face width, which determine the final shape classification. The whole process takes roughly one second and never uploads your photo.

Key Features

• Seven-shape classification — sorts every face into oval, round, square, heart, diamond, oblong or triangle based on measured proportion ratios rather than visual impression.
• On-device analysis — the photo is processed in the browser and never sent to FaceShapeSnap servers.
• Instant result — landmark detection and shape output complete in about a second, with no measuring tape or manual comparison.
• Upload or camera input — accepts JPG and PNG files up to 10 MB, or a photo taken directly with your device camera.
• Built-in style guides — each result links to hairstyle, glasses and makeup ideas matched to the detected shape.
• No account required — no sign-up, no email and no watermark; the tool can be run repeatedly for free.
• Cross-device support — works in any modern browser on phone, tablet or desktop.

Who is it for?

• Everyday users — anyone deciding on a new haircut or buying glasses who wants an objective read on their facial proportions before choosing.
• Hairstylists and barbers — professionals who want a quick proportion check on a client's face before recommending a cut.
• Makeup artists — artists planning contouring or feature-balancing makeup who need the client's shape as a starting point.
• Style content creators — people producing hair, glasses or makeup recommendations who need a fast way to classify a face shape.

Use cases

• Pre-haircut check: upload a front-facing selfie, get your shape, and open the matching hairstyle guide before booking an appointment.
• Glasses shopping: identify whether your face is angular or rounded so you can pick frames that balance your jawline and cheekbones.
• Makeup planning: use the detected shape to decide where contour and highlight should go for your proportions.
• Client consultations: stylists and makeup artists can run a client's photo through the detector to ground style suggestions in measured ratios.

FAQ

How many face shapes can the detector identify?

It returns one of seven results: oval, round, square, heart, diamond, oblong and triangle. Each shape is defined by which part of the face is widest, the jawline profile, and whether the face is longer than it is wide.

Do I need to create an account to use it?

No. There is no sign-up and no email required — you upload or capture a photo and receive your result immediately. The tool is free to use as many times as you like, with no watermark on the output.

Is my photo stored or uploaded?

No. The analysis runs entirely in your browser, so the photo is processed on your own device and never leaves it. FaceShapeSnap states that images are not uploaded to its servers.
