Add a face
Drop a portrait, paste one, or take a photo with the camera. Hair back, glasses off and a straight head give the steadiest read.
Free tool
Face shape detector, from one photo.
Add a photo of your face or take one with the camera. A small face model finds 478 points on it, the page measures your forehead, cheekbones, jaw and face length, and picks the closest of six shapes. You see the lines on your photo, the numbers and the rule table, and you can drag any point if it landed wrong. It is a rough guide, and nothing is uploaded or stored.
or
- Face the camera, with the head level and the mouth closed.
- Pull hair back off the forehead and the sides of the face.
- Take glasses off if you can, and use even light.
- The face should fill a good part of the photo, with the whole head and chin in view.
Drag any white point if it sits in the wrong place, and the answer updates. The top point is a guess at the hairline.
How the shape was picked
Four numbers are measured on your photo and compared with typical numbers for each shape. The closest row wins and the next closest is the runner-up. The typical numbers are rules of thumb chosen by hand for this landmark model, not results of a study.
Length is face length divided by cheekbone width. Jaw and forehead are their widths divided by cheekbone width. Chin angle is the angle at the chin between the two jaw corners: small is pointed, large is flat.

Closest shape
Measured
A rough guide from proportions, not a fixed truth. It does not guess age or looks.
This runs in your browser. Your photo is never uploaded or stored.
How it works
Photo in, shape and numbers out.
02 / Measure
See the lines
The page marks the forehead, cheekbones, jaw, chin and the top of the face on your photo, and shows each number it measured.
03 / Match
Get the closest shape
The nearest of six shapes is picked from a table you can read, with a runner-up. Drag a point and the answer updates.
Guide
How to find your face shape, and what the number means.
A face shape detector measures the proportions of your face and matches them to the nearest common shape: oval, round, square, heart, diamond or oblong. This free one works from a single photo. It is an AI face shape detector in the plain sense that a small neural network finds 478 points on the face in your browser tab. After that it is simple arithmetic and a table you can read, so you can see why you landed on a shape instead of just being told. The photo is not uploaded.
How to use it
- Click Use the camera and press Take the photo, or drop a photo on the box, paste one with Command V or Ctrl V, or click it to choose a file.
- Wait a moment. The first time, the face model downloads (about 19 MB) and your browser keeps it for next visits.
- Look at the lines on your photo. The dashed line is the face length, with a guessed hairline at its top. The other lines are the forehead, cheekbones and jaw.
- Read the closest shape and the runner-up on the right. If they are close, the page says so.
- If a white point sits in the wrong place, drag it. The numbers and the shape update as you move it.
- Click Download the picture to save the photo with its lines and numbers, or Copy the result to paste the numbers somewhere.
What is measured
Everything is divided by the cheekbone width, so the size of the photo and the distance from the camera do not matter.
| Number | What it is | What it tells you |
|---|---|---|
| Length | Hairline guess to chin, divided by cheekbone width | Long and narrow, or short and wide |
| Jaw | Width across the jaw corners, divided by cheekbone width | Broad jaw or narrow jaw |
| Forehead | Width across the forehead sides, divided by cheekbone width | Wide forehead or narrow forehead |
| Chin angle | The angle at the chin between the two jaw corners | Pointed chin or flat chin |
A worked example: if the face is 580 pixels from hairline to chin and 400 pixels across the cheekbones, length is 580 ÷ 400 = 1.45. A jaw 320 pixels wide gives 320 ÷ 400 = 0.80, and a forehead 340 pixels wide gives 340 ÷ 400 = 0.85. Those three numbers are the typical oval row in the table, so that face reads as oval.
How the closest shape is chosen
Each shape has a row of typical numbers. The page works out how far your four numbers are from each row, with each number counted in its own steps (a jaw ratio moves in much smaller steps than a face length), and the smallest total wins. The second smallest is the runner-up. When the two are nearly tied, the page says it is a close call, because a small change in the photo can flip the answer. That is normal for faces between two shapes.
Take a photo that reads well
- Look straight into the lens with the head level. A turned head looks narrower and a tilted chin changes the length. The page warns you when it sees either.
- Pull hair back off the forehead and the sides of the face. Hair across the forehead moves the hairline.
- Keep the mouth closed and relaxed. An open mouth drops the jaw.
- Use soft, even light with no strong shadow down one side.
- Hold the camera at eye level, a little way back, so the face is not stretched by a wide lens up close.
A face shape detector for glasses
Many people look up their face shape to choose glasses frames. The notes under the picture give a short idea for frames and for a haircut for the shape you land on, and for the runner-up when it is close. Treat them as starting ideas. Frame size, colour and how a pair sits on your nose matter as much as the shape, so try them on. If you wear glasses, take them off for the photo: the frames can cover the points near your eyes and the temples.
What it cannot do
The hairline is not one of the 478 points, so the top of the face is a guess made with the thirds rule: the forehead is taken to be as tall as the nose. That makes the length the weakest number. If your hairline is higher or lower, or hair covers your forehead, drag the top point to where you think it should be. The model also smooths faces, so differences between people look smaller in the points than they do to the eye, and the typical numbers in the table are tuned to that.
The shapes are a convention from styling guides, not a scientific classification, and real faces sit between them. This page does not guess your age, does not score how attractive you are, and does not identify you. The model's own cards say the same about identification. It was made for augmented reality effects, so a photo in good light, facing the camera, is what it was built for.
To crop a photo to the face first, use the image cropper. To take a still with filters and a timer, try the online camera. To hide faces in a photo before you share it, use blur faces.
Questions
Good to know.
Is my photo uploaded?
No. The face model is downloaded to your browser and runs there, so the photo never leaves your computer. The camera picture is held in the tab only while you use it, and nothing is stored.
What does the first use download?
About 19 MB: the engine that runs the model (about 14.5 MB), the face model (about 3.8 MB) and some small scripts. Your browser normally keeps them, so later visits start faster. If you clear site data or use a private window, it downloads again.
How accurate is it?
It is a rough guide. The points on a clear, straight photo are placed well, but the shape names are a styling convention, and the top of the face is a guess. Treat the answer as a good starting point and look at the numbers and the lines, not only the name.
Why did my shape change between two photos?
Faces near the border of two shapes can flip with a small change: a slightly turned head, a lifted chin, a different smile or hair on the forehead. When the page shows a close call, read both shapes. Taking two or three straight photos and comparing them tells you more than one.
Does it work with glasses on?
Often, but take them off if you can. Frames can cover the points near the eyes and the temples and nudge the cheekbone and forehead points.
What if hair covers my forehead?
The hairline guess may be off, which changes the length. Pull the hair back and retake the photo, or drag the top point to where your hairline is.
Does it tell my age or how attractive I am?
No. It measures four proportions and names the closest shape. It gives no age, no score and no ranking, and it does not identify who you are.
Can I use it on a photo with several people?
It finds every face it can and shows you the largest first. Use the Face buttons above the photo to switch. For the cleanest read, crop the photo to one face.
Which browsers work?
A recent Chrome, Edge, Firefox or Safari. The model needs WebAssembly with SIMD, which current versions of these have. The camera needs your permission.
Is this a medical or identity tool?
No. It is a styling aid made from proportions, not a medical, identity or beauty test.
