FACE SHAPE DETECTOR APPS
Face shape detector apps compared: free, accurate and safe options
Face shape detectors mostly agree on the method; they differ in whether your photo leaves your phone, whether they show the close second shape, and what they help you do next.
QUICK ANSWER
A good face shape detector measures your face from a straight-on photo, shows the runner-up when two shapes are close, and tells you where your photo goes. Free options exist: FaceRater and faceshapedetector.app both measure in your browser without uploading the photo, YouCam’s web detector is free to try, and BeautyPlus offers five free tries a day. Facetune’s detector needs a subscription.
Find your face shape — freeHow does a face shape detector work?
A detector finds landmarks around your face, measures its length against its width and compares the widths of your forehead, cheekbones and jaw, plus the angle of the jaw. Those ratios decide the shape: a face clearly longer than wide reads oblong, a wide jaw with a sharp angle reads square, a narrow chin under wider cheekbones reads heart or diamond.
Many faces sit between two shapes, so the most useful detectors say so instead of forcing one label. The photo matters as much as the app: the camera at eye level, your head straight, hair off the forehead and jaw, and a neutral expression.

Are face shape detectors accurate?
They are as accurate as the photo and the landmarks. A slight head tilt, a smile or hair over the jaw can move a face from oval to round or square, which is why the same face can get different answers in different apps. Some tools publish an accuracy percentage; without knowing what it was tested against, treat that as marketing.
Two things help more than the app choice: take the photo straight on with your hair pulled back, and look at the measurements behind the label. FaceRater shows face length against cheek width and the widths of forehead and jaw, and names the second shape when it is close, so you can see why it chose the label.
- Camera at eye level, about an arm’s length away; no wide-angle selfie close-up.
- Hair off the forehead and away from the jaw.
- Neutral expression, mouth closed.
- Even light from the front.
- If two shapes are close, read the advice for both.
What to do with your face shape
The point of knowing your shape is choosing what frames it. Hairstyles change the outline most, glasses add lines at eye level, and brows set the angle of the upper face. A detector that leads straight into those choices saves you a second search.
Questions people ask
Is there a free face shape detector app?+
Yes. FaceRater and faceshapedetector.app are free in the browser with no sign-up, YouCam’s web detector is free to try, and BeautyPlus allows five free tries a day. Facetune’s detector needs a subscription.
What is the most accurate face shape detector?+
One that measures from a straight-on photo and shows its measurements and the close second shape. Accuracy depends more on the photo than on the app: camera at eye level, hair off the face, neutral expression.
Is a face shape detector safe?+
Check where the photo goes. FaceRater and faceshapedetector.app analyze it in your browser without uploading it; others process it on their servers under their privacy policies, and some keep photos to improve their algorithms.
How do I find my face shape on Facetune?+
Facetune offers a face shape detector inside its app for subscribers, with a free trial. If you don’t want a subscription, a free browser detector measures the same proportions.
Can a face shape detector tell which glasses suit me?+
Some can lead you there. FaceRater’s glasses finder uses the same measurements to list the frames to start with, the ones to use with care, and how wide your frames should be.
Does a face shape detector work for men?+
Yes. Face shapes don’t depend on gender. Men usually use the result for haircuts, beard shape and glasses.
Why do different apps give me different face shapes?+
They use different landmarks and cut-offs, and small changes in head angle or hair move the ratios. If you’re between two shapes, that’s normal: read the advice for both.
