Zee Online ToolsFace shape detector
Upload a front-facing photo and see which of six common face shapes it is closest to, with hairstyle and glasses tips. The photo is analysed in your browser and is never uploaded.
Quick answer: choose a straight-on photo with your hair back and a neutral expression. The tool measures four widths and lengths on your face and names the closest of six shapes: oval, round, square, heart, diamond or oblong.
Use a soft tape measure or string and a mirror. Measure in any unit; use the same unit for all four.

This is an estimate from simple proportions, not a professional assessment. Different angles and lighting can change the result, so try a couple of photos.
How the face shape detector works
The tool uses a face-landmark model that runs in your browser. It finds hundreds of points on your face, such as the chin, the edges of the cheekbones, the corners of the jaw and the sides of the forehead. From four of those points it measures:
- Face length: from the top of the forehead to the chin.
- Cheekbone width: across the widest part of the face.
- Jaw width: between the two corners of the jaw.
- Forehead width: across the sides of the forehead.
Those four numbers are turned into three ratios against the cheekbone width, and simple rules pick a shape. The lines drawn on your photo show exactly which measurements were used.
The rules behind each shape
The rules follow common styling guidelines. They are rules of thumb that we have not tuned on a labelled set of photos, so borderline faces can fall either way.
| Shape | Rule used |
|---|---|
| Oblong | Face length is at least 1.55 times the cheekbone width. |
| Round | Length is 1.25 times the cheekbone width or less, and the jaw is narrower than 85% of the cheekbone width. |
| Square | The jaw is at least 85% to 88% of the cheekbone width (depending on length), so jaw and cheekbones look similar. |
| Heart | For faces between those two lengths, the forehead is at least 12 percentage points wider than the jaw, relative to the cheekbones. |
| Diamond | The forehead is under 82% and the jaw under 75% of the cheekbone width, so the cheekbones are the widest point. |
| Oval | None of the above: balanced proportions with length a bit more than width. |
How to measure your face by hand
- Stand in front of a mirror with your hair pulled back from your face and use a soft tape measure or a piece of string and a ruler.
- Measure from the middle of your hairline to the tip of your chin: this is the face length.
- Measure across the widest part of your cheekbones, just below the outer corners of your eyes.
- Measure from one jaw corner to the other, below the ears.
- Measure across the forehead at the widest point, about halfway between your eyebrows and your hairline.
- Use the same unit for all four and enter them on the "Measure by hand" tab.
The six face shapes, with hair and glasses ideas
Oval face
Face length is a bit more than cheekbone width, with a gently rounded jaw. Proportions are fairly balanced.
Hair: Most cuts work. Side parts and layers keep the balance; very heavy fringes can shorten the face.
Glasses: Most frames suit an oval face. Frames about as wide as the widest part of your face look natural.
Round face
Length and cheekbone width are close, and the jaw is soft rather than angular.
Hair: Height at the crown and longer layers past the chin add length. Chin-length blunt bobs can add width.
Glasses: Angular or rectangular frames add definition; very round frames repeat the curves.
Square face
Forehead, cheekbones and jaw are close in width, with a strong, angular jaw.
Hair: Soft layers, waves and side-swept styles soften the jaw. Blunt cuts at jaw level emphasise it.
Glasses: Round or oval frames soften angles; boxy frames add to them.
Heart face
The forehead is noticeably wider than the jaw, tapering toward the chin.
Hair: Chin-length cuts and side-swept fringes balance a wider forehead; volume at the jawline helps.
Glasses: Frames that are wider at the bottom, or rimless styles, balance the narrower chin.
Diamond face
Cheekbones are the widest point, with a narrower forehead and jaw.
Hair: Fringes and volume at the forehead and chin balance wide cheekbones; avoid flattening the sides.
Glasses: Oval or cat-eye frames and rimless styles work with wide cheekbones.
Oblong face
The face is long compared with its width, with fairly straight sides.
Hair: Fringes, waves and volume at the sides reduce the look of length; very long, straight styles add to it.
Glasses: Deeper frames and wide styles add width; avoid very small narrow frames.
These are styling suggestions, not rules. Hair texture, features and personal taste matter as much as shape.
Tips for a reliable result
- Take the photo straight on, with your chin level and eyes to the camera.
- Pull your hair back so the forehead and the sides of your face are visible.
- Use even light, without strong shadows on one side.
- Stand a little back from the camera and zoom in, because a very close lens stretches the middle of the face.
- Keep a neutral expression. Smiling widens the cheeks and changes the jaw line.
Accuracy and privacy
Treat the result as a rough guide. The detection model finds landmarks accurately in most clear photos, but the step from four measurements to a named shape is a simple rule of thumb, and real faces often sit between two shapes. If you get different answers from different photos, use the shape that appears most often, or read the descriptions above and choose the one that matches best.
The detection model and its code are served from this site and run on your device. No image data is sent anywhere, and closing the tab clears the photo. See the privacy policy for details.

Frequently asked questions
How do I find my face shape?
Upload a front-facing photo, or measure the length of your face, the width across your cheekbones, your jaw and your forehead and enter them on the manual tab. The tool compares those proportions with common guidelines for six shapes.
Is my photo uploaded?
No. The face model runs inside your browser. The photo is not sent to any server and is not stored.
How accurate is it?
It is an estimate based on four measurements compared with common styling guidelines. Angle, lighting, hair and expression all affect the result, so treat it as a starting point, not a verdict.
What are the face shapes?
Oval, round, square, heart, diamond and oblong. Each is defined by how face length, cheekbone width, jaw width and forehead width compare.
Can I do it without a photo?
Yes. Use the "Measure by hand" tab and enter four measurements taken with a tape measure.
What kind of photo works best?
A front-facing photo with the whole face visible, hair pulled back from the forehead, a neutral expression, and even light.
Why did my result change with a different photo?
Tilting your head, a wide-angle lens close to the face, a smile or hair across the forehead all change the measurements slightly. Try two or three photos taken straight on, from a bit of distance.
