"What is my face shape?" sounds like a question with one answer, but ask three quizzes and you may get three. The reason is not that your face keeps changing. It is that face shape is judged from an outline in a photo, and photos change outlines. This guide shows how to take a photo that gives a fair answer, how to read the result from Oakgen's AI Face Shape Detector, how to sanity-check it yourself, and what to do when you land between two shapes.
Once you have a likely shape, the companion guide glasses and haircuts for your face shape covers what to do with it.
What "face shape" actually means
Face shape categories come from hairdressing and eyewear advice. They describe the overall outline of the face using a few comparisons:
- Length compared with width. Is the face noticeably longer than it is wide, or close to even?
- Forehead, cheekbones and jaw. Which of the three is widest, and which is narrowest?
- Jawline and chin. Is the jaw angular or soft? Is the chin pointed, square or rounded?
From those comparisons come the usual labels: oval, round, square, rectangle (oblong), heart, diamond and triangle (pear). They are conventions for styling advice, not scientific categories, and plenty of faces sit between two of them. That is normal, not a problem with your face or the tool.
Take a photo that shows your real outline
Most disagreements between results start with the photo. These steps matter more than which tool you use.
Stand back from the camera
Phone cameras held at arm's length or closer exaggerate whatever is nearest the lens. Researchers have modelled this "selfie effect" for nasal size in close-range photos (Ward et al., JAMA Facial Plastic Surgery, 2018). For face shape, the same perspective effect can make the middle of the face look larger relative to the jaw and ears. Ask someone else to take the photo from a few steps away and zoom in slightly, or prop the phone up and use a timer.
Face the camera straight on, at eye level
Tilting the head down tends to make the forehead look larger and the jaw narrower. Tilting it up tends to do the opposite. Turning slightly to one side hides one cheek and jaw. Keep your chin level and look straight into the lens with the camera at eye height.
Get hair off the outline
Pull hair back from your forehead, temples, ears and jaw with a band or clips. A fringe hides forehead width and shape; hair falling around the cheeks can make any face look longer and narrower.
Keep the jaw visible
Remove glasses. If you have a full beard, know that the tool can only see the outline the beard makes, not the jaw underneath, and the report will say confidence is lower.
Use even light and a neutral expression
Strong side light creates shadows that read as edges. A big smile widens the cheeks and changes the jaw. Face a window, keep your expression relaxed, and avoid heavy contouring makeup for this photo.

Run the analysis
Upload the photo to the AI Face Shape Detector. The optional context box is useful for two things: telling it which face to look at if there is more than one person, and saying what you are deciding, for example "choosing new glasses" or "thinking about a shorter haircut."
The report always comes back with the same six sections:
- Likely Face Shape. The closest common category.
- Visible Evidence. The proportions it used: length compared with width, which of forehead, cheekbones and jaw is widest, and the jaw and chin shape.
- Hairstyles That Usually Suit It. Practical options with a one-line reason each.
- Glasses Frames to Try. Frame shapes, using common names you can search for or preview.
- Other Possible Shapes. Up to two neighbouring categories, with what would tip it one way or the other.
- Confidence and Limitations. What in the photo made the estimate harder: angle, hair, beard, glasses, lens distortion, expression.
Read the evidence section first, not the label. The label is a summary. The evidence is what you can check.
Check the result yourself
You do not need a tape measure to sanity-check the report. Use the same photo, or a mirror, and ask the same questions the analyzer asked.
- Is your face clearly longer than it is wide? If yes, the likely candidates are oval, rectangle (oblong), heart or diamond. If length and width look close, round or square are more likely.
- Which is widest: forehead, cheekbones or jaw? Widest at the cheekbones points toward oval or diamond. Widest at the forehead with a narrower chin points toward heart. Widest at the jaw points toward triangle (pear). Roughly equal widths point toward square or rectangle.
- Is the jaw angular or soft? Angular corners suggest square or rectangle. A soft, curved jaw suggests round or oval.
If your answers match the report's evidence, you can rely on the label for styling decisions. If they do not, look at the Confidence and Limitations section: it often explains the mismatch, such as hair covering the temples or a slight head tilt.
When you land between two shapes
Many people do. Common pairs are oval and oblong, round and square, and heart and diamond. Here is how to handle it.
- Run two or three different photos. Same rules: front-facing, hair back, camera at eye level, a few steps away. If the same shape comes up most often, use it.
- Read "Other Possible Shapes." The report says what would push it toward each alternative, for example a softer jaw than it looks or a forehead wider than the hairline suggests.
- Use advice that suits both. Many hairstyle and frame suggestions overlap between neighbouring shapes. Start with the ones that appear in both.
- Test visually. The most reliable check is to see options on your own face. Preview frames with Glasses Try-On and haircuts with the Hairstyle Changer.
What the tool does not do
The face shape detector looks at an outline and suggests styling options. It does not:
- identify who you are or say who you look like;
- infer gender, ethnicity, age, health or weight;
- rate attractiveness or describe any shape as a flaw;
- take measurements. Proportions are described in relative terms, and the result is a visual estimate that can change between photos.
Your face shape is one input to a styling decision, alongside your hair texture, how much time you spend styling, your glasses prescription and what you like. No category is better than another.
Common photo problems and what they do to the result
| Problem | What it usually does | Fix |
|---|---|---|
| Selfie at arm's length | Centre of the face looks larger, jaw narrower | Have someone take it from a few steps away |
| Chin down | Forehead looks bigger, chin smaller | Keep the chin level, camera at eye height |
| Fringe or loose hair | Hides forehead width and temples | Pull hair back for this photo |
| Glasses on | Breaks the outline at the temples | Take them off |
| Big smile | Widens cheeks | Relaxed, neutral expression |
| Side light | Shadows read as edges | Face a window or soft light |

Frequently asked questions
Can AI tell my face shape from a selfie?
It can give a visual estimate from a clear, front-facing photo. Close-range selfies distort proportions, and hair, beards and glasses hide parts of the outline, so a photo taken from farther away with hair pulled back gives a more reliable estimate.
Why do face shape quizzes give me different answers?
Because many faces sit between two categories, and small changes in angle, expression and hair change how the outline looks. Compare the evidence across two or three photos rather than trusting one label.
What are the main face shapes?
The common categories used in hair and eyewear advice are oval, round, square, rectangle (also called oblong), heart, diamond and triangle (also called pear). They are styling conventions, not medical or scientific classes.
Does the face shape detector judge my appearance?
No. It only classifies the visible outline and suggests hairstyles and glasses frames. It does not identify you or infer gender, ethnicity, age, health or attractiveness, and no face shape is treated as better than another.
