Our detector identifies the five most common shapes; diamond and triangle have identify-by-hand guides.
What is a face shape detector?
A face shape detector is a tool that analyzes a photo of your face and tells you which face-shape category it best matches. Ours is powered by a proprietary AI model trained on labeled face photos: it recognizes your face shape directly from the image, rather than using the facial-landmark-and-ratio rules that many other tools rely on.
The model runs on our servers and returns your result in seconds. Your photo is used only to produce that result and is deleted immediately after analysis. It is never stored or used to train our model.
Our detector identifies the five most common face shapes: oval, round, square, oblong, and heart. Two closely related shapes (diamond and triangle) are less common; you can identify those by hand using the method below, and we cover them in full in the face shapes guide.
How to find your face shape in 3 steps
- Upload a clear, front-facing photo. Pull your hair back, look straight at the camera, and keep a neutral expression: no tilted head, and remove glasses. Even, front-on lighting gives the clearest result.
- Let the detector analyze your photo. Our AI model processes the image on our servers and identifies your face shape, returning the best match plus close alternatives if your face sits between two categories.
- Get your result and recommendations. You'll see your face shape, a short explanation, and links to the hairstyles and glasses widely recommended for that shape.
The face shapes
Face shapes are defined by the relationship between four measurements: forehead width, cheekbone width, jawline width, and face length. Here's the one-line version of each, with a link to the full guide. Our detector returns the first five; diamond and triangle are covered as identify-by-hand guides.
| Shape | Detected by tool? | Defining trait | Full guide |
|---|---|---|---|
| Oval | ✅ | Balanced proportions, length about 1.5× width, forehead slightly wider than jaw | Oval face shape |
| Round | ✅ | Length ≈ width, soft curves, no angular jaw | Round face shape |
| Square | ✅ | Forehead, cheekbones, and jaw are similar widths with a strong, angular jawline | Square face shape |
| Oblong (rectangle) | ✅ | Noticeably longer than wide, with fairly straight, parallel sides | Oblong face shape |
| Heart | ✅ | Wider forehead and cheekbones tapering to a narrow, pointed chin | Heart face shape |
| Diamond | Identify by hand | Narrow forehead and jaw with the cheekbones as the clear widest point | Diamond face shape |
| Triangle (pear) | Identify by hand | Jaw wider than the forehead; the inverted version is the reverse | Triangle face shape |

How it works and how accurate it is
Our detector is powered by a proprietary AI model trained on a large set of labeled face photos. Instead of measuring landmark distances the way rules-based tools do, it recognizes your face shape directly from the image and returns the best-matching shape, along with close alternatives when a face sits between two categories.
No photo-based tool is perfect, and we don't claim a magic number. Accuracy is best with a clear, straight-on photo, even lighting, hair off your face, a neutral expression, and no glasses; sharp angles, heavy shadows, or a face that genuinely blends two shapes can affect the result. We explain exactly how the tool works, and where its limits are, on the methodology page. Something most competing tools don't do.
Is it free and private?
Yes to both. The tool is completely free, with no account, email, or payment required to see your result. Your photo is uploaded only so the model can analyze it, and it is deleted immediately afterward: we don't store it, use it to train our model, or share it. If you share a result link, only the result is shared, not your photo. Full details are on our privacy page.
What can you do with your result?
Once you know your face shape, the next useful step is turning that into styling decisions:
- Hairstyles. See the cuts, lengths, and fringe styles most commonly recommended for your shape at Best Hairstyles for Every Face Shape.
- Glasses. Frame shapes that tend to balance your proportions are covered at Best Glasses for Your Face Shape.
- Deeper detail. Read the full breakdown (defining features, celebrities with the same shape, and shape-specific do's and don'ts) on your face shape's dedicated page.
Frequently asked questions
How can I identify my face shape?
Measure four widths (forehead, cheekbones, and jawline) and your face length from hairline to chin, then compare which is widest and how the length relates to the width. You can do this with a tape measure and mirror (see our step-by-step guide), or skip straight to the detector above for an instant, photo-based result across the five most common shapes.
Can AI or ChatGPT identify my face shape?
General-purpose AI chatbots can offer a rough guess from a description or photo, but they're built for general tasks and can be inconsistent between attempts. A purpose-built face shape detector like the one on this page uses a proprietary AI model trained specifically on labeled face photos, which gives more consistent results.
Is there an app that identifies my face shape?
Yes, both dedicated mobile apps and web-based tools exist. A web tool like ours has the advantage of no install and no account: you upload a photo, get a result in seconds, and your photo is deleted right after the analysis.
Are face shape detectors free?
Many are, including this one. Some free tools cap the number of scans, require sign-up, or add watermarks and upsells. Ours needs no account and deletes your photo immediately after analysis.
How accurate is a face shape detector?
Accuracy depends on photo quality (front-facing, neutral expression, hair off the face, no glasses) and on how closely your proportions match a single archetype. Many real faces are a blend of two shapes. For the most reliable result, use a clear, straight-on photo in even lighting.
