Understanding face-shape detection
What does it mean to detect your face shape?
Face-shape detection compares the visible proportions of the upper face, cheekbones, jaw, chin, and overall length with six practical geometric profiles: oval, round, square, heart, diamond, and oblong.
Measurements considered
- Face length compared with face width
- Relative cheekbone width
- Upper-face and temple width
- Jaw width and taper
- Visible chin structure
- Balance between the upper and lower face
Why one clear photo can help
A front-facing photo provides a consistent reference for estimating proportions. Even lighting, a neutral expression, and a clear view of the cheeks, jaw, chin, and upper face improve the estimate.
Why two matches can appear
Real faces often combine traits from more than one profile. A secondary match shows the next-closest geometry and can make styling guidance more useful.
Transparent methodology
How our face shape detector works
Your photo is measured privately in your browser with Google MediaPipe Face Landmarker. No photo-analysis API, account, or image upload is required.
Map 478 landmarks
MediaPipe maps a normalized 3D face mesh. Quality checks reject unclear, tilted, off-center, or multi-person photos.
Measure proportions
Selected landmarks estimate face length and the relative widths of the temples, cheekbones, jaw, and chin.
Compare geometric profiles
Transparent rules compare those ratios with Oval, Round, Square, Heart, Diamond, and Oblong profiles.
What the match score means
Each percentage describes how closely the measured ratios fit a geometric profile. It is not model accuracy, identity recognition, a medical assessment, or a calibrated probability.
Known limitations
Results are 2D estimates. Camera angle, expression, hair, accessories, and lighting can affect them, and Face Landmarker does not directly identify the true hairline. Use a clear, front-facing photo for the best result.
The ratio calculations and input checks are covered by automated tests. The classifier has not yet been benchmarked against an independently labeled demographic dataset, so we do not publish an accuracy percentage.

Detect Face Shape: Explore types of Face Shape
Discover the unique characteristics of different face shapes and learn what styles complement your natural structure best.
1. Oval Face
Balanced & Versatile
Oval faces are slightly longer than wide, with softly rounded edges. Known as the most versatile shape, it complements a wide range of hairstyles and accessories.
2. Round Face
Soft & Youthful
Round faces have full cheeks and a softer jawline. This shape often gives a youthful and approachable look.
3. Square Face
Strong & Defined
Square faces are marked by a broad forehead and a strong jawline, giving a bold and confident appearance.
4. Heart Face
Charming & Distinctive
Heart-shaped faces feature a wider forehead that narrows toward the chin, creating a naturally attractive outline.
5. Diamond Face
Sharp & Elegant
Diamond faces are widest at the cheekbones with a narrow forehead and chin, giving a refined, angular look.
6. Oblong Face
Long & Refined
Oblong faces are longer than they are wide, with straight sides and a defined structure. This shape often carries a sophisticated feel.
Proportion reference
Face-shape comparison guide
Compare the overall length, widest visible area, and jawline together. No single feature determines face shape on its own.
| Face shape | Overall proportion | Widest visible area | Jawline and chin |
|---|---|---|---|
| Oval | Moderately longer than wide | Cheekbones often slightly widest | Softly tapered jaw without strong corners |
| Round | Length and width are relatively close | Cheek area often widest | Soft, rounded jaw and chin |
| Square | Length and width may be relatively close | Upper face, cheeks, and jaw have similar widths | Broad, angular jaw |
| Heart | Balanced or slightly longer than wide | Upper face wider than jaw | Jaw narrows toward a smaller chin |
| Diamond | Usually longer than wide | Cheekbones are the widest area | Narrower upper face and tapered chin |
| Oblong | Noticeably longer than wide | Upper face, cheeks, and jaw have similar widths | Straighter sides and a longer-looking chin |
Why manual comparison can differ
Hair, facial hair, makeup, camera angle, expression, and lighting can change how proportions appear. The detector evaluates several relationships together, but the result remains a styling estimate.
Mixed results are normal
When two profiles receive close scores, use both as styling references.
- Oval balance with oblong length
- Round cheeks with a more defined square jaw
- A heart-shaped taper with diamond-like cheekbones
- Square upper-face proportions with a softer oval chin

Frequently Asked Questions
How do I detect my face shape online?
Use a clear, front-facing photo with the cheeks, jawline, chin, and upper face visible. The detector maps facial landmarks and compares the proportions with six face-shape profiles.
How does the face shape detector work?
Google MediaPipe Face Landmarker maps 478 points on the visible face. Selected points estimate facial proportions, which transparent rules compare with oval, round, square, heart, diamond, and oblong profiles.
Is this an AI face shape detector?
It uses a machine-learning facial landmark model to locate points, then applies geometric measurements and comparison rules. It does not use generative AI to identify who you are.
How accurate is online face shape detection?
The same geometric rules are applied to every suitable photo, but the result remains an estimate. Angle, lighting, expression, hair, accessories, and lens distortion can affect it; the classifier has not been independently benchmarked on a large labeled demographic dataset.
What is the best photo for face shape analysis?
Use a sharp front-facing photo at about eye level, with a relaxed expression and even lighting. Avoid group photos, side profiles, filters, extreme angles, and anything that covers the facial outline.
Is my photo uploaded to a server?
No. The photo is processed locally in your browser and is not sent to our photo-analysis server, saved to an account, or added to a database.
Which face shapes can the tool identify?
The tool compares six profiles: oval, round, square, heart, diamond, and oblong. It can show a secondary match when your proportions share traits with more than one profile.
Why did the face shape finder show two matches?
Human faces do not fit perfectly separated categories. Two close matches mean some proportions resemble one profile while other features resemble another.
Does the face shape analyzer work for everyone?
The six geometric profiles can be used by people of any gender. The analysis uses visible proportions and does not need to determine or predict gender, identity, ethnicity, or attractiveness.
Is the online face shape detector free?
Yes. You can use it without payment, subscription, or account. No contact or payment details are required to analyze a photo.
Can I detect my face shape on a phone?
Yes. Open the tool in a modern mobile browser and choose a clear front-facing photo. The image analysis still runs locally on your device.
Is face shape a scientific or medical diagnosis?
No. Face-shape labels are broad geometric categories used for styling guidance. They do not diagnose health, identify a person, measure attractiveness, or define how someone should look.
