Have four measurements? Calculate from numbers ↗
Want to adjust the points?
Your automatic result needs no edits. If a point looks misplaced, you can adjust it here. Only move the top point to your hairline when that hairline is clearly visible.
Tap the center of your visible hairline. Do not guess a hairline hidden by hair.
These are custom shape-match scores, not accuracy percentages. Your result is a styling starting point, not a rule about your appearance.
Your downloaded card contains scores, not your photo.

Calculate from four measurements
Use this if you already have your numbers. Keep all four in the same unit: centimeters, inches, or distances from one photo. Do not mix a tape length with a photo width. Jaw width means the straight distance between the two jaw corners, not a tape curved around the chin.
These are custom profile-match scores, not accuracy percentages. They do not add up to 100. A close pair is a useful result too.

What each number means
- Length: center hairline to the bottom of the chin. Keep the head level. A hidden or receding hairline makes this convention harder to repeat.
- Forehead: the visible width across the upper face near the temples. Hair should not stand in for the skin edge.
- Cheekbones: the width across the outer cheekbone area. Do not measure ear to ear.
- Jaw: a straight corner-to-corner width below the cheeks. Do not follow the curve around the chin.
A flat, front-facing photo makes straight widths easier to compare. A flexible tape resting on curved skin follows a different path, so it may disagree with a photo measurement.
How to read the ratio
Face length divided by cheekbone width gives a length-to-width ratio. For example, 19 ÷ 14 is about 1.36. Changing both numbers to the same other unit keeps that ratio the same.
1.36 alone does not identify a shape. The forehead and jaw widths, the outline, and our profile rules also matter. We do not use a single ratio as proof of oval, heart or any other label.
The photo mode measures pixels from a resized image. Those numbers cannot tell you your face size in inches or centimeters without a physical reference.
Read the measurement guide or learn what the shape names mean.
Why the photo and your numbers can differ
The two modes share the same comparison rules, but they may start with different measurements. Photo mode estimates the upper face boundary and the jaw outline. Your own measurements may use the visible hairline and a jaw choice you supply.
Check the measurement locations first. Next, check units and whether the jaw width is straight. Then compare a second level, unfiltered photo. If two shapes remain close, read both guides instead of chasing one perfect label.
This calculator does not measure the golden ratio, facial symmetry, midface ratio or facial width-to-height ratio used in research. Those are different questions with different measurement points. For phi comparisons, use the golden ratio calculator.
Keep it simple.
Follow the photo checklist before your first scan.
- Face the camera. Keep both eyes level and your mouth relaxed.
- Show your outline. Move hair back. Keep your chin and hairline visible.
- Use soft light. Avoid filters, strong shadows and blurry photos.
- Give yourself room. Avoid very close wide-angle selfies. Keep your face clear in the frame.
No need to mark points or enter measurements. If the result seems off, try a clearer photo. An optional photo editor is available after your result.

01. Find the points
MediaPipe automatically estimates face landmarks. Our code uses those points to estimate the face outline and measurements. No manual input is needed for an automatic result.
02. Compare the distances
We compare face length, forehead width and jaw width with cheekbone width. The automatically estimated jaw outline adds another clue. The math uses this flat photo, not a 3D scan.
03. Show the closest fits
Our own rules compare eight shape profiles. Scores describe how closely your inputs fit those rules. They are not probabilities and do not add up to 100.
No universal cutoff. Face-shape categories overlap. These rules have not been validated on a large labeled population dataset. We do not promise an accuracy percentage or judge beauty, health, gender or ethnicity.
See the scoring rules and limitations
With the automatic jaw estimate (or an optional user correction), the score is 100 × lengthFit^0.42 × widthFit^0.38 × jawFit^0.20. If you choose “Not sure”, jaw fit is left out and the other weights become 0.525 and 0.475. Each fit is floored at 0.01. Distances outside a range reduce fit smoothly; they do not trigger a hard diagnosis.
Length fit uses a Gaussian falloff with scale 0.14. Width fit averages three profile-specific checks with scales 0.06–0.08. Automatic jaw tone averages two normalized lower-jaw width ratios, producing a value from 0 to 1. It is compared with custom reference values: angular 1, soft 0.55 and pointed 0.10, using scale 0.32. Optional user jaw choices use those reference values directly. These settings are design choices, not scientific constants. A gap below 8 score points is described as a close match; a best score below 55 is described as a weak fit.
| Shape | Range | Main clue |
|---|---|---|
| Oval | 1.30–1.50 | Cheeks lead; soft taper |
| Round | 1.00–1.25 | Similar widths; softer jaw |
| Square | 1.00–1.28 | Similar widths; angular jaw |
| Oblong | 1.48–2.05 | Long; relatively steady widths; soft jaw |
| Rectangle | 1.48–2.05 | Long; relatively steady widths; angular jaw |
| Heart | 1.25–1.55 | Upper face wider than jaw; pointed taper |
| Diamond | 1.30–1.60 | Cheeks wider than forehead and jaw |
| Triangle | 1.15–1.55 | Jaw wider than upper face |
Automatic length estimate: the upper boundary extends the landmark-10-to-chin line by a factor of 1.06. This is our fixed geometric approximation, not AI detection of your true hairline or a validated anatomical correction. Jaw tone uses widths 150–379 and 176–400 divided by width 172–397, normalized with (taper − 0.55) / 0.25 and (chin ratio − 0.26) / 0.22, clipped to 0–1 and averaged. These are heuristics, not measured accuracy. You can optionally correct points; photo and tape measurements can differ.
Different sites combine or separate categories differently. Here, rectangle and oblong differ mainly by jaw outline; triangle means a wider jaw, not a wider forehead. Hair, facial hair, expression, lens distortion, age-related changes and point placement can all affect visible proportions. Photo distances are not physical measurements.
Read Google's landmark documentation ↗. It documents landmark detection, not validation of our shape rules. The face shape detector uses the same photo method. This calculator also lets you enter measurements; different input methods can produce different estimates.

Simple answers about your photo, your result and what this tool can do.
How do I find my face shape from a photo?
Choose one clear, front-facing photo or take one with your camera. Analysis starts automatically and shows your closest shapes. You do not need a ruler, point placement or a jaw selection. The optional editor is only for people who want to inspect or correct the estimate.
Is this face shape detector accurate?
It gives an estimate based on the landmarks and outline found in your photo. A tilted camera, hidden hairline or misplaced point can change the result. We have not established a validated accuracy percentage. Check the visible measurements and compare your top two shapes.
Is my photo uploaded or saved?
This widget processes photos, camera frames and points inside your browser. It does not send them to an analysis server, analytics or a shared-result URL. Remove your photo or reload to clear the active image. A result card is saved to your device only when you ask; it contains no photo. The model loads from Google storage and code loads from jsDelivr; those providers receive ordinary requests, including your IP address. MediaPipe also sends Google performance and usage metrics. Google states that input images and video are not sent with those metrics. Photo analysis starts only after you agree above. The site also uses Google Analytics; see our privacy policy for site-wide data practices.
Do I need to mark my hairline or measure my face?
No. The normal flow is automatic. The model estimates facial landmarks; our code approximates the upper face boundary because the true hairline is not reliably detected. That approximation can affect the result. If you want to, you can correct the points after seeing your result.
Why do I get two close shapes?
Shape labels overlap, and real faces often share features. A small score gap means our rules do not strongly separate the two. Read both guides. Try another straight-on photo if the result surprises you. Optional corrections can help you inspect what changed.
What if the photo or camera does not work?
Use a JPG, PNG or WebP under 10 MB. Export HEIC photos to JPG first. Allow camera access if you want to take a photo here. If the model cannot load, try automatic analysis again or choose another photo. An optional point editor is available, as is the manual calculator. Use one face per image.
Can I use this without a photo?
Yes. Use the four-number calculator on this page. It needs no photo, model download or photo-analysis consent. Keep all measurements in the same unit.
Does it work for men and women?
The same geometric rules are used for everyone. The tool does not identify gender and has not been validated separately for every demographic group. Facial hair and hair covering the outline can make a photo harder to measure.
Is it free? Do I need an app?
It is free and needs no account or app installation. A modern browser with JavaScript is needed. Photo analysis downloads a face model on first use, so the first attempt may take longer on a slow connection.
