A face shape calculator should return a working label, the length and width ratios behind that label, and the nearest alternative. Upload one clear, front-facing photo; this face shape calculator measures forehead, cheekbone, jaw, and face length in your browser, then shows which shape the measurements support and what to retest.
The same browser tool can serve as a face type detector, free face shape detector, AI face shape detector, face shape detector app, face shape detection app, or face shape recognizer.

JPG, PNG, or WebP. Use one well-lit, front-facing photo at 600px or larger when possible. Keep your full hairline and jaw visible, use a natural expression, and avoid sunglasses or filters.
The answer is not the single label alone. The calculator first decides whether the face length reads short, balanced, or long; it then compares three widths, checks the width profile, and uses jaw shape as a tie-breaker. If the first result is close to another shape, keep both labels and change only one photo condition before retaking the measurement.
Keep the camera at eye level, the head straight, the expression relaxed, and the hairline and jaw visible. A tilted phone, strong side light, or cropped forehead changes the input before the calculator begins. The detector guide explains the photo conditions that make the readout usable.
H runs from the upper face to the chin. C is cheekbone width, F is forehead width, and J is jaw width. The calculator uses cheekbone width as the common reference, so the three visible ratios are H/C, F/C, and J/C. Averaged landmark pairs make one stray point less influential.
Start with H/C to place the result in a short, balanced, or long length family. Use F/C and J/C to find the dominant horizontal line. Then check the width profile and jaw angle. Starting with the jaw alone can make a long oval look square, while starting with length alone can hide a strong cheekbone or lower-face width.
A border result is useful evidence, not a calculation error. Treat the primary label as the best current description and the secondary label as the nearby hypothesis. Retake the photo at the same distance with one condition changed. If the pair stays together, use the mixed-result method instead of forcing one permanent category.
| Readout | What it answers | How to use it |
|---|---|---|
| Length ratio | Is the face shorter, balanced, or clearly longer than its cheekbone width? | Use it as the first filter. Do not let jaw styling advice override the length family. |
| Width balance | Do the forehead, cheekbones, or jaw dominate the horizontal profile? | Use the order to separate upper-heavy, cheek-led, and lower-heavy shapes. |
| Jaw angle | Does the lower outline read softer or more angular? | Use it to separate close pairs such as round versus square, not as the whole answer. |
| Nearest alternative | Which category remains plausible after the primary score? | Record both. Retake once when the result is close instead of treating the first label as fixed. |
| Photo quality | Did angle, exposure, size, cropping, or expression weaken the input? | Withhold the label when a blocking warning appears; use a warning note only as a reason to retest. |
The percentage shown with a result describes the strength of the rule match under this site's fixed model; it is not a probability that a stranger would choose the same word. For a second observation, compare the [face shape chart](/face-shape-chart) and keep the [face symmetry test](/face-symmetry-test) separate: symmetry checks whether paired features repeat, while this calculator compares overall length and width. The [eye shape detector](/eye-shape-detector) records lid opening, upper-lid structure, corner tilt, and spacing separately. The [golden ratio face test](/golden-ratio-face-test) shows how to lock a distance pair and calculation direction without turning the number into a beauty score.
Once the model returns facial landmarks, three pairs are averaged for each horizontal width. This reduces the effect of one unstable point.
H = d(10, 152)
C = avg cheekbone pairs
F = avg forehead pairs
J = avg jaw pairs
d(a, b) = sqrt((x_a - x_b)^2 + (y_a - y_b)^2)
Seven shape profiles are scored from length, width balance, and jaw angle. The highest score is shown with the nearest alternative.

A useful face shape quiz gives you a working label plus the measurements behind it. Upload one clear, front-facing photo, then check face length, forehead width, cheekbone width, and jaw width before treating the result as a styling starting point.
