Jawline Shape Detector

A jawline shape detector uses AI facial landmark detection to measure the proportions of your lower face from a photo — including jaw width, chin taper, and jaw corner angle — and classifies it into a named jawline shape type. The classification is paired with personalised hairstyle, makeup, and skincare tips.

This tool classifies jawlines into six types: Square, Angular, Round, Oval, V-Shaped (pointed), and Soft. These cover the most distinct jaw proportions. Many people's jawlines fall near the boundary of two types, and the two sides are rarely perfectly symmetrical.

The ideal hairstyle depends on your jaw width, taper, and corner definition — layers grazing or below the jaw tend to soften square or round jawlines, while chin-length styles can add width to a V-shaped jaw. See the styling tips in your results for shape-specific recommendations.

A V-shaped (or pointed) jawline narrows sharply from wider jaw corners down to a narrow, pointed chin, creating a distinct "V" silhouette. It is often associated with a delicate, elegant lower-face profile.

No. All processing happens entirely in your browser using Google's MediaPipe Face Landmarker. Your photo never leaves your device and is not uploaded to any server.

Accuracy depends on photo quality. A clear, well-lit, front-facing photo with your jawline fully visible and a relaxed, neutral expression will give the most reliable result. Facial hair, hair covering the jaw, or extreme angles can affect the detected outline.

The tool uses jaw-region landmarks from the MediaPipe 478-point face mesh, including the jaw corner (gonion) points, lower-jaw points near the chin, the chin tip, and cheekbone reference points used to compute the jaw corner angle. All measurements are normalised against inter-ocular distance for consistency across camera distances.

The underlying bone structure of the jaw is largely fixed by adulthood, but soft tissue changes, weight fluctuations, muscle tone, and skin elasticity can all affect how defined or soft a jawline appears over time.

A square jawline has near-equal width from the jaw corner to the chin with minimal taper and very sharp corners. An angular jawline has a clearly visible corner too, but with more taper toward the chin — reading as chiselled rather than fully square.

Yes — jawline shape analysis applies equally to all genders. The classification types describe proportions, not style preferences, and the tips can be adapted for any grooming or styling context.

Jawline shape is one of the key components of overall face shape — alongside forehead width, cheekbone width, and face length. Pairing this detector with our face shape calculator gives a fuller picture for hairstyle and grooming decisions.
