A "square" result from the analyzer is driven by one specific measurement: how little your jaw narrows as it approaches your chin. Here's exactly what that means and how to style it.
As with every result on this site, that measurement comes from a photo processed entirely on your device via MediaPipe's on-device model — it's never uploaded, stored, or seen by anyone but you. See the privacy policy for the full picture.
Square requires your length-to-width ratio to be at or below 1.25 (so your face isn't notably longer than wide — ruling out oval and oblong), no dominant heart/triangle/diamond width pattern, and a jaw-taper ratio above 0.82 — meaning the width of your jaw near the chin is at least 82% of the width at mid-jaw. In practical terms: your jawline stays strong and close to full width almost all the way to the chin, rather than curving inward, which reads as an angular, defined jaw.
This ratio compares two jaw-width measurements at slightly different heights: mid-jaw (landmark indices 172/397) and jaw-near-chin (176/400). A face with a sharply pointed or narrow chin has a much smaller near-chin width relative to mid-jaw — a low taper ratio. A face with a broad, squared-off jaw has those two widths close to equal — a high taper ratio, close to 1.0. The 0.82 cutoff is where the tool draws the line between "tapering" (round) and "not meaningfully tapering" (square).
Softer, layered cuts — especially those with volume or waves starting around cheekbone height — are commonly used to draw attention upward and away from a strong jawline. Side parts and soft fringes can break up a strong, straight hairline that would otherwise reinforce the jaw's angularity. Blunt, chin-length cuts that end right at the jawline tend to emphasize its width and squareness rather than softening it.
If you're curious why you got square instead of round, the length-to-width and overall width proportions are likely very similar between the two — the deciding factor is specifically the jaw-taper measurement. See the round face guide for the mirror-image explanation of what happens below the 0.82 threshold.
A strong jawline measured this way isn't a flaw to be corrected — plenty of style guidance for square faces is about complementing a defined jaw rather than hiding it (angular frames and geometric haircuts can look intentional and striking on a square face shape, not just the "soften it" options above). Treat the suggestions here as options, not rules.
Because this category hinges on a jaw measurement specifically, make sure your jawline is clearly visible — not covered by hair or hidden by camera angle — when you take your photo. See how to take a photo for an accurate result.
Is a square jaw the same as a "strong jaw" compliment? Informally, yes — this measurement is specifically capturing jaw width retention near the chin, which is what people typically mean by a strong or defined jawline.
Can facial hair affect this measurement? The landmark model detects skin-surface geometry; a beard that visually changes where your jawline appears to a human eye may also shift where the model places jaw-adjacent landmarks, depending on coverage and styling.
What if I'm right at the 0.82 boundary? You may see either square or round depending on the photo — see the accuracy page for why borderline results can shift between photos.
