Face Shape Detector — Oval, Round, Square?

Upload a front-facing photo. Landmark AI measures your proportions and names the shape — privately, in seconds.

How the call is made

  • Oval: length clearly exceeds width, balanced jaw and forehead.
  • Round: width and length close, soft angles throughout.
  • Square: jaw nearly as wide as cheekbones, compact length.
  • Heart: forehead wider than a tapering jaw.
  • Oblong: length far exceeds width at every measure.

Stylists use the same ratios for haircuts, glasses and beards — which is exactly why this page gets shared.
