Face shapes
These are styling buckets rather than scientific categories. Most faces sit somewhere between two of them, which is why the analysis reports a confidence band instead of a decimal percentage.
Oval
Slightly longer than wide, with the cheekbones as the widest point and a gently rounded jaw. The most forgiving shape — most cuts work, so the decision comes down to hair texture and how much effort you want to spend.
Round
Face length and width are close, with a soft jaw angle and full cheeks. Styles that add height on top and keep the sides tight will make the face read longer and more angular.
Square
Jaw, cheekbones and forehead are close in width, with a pronounced jaw angle. The structure is already strong, so the job is either to show it off or to soften its corners.
Rectangle
A square jaw on a longer face. Height on top works against you here; width, fringe and side volume bring the proportions back.
Heart
A wide forehead narrowing to a smaller chin. Fringe and side weight balance the top, while beard length adds the width the lower face lacks.
Diamond
Cheekbones dominate, with a narrower forehead and a narrow chin. Width at the brow and along the jaw evens the outline out.
Triangle
A jaw wider than the forehead. Volume and width on top restore the balance; anything that adds bulk at the jaw works against it.
