Length-to-width ratio. Face length (hairline to chin) divided by face width (widest cheek measurement). Oval faces sit at approximately 1.5; round faces sit close to 1.0; oblong faces sit above 1.6. This is the most diagnostic single ratio.
Forehead width over cheek width. A forehead wider than the cheekbones points toward a heart or oblong classification; a forehead narrower than the cheekbones points toward a diamond classification.
Jaw width over cheek width. A jaw wider than or equal to the cheekbones points toward a square or round classification; a noticeably narrower jaw points toward a heart or oval classification.
Chin angle and projection. A pointed chin (acute angle under 110 degrees) shifts the read toward heart or diamond; a flat chin angle (above 130 degrees) shifts toward square or oblong. The angle is measured at the soft-tissue chin tip.
Length 1.5 times width. Cheeks slightly wider than forehead and jaw. Soft, rounded jaw line. Considered the most flexible shape for hairstyles and framing choices.
Length close to width (1.0 to 1.2). Soft jaw angle. Cheeks are the widest point. Tends to read as youthful; hairstyle goal is usually to add visible length.
Length close to width with defined jaw angle. Forehead and jaw width similar. Reads as structured. Hair and beard goal is usually to soften the angles or lean into them.
Forehead wider than jaw. Pointed chin. Cheeks intermediate width. Hairstyle goal is usually to balance the wider top with width at the jaw line.
Narrow forehead, widest at the cheeks, narrow jaw. Pointed chin. Less common shape. Hairstyle goal is usually to widen the forehead and balance the cheek width.
Length more than 1.6 times width. Forehead, cheeks, and jaw similar width. Reads as long. Hairstyle goal is usually to add visible width and break vertical line.
Straight-on angle. Camera at eye level. Flat daylight without strong directional shadow. Hair pulled back off the forehead and ears. Neutral expression, lips closed, teeth not clenched. Plain wall behind you. No glasses, no hat. The four ratio measurements only work if the four input widths are visible. Hair across the forehead or jaw line is the most common cause of a misclassification on the first attempt.
If the confidence band on the first scan is under 70 percent, retake with hair clipped back and a straight-on angle. The calculator returns the same shape consistently when the input photo meets the criteria. The shape does not change between scans; only the confidence band does.
Four ratios. Six shapes. Hairstyle picks calibrated to your geometry.
