Face shape is a description of facial proportions, often used to choose hairstyles, glasses and makeup. This calculator compares four measurements — forehead width, cheekbone width, jawline width and face length — and reports the closest common shape. The result is a style guide, not a scientific classification.
Classify face shape from four facial measurements.
Ratios: length ÷ cheek, forehead ÷ cheek, jaw ÷ cheek Oblong: length/cheek > 1.5 Round/square: widths within 6% of each other Heart: forehead > jaw by >10% Diamond: cheek widest by >8% Triangle: jaw > forehead by >10% Otherwise oval
There is no medical standard for face-shape categories. The thresholds here are a transparent heuristic for styling. Small differences near a boundary can change the label, so use the result as a guide.
| Symbol | Meaning |
|---|---|
| Face length | Hairline to the bottom of the chin. |
| Forehead | Widest forehead width. |
| Cheek | Widest cheekbone width. |
| Jaw | Widest jawline width. |
Length ÷ cheek = 1.40, so the face is not oblong. The cheek is the widest point and exceeds the forehead by about 7%, which sits near the diamond boundary. The jaw is narrower than the forehead. This combination is usually read as oval or diamond; the calculator picks the closest rule.
Face-shape advice exists to solve practical problems: which glasses frame a face without overwhelming it, which haircut adds width or length, where to place contour. The categories are shorthand for a set of proportions, not fixed types. A strong jaw and wide cheekbones can read as square in one photo and oval in another depending on lens, lighting and expression. Phone cameras also distort facial proportions when held close. If you are using the result to choose glasses, try frames in person and pay attention to width and bridge fit rather than the label. For hair, the most useful measurements are where your face is widest and how long it is relative to width. Those two facts do more work than the name of the shape.

Bone structure is stable in adults, but weight change, ageing, dental work and hairstyle can alter how proportions look. The underlying measurements usually change little.
Every result is a screening estimate from published anthropometric equations, not a diagnosis or a measurement of body composition. Tape measurements should be taken snugly against the skin without compressing it, at the landmarks named in each tool. Equations were derived in specific populations and can be less accurate for athletes, older adults, children, pregnant people and people with significant oedema.
