Face shape guides
Face shape is a description of bone-structure proportions. It is useful for one specific job: knowing where a hairstyle, a pair of glasses or a beard will add width, and where it will add length. It is not a ranking, and it does not describe how anyone looks.
Each guide below covers the proportions that define the shape, how to check it with a tape measure, and what to do with the answer. If you would rather not measure anything, theface shape detector does the measuring in your browser.
Where the six shapes differ
Every shape comes down to two questions: how long the face is relative to its width, and which of the three widths — forehead, cheekbones, jaw — is the largest.
| Shape | Length ÷ width | Widest point |
|---|---|---|
| Oval | Face length ≈ 1.5 × cheekbone width · cheekbones are the widest point · forehead slightly wider than a gently tapered jaw. | Length is about one and a half times the width — clearly longer than round, shorter than oblong. |
| Round | Face length ≈ width (ratio near 1.0–1.25) · forehead, cheekbones and jaw all about the same width · the jawline has no hard corner. | Length and width are close: the length-to-width ratio is usually 1.0–1.25. |
| Square | Face length ≈ width · forehead, cheekbones and jaw within a few percent of each other · a hard angle at the jaw and often a straight hairline. | Length and width are close, similar to a round face. |
| Heart | Forehead wider than cheekbones, cheekbones wider than jaw · a sharp chin point · F > C > J in the three width measurements. | The forehead is the widest of the three widths — the opposite of diamond. |
| Oblong | Face length ÷ width is above about 1.6, with the forehead, cheekbones and jaw at similar widths and minimal tapering. | The length-to-width ratio is the largest of any shape — typically 1.6 or higher. |
| Diamond | Cheekbones wider than both the forehead and the jaw · forehead and jaw are of similar, smaller width · C > F and C > J. | The cheekbones are the widest point of the face. |
The guides
- Oval face shape — The balanced reference shape: slightly longer than wide, cheekbones the widest point, and a jawline that curves rather than angles.
- Round face shape — Roughly as wide as it is long, with full cheeks and a soft, rounded jawline — curves everywhere and no hard angles.
- Square face shape — Compact proportions like round, but with a defined jaw corner and minimal taper — forehead, cheekbones and jaw are all about the same width.
- Heart face shape (inverted triangle) — The forehead is the widest point of the face, tapering through high cheekbones to a narrow, often pointed chin.
- Oblong face shape (long face) — Clearly longer than wide with fairly parallel sides — the forehead, cheekbones and jaw are all at similar widths, just stretched vertically.
- Diamond face shape — The cheekbones are the widest point, with the face narrowing towards both a narrower forehead and a narrower jaw — a double taper.
Common questions
How many face shapes are there?
Most charts use six or seven categories. Six — oval, round, square, heart, oblong and diamond — cover the proportions this tool measures. Some charts add a seventh, triangle, for a jaw that is wider than the forehead.
Can you have two face shapes?
Yes, and many people do. The categories are regions on a continuous space of proportions, not distinct boxes, so a face can sit between oval and oblong, or between square and round. That is why this tool always shows the runner-up shape alongside the result.
Does face shape determine what looks good on you?
It is one input, not a verdict. Face shape tells you where a hairstyle or a frame will add width, and where it will add length. Expression, grooming, lighting and camera angle all change how a face reads, often more than the underlying proportions do.
How do I measure my face shape without a photo?
Stand in front of a mirror with a tape measure. Measure hairline to chin (L), across your cheekbones (W), your forehead (F) and your jaw (J). The ratio L÷W sorts long faces from compact ones, and comparing F with J and W tells you where your face is widest.
These guides describe proportions and styling, not attractiveness. If a shape is listed here as "avoid", it means it works against the geometry — not that it looks bad.
