Face Shape Calculator
Find your face shape from four measurements — forehead width, cheekbone width, jawline width, and face length — in any single unit (cm or inches). Get the shape, your length-to-width ratio, and quick styling tips.
Example: with Forehead width 12 · Cheekbone width 13 · Jawline width 11.5 · Face length (hairline to chin) 17 · Jawline Rounded / soft → Face shape: Oval.
- Length-to-width ratio1.31 (length ÷ cheekbone width)
- Widest featureCheekbones
- Styling tipMost frames and cuts suit you; keep the natural balance.

Face shape is read from which of forehead, cheekbone, and jaw is widest and how face length compares to width — a geometric guide, not a measurement of beauty.
How the shape is decided
Four numbers do most of the work: forehead, cheekbone, and jaw widths tell you where the face is widest, and face length compared to cheekbone width tells you whether it reads long or round. When cheekbones are widest and the face is clearly longer than wide, it is oval; when the three widths are similar and length roughly matches width, it is round or square depending on how angular the jaw is. A widest-at-the-forehead face that tapers to a narrow chin is heart-shaped; widest at the jaw is a triangle.
Measure with a soft tape at the widest point of each feature and from hairline to the bottom of the chin, all in the same unit. Because faces are not perfectly symmetric, treat the result as the closest match rather than a hard label.
How it’s calculated
Widths compared with a 5% threshold: jaw widest → triangle; forehead widest and tapering to chin → heart; cheekbones clearly widest → diamond (with a pointed chin) or oval/oblong by length. When widths are within ~5%, length-to-width ratio decides: ≥ 1.5 oblong/rectangle, 1.25–1.49 oval, under 1.25 round or square by jaw angularity. Units cancel, so any consistent unit works.
A geometric approximation from four measurements and two style choices; faces are asymmetric and borderline cases can read as two shapes. This is a styling guide, not a medical or diagnostic tool.
Face shapes at a glance
| Shape | Key signature |
|---|---|
| Oval | Length clearly greater than width; cheekbones widest, gentle taper |
| Round | Length ≈ width; soft, curved jaw |
| Square | Length ≈ width; strong, angular jaw |
| Rectangle / Oblong | Length well over width; three widths similar |
| Heart | Forehead widest, narrow or pointed chin |
| Diamond | Cheekbones widest; narrower forehead and jaw, pointed chin |
| Triangle (pear) | Jawline widest, narrower forehead |
Common face-shape classification from forehead/cheek/jaw widths and length-to-width ratio.
Common mistakes
- Mixing units — measure all four in the same cm or inches or the ratio is meaningless.
- Measuring cheekbones too low; use the widest point just below the outer eye corners.
- Expecting one perfect label — many faces sit between two shapes.
- Reading the result as a judgment of looks; it only describes proportions for styling.
Frequently asked questions
How do I measure my face shape?
Use a soft tape to measure forehead width, cheekbone width, jawline width, and length from hairline to chin, all in the same unit. The tool compares which is widest and the length-to-width ratio to name the shape.
What is the ideal face shape?
There isn't one — oval is often called balanced only because most styles suit it. Every shape has flattering cuts and frames; the tool suggests a starting point, not a ranking.
Why did I get a different shape than I expected?
Small measuring differences, especially at the cheekbones, can flip borderline faces between oval, round, and diamond. Re-measure at the widest points and average a couple of tries.
Is this a medical assessment?
No. It is a styling estimate of proportions only. For questions about facial asymmetry, swelling, or changes over time, see a doctor or qualified professional rather than a shape tool.
