How the calculator works
Enter your four measurements. We calculate three ratios: face length to cheekbone width (D/B), forehead to cheekbones (A/B) and jaw to cheekbones (C/B). Each face shape has a typical range for all three; your face scores by how close it sits to the centre of each range, and the shape with the closest overall match is your result.
The ranges are editorial guidelines drawn from common styling practice, not a medical classification. Real faces sit between shapes, which is why the full ranking is shown.
| Face shape | A/B (forehead) | C/B (jaw) | D/B (length) |
|---|---|---|---|
| Oval | 0.88 – 1.00 | 0.75 – 0.88 | 1.30 – 1.50 |
| Round | 0.86 – 0.98 | 0.80 – 0.92 | 1.10 – 1.30 |
| Square | 0.92 – 1.04 | 0.90 – 1.00 | 1.10 – 1.30 |
| Oblong | 0.90 – 1.02 | 0.85 – 1.00 | 1.50 – 1.75 |
| Heart | 1.00 – 1.12 | 0.65 – 0.80 | 1.25 – 1.50 |

Questions people ask
How accurate is a face shape calculator?
As accurate as your measurements. The ratios are compared with typical ranges for each shape, and the full ranking shows how close the call is. A margin under ten points means you share traits of two shapes.
Can I use inches?
Yes. The calculator only uses ratios between your measurements, so any unit works as long as all four use the same one.
