What Is a Triangle Face Shape?
A triangle face is the inverse of heart: the jaw is the widest point, the forehead the narrowest, and the outline broadens steadily from top to bottom. It is sometimes called pear-shaped.
How to Tell If You Have a Triangle Face
- 1
Compare jaw and forehead
On a triangle face the jaw measures clearly wider than the forehead. Every other shape has the jaw equal to or narrower than the forehead.
- 2
Check the cheekbones
The cheekbones sit between the two widths rather than being the peak, which separates triangle from diamond.
- 3
Look at the jawline
The jawline is broad and often angular, carrying most of the face's visual weight at the bottom.
Triangle Face Measurements
Typical range = our published prototype value ± one standard deviation, from the same rule set the detector runs on.
| Feature | What it is | Typical for triangle |
|---|---|---|
| Face length ratio | face length ÷ cheekbone width | 1.18 – 1.42 |
| Forehead ratio | forehead width ÷ cheekbone width | 0.73 – 0.87 |
| Jaw ratio | jaw width ÷ cheekbone width | 1.01 – 1.15 |
| Jaw angle | angle at the jaw corner | 110° – 126° |
| Chin taper | chin width ÷ jaw width | 0.42 – 0.58 |
Best Glasses for a Triangle Face
Frames with emphasis on the top half — strong brows, upswept corners, extra width — pull attention upward and balance a jaw that dominates.
