| Face Shape | Length/Width Ratio | Widest Feature | Jawline Type | Flattering Glasses |
|---|---|---|---|---|
| Oval | 1.35 to 1.55 | Cheekbones | Softly curved | Most frames (Square, Aviator, Wayfarer) |
| Round | 1.00 to 1.20 | Cheekbones/Equal | Soft & circular | Rectangular, Square, Angular frames |
| Square | 1.00 to 1.25 | Equal (Forehead/Jaw) | Sharp & angular | Round, Oval, Cat-Eye frames |
| Heart | 1.30 to 1.50 | Forehead | Pointed / V-chin | Bottom-heavy, Round, Light frames |
| Diamond | 1.30 to 1.55 | Cheekbones | Narrow pointed chin | Browline, Cat-Eye, Oval frames |
| Oblong / Rectangle | > 1.55 | Equal / Forehead | Long & straight/square | Tall, Oversized, Square frames |
| Pear / Triangle | 1.20 to 1.45 | Jawline | Wide & prominent jaw | Browline, Cat-Eye, Top-heavy frames |
| Egg | 1.40 to 1.60 | Mid-Face | Gently narrow chin | Geometric & Square frames |
Complete Guide to Facial Morphometry, fWHR & Face Shape Analysis
Facial shape analysis is rooted in biological anthropometry, craniometry, and aesthetic proportions. Determining your face shape allows you to choose flattering glasses frames, haircuts, beard styles, and makeup contouring that enhance your natural facial harmony.

Vector illustration of the 4 fundamental facial measurement axes used to calculate facial ratios (FL / CW and fWHR).
1. The Mathematics of Facial Morphometry & fWHR
Craniometric analysis evaluates the geometric relationships between key facial landmarks: the Trichion (hairline), Nasion (bridge of nose), Bizygomatic width (cheekbone distance), Bigonial width (jawline width), and Gnathion (lowest point of chin).
2. Classification of the 7 Primary Face Shapes

- Oval Face Shape: Length-to-width ratio is approximately 1.4 to 1.5. Cheekbones are slightly wider than forehead and jawline, with a soft, gently rounded chin. Considered the baseline versatile shape.
- Round Face Shape: Length-to-width ratio is close to 1.0 to 1.15. Cheekbones and face length are almost equal in size, with soft rounded angles and a curved jawline.
- Square Face Shape: Length-to-width ratio is 1.0 to 1.25. Forehead, cheekbones, and jawline are equal in width, characterized by a strong, sharp, angular gonial jaw angle.
- Heart Face Shape: Forehead is the widest feature, tapering down to high cheekbones and a narrow, pointed V-shape chin.
- Diamond Face Shape: Cheekbones are the prominent widest point, with a narrow forehead and narrow pointed chin.
- Oblong / Rectangle Face Shape: Length-to-width ratio is greater than 1.55. Long, narrow face structure with equal forehead and jaw widths.
- Pear / Triangle Face Shape: Jawline is the widest point, tapering up to narrower cheekbones and a narrow forehead.
3. How to Measure Your Face Accurately at Home
- Use a flexible tape measure or ruler while looking straight into a mirror.
- Forehead Width: Measure across the widest part of your forehead, from hairline to hairline above the eyebrows.
- Cheekbone Width: Measure across the peak of your cheekbones, from outer corner of one eye to the other.
- Jawline Width: Measure from the base of your jaw under your ear to the tip of your chin, then multiply by 2.
- Face Length: Measure vertically from the center of your top hairline (Trichion) down to the bottom tip of your chin (Gnathion).

Frequently Asked Questions
The Diamond face shape is considered the rarest face shape, characterized by high, wide cheekbones combined with a narrow forehead and narrow pointed chin.
Yes. While underlying bone structure (zygomatic and mandibulary bone width) remains constant, subcutaneous fat loss around the cheeks and jawline can reveal more defined angles, shifting a face from appearing round to oval or square.
Square, rectangular, and angular frames look best on round faces because their sharp lines contrast with soft facial curves, creating a longer, slimmer appearance.
fWHR (Facial Width-to-Height Ratio) is the ratio of cheekbone width to upper face height. In anthropology, higher fWHR values (greater relative width) correlate with testosterone exposure and masculine craniofacial development.
