What Is the Rarest Face Shape? All 6 Ranked with Data

Key Takeaways

• Diamond is the rarest face shape, at approximately 5% of the adult population.
• Heart is the second rarest at approximately 11%.
• Oval is the most common at 28%, followed by round at 24%.
• Rarity is determined by the probability of all required measurements aligning simultaneously — not by attractiveness or desirability.
• Face shape rarity varies by ethnicity, age, and sex. The data cited here reflects broad averages from facial anthropometry research (Farkas, 1994; Rhee et al., 2004).

What Is the Rarest Face Shape?

Diamond is the rarest face shape. Approximately 5% of adults have a diamond face — defined by cheekbones that are dramatically wider than both the forehead and the jaw, creating the four-pointed silhouette the name describes. The geometry required is strict: cheekbones must be the widest facial point by at least 15%, the forehead must be noticeably narrower than the cheekbones, and the chin must taper to a pointed or narrow tip. All three conditions simultaneously are statistically unusual.

Here is every face shape ranked from rarest to most common, with the population percentage and the geometric reason it is rare:

All 6 Face Shapes Ranked: Rarest to Most Common

1. Diamond — ~5% (Rarest)

Diamond requires three simultaneous geometric conditions: cheekbones significantly wider than the forehead, cheekbones significantly wider than the jaw, and a narrow-to-pointed chin. The probability of all three conditions occurring together in natural facial development is low. Additionally, the cheekbone-dominant structure requires specific cranial bone development that is ethnically skewed — diamond faces are more common in certain East Asian and Central Asian populations and less common in European and sub-Saharan populations.

Celebrity examples: Rihanna, Jennifer Lopez, Robert Pattinson, Zac Efron.

2. Heart — ~11%

Heart shape requires a wide forehead that is noticeably larger than the jaw (by 15% or more) and a narrow, somewhat pointed chin. This configuration — wide-top, narrow-bottom — occurs when cranial bone development produces a wider upper face than the jaw permits below. It is more commonly seen in women than men (female skulls tend toward wider cranial vaults relative to jaw width), explaining why heart face is sometimes described as a “typically feminine” shape.

Celebrity examples: Reese Witherspoon, Taylor Swift, Ryan Gosling, Ashton Kutcher.

3. Oblong — ~14%

Oblong requires a length-to-width ratio of 1.5:1 or above, with width consistency above 88% across forehead, cheekbones, and jaw. The high L/W ratio without the compensating cheekbone-taper that defines oval requires a specific skeletal configuration: long skull base, consistent jaw width, and relatively flat sides. This occurs in measurable frequency but does not represent the statistical norm.

Celebrity examples: Benedict Cumberbatch, Ben Affleck, Blake Lively, Sarah Jessica Parker.

4. Square — ~18%

Square requires strong jaw angularity (defined jaw corners), all three widths roughly equal, and L/W ratio of 1.05–1.20. The jaw structure needed — a gonial angle below approximately 120 degrees — occurs in a significant minority. Square faces are more common in men than women due to testosterone’s effect on jaw development during puberty. This shape is often described as “strong” or “chiselled.”

Celebrity examples: Brad Pitt, Henry Cavill, Angelina Jolie, Keira Knightley.

5. Round — ~24%

Round requires an L/W ratio near 1.0 with soft jaw edges and consistent full cheeks. This is the default configuration when no single feature dominates — the face is simply not elongated, not angular, and not dramatically wide anywhere. Its frequency reflects that this absence of extreme features is a common outcome of average facial development. Round faces often appear younger due to fuller cheek volume.

Celebrity examples: Channing Tatum, Ed Sheeran, Adele, and Selena Gomez.

6. Oval — ~28% (Most Common)

Oval is the most common face shape and the baseline against which others are often measured. It requires modest elongation (L/W 1.25–1.45) with cheekbones as the widest point — a configuration that emerges naturally from average skull proportions without extreme features in any direction. The mild taper from cheekbones to chin is the most common relationship between mid-face and lower face width, explaining oval’s frequency.

Celebrity examples: George Clooney, David Beckham, Lupita Nyong’o, Beyoncé.

Why Rarity Does Not Equal Attractiveness

This is the clarification every list of this kind needs. Face shape rarity is a statistical measure of geometric probability, not a hierarchy of attractiveness. Oval is the most common face shape — it is also consistently rated the most “versatile” for styling. Diamond is the rarest — it is also demanding to style because extreme cheekbone width requires specific frame and hairstyle choices to balance.

Research on facial attractiveness (Perrett et al., 1994; Grammer and Thornhill, 1994) finds that symmetry and proportional harmony are the primary predictors of attractiveness ratings, neither of which correlates with face shape rarity. An oblong face near the golden ratio (1.618 L/W) may be rated as more attractive than a diamond face with poor symmetry, regardless of their relative rarity.

The more useful lens is not rarity but styling compatibility: how well does your face shape lend itself to the hairstyles, glasses, and makeup choices you enjoy?

Frequently Asked Questions

What is the rarest face shape?

Diamond is the rarest face shape, at approximately 5% of the adult population. The geometry required — cheekbones dramatically wider than both a narrower forehead and a narrow jaw — is uncommon in natural facial development. Heart shape is the second rarest at approximately 11%.

Is the oblong face shape rare?

Oblong is the third rarest face shape at approximately 14% of adults. It is less common than round (24%) and oval (28%) but more common than heart (11%) and diamond (5%). Oblong faces are slightly more common in men than women and have a slight positive correlation with taller stature.

What is the most attractive face shape?

Attractiveness research does not identify a single “most attractive face shape.” Symmetry and proportional harmony — which can be present in any shape — are the primary attractiveness predictors. Oval faces are often described as the most versatile for styling. Oblong faces photograph particularly well due to their proximity to the golden ratio proportion. Attractiveness in practice depends on how well a person styles their specific shape, not which category the shape falls into.

What percentage of people have each face shape?

Based on facial anthropometry research: Oval ~28%, Round ~24%, Square ~18%, Oblong ~14%, Heart ~11%, Diamond ~5%. These percentages are averages across diverse populations. Individual ethnic groups show different distributions — for example, diamond is more common in certain East Asian populations; square is more common among Northern European males.

Is heart face shape rare?

A heart shaped face is the second-rarest, at approximately 11% of the population. It is more common in women than men due to the hormonal influence on jaw and cranial development. Women’s faces statistically tend toward wider foreheads relative to jaw width, the key geometric requirement for heart face shape.
