Sydney Sweeney PSL Score & Neoteny Breakdown
Sydney Sweeney is a useful modern reference because her PSL profile is driven almost entirely by neoteny rather than bone. Large palpebral fissures with high vertical eye opening, a smooth brow contour, full cheeks and a short philtrum score 6.9 on Feminine Dimorphism, while a softer gonial corner and lower-third fullness keep Angularity at 5.6. The result is a 6.3 Stacy score that reads far higher in everyday appeal than strict PSL suggests. Measure your own eye aspect ratio and PSL pillars with the free PSL score calculator →
Sydney Sweeney's 4-Pillar PSL Scorecard (6.3 / 8.0)
Sydney Sweeney places in the Stacy tier (Top 0.3%, roughly 8.9 / 10 on a conventional 1-to-10 scale). Below is how Sydney Sweeney's craniofacial structure grades across the four weighted PSL pillars:
| PSL Pillar | Weight | Sydney Sweeney's Score | Population Mean | Primary Anatomical Driver |
|---|---|---|---|---|
| Facial Harmony | 35% | 6.4 / 8.0 | 4.0 / 8.0 | Midface ratio, vertical thirds & interocular spacing (ESR) |
| Sexual Dimorphism | 25% | 6.9 / 8.0 | 4.0 / 8.0 | Supraorbital rim, bigonial width & lip-to-philtrum balance |
| Bone Angularity | 25% | 5.6 / 8.0 | 4.0 / 8.0 | Zygomatic arch projection, gonial angle & submalar hollow |
| Miscellaneous / Soft Tissue | 15% | 6.5 / 8.0 | 4.0 / 8.0 | Hair framing, brow density, lash contrast & skin clarity |
Sydney Sweeney's Craniofacial Ratios (fWHR, Canthal Tilt & Gonial Angle)
Unlike subjective 1-to-10 ratings, PSL anthropometry measures scale-invariant distances and angles between facial landmarks. Here are Sydney Sweeney's key craniofacial ratios compared against the adult population average:
| Craniofacial Metric | Sydney Sweeney | Population Mean | Structural Read |
|---|---|---|---|
| Eye Aspect Ratio (Palpebral Fissure) | 2.65x | 2.80x - 3.20x | Large vertical opening, rounded almond shape |
| Feminine Dimorphism Pillar | 6.9 / 8.0 | 4.0 / 8.0 | Strong neoteny: smooth brow, full cheeks, short philtrum |
| Angularity Pillar | 5.6 / 8.0 | 4.0 / 8.0 | Soft gonial corner and lower-third fullness |
| Chin-to-Philtrum Ratio | 2.20x | 2.00x - 2.20x | Short upper lip height |
| Canthal Tilt | +2.5° | +1.5° - +3.0° | Neutral-positive, rounded rather than feline |
Primary Facial Halos (Neotenous Stacy: Large Palpebral Fissures & Soft Lower Third)
A facial halo is a high-leverage craniofacial feature that elevates the entire face's first impression. Sydney Sweeney's signature halos are:
Large, high-opening palpebral fissures
A low eye aspect ratio (wide vertical opening) is the single strongest neoteny cue and reads as warmth and approachability.
Smooth supraorbital contour and full upper cheeks
Minimal brow bossing with lifted cheek volume keeps the midface youthful in both still photos and motion.
Why neotenous faces score Stacy without extreme bone
Female PSL rewards neoteny inside the Dimorphism pillar. A face can reach 6.0+ with soft angularity if eye size, philtrum length and cheek fullness all sit at the youthful end of their corridors. Sweeney is the clearest current example, and also shows the ceiling: without stronger gonial definition the score stays in the lower half of the 6.0-7.0 Stacy tier.
Frequently asked
What is Sydney Sweeney's PSL score?
Sydney Sweeney is rated approximately 6.3 out of 8.0 on the female PSL scale (Stacy tier), driven by 6.9/8.0 Feminine Dimorphism and large palpebral fissures rather than bone angularity.
