What is the PSL scale?
The PSL scale is an informal 1–8 rating of facial attractiveness that started on looks-focused forums in the 2010s; the letters are usually traced to the forums PUAHate, SlutHate and Lookism. Unlike a 1–10 scale it is meant to be harsh and bell-shaped: 4 is average, 5 is clearly above average, 6 is model-level and rare, 7 is reserved for the most celebrated faces and 8 is treated as theoretical perfection that nobody reaches. Ratings are given by forum users from photos, so they vary a lot and carry the biases of the raters. FaceTwin does not give PSL ratings. It measures symmetry, golden-ratio proportions, facial thirds, canthal tilt, jaw angle and face shape on your selfie and explains each number; the table below shows a rough PSL equivalent of our 1–10 proportions score for curiosity only.
- Informal 1–8 scale; 4 = average
- 6+ is described as model-level
- Ratings are subjective forum opinions
- FaceTwin measures, it does not rate people
The PSL scale chart
Different forums draw the chart slightly differently, but the commonly shared version looks like this. We describe each level neutrally and leave out the forum slang, which is often insulting.
| PSL | Commonly described as | Rough share of people |
|---|---|---|
| 1–2 | Well below average | Small minority |
| 3 | Below average | Common |
| 4 | Average — the middle of the curve | Largest group |
| 5 | Above average, noticeably good-looking | Roughly the top 15–20% |
| 6 | Very attractive, model-level | Top few percent |
| 7 | Exceptional; top models and actors | Extremely rare |
| 8 | Theoretical perfection | Nobody |
The shares are the forums’ own claims, not measured data. Half-steps (4.5, 5.5) are used constantly, which tells you how much of the scale is about fine distinctions that two raters rarely agree on.
PSL scale vs a 1–10 attractiveness score
Everyday 1–10 ratings are generous: people call an average face a 6 or 7. The PSL scale is deliberately compressed and pessimistic, so the same face gets a lower number. As a rough translation for curiosity, here is how the FaceTwin 1–10 proportions score lines up. Our score is based on measured geometry and calibrated on 1,196 frontal photos of public figures, whose median is 7.2:
| FaceTwin proportions score | Where it sits in our reference set | Rough PSL equivalent |
|---|---|---|
| below 6.0 | Below most reference faces | about 3 |
| 6.0 – 6.9 | Lower-middle | about 3.5 – 4 |
| 7.0 – 7.7 | Middle (median 7.2) | about 4 – 4.5 |
| 7.8 – 8.4 | Upper 20% | about 5 |
| 8.5 – 9.0 | Top few percent | about 5.5 – 6 |
| above 9.0 | Very rare in our data | 6+ |
Treat this as a novelty conversion. A geometric score cannot see skin, hair, style, expression or charisma — which are most of what people respond to — and the PSL scale itself has no fixed definition.
Why PSL ratings are unreliable
A PSL number is somebody’s opinion of a photo. That makes it fragile in predictable ways:
- Photo conditions dominate: lens distance, lighting, angle and expression can move a forum rating by a full point.
- Rater bias: small, self-selected groups rate in their own taste, which often skews by ethnicity, age and body type.
- No measurement: two raters looking at the same photo regularly disagree by one to two points, and nobody can explain the number.
- Compressed scale: when almost everyone is “a 3 to 5”, tiny differences get exaggerated into big judgements.
This is why FaceTwin measures instead. Every point in our score traces back to a landmark you can see on your own photo, and the same photo always gives the same result.
What FaceTwin measures instead of a PSL
The free analysis places 68 landmarks on your selfie and reports six insights, each with a short explanation:
| Insight | What it means | Typical value in 1,196 faces |
|---|---|---|
| Symmetry | How closely 26 left/right landmark pairs mirror | Median 79%; only 17% reach 90% |
| Golden ratio | Face length vs width and lower-face proportions compared with 1.618 | Median length/width 1.45 |
| Facial thirds | Brow-to-nose vs nose-to-chin height | Median balance 75% |
| Canthal tilt | Angle from inner to outer eye corner | Median +3.5°; 70% neutral |
| Jaw angle | Average angle at the jaw corners | Median 146° |
| Face shape | Oval, round, square, heart, oblong or diamond | 52% oval |
The weighted result is a 1–10 proportions score with a percentile against the reference faces. It is computed in your browser, nothing is uploaded and no account is needed.
Looksmaxxing without the harsh numbers
Most of the improvements people discuss under “looksmaxxing” are ordinary self-care that has nothing to do with a scale: a haircut that suits your face shape, glasses frames that balance your proportions, skincare and sleep, posture, grooming of brows and beard, clothes that fit, and photos taken from eye level at a sensible distance. Our face shape detector suggests haircuts and glasses for your shape, and the optional full report adds hairstyles, frame shapes and a colour palette for your face.
What we would steer you away from is chasing a number. Ratings communities can turn small, normal features into reasons for distress. If a score is making you anxious rather than curious, step away from it; if worries about your appearance take up a lot of your day, talking to a doctor or counsellor about body dysmorphia is a sign of strength, not weakness.
Frequently asked questions
What does PSL stand for?
It is usually traced to the initials of three looks-focused forums — PUAHate, SlutHate and Lookism — where the scale became popular in the 2010s.
What is an average PSL?
A PSL 4 is described as average, the middle of the curve. Most people fall between 3.5 and 4.5 on the scale.
Is PSL 5 good?
On the PSL scale a 5 is described as clearly above average, roughly the top 15–20% by the forums’ own claims.
How do I find my PSL rating?
PSL ratings are opinions given by forum users, so there is no objective test. FaceTwin measures your facial proportions instead and shows a rough PSL equivalent of the resulting 1–10 score for curiosity.
How does the PSL scale convert to 1–10?
Roughly, a PSL 4 corresponds to an everyday 6–7 out of 10, a PSL 5 to about 8, and a PSL 6 to about 9. See the conversion table on this page; no conversion is official.
Is my photo uploaded?
Not for the free results. The face model runs inside your browser, so your selfie, its landmarks and its face descriptor never leave your device. Only if you choose a paid portrait or report do we upload the photo once, after a separate consent, and delete it right after generation.
Does FaceTwin give PSL ratings?
No. FaceTwin measures geometry — symmetry, proportions, thirds, canthal tilt, jaw and face shape — and explains each number. It never rates other people and is for adults analysing their own photo.
Is the face test free?
Yes. The 1–10 proportions score, all six insights and the landmark overlay are free with no account.
