PSL tier chart, from Sub-5 to True Adam
Short answer
On the 1–8 PSL chart, Sub-5 is 1.0–2.9, LTN is 3.0–3.9, MTN is 4.0–4.4, HTN is 4.5–5.0, Chadlite is 5.1–6.4, Chad is 6.5–7.4, True Adam is 7.5+. The middle of the scale is 3.8–5.0. A tier names where an overall score sits; it is not a percentile of real people, and no photo can confirm the top tiers.
| Tier | Overall | What it means | What it doesn't |
|---|---|---|---|
| True Adam | 7.5+ | The far end of the scale, 7.5+: the most stretched part, where the modelled set is thinnest. | Something a photo can prove. See below: one or two photos can’t confirm the top of any scale. |
| Chad | 6.5–7.4 | From 6.5: the stretched end of the scale, where the modelled set is thinnest, so one scan can’t confirm it. | Confirmed. A flattering light or angle can lift a single scan; repeat it with matched photos before believing it. |
| Chadlite | 5.1–6.4 | From 5.1 to just under 6.5: clearly above the scale’s centre (4.4) on these photos. | That every category is strong. Read the seven categories: one standout can carry an overall. |
| HTN High-tier normie | 4.5–5.0 | The upper half of the middle band: proportions and reads sit a little above the scale's centre. | A ceiling. The potential estimate shows how much headroom the plan could add, and from which categories. |
| MTN Mid-tier normie | 4.0–4.4 | Inside the middle of the scale, around its centre (4.4). | "Average looking". The middle is where the modelled reference faces centre, not where real people rank. |
| LTN Low-tier normie | 3.0–3.9 | Below the middle of the scale (3.8–5.0), touching its lower edge at the top of the range. | A verdict on a person. Skin, hair and grooming, the parts a plan works on, count toward it too. |
| Sub-5 | 1.0–2.9 | The lowest range, below 3.0. The seven categories, taken together, scored low on these photos. | A judgement of anyone’s worth or looks in person, or that a score will stay here. Light, lens distance, angle, skin and grooming reads all move on a retake or with the plan. |
The middle of the scale: 3.8–5.0
The scale is calibrated on a modelled set of reference faces. Its centre is 4.4, and its middle half runs from 3.8 to 5.0: that band is shaded on every ruler in the app. It tells you where a number sits on the scale. It doesn't say what is “typical” of real people, so we never call it average and never turn it into a percentile.
The sample report: 4.5 overall (High-tier normie), potential 5.6. Middle of the scale 3.8–5.0.
Why the top of the scale is stretched
The top of the scale is where the modelled reference set is thinnest. It is spread out so it still reads in tenths, which makes Chad (6.5–7.4) and True Adam (7.5+) the stretched end of the scale: there, a number rests on the fewest reference faces, so one scan can't confirm it.
We say “on the modelled set” every time because the set is a statistical model of faces, not a sample of people. Nobody can honestly tell you what share of real people are Chad: there is no representative, consented photo set of everyone to measure.
Why a photo can't confirm True Adam
- Photos move numbers. Lens distance changes how wide a nose or jaw reads (the “selfie effect”1), light changes skin, and a few degrees of tilt changes proportions. Our own photo-to-photo noise on the overall is 0.6 points.
- The top is the thinnest part of any scale. Toward the top the reference set has the fewest faces, so a number up there rests on the least.
- Two photos are not a face. Expression, movement, voice, height and how someone carries themselves all count in person, and none of them is in a photo.
Our engine names a top tier like any other, from the number. What we add is the warning: a single scan at the top is a reason to repeat it with matched photos (same light, same distance, same angle), not a title.
What moves a tier, and what doesn't
The plan works on what can change: skin, sleep, hair, brows, facial hair and posture. The measured proportions (thirds, eye spacing, jaw width, symmetry) rest on bone, and mewing, gum chewing and jaw trainers don't change bone structure (see the mewing guide). That's why the potential estimate is capped at 2.0 points above your overall, and why it is an estimate, not a promise.

Questions people ask
What does the PSL scale mean?
PSL is a rating scale from online looksmaxxing communities, usually run from 1 to 8. In Chad PSL AI your tier is the PSL name for the range your overall score falls in: Sub-5 1.0–2.9, LTN 3.0–3.9, MTN 4.0–4.4, HTN 4.5–5.0, Chadlite 5.1–6.4, Chad 6.5–7.4, True Adam 7.5+. The number decides it; nothing else does.
What is Chadlite?
On our chart, Chadlite is an overall of 5.1–6.4: above the scale’s centre (4.4), up to just under Chad (6.5). It names where a score sits, not a person.
What do LTN, MTN and HTN mean?
Low-tier normie, mid-tier normie and high-tier normie: 3.0–3.9, 4.0–4.4 and 4.5–5.0 on our 1–8 chart. The middle of the scale, 3.8–5.0, where the middle half of the modelled reference faces land, falls within them.
Can an app tell me I am True Adam?
No app can confirm it from photos. A photo carries light, lens distance and angle with it; our own measured photo-to-photo noise on the overall is 0.6 points, and the top of the scale is its stretched end, where the modelled set is thinnest. If a scan reads 7.5+, repeat it with matched photos before reading anything into it.
Is my tier a percentile or a ranking?
No. The scale is calibrated on a modelled set of reference faces, not on real people, so a tier says where a number sits on the scale. We never turn it into "top X%".
Can my tier change?
Yes, a little. A change under 0.6 points on the overall is within photo noise. Skin, hair and grooming reads can move with the plan; bone structure does not change with mewing, chewing or face exercises. The potential estimate is capped at 2.0 points above your overall.
Why 1 to 8 and not 1 to 10?
The app moved to the community's 1–8 chart in October 2026. Older scans keep the 1–10 numbers they were made on, and the app never compares a score across the two scales.
