About PSL Scale

PSL Scale Test (pslscale.me) is a free online photo analysis tool for the PSL Scale, a 0–8 facial-appearance convention from online communities. Upload a clear, front-facing photo and it reviews four visible facial proportions, then shows a broad reference range with a clear summary. The site explains that the PSL Scale has no official formula and says nothing about a person's worth.

Who it is for
People curious about the PSL Scale who want a quick, private read from one photo.
Problem it solves
The PSL Scale has no official formula, and most online ratings give one opaque number with no explanation of how it was reached.
The solution
It checks photo suitability, reviews four visible facial proportions and shows a broad 0–8 PSL Scale range, with each value linked to a measurement and a chart explaining each band.
What makes it unique
It gives a range instead of a single decimal score, explains every measurement, runs the measurement in your browser without uploading the photo, and needs no sign-up.

What do DR4, DR3 and the model difference mean?
DR4:
Ahrefs' newer model. It gives more weight to links from sites with organic search traffic and rates a subdomain on its own links.
DR3:
The previous model, shown in the Ahrefs app until 1 December 2026.
Model difference:
DR4 minus DR3 for the same domain. The models calculate differently, so this is not growth or a drop; the “since” lines compare each model with itself.
