Description

PSL Scale is an online photo analysis tool that helps users understand the visible facial proportions in a single photo. It checks photo suitability and reviews left-to-right balance, vertical proportions, horizontal spacing, and the relationship between face length and width.

The free test provides a broad 0–8 PSL Scale reference range, key measurements, a plain-language summary, and a practical suggestion without requiring sign-up. Users can compare photos taken under similar conditions to understand how lighting, angle, camera distance, and styling affect the readings.

PSL Scale is a community convention, not a clinically validated standard. The tool describes geometry in a photo; it does not provide a medical assessment or an objective verdict on attractiveness or personal worth.
